    摘要： Systems, methods, and computer-readable media for enabling container networking are disclosed. In one aspect, a method includes receiving a request from a first network container on a source server to establish a data session with a second network container on a destination server; determining a destination switch of the destination server based on the request; identifying a communication tunnel between the source server and the destination server; generating a data stream to be embedded in the pre-established communication tunnel, wherein a communication protocol associated with the request is different from a communication protocol used by the data stream; receiving a data packet to be sent to the destination container; mapping the data packet to the data stream; and sending the data packet to the destination server via the data stream over the communication tunnel.

    摘要： In one embodiment, a device obtains path probing data for paths between a set of network nodes wherein a first subset of the set of network nodes are operated by a provider of an online application or service and a second subset of the set of network nodes operated by affiliates. The device generates, based on the path probing data, a performance model of path performances between clients in different geolocations and the online application or service via each of the set of network nodes. The device determines, based on the performance model, a particular node in the second subset should be used as a point of presence for clients located in a particular one of the different geolocations to access the online application or service. The device configures a network overlay including the first subset and the particular node as points of presence for the online application or service.

    摘要： Systems and methods provide for segment routing (SR) with fast reroute in a container network. An SR ingress can receive a packet from a first container destined for a container service. The ingress can generate an SR packet including a segment list comprising a first segment to a first container service host, a second segment to a second service host, and a third segment to the service. The ingress can forward the SR packet to a first SR egress corresponding to the first host using the first segment. The first egress can determine whether the first service and/or host is reachable. If so, the first egress can forward the SR packet to the first host or the packet to the service. If not, the first egress can perform a fast reroute and forward the SR packet to a second SR egress corresponding to the second host using the second segment.

    摘要： In one embodiment, a method includes identifying a change in network topology at a network device, transmitting a test packet from the network device to determine if an adjacent network device located in a backup path has converged following the network topology change, and updating a forwarding information base at the network device in response to the network topology change if a response to the test packet indicates that the adjacent network device has converged. An apparatus and logic are also disclosed herein.
