Appl. No.:

17/349344

Inventors:

- Hanover MD, US
Peng He - East Brunswick NJ, US
Himanshu Shah - Hopkinton MA, US
Selvamani Ramasamy - San Jose CA, US

International Classification:

H04L 12/707
H04L 12/46

Abstract:

Systems and methods for extending Ethernet Virtual Private Network (EVPN) protocols are provided. A Link Aggregation Group (LAG), according to one implementation, includes a plurality of Ethernet Segments (ESs) and a plurality of service ports configured to communicate over the plurality of ESs. The service ports are configured to enable an operator device to access an EVPN to receive Layer 2 (L2) and Layer 3 (L3) Ethernet services. Also, the service ports are configured to enable the operator device to operate with multi-homing functionality to receive the L2 and L3 Ethernet services via redundant paths associated with the plurality of ESs. The services ports are further configured to respond to operator commands, whereby the operator commands include one or more operator commands related to switching among the redundant paths.

Abstract:

A node in a Segment Routing network includes circuitry configured to signal first service Segment Identifiers (SIDs), for one or more first Ethernet services configured at the node, to other nodes in the Segment Routing network, receive second service SIDs for one or more second Ethernet services configured at the other nodes in the Segment Routing network, and configure the second service SIDs for one or more second Ethernet services. The first service SIDs and the second service SIDs can be signaled by one of Interior Gateway Protocol (IGP) and Border Gateway Protocol (BGP).

Abstract:

A node in a Segment Routing network includes a plurality of ports and a switching fabric between the plurality of ports, wherein, for an Ethernet Tree (E-tree) service, a port is configured to transmit a packet with a plurality of Segment Identifiers (SID) including a first SID, a second SID, and a third SID, wherein the first SID identifies one of multicast, ingress replication for broadcast, and a destination node including any of a node SID and an anycast SID, wherein the second SID identifies a service including the E-tree service, and wherein the third SID identifies a source of the packet. A second port of the node is connected to a customer edge, and wherein the third SID is based on whether the customer edge is a leaf node or a root node in the E-tree service.
