A technology for multicasting packetized multimedia streams such as IPTV over the Internet backbone is proposed and explored through extensive simulations. An RSVP or DiffServ algorithm is used to reserve resources (i.e., bandwidth and buffer space) in each packet-switched IP router in an IP multicast tree. Each IP router uses an Input-Queued (IQ) switch architecture with unity speedup. A recently...
Telerobotic control systems can tolerate a fixed delay in the control loop, but are highly sensitive to delay jitter. Before such systems can be widely deployed over the Internet, packet switching techniques which ensure a high 'Quality of Service' (QoS) and low delay jitter will be required. It is shown that guaranteed-rate traffic flows can be delivered over the Internet backbone with very low delay...
