Network switching method and apparatus, wireless access apparatus, and wireless network

Abstract

In a wireless network, access points communicate with each other by transmitting and receiving data in first units and with client devices by transmitting and receiving data in second units over wireless links. A first unit encapsulates one or more second units addressed to client devices served by the same access point. Multiple second units encapsulated in a single first unit are transmitted with a single first-unit header. This scheme enables more payload data to be delivered with less overhead than would be required if every second unit were to be encapsulated in a separate first unit.

Description

technical field [0001] The present invention relates to a network switching device and method, a wireless access device and a wireless network, for example, a switching device that can be used to transmit and receive communication signals in a wireless network, a wireless access device with the switching device, and a wireless access device with A wireless network composed of devices. Background technique [0002] For example, in a wireless network, access control between wireless network devices is performed by a wireless access device (access point device). In general, an access point device exists on a wired network and has a configuration that can be connected to an external network or other access point devices. For this reason, for example, access point devices cannot be installed in places where wired lines cannot be laid, and there is a problem that it is impossible to construct a wireless network that can be connected to an external network. [0003] In order to s...

For this reason, especially in the case of communication in which short frames are sent frequently, such as VoIP (VoiceOver IP) communication, it is necessary to set IFS and compensate the waiting time for each frame, so the overhead increases
