Address resolution scalability for VPN oriented data center services
Linda Dunbar · 2011
Modern data centers tend to have very large number hosts due to business demand and technology advancement like server virtualization. Server virtualization has made it convenient to dynamically create VMs when the application requires more resources, and move VMs, either from overloaded servers, or to aggregate VMs onto fewer servers to save power when demand is light. This flexibility has made variety of virtual data center services possible. This paper introduces the address resolution scaling issues in modern data centers; especially the address resolution issues for VPN oriented Data Center services. The paper also describes some alternative solutions which can make the network scale.
