Description

The Agere Systems, Inc. Voice over Internet Protocol (VoIP) Phone-On-A-Chip™ solution currently implements a quality of service (QoS) strategy that uses a proprietary voice packet prioritization scheme called Ethernet Quality of Service using BlackBurst (EQuB). This scheme uses an algorithm (implemented in hardware) to ensure that voice packets transmitted from the device are given the highest priority on their collision domain.

The Phone-On-A-Chip solution will now become more standards based by implementing a QoS strategy that incorporates a software-based IEEE 802.1q tagging protocol for outgoing Ethernet frames. This QoS implementation will utilize an IEEE 802.1q protocol stack from Wind River Systems® and will be integrated into the VxWorks® board support package (BSP) for the T8302 as part of our standard software solution. Virtual local area network (VLAN) tag insertion will be supported on a per-port, per-socket, and global basis.
