We describe issues in designing rate allocation schemes in ATM-ABR networks for virtual source/virtual destination (VS/VD) switches. We propose a rate allocation scheme for VS/VD switches that uses per-VC queuing and per-VC control. We analyze the performance of this scheme, and conclude that VS/VD can help in limiting buffer requirements of switches, based on the length of their VS/VD control loops. VS/VD is especially useful in isolating terrestrial networks from the effects of long delay satellite networks by limiting the buffer requirements of the terrestrial switches.
