Providing end-to-end QoS in Next Generation Networks (NGNs) using combined SIP HMIPv6 (CSH)

Next Generation Networks (NGNs) promise Always Best Connection in heterogeneous networks. Providing end-to-end QoS in such environment is a challenging task. Since application's requirements and user's expectations are increasing, QoS gains the significance in NGNs. In order to provide end-to-end QoS in NGNs, this paper proposes a new protocol Combined SIP HMIPv6 (CSH) with a module QoS manager. Unlike other QoS mechanisms, CSH focuses on both core and edge networks. The achievements of CSH will include better session and terminal mobility, network mobility, proper bandwidth management, good resource reservation, user authentication and less delay while establishing multimedia traffic.
