An admission scheme is provided for selective admission of voice data packets to a voice network from a communication network having data and voice packets. The scheme can be implemented using a device such as a network switch. According to the admission scheme, the MAC address of a device is acquired and stored upon admission of the device to the voice network. The source MAC address of data packets is checked before the packets are admitted from the communication network to the voice network. A packet is admitted to the voice network only if the MAC address is registered with the voice network.

Authentic device admission scheme for a secure communication network, especially a secure IP telephony network

Bandwidth is deployed within a wireless network efficiently by making multiple channels available to wireless devices within a coverage area and intelligently controlling access to those channels. For example, channels to which each wireless device is registered with may be based on quality of service factors. According to one embodiment, upon attempted access to a wireless network channel, an access point grants or refuses a wireless device access based on quality of service factors relating to the device, the channel and the other channels that the device could access.
