Current network infrastructures exhibit poor power efficiency, running network devices at full capacity all the time regardless of the traffic demand and distribution over the network. Most research on router power management are at component level or link level, treating routers as isolated devices. A complementary approach is to facilitate power management at network level by routing traffic through...
Multi-protocol label switching (MPLS) is a promising cutting-edge technology for advanced forwarding of IP packets. Better performance of multicast routing in large-scale networks is expected when it is implemented over MPLS. In this paper, we simulate core-based tree (CBT) multicast routing protocol over MPLS-based networks using NS2, and compare its performance with protocol-independent multicast-sparse...
A new breed of network intensive "e-science" applications are emerging that require a new perspective on how networks provide resources to the user. These e-science applications often have large raw capacity requirements (tens of gigabits/second) and require global reach. The discipline scientists expect this type of performance to be deterministic and repeatable, and available in conjunction...
