US Patent 10182131 Method for selecting network connection concentrators

A selection method for selecting network connection concentrators for a given set of M≥1 communication paths usable by a communicating device. Each respective interface of the communicating device is connected to a respective path. The method includes the following acts: a) identifying a set (P1, P2, . . . , PN) of N≥2 concentrators situated in at least one network to which the communicating device is connected, each concentrator making it possible to aggregate connections using a plurality of paths suitable for being used by the communicating device; b) obtaining the value of at least one quality of service parameter QoS(i,j) for at least one path i, where i=1, . . . , M, and for concentrators Pj reachable from the communicating device via the path i; and c) selecting at least one concentrator from the set on the basis of the quality of service values that are obtained. The method is applicable to the multipath TCP (MPTCP) protocol.
