Patent ID: 7778270

Claim:
A network comprising: a node capable of communicating with other nodes, the node comprising: a receiver; and a physical layer sub-module connected with the receiver, the physical layer sub-module comprising: a modulation processing module; and a code-switching assignment element, the code-switching assignment element having orthogonal codes, wherein the orthogonal codes are selected from a group consisting of: gold codes and low density parity check codes; and wherein the physical layer sub-module receives a signal encoded in a first orthogonal code from another node for routing the signal at a physical layer in accordance with a second orthogonal code as provided by the code-switching assignment element; and wherein the physical layer sub-module detects the signal at a physical layer of a second node having a second orthogonal code decoder as noise; and wherein the node immediately transmits the signal encoded in the second orthogonal code after detecting the signal encoded in the first orthogonal code, such that the signal is not received and decoded, in its entirety, at a network layer of an intermediate node in the network prior to beginning routing of the signal encoded in the second orthogonal code.
