it seems Google decided to reach out to open community and use the freely available network stack for it’s own MPLS prototyping. the effect is complete MPLS LSR prototype and it’s even described by recent NANOG 50 talk and video. of course it’s quite interesting to see Google experimenting with that kind of solutions - maybe it will be connected to OpenFlow as non-academic exercise? will it become mainstay of new service provider networks? let’s talk about it during next, march edition of PLNOG.
