Abstract

In this paper we propose cmpTCP-Westwood (cmpTCPW), which is an extension of a variant of TCP-Westwood and SCTP. The proposed cmpTCPW has been implemented by altering and extending library-based open-source implementation of SCTP. The proposed cmpTCPW manages transmission control parameters of all paths simultaneously; a scheduler concurrently dispatches packets over all the paths from a common transmission queue. However, one virtual retransmission queue is maintained for each path, and the receiver sends acknowledgment for a packet on the same path on which the packet is received. In this paper we describe the proposed architecture and implementation; also, we report empirical evaluations of cmpTCPW. In our network emulation laboratory, two host computers were connected through two independent network emulators. Each network emulator runs on a separate computer, and the network parameters are adjusted independently. Our extensive evaluation shows that cmpTCPW delivers higher throughput than cmpTCP.
