CODE-DIVISION-MULTIPLE-ACCESS (CDMA)-BASED NETWORK CODING FOR MASSIVE MEMORY SERVERS

摘要

Technologies are generally described for code-division-multiple-access (CDMA)-based network-coding for reading data from massive memory servers. According to some examples, data may be modulated by spreading sequences prior to being transmitted from one memory node to another. In addition, the received signals (modulated data) from multiple memory nodes may be combined by a receiver memory node before being forwarded to other memory nodes arranged in a grid of memory nodes. The memory nodes may be assigned communication bandwidths flexibly and rapidly by changing the respective spreading sequences, which may be orthogonal or near-orthogonal for different memory nodes to allow support of random-access burst or dynamic data traffic, and enhancing fault-tolerance.

1. A method for code-division-multiple-access (CDMA)-based network-coding, the method comprising:
receiving a first signal at a first memory node from a second memory node, the first signal comprising data modulated with a first spreading sequence by the second memory node; combining the first signal, at the first memory node, with a second signal received at the first memory node from a third memory node to form a combined signal, the second signal comprising data modulated with a second spreading sequence by the third memory node; and transmitting the combined signal to a fourth memory node that neighbors the first memory node.
