With the virtualization of Data Center, the number of VM explodes.
VM can play different roles in Data Center, such as end-host, server,
firewall, and so on. Also, VM can be migrated to any places within
Data Center, even to another Data Center. Since running services
shouldn't be significantly interrupted while VM migrates, VM related
policies and dynamic information generated by any devices must be
transferred to destination devices during a proper short period.
[I.D-gu-opsa-policies-migration-00] has introduced more detail
problem statement and corresponding considerations. We wish we could
benefit from existing work to realize accurate dynamic information
migration (DIM). Therefore, we engaged in the investigation of
related IETF works right after general requirements of DIM are
defined. Since the solution for DIM has not been decided yet, and
the author can envision several kinds of solution, e.g. centralized
or distributed. It's unrealistic to enumerate all the related works
for an uncertain solution. So, in this draft, only the most related
IETF work, MIDCOM protocol, has been evaluated to find out whether it
can fully support DIM or which characteristics can be reused in DIM.
The author would like analyze other related IETF works when the WG
make further decision on DIM solution.
Following a short description of general DIM requirements, this draft
presents a brief survey of MIDCOM protocol, and then lists the gap
between MIDCOM and DIM requirements. The final section presents
possible working scope on the topic of DIM in IETF.
