A Policy-aware Switching Layer for Data Centers
D. Joseph, A. Tavakoli, I. Stoica, “A Policy-Aware Switching Layer for Data Centers,” ACM SIGCOMM Conference, (August 2008). [PDF] Summary Middlebox (e.g., firewalls, load balancers etc.) management in existing data center networks is inflexible and require manual configuration by system administrators, which result in frequent misconfigurations. This paper presents a policy-aware switching layer (PLayer) in ...
