Re: [bess] 答复: SRv6 versus SR-MPLS

IMHO the question of SR-MPLS vs SRv6 is wrong as it all depends what are
you trying to accomplish in your network and what services you need to run
on it.

For example some networks need TE some do not.

Some may like to carry L2/L3VPNs some do not.

Some may think about requirements associated with special packet handling
perhaps augmented with in house development of P4 based fancy services so
do not.

Last some network are IPv4 only, some are IPv4+MPLS, some may be dual stack
and some may be IPv6 only.

For some the overhead associated with attaching additional data to each
packet matters - so do not care and do not even realize it :).

So this is very loaded question. It is like asking should I go left or
should I go right without stating your ultimate destination. Sure likely
you may end up there regardless how you turn but it may not be optimal
path.

And last as this is BESS WG ... I would really seriously consider for BESS
services use of RFC4797 and RFC7510.

Cheers,
R.
