Solution Benefits

SRv6-Based Transport Solution

Most of the service provider networks rely on Multiprotocol Label Switching (MPLS) transport. MPLS transport is based on Label Distribution Protocol (LDP), traffic engineering with Resource ReSerVation Protocol (RSVP), or newer deployments that replace LDP or RSVP control plane for label distribution with Interior Gateway Protocol (IGP) extension (Segment Routing). SRv6 is a new transport mechanism that replaces MPLS encapsulation with IPv6 encapsulation. It retains most MPLS benefits and adds new features to service provider networks.

With these capabilities, you can:

  • Increase network scalability: SRv6 allows prefix aggregation or summarization at domain (autonomous system, area) boundaries. This is a powerful toolset for high-scale deployments in large networks, eliminating the need to exchange unique loopbacks or labels across domain boundaries.
  • Simplify operations: Compared to LDP or RSVP, SRv6 reduces the number of protocols required to operate the network. You can move away from traffic-handling protocols like LDP or RSVP in underlay networks in favor of SRv6, where corresponding information is distributed through IS-IS extensions.
  • Reduce cost to serve: SRv6 potentially enables unified encapsulation across all network segments, including data centers, access and aggregation networks, and wide area networks. Encapsulation conversion at domain boundaries (for example, between VxLAN in DC and MPLS in WAN) is no longer required. This approach reduces operational expenses (Opex) and capital expenditures (Capex) by simplifying DC gateways.
  • Improve the user experience: SRv6 enables new use cases, such as Service Function Chaining (SFC) and multi-topology routing with SRv6 Flexible Algorithms.
