Link aggregation management system, link aggregation management device, link aggregation management method and computer-readable medium

Abstract

A first apparatus 101 and a second apparatus 102 carry out wireless data communication using a wireless transmission path that uses a plurality of physical links in parallel. In each of the apparatuses, input / output ports 111 to 113 input and output data. A plurality of wireless signal processing means 141 to 143 respectively control different ones of the physical links. The wireless signal processing means 141 to 143 respectively measure reception signal levels of the physical links, and notify a counterpart apparatus about the reception signal levels. Link aggregation control means 130 determines a priority for each of the physical links based on the signal level for each of the physical links. The packet transfer processing means 141 to 143 select, out of the physical links structuring the wireless transmission path, the physical link having a usable band of a prescribed capacity and high priority as the data recipient.

Problems solved by technology

However, because of the characteristic of the wireless transmission system, i.e., carrying out communication by causing wireless signals to propagate through the air, the wireless transmission system is susceptible to various factors in wireless transmission links, and therefore the communication quality tends to deteriorate.

Accordingly, even when the aforementioned modulation scheme or the like is used, enormous overhead is required to carry out an error correcting process using error correcting codes and the like.

Consequently, as compared to the wired transmission system via fixed cables, the wireless transmission system has a restriction in that it is difficult to widen the communication band.
