Re: [bess] 答复: SRv6 versus SR-MPLS

I second Robert.

SRv6 is yet another tool in the overall toolset, and, as with every tool, there are situations (use cases) where using this particular tool might be the optimal solution, whereas there are use cases, where other tools do the job better, and, there are use cases where using this particular tools is complete misunderstanding. There as are as well use cases, where combinations of multiple tools bring the best effect.

Thanks,
Krzysztof
