¿µ¹®³»¿ë¿ä¾à | Mobile IP is intended to enable nodes to move from one IP subnet to another. This makes mobile IP suitable for mobility across heterogeneous media. From the network provider's point of view, future networks are designed to support network operation and maintenance by guaranteeing acceptable quality of service (QoS) levels and satisfying various service level agreements (SLAs) negotiated with customers. To support future business models, the mobile IP network has to be upgraded to meet the demands placed by real-time and multimedia applications. It then provides various features such as fault tolerance, traffic prioritization, and QoS classes. In the MPLS network, once a packet is classified according to quality of service, no further header analysis is done by subsequent routers: all forwarding is driven by the labels. The MPLS network can provide the QoS-enabled and reliable tunnels for mobile IP service for the various sets of service requirements. This standard covers service requirements and definitions, service architecture and application procedures to support the mobile IP services over MPLS. | ||
