As core participant of the Segment Routing Technology, he holds multiple patents and has contributed and authored IETF documents in network communications. Gaurav has been actively involved in defining the Segment Routing technology and its focus on Enterprise, SP and DC customers.
Segment Routing (SR) is an architecture based on the source routing paradigm that seeks the right balance between distributed (network-wide) intelligence and centralized (controller-based) programmability. Commercial deployments of SR using the MPLS forwarding plane have been very successful. The focus of this presentation will be on IPv6 Segment Routing (SRv6). SRv6 enhances the properties of network simplification, strict SLA enforcement, automation and scaling (stateless fabric) pioneered by SR-MPLS. SRv6 extends the implementation of network programming by allowing “any” instruction to be bound to a segment; for example: forwarding and user-defined instructions. SRv6 use-cases expand into Network Function Virtualization (NFV), Service Chaining, Spray, 5G mobile etc. Comcast operators will discuss their Segment Routing use-cases such as Spray which helps transition their service provider network to something smarter with increased IPv6 capabilities, IPv4 transition mechanisms, and enhanced service delivery. Comcast will also discuss other lead operators use-cases such as VPN overlay, NFV, Service Chaining and 5G mobile and how they are utilizing the Segment Routing (SRv6) technology. In addition, the support of SRv6 in open source projects (Linux Mainline and Vector Packet Processing (VPP) platform) provides Comcast, other network operators and researchers with powerful tools for the validation and deployment of the technology. SRv6 brings untapped potential and innovation to the network layer that translates into impactful opportunities.
