Virtual Trees are source-rooted trees in ATM networks in which VCs originating at the source but going to diierent destinations can share some of the bandwidth pre-allocated to the VT, thus providing an additional multiplexing advantage over Virtual Paths. Non-ATM protocols such as MIL-STD-188-220A can also take advantage of Virtual Trees because source concatenation provides a beneet very simi...

The concept af virtual channels is extended to multiple, virtual communication systems that provide adaptability and fault tolerance in addition to being deadlock-free. A channel dependency graph is taken as the definition of what connections are possible and any routing function must use only those connections defined by it. Virtual interconnection networks allowing adaptive, deadlock-free rou...

This article study chip communication mechanisms deeply based on the NoC (Network on Chip) technology and a load equalization of virtual channel (LEVC) routing algorithm for Torus networks is proposed, which splits the physical network into virtual networks in the case of physical link load equalization. According to the predefined rules, packets use different virtual networks on their way to d...

The creation, deployment and management of network architecture is manual, ad hoc and slow to evolve to meet new service requirements resulting in costly and inflexible deployment cycles. In the Genesis Project ([email protected]), Columbia University, we envision a different paradigm where new network architectures are dynamically created and deployed in an automated fashion based on ...
