Ethernet Virtual Private Network using Segment Routing - A simplified explanation of the abstract

This abstract first appeared for US patent application 18360783 titled 'Ethernet Virtual Private Network using Segment Routing

Simplified Explanation

The patent application describes the implementation of Ethernet Virtual Private Network (EVPN) using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling.

• EVPN is implemented using IPv6 SRv6 underlay network and SRv6-enhanced BGP signaling.
• Route associated with IPv6 SRv6 Segment Identifier (SID) is advertised in a route advertisement message of a routing protocol.
• SID includes encoding representing EVPN Layer 2 (L2) flooding Segment Routing end function of the router and an Ethernet Segment Identifier (ESI).
• Router performs EVPN end function on a packet containing the SID.

Potential Applications

This technology can be applied in:

• Data centers
• Service provider networks
• Cloud computing environments

Original Abstract Submitted

In one embodiment, Ethernet Virtual Private Network (EVPN) is implemented using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling. A particular route associated with a particular Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) Segment Identifier (SID) is advertised in a particular route advertisement message of a routing protocol (e.g., BGP). The SID includes encoding representing a particular Ethernet Virtual Private Network (EVPN) Layer 2 (L2) flooding Segment Routing end function of the particular router and a particular Ethernet Segment Identifier (ESI), with the particular SID including a routable prefix to the particular router. The particular router receives a particular packet including the particular SID; and in response, the particular router performs the particular EVPN end function on the particular packet.
