摘要:
This invention provides a structure of load-balancing packet switches with minimum buffers complexity and its concomitant methodology. It abandons the VOQ between the first stage and the second stage fabrics, which has no problems of queue delay and packets out-of-sequence. Therefore, this invention solves the packets out-of-sequence problem in load-balancing Birkhoff-von Neumann switching structure and improves the end-to-end throughput. Moreover, it greatly reduces the buffer complexity to O(N).

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.
