Abstract: A method for three dimensional wireless network monitoring that includes receiving endpoint device data at one or more access points and receiving wireless coverage data at the one or more access points. The method further includes transmitting the endpoint device data to a client device, wherein, when the endpoint device data is received by the client device, causes the client device to display an endpoint device indicator in a three dimensional graphic visualization using a first set of visual characteristics determined based on the endpoint device data; and transmitting the wireless coverage data to the client device, wherein, when the wireless coverage data is received by the client device, causes the client device to display a wireless coverage indicator in the three dimensional graphic visualization using a second set of visual characteristics determined based on the wireless coverage data.

Abstract: Methods and apparatus for preventing an IP address from being assigned to a client implementing a protocol such as DHCP are disclosed. This is particularly useful in an environment such as a Mobile IP environment in which a network device (e.g., Access Point) performs proxy registration on behalf of the client. When the client transmits a detection packet to detect whether its IP address is still valid (e.g., whether it is on the same sub-network on which the IP address was allocated), a response is transmitted to the client that indicates that the client is still on its home network. This response is transmitted regardless of whether the client is still on its home network. Since the client believes it is still on its home network, a new IP address will not be assigned to the client. As a result, an existing Mobile IP session will not be interrupted.

Abstract: Methods and apparatus for implementing proxy Mobile IP in a system implementing multiple VLANs are disclosed. Specifically, a network device such as an Access Point or Foreign Agent supports multiple VLANs on a plurality of interfaces. In addition, the network device implements proxy Mobile IP on at least one interface. The network device ascertains a subnet map of a node, where the subnet map corresponds to a VLAN. It then identifies a Home Agent associated with the subnet map or VLAN via which to register the node. The network device then composes a registration request on behalf of the node, where the registration request identifies the node (e.g., IP address) and includes a Home Agent address associated with the Home Agent. The registration request also directly or indirectly indicates the interface corresponding to the VLAN via which data packets are to be routed. The registration request is then sent on behalf of the node.
