The care-of address of a mobile device is the network-native IP address of the device when operating in a foreign network. Home agent A home agent is a router on a mobile node’s home network which tunnels datagrams for delivery to the mobile node when it is away from home. It maintains current location (IP address) information for the mobile ...
And meanwhile, the HA gets the updated binding information so the subsequent packets will be transferred directly from the CH to the new FA. The mobile IP with route optimization sets high requirements on the CH. The CH shall have the ability to obtain the binding information, encapsulate the packets and establish the tunnel.
An IP packet has no trailer. However, an IP packet is often carried as the payload inside an Ethernet frame, which has its own header and trailer. Per the end-to-end principle , IP networks do not provide guarantees of delivery, non-duplication, or in-order delivery of packets.
IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referred to as TCP/IP. The first major ...
The packet data protocol (PDP; e.g., IP, X.25, FrameRelay) context is a data structure present on both the serving GPRS support node (SGSN) and the gateway GPRS support node (GGSN) which contains the subscriber's session information when the subscriber has an active session.
Packet switching is used in the Internet and most local area networks. The Internet is implemented by the Internet Protocol Suite using a variety of link layer technologies. For example, Ethernet and Frame Relay are common. Newer mobile phone technologies (e.g., GSM, LTE) also use packet switching. Packet switching is associated with ...
The protocols in use today in this layer for the Internet all originated in the development of TCP/IP. In the OSI model the transport layer is often referred to as Layer 4, or L4, [2] while numbered layers are not used in TCP/IP. The best-known transport protocol of the Internet protocol suite is the Transmission Control Protocol (TCP).
A multi-bearer network (MBN) is a network having the capability to carry a data packet via one of several alternative bearers.To be more precise, the term multi-bearer network should be interpreted as meaning 'multi-bearer-type network', or in other words, a network arrangement which provides multiple different bearer types for data packet delivery.
