| What are the combinatorial logic in the combined packet network? |
* Answer
| The combinatorial logic in the combined packet network means that the data packets transmitted on any non-idle edge in the set of outgoing edges O(v) of the vertex v are from all non-idle edges in the set of incoming edges I(v)A function of a packet (when v is the source node, it is its own generated packet).For example, when v has only routing function, the packet sent on its out side can be regarded as a copy of the packet received on the incoming edge.The basic idea of network coding is to perform more general local coding operations on all packets entering the node, rather than simply copying, thereby obtaining performance benefits. |
