摘要： 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.
摘要翻译：提供一种准入方案，用于从具有数据和语音分组的通信网络选择性地接收语音数据分组到语音网络。该方案可以使用诸如网络交换机的设备来实现。根据接收方案，设备的MAC地址在设备允许到语音网络时获取并存储。在数据包从通信网络进入语音网络之前，检查数据包的源MAC地址。仅当MAC地址已经被注册到语音网络时，才将数据包进入语音网络。
