Nowadays, the internet is used various functions such as Radio, Television, and Telephone. Forappropriate usage, we need network solutions that aim to provide end-users with Quality of Service(QoS) support. The networking research community proposed distinct QoS aware architectures andspecific traffic control mechanisms that provide distinct service levels to networkedapplications(Wang,2001).Accordingly, Internet Service Providers (ISPs) must have Service Level Agreements (SLAs) (Liu et al,2005) with their clients and with other ISPs. If neglected, must pay financial penalties. To achieve that,administrators must do some important configuration in their networks to assure that correct resourceprovisioning is achieved in the ISP domain. For example, these configurations may vary based on ISPsbecause The QoS solutions are different. Also it may includes distinct tasks such as, specifying theforwarding treatment given at each network nodes (e.g. the per-hop-behaviors(Davie et al, 2002)(Wroclawski et al,1999) of DiffServ (Blake,1998) ). defining traffic classification and packet markingrules at network edges, configuring admission control based mechanisms(Tsuchiya,2003), configuringrouting algorithms(Slattery et al,2008) or finer-grain QoS solutions, enabling signaling protocols allowper flow resource reservation(Zhang et al,1997). In addition, there is more than one solution to achieveQoS aware network infrastructure. In general, any solutions require number of components workingtogether.
