  • Patent number: 11595231
    Abstract: Example implementation relates to a method for establishing a dynamic VPN tunnel between branch gateway devices based on metric data. A branch orchestrator receives metric data from VPNC device. The metric data includes data center bandwidth and processor utilization of the VPNC device. The metric data is derived from the traffic being routed via the VPNC device. When the metric data associated with traffic between a first branch gateway device and a second branch gateway device is above a Service Level Agreement (SLA), a dynamic branch to branch VPN tunnel is established to route the traffic between the first branch gateway device and the second branch gateway device. The VPN tunnel between the branch gateways can be teared when the load at the VPNC device reduces.

  • Patent number: 11570102
    Abstract: The present application relates to communications between a partner network and a wide area network (WAN) via the Internet. The WAN advertises unicast border gateway protocol (BGP) address prefixes for a plurality of front-end devices in the WAN. An agent in the partner network measures a plurality of paths to a service within the WAN. Each of the plurality of paths is associated with one of the plurality of front-end devices and a respective unicast BGP address prefix. The agent provides measurements of the plurality of paths to the WAN. The WAN selects a path within the WAN for the service. The agent receives a routing rule specifying a unicast address prefix for a selected device of the plurality of front-end devices of the WAN. The agent forwards data packets for the service to the respective border gateway protocol address prefix of the selected device via the Internet.

  • Patent number: 11539615
    Abstract: Disaggregated border gateway protocol (BGP) enables an eBGP session between an internal node an external node to continue despite failover of a perimeter through which the eBGP session is established. eBGP control traffic is trapped by a perimeter router and forwarded to a BGP speaker on the internal node through an IP tunnel. Failover is detected in response to a change in a source address of the IP tunnel over which eBGP control traffic is received. The BGP speaker announces routes to the external node that include a reference to an internal address of an active perimeter router. In response to failover, the BGP speaker announces updated routes referencing the standby router for the perimeter router.

  • Patent number: 11516125
    Abstract: Example methods and computer systems for packet handling for active-active stateful service insertion are disclosed. One example may involve a computer system detecting a packet addressed from a source address to a service endpoint address. Based on configuration information associated with the service endpoint address, the computer system may identify a first active logical service router (SR) and a second active logical SR that are both associated with the service endpoint address and configured to operate in an active-active mode. The first active logical SR may be selected over the second active logical SR by mapping tuple information to the first active logical SR. The computer system may generate an encapsulated packet by encapsulating the packet with an outer header addressed to an outer destination address associated with the first active logical SR and send the encapsulated packet towards the first active logical SR for processing according to a stateful service.

  • Patent number: 11502947
    Abstract: In one embodiment, a gateway label edge router (G-LER) receives a packet destined for a mobile domain that comprises a vehicle label edge router. The G-LER identifies, from among a plurality of primary domains, a particular primary domain that currently has a label switched connection with the mobile domain. The label switched connection connects the vehicle label edge router of the mobile domain and a cluster label edge router of the particular primary domain. The G-LER sends the packet to the cluster label edge router of the particular primary domain for transmission to the vehicle label edge router via the label switched connection. The G-LER tracks when the vehicle label edge router of the mobile domain establishes a new label switched connection with a second cluster label edge router of a different primary domain in the plurality of primary domains than that of the particular primary domain.
