  • Adaptive Private Network with Path Maximum Transmission Unit (MTU) Discovery Process
    Publication number: 20170104686
    Abstract: Systems and techniques are described for a path maximum transmission unit (MTU) discovery method that allows the sender of IP packets to discover the MTU of packets that it is sending over a conduit to a given destination. The MTU is the largest packet that can be sent through the network along a path without requiring fragmentation. The path MTU discovery method actively probes each sending path of each conduit with fragmentation enabled to determine a current MTU and accordingly increase or decrease the conduit MTU. The path MTU discovery process is resilient to errors and supports retransmission if packets are lost in the discovery process. The path MTU discovery process is dynamically adjusted at a periodic rate to adjust to varying network conditions.

  • Adaptive private network with geographically redundant network control nodes
    Patent number: 9069727
    Abstract: Systems and techniques are described which improve performance, reliability, and predictability of networks. Geographically diverse network control nodes (NCNs) are provided in an adaptive private network (APN) to provide backup NCN operations in the event of a failure. A primary NCN node in a first geographic location is operated according to a primary state machine at an NCN active state. A client node is operated according to a client state machine. A secondary NCN node in a second geographic location that is geographically remote from the first geographic location is operated according to a secondary state machine at a standby state. The three state machines operating parallel and upon detecting a change in APN state information, the secondary state machine transitions from the standby state to a secondary active NCN state and the secondary NCN node provides APN timing calibration and control to the client node.

  • Methods and apparatus for accessing dynamic routing information from networks coupled to a wide area network (WAN) to determine optimized end-to-end routing paths
    Patent number: 10348571
    Abstract: Techniques are described which apply a method for including a routing stack to provide a timely way to dynamically learn about route changes for an end to end system in the context of an adaptive private network (APN). By allowing learned routes to be assigned different services based on filtering rules, the APN can efficiently manage traffic through the WAN. Techniques for learning routes and to advertise the learned routes in different networks are also described. Upon an APN route change being detected in the APN, a route table is updated with the APN route change, wherein the route table contains routes in a local area network (LAN) and routes in a wide area network (WAN). The APN route change is selected from the route table and configured to a protocol for the LAN. The selected APN route change is advertised in the protocol to local routers in the LAN.

  • Methods and Apparatus for Providing Adaptive Private Network Centralized Management System Time Correlated Playback of Network Traffic
    Publication number: 20160197802
    Abstract: System and techniques are described for time correlated playback of traffic patterns between nodes in a network. Node statistics of data transfers between nodes are received in a control point, wherein the node statistics include a time stamp (tn) according to time at the control point of when a request statistics message was sent to each node, a node timestamp (ta) according to time at each node of when the message was received in the node, and a first delta between tn and ta that is used to determine a second delta which adjusts the node statistics. The node statistics adjusted according to the second delta are stored in a statistics database at the control point. A time stepping mechanism is used to repeatedly access the node statistics from the statistics database at a predetermined rate for playback presentation beginning from a specified start time to a specified end time.

  • Flow-Based Adaptive Private Network with Multiple WAN-Paths
    Publication number: 20160006658
    Abstract: Systems and techniques are described which improve performance, reliability, and predictability of networks without having costly hardware upgrades or replacement of existing network equipment. An adaptive communication controller provides WAN performance and utilization measurements to another network node over multiple parallel communication paths across disparate asymmetric networks which vary in behavior frequently over time. An egress processor module receives communication path quality reports and tagged path packet data and generates accurate arrival times, send times, sequence numbers and unutilized byte counts for the tagged packets. A control module generates path quality reports describing performance of the multiple parallel communication paths based on the received information and generates heartbeat packets for transmission on the multiple parallel communication paths if no other tagged data has been received in a predetermined period of time to ensure performance is continually monitored.

  • Applications and integrated firewall design in an adaptive private network (APN)
    Patent number: 10972437
    Abstract: A firewall is described that is integrated in an input stage of a packet processing pipeline so that it recognizes and has access to internal information regarding the different services, such as conduit, intranet, Internet, local vs WAN, applications, and security zones, of a communication network, such as an adaptive private network (APN). The integrated firewall is able to dynamically access the service type, respond to the service type, and adjust the service type based on conditions in the network. Since application awareness and security functions are integrated, customers can set security policies on software applications. The integrated firewall also provides automatic detection of applications, classifies applications based on domain names, steers traffic to services according to software applications, reports on software applications in passthrough traffic, and provides analysis of traffic that does not match a software application so that a user can investigate and define custom applications.

  • Adaptive private network (APN) bandwidth enhancements
    Patent number: 10924380
    Abstract: Techniques are described to automatically activate and deactivate standby backup paths in response to changing bandwidth requirements in an adaptive private network (APN). The APN includes one or more regular active wide area network (WAN) links in an active mode and an on-demand WAN link in a standby mode. The on-demand WAN link is activated to supplement the conduit bandwidth when an available bandwidth of the conduit falls below a pre-specified trigger bandwidth threshold and the conduit bandwidth usage exceeds a usage threshold of a bandwidth of the conduit that is being supplied by the active paths (BWc). The on-demand WAN link is deactivated to standby mode when an available bandwidth of the conduit is above the pre-specified trigger bandwidth threshold and the conduit bandwidth usage drops below the usage threshold of BWc techniques for adaptive and active bandwidth testing of WAN links in an APN are also described.
