A dynamic routing control system for high-performance PC cluster with multi-path Ethernet connection

VLAN-based Flexible, Reliable and Expandable Commodity Network (VFREC-Net) is a network construction technology for PC clusters that allows multi-path network routing to be configured using inexpensive Layer-2 Ethernet switches based on tagged-VLAN technology. Current VFREC-Net system encounters problems with traffic balancing when the communication pattern of the application does not fit the network topology, due to its static routing scheme.
