Embodiments of the invention relate to a self-adaptive network control transmission method and system based on TCP. By creating network coding layer between transmission layer and IP layer on both the sending and receiving nodes, we can add network-coding headers which contains specific variables in the coding packets and ACK packets, transmit and refresh those variables through network-coding packets and ACK packets, and adjust redundancy factor R according to the variables. This method can strengthen the resistance to burst loss and maintain the redundancy factor R at the optimum value, thus raise the network throughputs.

This invention provides a load-balancing structure for packet switches and its constructing method. In this method, the structure based on self-routing concentrators is divided into two stages, that is, a first stage and a second stage fabric. A virtual output group queue (VOGQ) is appended to each input group port of the first stage fabric, and a reordering buffer (RB) is configured behind each output group port of the second stage fabric. Packets stored in the VOGQ are combined into data blocks with preset length, which is divided into data slices of fixed size, finally each data slice is added an address tag and is delivered to the first stage fabric for self-routing. Once reaching the RB, data slices are recombined into data blocks. This invention solves the packet out-of-sequence problem in the load-balancing Birkhoff-von Neumann switching structure and improves the end-to-end throughput.
