    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, methods, and computer-readable for managing an Internet of Things (IoT) network include identifying an IoT device which is not connected to one or more communication layers of a IoT network, where the IoT network includes one or more intermediate nodes for connecting an IoT application to the IoT device. A virtual device is provided in at least one communication layer of at least one intermediate node, where the virtual device is used for modeling behavior of the IoT device. Using the virtual device as a proxy for the IoT device, operations at the at least one intermediate node while the IoT device is not connected to the at least one layer. The operations can include Operations, Administration, and Maintenance (OAM) functions. The virtual device can be withdrawn or disabled in the at least one intermediate node upon the IoT device establishing connection to the at least one layer.

    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: According to one aspect, a method includes obtaining a segment routing (SR) packet from an endpoint via a first router at a first server along a path, the SR packet including an SR list and a last address, the last address being an address of a requested service. The method also includes determining, at the first server, whether the requested service is available from the first server, wherein determining whether the requested service is available from the first server includes opening the SR packet, parsing an SR header of the SR packet, and performing a lookup in a service table. Finally, the method includes modifying the SR packet at the first server when it is determined that the requested service is not available from the first server; and forwarding the SR packet along the path.

    Abstract: The disclosure provides a system, method and computer-readable storage device embodiments. Some embodiments can include an IPv6-centric distributed storage system. An example method includes receiving, at a computing device, a request to create metadata associated with an object from a client, creating the metadata based on the request and transmitting the metadata and an acknowledgment to the client, wherein the metadata contains an address in a storage system for each replica of the object and wherein the metadata can be used to write data to the storage system and read the data from the storage system. There is no file system layer between an application layer and a storage system layer.
