    Abstract: Methods, network devices and computer readable media are disclosed relating to a communication network. In one embodiment, a method includes receiving a message comprising a message bit array. The message bit array identifies egress nodes for the message within a bit indexed explicit replication (BIER) domain of a communications network. A first bit position in the message bit array represents a first one or more of the egress nodes, and a bit value at the first bit position indicates that the message is to be forwarded to one of the first one or more of the egress nodes. The method further includes accessing a first forwarding table entry corresponding to the first bit position, determining whether the first bit position is an anycast bit position having multiple corresponding forwarding table entries, and forwarding the message to one of the first one or more of the egress nodes.

    Abstract: Techniques for zero-loss workload mobility with segment routing for virtual machines are presented. The techniques include receiving, by a virtual router, an electronic message destined for a first virtual machine running on a first physical machine and checking a first virtual machine state for the first virtual machine. In response to determining that it is associated with a running state indicating the first physical machine, inserting a segment routing header including an indication of the source virtual machine, the first physical machine, and the first virtual machine. In response to determining that it is associated with a migration state, inserting, by the virtual router, a segment routing header indicating the source virtual machine, an END.S for the first physical machine, the first virtual machine; and an END.SBUF for a second physical machine. The message is then routed based at least in part on the inserted segment routing header.

    Abstract: Aspects of the subject technology provide state-less load-balancing using sequence numbers to identify traffic flows. In some implementations, a process of the technology can include steps for receiving, by a load-balancer, a first packet from a source device including a request to access the service provided by a server coupled to the load-balancer, determining a load for each of the servers, wherein each server is associated with a unique set of sequence numbers, and forwarding the request to a target server selected based on its corresponding load, and wherein the request is configured to cause the target server to issue a reply to the source device. Systems and machine-readable media are also provided.

    Abstract: Systems, methods, and computer-readable media for controlling container execution. In some examples, a system can determine whether a block of a container image used in running a container is present in local storage at a host. If the block of the container image is present in the local storage at the host, then the system can use the block in the local storage to run the container at the host. If the block of the container image is absent from the local storage at the host, the system can fetch the block of the container image for the host from a container image storage node where the container image resides in its entirety. The system can use the block of the container image fetched from the container image storage node to run the container.

    Abstract: This disclosure describes methods and systems to externally manage network-to-network interconnect configuration data in conjunction with a centralized database subsystem. An example of the methods includes receiving and storing, in the centralized database subsystem, data indicative of user intent to interconnect at least a first network and a second network. The example method further includes, based at least in part on the data indicative of user intent, determining and storing, in the centralized database subsystem, a network intent that corresponds to the user intent. The example method further includes providing data indicative of the network intent from the centralized database subsystem to a first data plane adaptor, associated with the first network, and a second data plane adaptor, associated with the second network.
