Packets Received and Classified BEELER AAM Queuing Mechanism Packets Transmitted Out of Port Queue p TE lt ERr eL MA Saving T21s1415 Mechanism Queue full Sixth bronze packet is dropped If these queuing operations are performed on all devices in the network then the overall effect is to speed up the flow of important traffic through the entire network Also by processing the queues containing more important traffic more frequently this reduces the likelinood that the queue will fill up because the queue will be emptied quicker and therefore reduce the risk that the more important traffic will get dropped Dropping Service Levels Key Concepts 159 The action of dropping allows the device to prevent blocked traffic from flowing on the network This is achieved by discarding dropping packets that are identified via classification as traffic that should be blocked The overall set of actions that are performed as a result of a particular classification are commonly known as a service level Service levels enable a device configuration to be specified in terms of a mapping between the classification rules and the service levels This enables several classification rules to share the same service level For example a device may be configured with service levels for a Business critical traffic a Voice traffic a The CEO s traffic a Blocked traffic a All other traffic Each

27. 8 PRIORITIZING NETWORK TRAFFIC Useful Information and References User Priority Field The following section provides useful information and references when using the Prioritizing Network Traffic feature of 3Com Network Administrator The user priority field and the tagged header that it is present in allows information about the priority level of a packet to be carried with the packet as it traverses the network The field is defined with the IEEE Institute of Electrical and Electronics Engineers 802 1D standard which is available from the IEEE website http www ieee org This standard defines the use of the eight values that the field may take These definitions are shown in Table 17 Table 17 User Priority User Priority Use 1 Background 2 Spare O Default Best Effort 3 Excellent Effort 4 Controlled Load 5 Video lt 100 ms latency and jitter 6 Voice lt 10 ms latency and jitter 7 Network Control As the table shows the default value is 0 This allows some traffic to be marked as less important than normal traffic The tagged header that the user priority field relies upon can be used in any packet in place of the normal 802 1D header However the tagged header is only normally used for packets if VLANs are being used within the network This means that if VLANs are not being used then the information about the importance of traffic cannot be conveyed from a complex classification de

29. Blocking Application Traffic Blocking traffic belonging to applications is a powerful feature for preventing the use of undesired applications on your network However if the wrong application definitions are used for blocking an application this can cause severe problems on your network There are two reasons why blocking a particular application definition may cause problems on your network a The application definition may not be narrow enough to prevent accidental classification of other application traffic For example if an application runs over TCP IP then specifying a classifier rule of IP protocol 6 the protocol number of TCP in the application definition would not be narrow enough for blocking as this would also block all other TCP IP traffic When blocking an application it is important that the definition is as specific as it can be about how to identify traffic belonging to that application In the example above it would be better in this case to specify the classifier rule of TCP port 123 assuming that the application uses TCP port 123 as this would only match and so only block TCP IP traffic using port 123 rather than all TCP IP traffic a The application definition while still being narrow may include rules that will incorrectly classify other applications as belonging to the application you wish to block For example if the definition for an application A that you wish to block specifies the classi
