摘要： A provider edge (PE) device and a method implemented thereon are disclosed for Ethernet virtual private network (EVPN). According to an embodiment, a first PE device performs label assignment procedure with a second PE device such that the first and second PE devices share an Ethernet segment identifier (ESI) -excluded label and know a correspondence between the ESI-excluded label and a label combination of an ESI label and a VPN label. The first PE device encapsulates a packet of broadcast, unknown unicast or multicast (BUM) traffic, with the ESI-excluded label instead of the label combination. The first PE device sends the encapsulated packet to the second PE device.

摘要： The present disclosure provides a method (300) in a router for segment routing with adjacency segment protection. The method (300) includes: activating (310) a protection of an adjacency segment in response to a failure of a link corresponding to the adjacency segment; setting (320) a link metric of the link to a value larger than a predetermined link metric threshold in an Interior Gateway Protocol, IGP, link state database at the router; flooding (330), in an IGP area, a first link state advertisement including the set link metric and an indication that the protection has been activated; removing (340) the link from the IGP link state database; and flooding (350), in the IGP area, a second link state advertisement indicating removal of the link.

摘要： A method is implemented by a network device acting as a switch in a data plane of a software defined networking (SDN) network. The switch is communicatively coupled to a controller in a control plane of the SDN network, where the controller manages packet processing functionality of the switch. The method to provide data storage resource sharing information to the controller so that the controller can manage data storage resource utilization of the switch. The method includes determining which tables stored in the switch share a data storage resource of the switch and transmitting data storage resource sharing information to the controller, where the data storage resource sharing information includes an indication of the tables that share the data storage resource.

摘要： Embodiments of the disclosure generally relate to determination of resource utilization in SDN. An SDN controller sends a query to an application layer. The query is as to utilization of a resource to be used in a network infrastructure, and the resource does not include a bandwidth resource. The prediction is then determined at the application layer based on raw utilization information in response to the query. Then, the SDN controller receives the prediction from the application layer.

摘要： A method by a network device functioning as a provider edge (PE) in an ethernet virtual private network (EVPN) to prevent transient loops between multi-home peer PEs. The method includes advertising a first EVPN label to one or more PEs that are multi-home peer PEs of the PE, advertising a second EVPN label to one or more PEs that are not multi-home peer PEs of the PE, receiving first traffic for a CE that is encapsulated with the first EVPN label as opposed to the second EVPN label, and discarding the first traffic in response to determining that a link between the PE and the CE is not operational and the first traffic for the CE is encapsulated with the first EVPN label.

摘要： A method implemented by a first network node in a communication network is provided. The method comprises: calculating one or more entropy label identifiers into one or more predefined ranges of entropy label identifiers; and transmitting a packet comprising at least the calculated one or more entropy label identifiers to one or more second network nodes. In the present disclosure, an MPLS label stack depth may be saved to mitigate stack depth challenges on the ingress node, especially for TE tunnel applications. Moreover, a light weighted solution may be achieved so that there is no impact on the transit nodes and the egress node, and on the ingress node, the switch chipset may support entropy with different ranges.

摘要： A controlling device is disclosed for Ethernet virtual private network (EVPN). According to an embodiment, the controlling device determines a first provider (P) device which is to handle broadcast, unknown unicast or multicast (BUM) traffic from a first provider edge (PE) device in an EVPN instance, on behalf of remaining PE devices in the same EVPN instance. The controlling device performs route reflection from the remaining PE devices to the first PE device such that the first PE device knows that BUM traffic needs to be forwarded to the first P device. The controlling device configures the first P device such that upon receipt of BUM traffic from the first PE device, the first P device can forward the BUM traffic to the remaining PE devices.
