Abstract: Novel tools and techniques are provided for implementing dynamic border gateway protocol (“BGP”) host route generation based on domain name system (“DNS”) resolution. In various embodiments, a computing system may receive, from a user device via a first network, a request to establish a communications link with an external device via a second network that is separate from the first network, based on a first uniform resource identifier (“URI”) indicative of a network location of the external device. The computing system may query a DNS resolver for an Internet Protocol (“IP”) address corresponding to a valid current IP address, based on the first URI, and may advertise the IP address and/or a route based on the IP address. A communications link may be established between the user device and the external device based on the IP address and/or the route.

Abstract: A routing system can provide a Dynamic-Hybrid Forwarding Information Base (DHFIB). A control component of the routing system can build a routing table that includes routing information (e.g., prefixes, addresses, etc.) for use by a first routing component. The routing table can be ordered or ranked based on traffic information from the first routing component. Then, the control component can create the DHFIB from the routing table, wherein the DHFIB is a portion of the routing table and related to the first routing component. As such, the portion of the routing table selected for the DHFIB can be the set of prefixes in the routing table that represent the most frequently routed or most important prefixes in the routing table. Finally, the control component can forward the DHFIB to the first routing component to allow the routing component to route communications.

Abstract: A traffic controller device for distributing or otherwise controlling the distribution of routing information may be included in a telecommunications network. The traffic controller may receive routing tables from a plurality of network devices, such as one or more provider edge devices of the network. The traffic controller, upon receiving the routing information from the provider edge devices, may generate a routing table associated with each device providing the routing information. The traffic controller may also provide updates to one or more of the networking devices associated with the controller. The traffic controller may alter or update, at the traffic controller, the routing table associated with the target provider edge device based on the network policy. The routing information in the routing table for that device and maintained by the traffic controller may be updated with a new route or new local preferred parameter value.

Abstract: Aspects of the present disclosure involve a CDN utilizing a Direct Server Return (DSR) request command to create a tunnel from one content server to another content server of the CDN. Through the DSR tunnel, a request for content may be served from a content server that is more advantageous for the CDN for any number of reasons, such as from a content server that is logically closer to the content server. In determining when a DSR tunnel is created to provide the content, the CDN may access a database storing various information concerning the CDN, such as the location of egress gateways of the CDN in relation to one or more content servers, connecting network location information, the capabilities of one or more content servers, and/or load information of available content servers.

Abstract: Direct to systems and methods for a service activation system in a telecommunications network that utilizes one or more generic container files for building the configuration file to instantiate the service on the network. A request for service from a network may be received from an order entry system that includes specific information about the requested service. A collection of generic configuration files may be selected based on the information included in the service order and arranged to build a configuration file to be executed on the network. The service activation system may also include a component or group of components to verify a received service order and alter the service order with default information or data where applicable. The configuration file may also be executed on the network through one or more drivers communicating with the affected devices to configure the one or more network devices.

Abstract: Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

Abstract: A security platform of a data network is provided that includes security services for computing devices in communication with the data network. The security platform may apply a security policy to the computing devices when accessing the Internet via a home network (or other customer network) and when accessing the Internet via a public or third party network. To provide security services to computing devices via the home network, the security platform may communicate with a security agent application executed on the router (or other gateway device) of the home network. In addition, each of the devices identified by the security profile for the home network may be instructed or otherwise be provided a security agent application for execution on the computing devices. The security agent application may communicate with the security platform when the computing device connects to the Internet over a third party or public access point.

Abstract: Examples of the present disclosure describe systems and methods relating to adaptive virtual services. In an example, a user specifies a device configuration for a platform device. As a result, a service provider installs selected virtual-network functions and defines network connections as specified by the device configuration. Management software may also be installed, thereby enabling the service provider to communicate with and remotely manage the platform device. The installed virtual-network functions are activated on the platform device once it is delivered to the user. In some instances, the user changes the device configuration. For example, the user may install new virtual-network functions, reconfigure or remove existing virtual-network functions, or change defined network connections. As a result, the service provider reconfigures the platform device accordingly. Thus, the user need not purchase new specialized hardware in order to change the available functions of the computer network.

Abstract: Systems and methods for routing traffic through a network along Label-Switched Paths (LSPs) that may extend across multiple autonomous systems include performing Internet Protocol (IP) routing lookups as a packet is transmitted along the LSP. In one implementation, a packet having a predetermined value (which may be inserted by an upstream network device) is received at a network device after travelling along a first segment of an LSP. In response to identifying the predetermined label value of the packet, the network device may perform an IP routing lookup using IP routing information included in the packet to identify a next hop for the packet. The network device may then update a label of the packet such that the packet is routed along a second segment of the LSP and transmit the communication packet to the next hop.

Abstract: Aspects of the present disclosure involve utilizing network threat information to manage one or more security devices or policies of a communication network. The security system may receive threat intelligence data or information associated with potential threats to a communications network and process the threat intelligence data to determine one or more configurations to apply to security devices of a network. The system may then generate a rule or action to respond to the identified attack, such as a firewall rule for a firewall device to block traffic from the source of the attack. The threat intelligence information may include a confidence score indicating a calculated confidence in the identification of the malicious communications, which may be utilized by the system to determine the type of action taken on the security devices of the network in response to the information or data.

Abstract: Systems and methods for conference security based on user groups are disclosed. In examples, a set of attendees (e.g., in a collaboration group) may be allowed access to a meeting by a host user with a specified access permission. The collaboration group may be in the network hosting the meeting or outside of the network. An attendee requesting access to the meeting may be verified based on the attendee's identity and membership status of the collaboration group. If an attendee's identity is not identified or if the attendee is not a member of the collaboration group, the requesting attendee may be denied access to the meeting. If the requesting attendee's identity is verified and the attendee is a member of the collaboration group, the attendee is allowed access to the meeting with their specified access permission.

Abstract: The present application describes a system and method for determining a latency between a client device and various servers of a networking system.

Abstract: Implementations described and claimed herein provide systems and methods for an optical domain controller for managing and maintaining a record of network component configuration and interconnections. The optical domain controller detects changes in a configuration of optical network elements in response to a requested service from the network, coordinates additional changes in configurations to optical network elements that may be affected by the detected change, communicates with the optical network elements to incorporate the changes to the configurations of the network element, and stores the configurations and states of the network elements. The use of the optical domain controller may thus replace or supplement a database storing network configuration information by automatically managing changes to the network as new services are instantiated directly on the optical network elements.
