Class of Service

Class of Service support allows you to assign a higher priority to selecte d
traffic passing through the switch. The ELS100-24TXM switch supports
Class of Service attributes per the IEEE 802.1p draft standard using a
priority queuing mechanism. This feature ensures that traffic during
congestion periods will not interfere with traffic assigned a higher priority.
Traffic assigned a lower priority is subject to discard when memory is in
short supply. See Appendix E, “Class of Service,” for more information.
Application Examples
The exploding popularity of the Internet and of corporate intranets, as well
as new, high-bandwidth desktop applications, are driving the demand for
Fast Ethernet. The increase in multimedia traffic and the need to supp ort
legacy protocols alongside new, data intensive applications is driving the
need for network segmentation and traffic prioritization.
The ELS100-24TXM switch is ideal for meeting the needs of today’s high
performance networks. The switch’s low cost and high port count makes
it attractive and affordable for dedicated 10/100Mbps connections to the
desktop. In addition, extensive features, including redundant links, traffic
Class of Service and VLAN capability, provide the management needed
for the workgroup and local backbone.
