During the last few years the Internet has grown tremendously and has penetrated all aspects of everyday life. The network services can be classified according to their level of QoS constrains, which describes how tightly the service can be bound by specific bandwidth, delay, jitter, and loss characteristics. At the first sight, three basic levels of end to end QoS can be provided across a heterogeneous network: The best-effort service, differentiated service (also called soft QoS), and guaranteed service (also called hard QoS), where an absolute reservation of network resources for specific traffic is provided through bandwidth reservation mechanisms. Quality of Service (QoS) by managing the delay, delay variation (jitter), bandwidth, and packet loss parameters on a network becomes the secret to a successful end-to-end business solution. It is the set of techniques to manage network resources.
Distribution applications such as video conferencing, distributed interactive simulations (DIS), Grid computing, storage area network (SAN), Distributed content distribution network (CDN) etc needs to transfer huge amount of data from a source to multiple number of designation. These types of data requires large amount of bandwidth, which is overcome with manycasting. The QoS constraints such as Physical layer impairments, delay, reliability, fault tolerance, data access latency, jitter etc., Optical Burst Switched (OBS) network is used to solve some of the QoS constraints to an extend such as delay, more bandwidth utilization than OCS network and Remove throughput limitation and Reduce processing requirements than OPS network. This paper deals with the detailed review of QoS, Manycasting and OBS network.
