Hi, All The MAP-MIB draft has been updated as -03 version.
In IETF85@Atlanta, we had a brief discussion, and the main comment was from Mark Townsley. He pointed out that the tunnel table defined in the draft would make the BR recording every CEs' addresses connected to it. This operation would somewhat counterbalance the benefit of stateless design. Basically, Mark's comment is a real issue, but not that serious. The tunnel table needs the translation/encapsulation application to provide CE address to the MIB agent, that might slightly impact the forwarding performance, but it is far from the weight of "stateful", because the the BR tunnel table is not for real-time look up, it is just a kind of logging. In the worst situation, even the MIB crash, the packet forwarding won't be bothered. The purpose we defined a tunnel table is to add some statistics of CE connecting BR. For example, the ISP might want to know how many/what CEs had been connected to a certain BR. This might be useful for service analysis and management, e.g. to static percentage of MAP enabled and the traffic, so that the ISP could learn the status of MAP deployment/usage, then might make some policies. Considering the tunnel table might still more or less bring some additional complexity, we defined it as an optional object in the MIB. We defined two map-MIB-Compliance, one is basic compliance only containing the rule table, the other is full compliance containing rule table and tunnel table. We expect your comments. Thanks a lot!
