Abstract:
Enhanced VPNs aim to deliver VPN services with enhanced
characteristics, such as guaranteed resources, latency, jitter, etc.,
so as to support customers requirements on connectivity services with
these enhanced characteristics. Enhanced VPN requires integration
between the overlay VPN connectivity and the characteristics provided
by the underlay network. A Network Resource Partition (NRP) is a
subset of the network resources and associated policies on each of a
connected set of links in the underlay network. An NRP could be used
as the underlay to support one or a group of enhanced VPN services.
Segment Routing (SR) leverages the source routing paradigm. A node
steers a packet through an ordered list of instructions, called
"segments". A segment is referred to by its Segment Identifier
(SID). SIDs can represent topological or service based instructions.
SIDs can further be associated with a set of network resources used
for executing the instruction. Such SIDs are called resource-aware
SIDs. A group of resource-aware SIDs may be used to build SR based
NRPs, which provide customized network topology and resource
attributes required by one or a group of enhanced VPN services.
This document describes an approach to build SR based NRPs using
resource-aware SIDs. The SR based NRP can be used to deliver
enhanced VPN services in SR networks.
