“…The multicast technology is also applicable to other multimedia streams over the Internet, including VOIP, Video-on-Demand, Telemedicine, and Telerobotic control over IP. The application of the technology to deliver telerobotic control systems over saturated Internet backbone networks is described in [35].…”

The design of an IPTV multicast system for the Internet backbone network is presented and explored through extensive simulations. In the proposed system, a resource reservation algorithm such as RSVP, IntServ, or DiffServ is used to reserve resources (i.e., bandwidth and buffer space) in each router in an IP multicast tree. Each router uses an Input-Queued, Output-Queued, or Crosspoint-Queued switch architecture with unity speedup. A recently proposed Recursive Fair Stochastic Matrix Decomposition algorithm used to compute near-perfect transmission schedules for each IP router. The IPTV traffic is shaped at the sources using Application-Specific Token Bucker Traffic Shapers, to limit the burstiness of incoming network traffic. The IPTV traffic is shaped at the destinations using Application-Specific Playback Queues, to remove residual network jitter and reconstruct the original bursty IPTV video streams at each destination. All IPTV traffic flows are regenerated at the destinations with essentially zero delay jitter and essentially-perfect QoS. The destination nodes deliver the IPTV streams to the ultimate end users using the same IPTV multicast system over a regional Metropolitan Area Network. It is shown that all IPTV traffic is delivered with essentiallyperfect end-to-end QoS, with deterministic bounds on the maximum delay and jitter on each video frame. Detailed simulations of an IPTV distribution system, multicasting several hundred high-definition IPTV video streams over several essentially saturated IP backbone networks are presented.

“…For this to be possible, it is necessary that the information signals reach the end location with high degree of reliability and predictability. Such systems are said to have stringent real-time QoS constraints, of which if not met can lead to disaster; for example, the unbounded delay and jitter in the control system of telerobotic surgery can lead to control loop instability and mission failure (Szymanski and Gilbert, 2010). Lastly, the availability of resources is also imperative in health networks, because the generated traffic may be crucial for the patients' health and life (Zvikhachevskaya et al, 2009).…”

Abstract-Ensuring end-to-end quality-of-service for video applications requires the network to choose the most feasible path in terms of bandwidth, delay and jitter. Quality of service can only be ensured if the paths are reliable -perform to specification per request. This paper makes four contributions to research. First, it presents Reliable Video over SoftwareDefined Networking (RVSDN) which builds upon previous work of Video over Software-Defined Networking (VSDN) to address the issue of finding the most reliable path(s) through the network for video applications. Second, it presents the design and implementation of RVSDN. Third, it presents the experience of integrating RVSDN into ns-3 which is a network simulator used by the research community to simulate and model computer networks. Finally, it presents the results of RVSDN in terms of the number of requests serviced by the network architecture. RVSDN is able to service 31 times more requests than VSDN and MPLS explicit routing when the reliability constraint is 0.995 or greater using aggregation of reliability across network paths.
