System and method for creating a transitive optimized flow path

摘要

Traffic paths based on common devices available in a network are optimized, controlled, manipulated and created. The new paths used to optimize are not limited to the original OSI layer and/or original networks. Thus, various kinds of users/computers/devices, working in the same or in different abstraction layer networks, are combined into one collective virtual network providing the ability to compute and utilize the best (optimal) traffic path for each flow at each given time. The traffic path can be constructed especially for each flow. All or most devices and layer networks are combined in a collective virtual network when computing and constructing an optimized path for a flow. Thus, there is no need to add additional headers to a flow thereby eliminating the addition of overhead to the flow.

1. A method for creating a transitive optimized path for a flow, comprising:
maintaining a topology database of collective virtual networks (CVNs) by collecting topology information related to three or more of different Open System Interconnection (OSI) model layers from a plurality of network devices, wherein a CVN connects devices working in networks that belong to different OSI layers; identifying a new flow establishment to be carried over a first path; identifying, based at least in part on information from the CVN database, a Transmitting Device Set with Promiscuous and Re-writing Capabilities (TDSPRC) that transfers the new flow; defining two or more coupled promiscuity networks (CPN) for carrying the new flow, wherein the traffic over the two or more CPNs passes through the TDSPRC and wherein at least one coupled network within a particular CPN differs from at least one other coupled network within any of the two or more CPN in at least one network characteristic; planning, based at least in part on information from the CVN database, an optimized path, other than the first path, for the new flow; and directing the new flow through the planned optimized path by utilizing the TDSPRC to rewrite at least one original header of a frame of the new flow.
