摘要:
Mobile nodes support simultaneous OFDM links with multiple points of network attachment. A MN may simultaneously use multiple IP addresses, allowing packets addressed to the mobile to be routed over different paths. Alternatively, the MN may have a single IP address with packets corresponding to different applications, e.g., identified by packet header information, being routed over different paths. Thus packets corresponding to one application, e.g., a voice application, may be routed over one wireless link while packets corresponding to another application, e.g., a data application such as E-mail, may be routed over another wireless link, while packets corresponding to still another application, e.g., a broadcast TV service may be communicated over another wireless link. The direction of communication, latency, reliability and other QoS characteristics of the different wireless links may be considered in path selection to provide MN's user with cost effective service while still meeting minimum application requirements.
