A load balancing system and methodology for packet-based wireless cellular networks, whereby wireless access points are dynamically reconfigured by altering their transmission power level to modify their area of coverage. The modification function is based on the localized traffic load or congestion at each individual access point, or the collective load experienced by groups of access points. This modification to the cellular layout is used as an implicit load-balancing technique. When an overloaded access point reduces its coverage area, it forces some wireless client devices that were earlier within its footprint, but no longer within its coverage area, to attach to alternative access points. Similarly, when an underloaded access point increases its coverage area, it provides an opportunity to wireless devices, which were earlier outside its footprint, but now within the expanded coverage area, to switch attachment to this access point. By changing the access point to which a wireless device attaches, the load-levels on the individual access points are indirectly changed.

A LAN switch is one component of a communications network system composed of a virtual LAN having network terminals such as personal computers connected with ports respectively. The LAN switch provides a host table for holding correspondence between each port and address information of the network terminal connected to each port and an authentication table for holding information for authenticating a user of each network terminal. If a request takes place of changing the correspondence about the source network terminal held in the host table when relaying the packets, the LAN switch prompts a user name and a password for the source network terminal, does user authentication on the basis of the information held in an authentication table, and enables rewrite of the host table and relay of the packets if the user is correct. These processes are executed for easily preventing false use of an address or tapping or false access by a malignant user as well as analyzing or recovering the erroneously set address.
