摘要： One embodiment of the invention includes a method of managing network communications in a network device. The network device includes software components and modules. Some of the components control the interaction between modules, while other components perform specific functions for associated modules. A module manager component controls the creation and destruction of modules as well as their interactions. A communications manager component manages network communications in the network device. The network communications is supported by creating a number of modules that are associated with components that implement different parts of a network protocol. As a result of the use of the modules, a component need not know which other component(s) it depends upon, nor need it know which other component(s) depend upon it. This allows components to be used together very easily in many different configurations. The modules also allow the same component to be used by multiple modules.

摘要： A system and method for a hierarchical distributed control architecture to support roaming wireless client devices. Access switches serve one or more Internet Protocol (IP) subnets that include plural IP addresses. The access switches are arranged in switch peer groups and store information about other access switches in that switch peer group and about locations of wireless client devices that are associated with any access switch in the switch peer group. The access switches are further grouped into a corresponding mobility sub-domain each including plural switch peer groups. Plural controller devices control access switches in a corresponding mobility sub-domain. Each controller device stores information about the access switches and about locations of wireless client devices within its mobility sub-domain. A central controller device communicates with the controller devices for the respective mobility sub-domains. The central controller device stores information about locations of wireless client devices in the mobility sub-domains.

摘要： A reverse address resolution protocol for use in a communication network which allows resolution logic to provide a higher level protocol information (such as an IP address) to a source of a request for such information, independent of the physical network address of such source. The protocol is used in a processor having a plurality of ports, at least one of such ports connected by a point-to-point channel to a remote network device. Reverse address resolution protocol is responsive to a resolution request from the remote network device across the point-to-point channel to supply the higher level protocol information based upon the port through which the resolution request is received, rather than the physical network address of the requesting device. Thus, a remote device may be coupled to a network, and connected to a central management site across a point-to-point communication link, in a "plug and play" mode. The person connecting the device to the remote network does not need to determine the physical network address of the device or configure the device with a higher level address protocol.
