Popa et al (2010) CloudPolice: Taking Access Control out of the Network (HotNets)

October 7, 2010 paper

In a virtualized cloud environment, instead of enforcing access control inside the network using middleboxes, this paper advocates to put the access control inside the physical servers. [more]

Sun & Wang (2010) Enable Cache Effect on Forwarding Table in Metro-Ethernet (ACN)

October 7, 2010 paper

Imagine a Metro-Ethernet, if ARP is allowed to broadcast, the broadcast storm would be tremendous. In this paper, it assumes that the consumer edge (CE) and provider edge (PE) switches have a cache for the forwarding table. The cache is to remember the IP-MAC address association it ever encountered (e.g.... [more]

Avin et al (2009) From Trees to DAGs: Improving the Performance of Bridged Ethernet Networks (GlobeCom)

October 6, 2010 paper

This paper avocates an alternative to spanning tree protocol for Ethernet. Instead of building a tree (which is a undirected graph), it builds a directed acyclic graph (DAG) out of the network. The benefit of this is that, (1) have a better utilization of network links; (2) does not use... [more]

Kim et al (2009) Revisiting Route Caching: The World Should Be Flat (PAM)

October 6, 2010 paper

This paper measures the effectiveness of caching in routing in Tier-1 ISP. [more]

Edwards et al (2009) Diverter: A New Approach to Networking Within Virtualized Infrastructures (WREN)

October 6, 2010 paper

This discuss the networking issue of having virtual machines in a cluster environment. The point is to make all VMs looks like and operates like a real machine in a network. However, as a virtualized environment, different VMs may arbitrarily hosted by a physical machine. Therefore, the routing rules, firewall,... [more]
