Re: [rrg] Next topic?

Hi Tony and all,

In the past few years, RRG has done a lot of excellent research work to
explore various ideas and approaches (e.g., map&encap, id/locator split and
translation...) to addressing the Internet routing scalability issue. Today
it seems that the cloud Data Center Network (DCN) and Data Center
Interconnection (DCI) scenarios are facing a similar scalability challenge
(i.e., MAC forwarding table scalability issue). The demand for VM mobility
within the whole large L2 data center network or even across geographically
dispersed data centers is one major driving force of extending the L2 domain
scope larger and larger.

Although the reason for the MAC forwarding table scalability issue in the
DCN/DCI scenarios is not the same as that for the Internet routing
scalability issue, the ideas and approaches suitable for scaling the
Internet routing system could be utilized to deal with the MAC forwarding
table scalability issue. There are already many such attempts in reality,
especially in the academic circle. VL2 , SEATTLE and MOOSE are good examples
of them.

Hence I suggest we spend some time to consider whether we could utilize our
experience which was obtained from the past and ongoing Internet routing
scalability solution research to address the similar scalability issue
existed in the DCN/DCI scenarios, for example, we could attempt or even
develop those familiar ideas or approaches mentioned above to address the
MAC table scalability issue in the DCN/DCI scenarios.

Best regards,
Xiaohu
