Data Sheet

Zarlink Semiconductor Inc.
We assume that the network manager knows his applications, such as voice, file transfer, or web browsing, and
their relative importance. The manager can then subdivide the applications into classes and set up a service
contract with each. The contract may consist of bandwidth or latency assurances per class. Sometimes it may
even reflect an estimate of the traffic mix offered to the switch, though this is not required.
The table below shows examples of QoS applications with eight transmission priorities, including best effort
traffic for which we provide no bandwidth or latency assurances.
In our model, it is possible that a class of traffic may attempt to monopolize system resources by sending data at a
rate in excess of the contractually assured bandwidth for that class. A well-behaved class offers traffic at a rate no
greater than the agreed-upon rate. By contrast, a misbehaving class offers traffic that exceeds the agreed-upon
rate. A misbehaving class is formed from an aggregation of misbehaving microflows. To achieve high link utilization,
a misbehaving class is allowed to use any idle bandwidth. However, the quality of service (QoS) received by
well-behaved classes must never suffer.
As Table 1 illustrates, each traffic class may have its own distinct properties and applications. As shown,
classes may receive bandwidth assurances or latency bounds. In the example, P7, the highest transmission
class, requires that all frames be transmitted within 0.2 ms, and receives 30% of the 1 Gbps of bandwidth at that
port.
Best-effort (P1-P0) traffic forms a lower tier of service that only receives bandwidth when none of the other
classes have any traffic to offer.
In addition, each transmission class has two subclasses, high-drop and low-drop. Well-behaved users should
not lose packets. But poorly behaved users – users who send data at too high a rate – will encounter frame
