ABSTRACT:
Methods, apparatuses and systems directed to partitioning access points into two or more network access layers, such as overlay and underlay network access layers. According to one implementation of the present invention, a wireless network management system partitions a set of wireless access points into an overlay network for low-functionality clients and an underlay network for high-functionality clients. As described in further detail below, each of the overlay and underlay networks provides a class of network service, where each class of network service differs relative to at least one attribute (e.g., type of 802.11 access, data rates, High-Density, Quality-of-Service, encryption, compression, etc.). For didactic purposes, the overlay network is also referred to as the overlay network service layer (NSL) and the underlay network is referred to as the underlay NSL. In one implementation of the present invention, a partitioning algorithm is used to partition wireless access points into overlay and underlay networks. As described in further detail below, the partitioning algorithm, in one implementation, automatically assigns access points to the overlay and underlay networks based on the coverage needs of each network and the coverage parameters of each access point. In one implementation, the partitioning algorithm can be configured such that the overlay network provides maximum coverage for low-functionality clients, and the underlay network enables maximum performance for high-functionality clients.
