1. An adaptable virtual network system, comprising:
- a plurality of network elements, each network element communicatively coupled to at least one other network element via at least one physical link, wherein at least a portion of the plurality of network elements form an embedded system tightly coupled by shared memory and input/output resources; and
a plurality of virtual links, wherein at least one physical link comprises at least two virtual links, wherein the adaptable virtual network system supports at least two virtual networks, wherein each of the at least one physical link communicatively couples a pair of network elements, each of the at least one physical link having a physical link bandwidth based at least in part on the bandwidth of the network elements in the pair, and wherein the plurality of virtual links within each of the at least one physical link are formed by partitioning the physical link bandwidth of the at least one physical link communicatively coupling the network elements in the pair, wherein the virtual links that comprise a virtual network run the same upper-level network protocol.

12. A method of forming a virtual network in a physical network comprising network elements, the method comprising:
-
determining bandwidths between pairs of communicatively coupled network elements in an embedded system tightly coupled by shared memory and input/output resources for at least a portion of the pairs, wherein the network elements in each pair are communicatively coupled to each other by a physical link; and partitioning the bandwidths for each pair into bandwidth segments, based at least in part on a physical link bandwidth of the physical link communicatively coupling the network elements in the pair, wherein each bandwidth segment forms a virtual link between the communicatively coupled network elements in the pair, wherein the virtual links that comprise the virtual network run the same upper-level network protocol. - View Dependent Claims (13, 14, 15, 16, 17)
