  • Patent number: 10218590
    Abstract: Techniques are described for performing subscriber aware two-way active measurement protocol (TWAMP) data session provisioning between two endpoints in a computer network. For example, the disclosed techniques include extending TWAMP control messaging to include a communication mode for negotiating subscriber-aware TWAMP data monitoring. If the communication mode is supported by both endpoints, a subscriber identifier is specified when a TWAMP data session is provisioned (negotiated) over the control session. The disclosed techniques further include extending TWAMP data messaging to include the subscriber identifier in each test packet for the data session. In this way, each of the endpoints may identify a subscriber corresponding to one or more received TWAMP test packets based on the subscriber identifier included in the received TWAMP test packets.

  • Patent number: 10218611
    Abstract: Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to output Label Distribution Protocol (LDP) messages, as described herein, to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises two counter-rotating multipoint-to-point (MP2P) LSPs for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP.

  • Publication number: 20190044888
    Abstract: In some embodiments, a non-transitory processor-readable medium stores code representing instructions to be executed by a processor. The code causes the processor to receive, at an edge device, a first data unit having a characteristic. The code causes the processor to identify, at a first time, an identifier of a service module associated with the characteristic in response to each entry from a set of entries within a flow table not being associated with the characteristic. The code causes the processor to define an entry in the flow table associated with the characteristic and the identifier of the service module. The code causes the processor to send the first data unit to the service module. The code causes the processor to receive, at the edge device, a second data unit having the characteristic, and send the second data unit to the service module based on the entry.
