In addition to the QoS appliances we tested, other vendors also are producing QoS-aware equipment.

Procera Networks MLS
Procera's MLS is a 24-port, multilayer switch with Routing Information Protocol and Open Shortest Path First routing capabilities. In addition to wire-speed routing and switching, a network administrator can prioritize traffic based on user-defined policies. Up to 100 policies can be created using a Web-based graphical user interface and can be applied per port or to all ports. Each policy is based on a set of actions that apply to each packet, which include "discard," "do not drop," "mirror" and "prioritize." Actions can be based on IP port number, IP address or subnet. Additional QoS features are being planned.

U4EA FlowFusion
U4EA's FlowFusion device also can control WAN bandwidth. It consists of two 10/100M bit/sec ports (one for inbound, one for outbound) and usually is inserted between a LAN switch (the branch office) and the upstream WAN router.
U4EA is promoting FlowFusion specifically for use in videoconferencing and voice over IP, but it can be used with any IP-based application.
