摘要： A method is performed at one or more entities configured to configure and provide assurance for a service enabled on a network. The service is configured as a collection of subservices on network devices of the network. A definition of the service is decomposed into a sub service dependency graph that indicates the sub services and dependencies between the subservices that collectively implement the service. Based on the subservice dependency graph, the sub services are configured to record and report sub service metrics indicative of sub service health states of the sub services. The sub service metrics are obtained from the subservices, and the subservice health states of the subservices are determined based on the sub service metrics. A health state of the service is determined based on the subservice health states. One or more of the sub services are reconfigured based on the health state of the service.

摘要： Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1 -Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

摘要： A method is provided that is performed by a network element in a network. The network element receives a packet. The network element inserts into a header of the packet, packet replication information indicating whether and to which egress interface the network element performs a replication operation on the packet, wherein the header is an In- Situ Operations, Administration and Management (IOAM) header. The network element sends the packet, with the packet replication information included in the IOAM header, in the network.

摘要： This disclosure describes techniques for implementing centralized path computation for routing in hybrid information-centric networking protocols implemented as a virtual network overlay. A method includes receiving an interest packet header from a forwarding router node of a network overlay. The method further includes determining an interest path of the interest packet and one or more destination router nodes of the network overlay. The method further includes computing one or more paths over the network overlay. The method further includes determining an addressing method for the one or more computed paths over the network overlay. The method further includes performing at least one of encoding each computed path in a data packet header, and encoding each computed path as state entries of each router node of the network overlay on each respective path. The method further includes returning the computed path information to the forwarding router node.

摘要： Techniques and mechanisms to enable a Bidirectional Forwarding Detection (BFD) Echo function to be used for IP multi-hop paths using IP encapsulation. A source device may encapsulate one or more BFD Echo packets as payloads in IP packets. The resulting IP packets may then be sent from a source device to a destination device over a multi-hop path such that one or more intermediary devices forward the IP packets onto the destination device. Upon receiving the IP packets, the destination device may echo back the one or more BFD Echo packets in the forwarding plane to indicate connectivity of the forwarding path between the devices. However, if the BFD Echo packets are not echoed back to the source device, the source device may determine that the multi-hop path has experienced a fault, and that traffic is to be rerouted through other paths.

摘要： A web browser (252) configured to execute on a network element (130(1)) receives a Hypertext Markup Language, HTML, document including HTML network service tags. The network service tags include commands to cause a corresponding network action to be taken in connection with the network element, such as configuring and/or causing information to be read from the network element. The web browser determines, based on each HTML network service tag, the command to cause the network action to be taken in connection with the network element. The web browser issues the determined command for each HTML network service tag to a corresponding application program interface, API, (254), which in turn cause the network action to be taken in connection with the network element.
