[j-nsp] Segment Routing ( SPRING )

[Julian Lucek]

Yes, as Nick mentioned we have released several SPRING features (in
15.1F5). Some of the highlights include:

Adjacency Segments for IPv4 and IPv6
Link protection of adjacency segment using LFA/Remote LFA

Node Segments for IPv4 and IPv6
Link or node protection of node segment using LFA/Remote LFA


Tunnelling Node-Label traffic over RSVP LSP

LFA/Remote LFA for LDP traffic, using SPRING node labels for the
protection path (to eliminate need for targeted LDP session between PLR and
PQ-node)


Also in 13.3 we released sub-50ms egress PE protection using SPRING
context label (see 
https://forums.juniper.net/t5/Industry-Solutions-and-Trends/Sub-50ms-PE-pro
tection-using-IGP-labels-SPRING/bc-p/262825 for more details)

At the MPLS World Congress last month, we had demos of the NorthStar
Controller doing path computation and installation of SPRING LSPs using
PCEP. (More details at
