Abstract:
Source Packet Routing in Networking (SPRING) architecture for unicast
traffic has been proposed to cope with the use cases in traffic
engineering, fast re-reroute, service chain, etc. It can leverage
existing MPLS dataplane without any modification. In fact, the label
stack capability in MPLS would have been utilized well to implement
flexible path programming to satisfy all kinds of requirements of
service bearing. But in the distributed environment, the flexible
programming capability is difficult to implement and always confined
to reachability. As the introducing of central control in the
network, the flexible MPLS programming capability becomes possible
owing to two factors: 1. It becomes easier to allocate label for
more purposes than reachability; 2. It is easy to calculate the MPLS
path in a global network view. Moreover, the MPLS path programming
capability can be utilized to satisfy more requirements of service
bearing in the service layer which is defined as service-oriented
MPLS path programming. This document defines the concept of MPLS
path programming, then proposes use cases, architecture and protocol
extension requirements in the service layer for the architecture of
Source Packet Routing in Networking (SPRING).
