Abstract: This paper proposes a railway data network deployment scheme by studying the technical characteristics and deployment scheme of SRv6, which adopts the network architecture of controller + forwarder to support the provision of end-to-end (E2E) bearer services; by constructing an IPv6-only network, the existing L3/L2VPN network based on IPv4 MPLS forwarding plane evolves to L3/L2VPN and EVPN based on IPv6 forwarding plane, so as to simplify network protocols, optimize network structure and release network resources. support In-band OAM network performance measurement and SLA implementation, and provide users with end-to-end SLA guarantee.
Key words: data communication network, SRv6, bearer service optimization
