    Abstract: Systems, methods, and computer-readable media are provided for load balancing requests and controlling object replication based on object popularity. A request for an object can be received at a dispatcher of a storage system from a client. Candidate storage nodes of the storage system for serving the object can be identified by the dispatcher by generating an ordered list of the candidate storage nodes using a two-dimensional consistent hashing function. Distribution of the request for the object through one or more candidate storage nodes for filling the request for the object can be facilitated according to the ordered list of candidate storage nodes. Specifically, the one or more candidate storage nodes can be configured to facilitate distribution of the request by selectively filling the request to the client using cache admission policies formed based on popularity characteristics of requested objects at the one or more candidate storage nodes.

    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.

    Abstract: 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.

    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.
