  • Patent number: 11870751
    Abstract: An approach to establish connections between clusters having overlapping IP address ranges. A method includes receiving, at a service discovery server, from a first node in a first cluster, a service discovery request including a unique name, determining, at the service discovery server, that the unique name resolves to a destination IP address of a second node in a second cluster, determining that the destination IP address overlaps with an IP address range associated with the first cluster, in response to determining that the destination IP address overlaps with the IP address range belonging to the first cluster, configuring a gateway to expect a network connection request from the first node that includes an IP address of the gateway, and sending a service discovery response to the first node, the service discovery response including the IP address of the gateway, but not the destination IP address.

  • Patent number: 11838361
    Abstract: Systems, methods, and computer-readable media for reducing distributed storage operation latency using segment routing. In some examples, a method can involve receiving, from a client, a message identifying an intent to store or retrieve data on a distributed storage environment, and sending to the client a segment routing (SR) list identifying storage node candidates for storing or retrieving the data. The method can involve steering a data request from the client through a path defined by the SR list based on a segment routing header (SRH) associated with the request, the SRH being configured to steer the request through the path until a storage node from the storage node candidates accepts the request. The method can further involve sending, to the client device, a response indicating that the storage node has accepted the request and storing or retrieving the data at the storage node that accepted the request.

  • Publication number: 20230269223
    Abstract: Systems, methods, and computer-readable media are provided for securely advertising autoconfigured prefixes in a cloud environment. In some examples, a method can include, receiving, by a first router, an indication of an available network address prefix. In some aspects, the method can also include selecting, by the first router, a first network address prefix that is within the available network address prefix, wherein the first network address prefix provides at least one route to one or more network elements associated with the first router. In some cases, the method may further include sending, to a second router, a message including a stub registration option that indicates the first network address prefix.

  • Patent number: 10764244
    Abstract: A method includes, in a constellation of clients including a first client and a second client, receiving, at the first client, a connection request from the second client, retrieving endpoint reachability data associated with the second client and transmitting, to a server, a connection request based on the endpoint reachability data. The first client receives, from the server and based on the connection request, endpoint reachability information associated with the second client and starts a bidirectional connection with the second client. A direct or indirect tunnel is established between the first client and the second client. The tunnel is set up based on a table which maps a first connectivity option associated with the first client to a second connectivity option associated with the second client to determine whether to establish the direct tunnel or the indirect tunnel between the first client and the second client.

  • Patent number: 10680955
    Abstract: Stateless and reliable load balancing using segment routing and an available side-channel may be provided. First, a non-SYN packet associated with a connection may be received. The non-SYN packet may have first data contained in an available side-channel. Next an associated bucket may be retrieved based on a hash of second data in the non-SYN packet. The associated bucket may identify a plurality of servers. Then a one of the plurality of servers may be selected based on the first data contained in the available side-channel.
