....2 shows the proposed communication architecture based on layering in the DARPA Internet protocol suite. At the network layer, we expect to have both connectionless service (IP) as well as a connection oriented service such as that provided by Co IP (Connection oriented internet protocol) Top89, LT90] McHIP (Multipoint Connection oriented High Performance Internet Protocol) MP89] or XTP [Che88] Both Co IP and McHIP support establishment of connections with specific performance requirements such as bounds on delay and required data rates. Both the protocols are still under development and ....

....ever leaving their respective workplaces. Because of its interactive nature, networked CSCW demands real time delay and bandwidth guarantees of the underlying networks. Accordingly, research is underway to develop protocols that can manage the network resources and provide performance guarantees [9, 3, 2]. At the same time, collaborative applications are being developed to exploit the new resources. While audio and video applications are becoming widely available, another essential component of collaborative work, the network equivalent of a conference room whiteboard , has been slower to evolve. ....

....that provide an application with a guaranteed share of available resources so that the application can receive (or send) data and display it in a timely fashion. A considerable amount of work is in progress in the area of providing quality of service (QOS) guarantees over high speed networks [7, 17, 22, 29]. The ongoing work mainly concentrates on the problems of bandwidth management and switch based scheduling to provide deterministic or statistical guarantees on end to end delay, throughput, and packet losses. The solutions proposed in this area are valuable in ensuring certain QOS for network ....

....the IP multicast extensions. ISI BBN Protocol Suite. ISI and BBN have collaborated to develop a suite of communication protocols that support N way video conferencing [5] The network protocol is ST II, which provides a connection oriented service that includes multicast and QoS guarantees [4]. At the transport level, NVP [7] and PVP [8] support transmission of voice and video streams respectively. The Connection Control Protocol (CCP) 22] manages connections and performs synchronization between streams. These protocols have been used successfully to support video conferencing ....

The Discrete Scaling mechanism in the Heidelberg Transport System (HeiTS) 44] uses a receiveroriented scheme for adapting to delivered bandwidth. Here, receivers open and close ST II [22] multicast 24 connections to adapt to bandwidth. The authors do not discuss adaptation algorithms or report implementation results. As described in Chapter 1, Deering first suggested that the IP Multicast be used as a layered transmission system where layers are individually mapped onto ....

While these systems have been successfully deployed and tested in limited scope, the most significant limitation of these schemes, apart from ....

....result, failures are gracefully tolerated. A common criticism of best effort networks like the Internet is that they cannot effectively support real time traffic, and instead, the prevailing wisdom holds that new mechanisms for controlling quality of service are required (e.g. RSVP [113] ST II [14], or Tenet [10] While this argument holds for for underprovisioned networks, we initially conjectured 5 and found that effective real time communication could be carried out over uncontrolled, best effort networks through application adaptation, i.e. by adapting the application to the ....
