Manufacturer’s Description

The BayStack Business Policy Switch (BPS) is a 24-port, stackable 10/100 Mbps Ethernet Layer 2 switch that delivers Layer 2/3/4 packet classification and prioritization to the desktop. With Web-based management and advanced IP QoS, this LAN switch is targeted for resource-intensive and delay-intolerant applications in mid- to large-sized enterprises, such as voice over IP, video streaming, and e-commerce.

While traffic policing is needed to provide different levels of service to data streams on the ingress ports, traffic shaping is needed to smooth the traffic on the uplink connection from the Business Policy Switch to the network core, yielding the most efficient bandwidth utilization. The primary customers for rate shaping are service providers or carrier customers that are selling Ethernet in place of the traditional Frame Relay, ISDN, or ATM WAN access solutions, providing end-to-end Ethernet service for simplicity. Some enterprise customers use traffic shaping as a mechanism to limit bandwidth without having to swap out physical interfaces, leaving them room to grow.

Management Remote Management Protocol: RMON QoS & Policy Management:QoS provides the ability to read, alter, prioritize and tag or mark IP traffic based upon information imbedded in Type of Service (ToS). Based on the IETF Committee's industry standards, the Business Policy Switch provides the ability to prioritize traffic based upon the required level of service for a given transaction. This level of service can be marked in the embedded information inside each IP packet's ToS field. DiffServ is based upon ToS field. The Business Policy Switch has application specific integrated circuits (ASICs) to enable DiffServ Code points can be mapped to 802.1p.The QoS policies can be configured via the Business Policy Switch built-in Web-based Management tools to facilitate QoS; or alternatively, Optivity Policy Services can be utilized for dynamic endto-end enterprise-wide policy and QoS management, which is facilitated through the Common Open Policy Service (COPS) protocol. Web-based management:Web-based management supports a Business Policy Switch only stack or a mixed stack of Business Policy Switches and BayStack 450/410 Switches. This feature provides summary, configuration, fault, statistics, application, administration and support pages for entire stack. Traffic classification and prioritization can be set via the Web-based QoS Wizard and advanced configuration tool (see Figure 5). Real-time sampling provides up-to-date LED, stats info for stacked units. Web interface also allows for static configuration of numerous parameters of the device.
