Abstract(in English) For solving problems of TCP in a long-fat network, a transport-layer protocol called XCP (eXplicit Control Protocol) has been proposed. XCP aims at realizing efficient congestion control by sending explicit feedback information from a router to source hosts. In the literature, there have been several simulation experiments for evaluating performance of XCP. However, stability of XCP in a general network has not been analyzed. In this paper, we therefore analyze stability of XCP in a network with multiple XCP flows with different propagation delays. Through several numerical examples, we show the following things. (1) When propagation delays of XCP flows are different, XCP operates more stably rather than when propagation delays of all XCP flows are identical. (2) When variation of propagation delays of XCP flows is large, XCP operates unstably. (3) Stability of XCP is not affected by the bandwidth of XCP router's output link.
