Title: METHOD AND SYSTEM FOR DYNAMIC REGISTRATION AND CONFIGURATION PROTOCOL
Abstract:
The Dynamic Registration and Configuration Protocol (DRCP) provides a framework for registering and passing configuration information to roaming mobile hosts (105). DRCP is compatible with DHCP and can switch to using DHCP protocol if only DHCP servers (165) are present in the network (175). Most importantly, DRCP allows rapid configuration by moving address consistency checking from the critical path. Other novel features of DRCP allow: a) clients to know when to get a new address independent of the layer-2 access technology, b) efficient use of scarce wireless bandwidth, c) clients to be routers, d) dynamic addition or deletion of address pools to any DRCP node, and e) message exchange without broadcast.
