Virtualization and Virtual Machine (VM) migration provide Data Center
with feasibility and improves the utilization of limited physical
resource, e.g. switches/routers, servers and links. Meanwhile, a
variety of policies (e.g. ACL, firewalls, load balancers, IPS and
QoS) are deployed in Data Center to improve system security and
gurantee SLA. Those polices are executed by rules configured or
generated on network devices. E.g. packet filtering policies are
executed by Access Control List on switches or firewalls. Another
example is Load balancer (LB) who extablishes TCP/HTTP connections
with external clients and balances connections among server farm.
During this process, TCP connection tables are dynamically generated
on LB. When VM migrates, the network devices that processing and
forward VM's packets may change. In order to keep VM's running
serives and guanrantee security on new place, VM-relevant policies,
including static policies as well as the dynamically generated
information, need to migrate with VM.
This draft describes some examples of the policies that need to
migrate with VM, the problems that need to consider when migrate
polices in Data Center. The goal is to justify that it is necessary
for IETF to make new effort on management of virtualized Data Center.
