摘要： In an embodiment, a method exchanges routing data within a network including control and forwarding on separate devices. In the method, a first reachability information session is established between a forwarding device and a first control device and a second reachability information session is established between the forwarding device and a second control device. Also, a third reachability information session is established between the forwarding device and an external routing device. Finally, advertisements are exchanged between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. System and computer program product embodiments are also disclosed.

摘要： Disclosed herein are system, method, and computer program product embodiments for increasingly applying network resources to traffic flows based on heuristics and policy conditions. A network determines that a traffic flow satisfies a first condition and transmits a first portion of the traffic flow to a network service. A network service then inspects the first portion of the traffic flow at a first level of detail and determines that the traffic flow satisfies a second condition. The network can then transmit a second portion of the traffic flow to the network service based on the determining the traffic flow satisfies the second condition. The network service can inspect the second portion of the traffic flow at a second level of detail, wherein the inspecting at the second level of detail requires a different amount of computing resources than the inspecting at the first level of detail.

摘要： Disclosed are system, method, and computer-readable medium embodiments for a network to provide network applications and services and estimate network metrics for individual applications and services. In an embodiment, a first routing device receives a packet and determines that the packet is to be sampled. The first routing device samples the packet by storing first information associated with the packet and transmits the first information to a measurement server. The first routing device transmits the packet towards a destination according to routing information. A second routing device receives the packet and determines that the packet is to be sampled. The second routing device samples the packet by storing second information associated with the packet and transmitting the second information to the measurement server. The measurement server determines a measurement based on the first information and second information.

摘要： A user of a communication network may have specific requirements for its critical data streams. The user may require dedicated channel capacity for its critical application. A dedicated channel may be separate from a common channel carrying non-critical data of the user. The user may create policies for assigning channel capacities to its critical data streams based on various criteria. The user may also create policies on sharing the dedicated channel capacity among its different critical data streams.

摘要： A mesh network (such as a mesh Ethernet network) is subdivided into rings. For each ring, a network utilization is assessed in both the clockwise and counter-clockwise directions around the ring. A user requests a particular network service. The network rings that would be utilized by the network service are determined. A maximum utilization of all the network rings utilized by the network service in both clockwise and counter-clockwise directions is determined. The determined maximum utilization is used to determine the feasibility of provisioning the requested network service.

摘要： A network includes a plurality of endpoint routers and intermediate routers. When a new data stream is detected at any endpoint router, the first packet is sent to a virtual routing server with knowledge of the entire network topology. Based on the topology, current usage, and historical usage, the virtual routing server determined a path for the data stream and begins to update the routing tables of the intermediate routers to reflect the determined path. Until the update is complete, all packets in the data stream are routed first to the virtual routing server and then to their destination. Once the update is complete, packets in the data stream are routed directly along the determined path.
