- AT&T

The concepts and technologies disclosed herein are directed to software-defined wide-area network (“SD-WAN”) self-service for service assurance. The proposed SD-WAN self-service solution can be used for any policy-driven system that automatically troubleshoots the problems resulting from hybrid SD-WAN network activities, including virtual private network (“VPN”), IP tunnel, IPSec, and security policies. According to one aspect disclosed herein, a method can check network configurations, analyze switch responses, and locate network problems quickly. Moreover, the method can test the functionality of a rules-based troubleshooting software effectively without employing expensive testing equipment and with minimal human intervention. Without the disclosed solution, telecommunications service providers may have to hire more software engineers who understand SDN and cloud technologies to effectively troubleshoot SD-WAN network connectivity issues, including issues caused by virtual network function (“VNF”), virtual machine (“VM”), and SDN switches.

Description
BACKGROUND

Software-defined wide area networks (“SD-WANs”) provide robust network connectivity and cost-saving benefits for companies to fulfill their telecommunications service needs. SD-WAN alone, however, is not as reliable as traditional multi-protocol label switching (“MPLS”). As a result, some telecommunications service providers now offer hybrid SD-WAN solutions that integrate benchmark features of MPLS-based virtual private networks (“VPNs”) and the robust nature of SD-WAN. This hybrid solution inevitably increases network complexity. Network operations personnel must be equipped to handle SD-WAN problems caused by VPN, IP tunnel, and IPSec, as well as security policies. Therefore, automating SD-WAN fault management is critical for telecommunications service providers to deploy hybrid SD-WAN service offerings.

SUMMARY

Concepts and technologies disclosed herein are directed to SD-WAN self-service for service assurance. According to one aspect of the concepts and technologies disclosed herein, an SD-WAN self-service automation platform can monitor an SD-WAN network for a network alarm. The SD-WAN self-service automation platform can create a service chain for the SD-WAN network. The SD-WAN self-service automation platform can determine whether a network alarm was found. In response to determining that a network alarm was found, the SD-WAN self-service automation platform can confirm the network alarm and correlate the network alarm with a support ticket. In response to determining that no network alarms were found, the SD-WAN self-service automation platform can collect a network response from an IP tunnel in the SD-WAN network. The SD-WAN self-service automation platform can verify any SD-WAN diagnoses on a VPN connection supported by the SD-WAN via the IP tunnel. The SD-WAN self-service automation platform can determine whether a VPN problem was found. In response to determining that a VPN problem was found, the SD-WAN self-service automation platform can verify layer 1, layer 2, and layer 3 testing of the SD-WAN. In response to determining that no VPN problems were found, the SD-WAN self-service automation platform can determine whether the IP tunnel is active. In response to determining that the IP tunnel is inactive, the SD-WAN self-service automation platform can verify a configuration of the IP tunnel and reset the IP tunnel. In response to determining that the IP tunnel is active, the SD-WAN self-service automation platform can determine whether an IPSec connection is active. In response to determining that the IPSec connection is inactive, the SD-WAN self-service automation platform can confirm a configuration of the IPSec connection and can recreate the IPSec connection. In response to determining that the IPSec connection is active, the SD-WAN self-service automation platform can determine whether a security policy configuration for the IPSec connection is functioning correctly. In response to determining that the security policy configuration for the IPSec connection is not functioning correctly, the SD-WAN self-service automation platform can confirm the security policy configuration and can recreate the IPSec connection. In response determining that the security policy configuration for the IPSec connection is functioning correctly, the SD-WAN self-service automation platform can determine whether an IP protocol status for the IPSec connection is functioning correctly. In response to determining that the IP protocol status for the IPSec connection is not functioning correctly, the SD-WAN self-service automation platform can confirm an IP protocol configuration and can re-establish the IPSec connection. In response to determining that the IP protocol status for the IPSec connection is functioning correctly, the SD-WAN self-service automation platform can verify a ping test to a customer site and can send simulated IP traffic over an SD-WAN service path. The SD-WAN self-service automation platform can determine whether the ping test was successful and whether the SD-WAN service path is active. In response to determining that the ping test was successful and the SD-WAN service path is active, the SD-WAN self-service automation platform can confirm that network tests are functioning correctly and that service is to be restored. In response to determining that the ping test was unsuccessful or that the SD-WAN service path is inactive, the SD-WAN self-service automation platform can confirm a possible network failure.

In some embodiments, the SD-WAN self-service automation platform can provide a self-service portal through which an SD-WAN self-service feature can be activated. The SD-WAN self-service feature can be provided to a customer associated with a customer site that utilizes, at least in part, the SD-WAN (e.g., to access dedicated Internet, VPN, or private cloud services).

In some embodiments, the SD-WAN self-service automation platform can analyze a response from an external system via an application programming interface. The external system can include a ticketing system, an inventory system, a testing system, or an alarm monitoring system. In some embodiments, the SD-WAN self-service automation platform can analyze a response associated with layer 1 traffic, layer 2 traffic, or layer 3 traffic.

DETAILED DESCRIPTION

The concepts and technologies disclosed herein are directed to SD-WAN self-service for service assurance. The proposed SD-WAN self-service solution can be used for any policy-driven expert system that automatically troubleshoots the problems resulting from hybrid SD-WAN network activities, including VPN, IP tunnel, IPSec, and security policies. According to one aspect disclosed herein, a method can check network configurations, analyze switch responses, and locate network problems quickly. Moreover, the method can test the functionality of a rules-based troubleshooting software effectively without employing expensive testing equipment and with minimal human intervention. Without the disclosed solution, telecommunications service providers may have to hire more software engineers who understand SDN and cloud technologies to effectively troubleshoot SD-WAN network connectivity issues, including issues caused by VNF, VM, and SDN switches. Thus, this labor-intensive solution is not only expensive, but also not immune to human error.

Turning now to FIG. 1, an operating environment 100 for implementing embodiments of the concepts and technologies disclosed herein will be described. The operating environment 100 includes an SD-WAN 102 that can connect multiple customer sites 104A-104N, such as, but not limited to, data centers, branch sites, and public cloud services, operating at the edge of the SD-WAN 102. In the illustrated example, the customer site1 104A includes a universal customer premises equipment1 (“CPE1”) 106A that can host various virtual network functions (“VNFs”), such as an SD-WAN function1 108A and one or more other functions' 110A (e.g., switches, routers, gateways, firewalls, deep packet inspection, and/or the like) operating as part of a customer network1 112A. Similarly, the customer siteN 104N includes a CPEN 106N that can host various virtual network functions, such as an SD-WAN function 108N and one or more other functionsN 110N (e.g., switches, routers, firewalls, deep packet inspection, and/or the like) operating as part of a customer networker 112N. The SD-WAN functions 108A-108N enable the uCPEs 106A-106N, respectively, to connect to the SD-WAN 102, which can utilize various SD-WAN components 116 to establish and manage SD-WAN transports 114A-114N that facilitate data transport across the SD-WAN 102 (e.g., between the customer sites 104A, 104N). The SD-WAN transports 114A-114N can utilize IP tunneling and/or IP security (“IPSec”) tunneling to provide connectivity for one or more MPLS VPN 118, the Internet 120, and/or one or more private cloud networks 122. The SD-WAN components 116 can include various VNFs and/or hybrid network functions, such as routers, gateways, switches, firewalls, and the like. In addition, the SD-WAN components 116 can include one or more SD-WAN controllers and one or more SD-WAN orchestrators. Briefly, the SD-WAN orchestrator(s) can manage the SD-WAN 102 by overseeing traffic that traverses the SD-WAN 102 and can apply policy and protocol established by the network operator. The SD-WAN controller(s) can provide centralized management and enables network operators to view the entirety of the SD-WAN 102 and set policy to be applied by the SD-WAN orchestrator(s). Those skilled in the art will appreciate that the illustrated SD-WAN 102 is a simplified example of an SD-WAN deployment. Due to the unique requirements of the customers at the customer sites 104, the SD-WAN 102 may be configured in numerous ways using various SD-WAN components 116 to provide connectivity to the MPLS VPN(s) 118, the Internet 120, the private cloud networks(s) 122, and/or other networks (not shown), in any combination. As such, the illustrated example should not be construed as being limiting in any way.

According to embodiments, an SD-WAN self-service automation platform 124 can automatically troubleshoot problems resulting from SD-WAN network activities, such as VPN, IP tunnel, IPSec, and the implementation of security policies. The SD-WAN self-service automation platform 124 can check network configurations, analyze switch responses, and locate network problems quickly. Moreover, the SD-WAN self-service automation platform 124 can test the functionality of rules-based troubleshooting applications 126 without employing expensive testing equipment in network clouds and with minimal human intervention. The SD-WAN self-service automation platform 124 can provide a policy-driven and application programming interface (“API”)-powered software tool that utilizes modern programming language (e.g., XML, Java, and Python) to collect responses from the rules-based troubleshooting applications 126 used by fault management systems, performance monitoring systems, live inventory systems, and testing systems (shown collectively as “support systems 128”). The SD-WAN self-service automation platform 124 can present real-time SD-WAN network performance data via a self-service portal 130. The self-service portal 130 can provide access to all desired network performance responses that are either specific to a particular API invocation or to a particular service such as SD-WAN service.

The SD-WAN self-service automation platform 124 can provide the following high-level automation steps for SD-WAN self-service automation. A more detailed methodology for implementing these steps is illustrated and described herein with reference to FIG. 2. The SD-WAN self-service automation platform 124 can monitor alarms 132 from the SD-WAN components 116 (e.g., AT&T FlexWare, vHNF, vHNGW, IP Tunnel, VPN PE, dedicated Internet PE, combinations thereof, and/or the like). The SD-WAN self-service automation platform 124 can create a service chain 134 of the SD-WAN transport 114 types and the SD-WAN components 116 based on real-time data. The SD-WAN self-service automation platform 124 can verify alarm correlation for any network outage and ticket correlation for service trouble tickets to network outage tickets. The SD-WAN self-service automation platform 124 can execute SHOW commands to verify IP interface testing on the ports of the SD-WAN components 116 when no alarm 132 is found. The SD-WAN self-service automation platform 124 can examine tunnel interface responses to verify IP tunnel connectivity when the MPLS VPN 118 is active and connected device(s) is/are free of trouble. The SD-WAN self-service automation platform 124 can check IP security responses to verify IPSec connection when an IPSec tunnel is active. The SD-WAN self-service automation platform 124 can examine policy responses to verify security policies 136 and security configurations 138 including security association, encapsulation security payload, and security authentication header. The SD-WAN self-service automation platform 124 can verify IP routing protocol responses to check Open Shortest Path First (“OSPF”) and Enhanced Interior Gateway Routing Protocol (EIGRP) when no security issues exist. The SD-WAN self-service automation platform 124 can verify ticket activities, including auto-closure, auto-referral, and auto-notification based on a diagnosed result when a root cause is found. The SD-WAN self-service automation platform 124 can simulate service path traffic to verify customer service connectivity when a problem is fixed or when no problem is found.

The disclosed method can analyze the desired network performance response from external applications, such as the rules-based troubleshooting applications 126, by utilizing various APIs. The APIs can be capable of connecting to live testing equipment (not shown; may be part of the support systems 128) or the SD-WAN 102. The following example demonstrates how various ports 140 of the SD-WAN self-service automation platform 124 can connect to various support systems 128 and applications provided via the SD-WAN 102. Some of the support systems 128 are particular to AT&T, but other network operators may have similar systems.

It should be understood that the operations of the method disclosed herein is not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be added, omitted, and/or performed simultaneously, without departing from the scope of the concepts and technologies disclosed herein.

It also should be understood that the method disclosed herein can be ended at any time and need not be performed in its entirety. Some or all operations of the method, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer storage media, as defined herein. The term “computer-readable instructions,” and variants thereof, as used herein, is used expansively to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations including single-processor or multiprocessor systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.

Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. As used herein, the phrase “cause a processor to perform operations” and variants thereof is used to refer to causing a processor of a computing system or device, or a portion thereof, to perform one or more operations, and/or causing the processor to direct other components of the computing system or device to perform one or more of the operations.

For purposes of illustrating and describing the concepts of the present disclosure, operations of the method disclosed herein are described as being performed alone or in combination via execution of one or more software modules, and/or other software/firmware components described herein. It should be understood that additional and/or alternative devices and/or network nodes can provide the functionality described herein via execution of one or more modules, applications, and/or other software. Thus, the illustrated embodiments are illustrative, and should not be viewed as being limiting in any way.

The method 200 begins and proceeds to operation 202. At operation 202, the SD-WAN self-service feature is initiated. The SD-WAN self-service feature can be activated through the self-service portal 130 to address an issue with some aspect of the operation of the SD-WAN 102. For example, a user such as a network engineer, network operator personnel, customer, or other user can use the self-service portal 130 to initiate the SD-WAN self-service feature. Additionally or alternatively, the SD-WAN self-service feature may be initiated in response to a specific event, which may be defined, for example, by a customer or the network operator.

From operation 202, the method 200 proceeds to operation 204. At operation 204, the SD-WAN self-service automation platform 124 monitors network alarms 132 related to the operation of the SD-WAN 102. The network alarms 132 may originate from any of the SD-WAN components 116. From operation 204, the method 200 proceeds to operation 206. At operation 206, the SD-WAN self-service automation platform 124 creates the service chain 134 data related to the SD-WAN 102. From operation 206, the method 200 proceeds to operation 208. At operation 208, the SD-WAN self-service automation platform 124 determines whether any network alarm 132 was found. If so, the method 200 proceeds to operation 210. At operation 210, the SD-WAN self-service automation platform 124 can confirm the network alarm(s) 132 and correlate the network alarm(s) 132 with any support tickets (e.g., generated by the support systems 128).

At operation 222, the SD-WAN self-service automation platform 124 determines whether any IP tunnel is active. If not, the method 200 proceeds to operation 224. At operation 224, the SD-WAN self-service automation platform 124 verifies the tunnel configuration (VRF, AS) and resets the IP tunnel. The method 200 can end at operation 224. If, however, at operation 222, the SD-WAN self-service automation platform 124 determines that an IP tunnel is active, the method 200 proceeds to operation 226.

At operation 226, the SD-WAN self-service automation platform 124 verifies any IPSec elements. From operation 226, the method 200 proceeds to operation 228. At operation 228, the SD-WAN self-service automation platform 124 determines if the IPSec connections are functioning correctly. If not, the method 200 proceeds to operation 230. At operation 230, the SD-WAN self-service automation platform 124 can confirm the IPSec configuration and re-create the IPSec connection. The method 200 can end at operation 230. If, however, at operation 228, the SD-WAN self-service automation platform 124 determines that the IPSec connection is functioning correctly, the method 200 proceeds to operation 232.

At operation 232, the SD-WAN self-service automation platform 124 verifies the security policy configuration. From operation 232, the method 200 proceeds to operation 234. At operation 234, the SD-WAN self-service automation platform 124 determines whether the security policy configuration is functioning correctly. If not, the method 200 proceeds to operation 236. At operation 236, the SD-WAN self-service automation platform 124 confirms the security policy configuration and re-creates the IPSec connection. The method 200 can end at operation 236. If, however, at operation 234, the SD-WAN self-service automation platform 124 determines that the security policy configuration is functioning correctly, the method 200 proceeds to operation 238.

At operation 240, the SD-WAN self-service automation platform 124 determines if the IP protocol configuration is functioning correctly. If not, the method 200 proceeds to operation 242. At operation 242, the SD-WAN self-service automation platform 124 confirms the IP protocol configuration and re-establishes the connection. The method 200 can end at operation 242. If, however, at operation 240, the SD-WAN self-service automation platform 124 determines that the IP protocol configuration is functioning correctly, the method 200 proceeds to operation 244.

At operation 244, the SD-WAN self-service automation platform 124 verifies a ping test to each customer site 104, and sends simulated IP traffic over the SD-WAN service path (e.g., provided, at least in part, by one or more of the SD-WAN transports 114). From operation 244, the method 200 proceeds to operation 246. At operation 246, the SD-WAN self-service automation platform 124 determines if all ping tests are functioning correctly and whether the service connection is active. If so, the method 200 proceeds to operation 248. At operation 248, the SD-WAN self-service automation platform 124 confirms that network tests are functioning correctly and that service has been restored. The method 200 can end at operation 248. If not, the method 200 proceeds to operation 250. At operation 250, the SD-WAN self-service automation platform 124 confirms a possible network failure. The method 200 can end at operation 250.
