The three-port Ethernet switch incorporates two 10/100 external interfaces that support quality of service (QoS) based on IEEE standards 802.1p and 802.1q.
The OpENSolO 24G system supports features ideally suited for Gigabit-to-the-desktop applications, including IEEE 802.1Q VLANs, 802.1p packet prioritization for Quality of Service, as well as Layer 3 aware multicasting, access control and priority detection for Differentiated Services (DiffServ).
The old BCP definition, RFC1638, failed to keep up with the new IEEE standards for Ethernet such as VLANs (known as 802.1Q), Layer 2 priority (known as 802.1p), and Link Aggregation (802.3ad).
Quality of Service (QoS): 802.1p priority queues/multi?layer class of service (CoS) including flow?based bandwidth control and broadcast/multicast storm control to ensure priority to network services such as VoIP, video conferencing, IPTV, and IP surveillance.
The 802.1p priority scheme enables users to define different levels of Quality of Service (QoS) according to the application requirements.
Another advancement is support of the quality-of-service (QoS) IEEE 802.1p prioritization standard.
The CPC4411 and CPC4416 offer the most complete embedded Ethernet switch feature set in the market, including 802.3AD Link Aggregation, 802.1q VLANs and 802.1p QoS/CoS.
The TMS based L64324 management software provides a full set of features, which include the simple network management protocol (SNMP), web and console management, remote monitoring (RMON), support for the spanning tree protocol, 802.1Q VLAN, and 802.1p priority queuing support.
Newer management protocols such as Cisco's CGMP and the GARP Multicast Registration Protocol (GMRP, part of the 802.1p standard) tackle this problem by restricting the propagation of multicast traffic to only those switches that have multicast subscribers attached.
When the switches receive a frame tagged with an 802.1p priority tag, they will place it into a priority queue.
