To achieve peak network performance, the routing of traffic and use of available bandwidth is configurable. The information used in configuring traffic routing and bandwidth is gathered from historical network trends. The tasks required to optimize the network are: specifying channel utilization, specifying the class of service, and managing bandwidth. These tasks are discussed in the paragraphs that follow.
Use the cnfchutl command to specify the expected utilization of Frame Relay, data, or voice channel as a percentage of the channel's total capacity. The specified value can be in the range of 0% to 100%. 100% is the default for data and Frame Relay channels. The default for voice channels is 40%. To display the utilization of a particular trunk, use the dsptrkutl command. This command displays a details on the packets transmitted over the trunk. The user can specify the rate in seconds at which the screen is updated. Use the dspload command to display the load for a specified trunk at a node.
Use the cnfcos command to specify a class of service (COS) for a Frame Relay, data, or voice channel. The class of service is the delay in seconds before the network reroutes a connection in the event of a trunk failure. The range is 0-15. By spreading out the COS numbers to vary the rerouting delay, one class of channels has a chance to reroute before the another class starts to reroute.
There are a number of commands that assist in managing bandwidth to achieve satisfactory traffic patterns.
upcon, dncon | The up and down connection commands can be used to temporarily down connections of a specified COS, thus releasing bandwidth for other services. Often it is possible to down some voice connections to provide more bandwidth for data and Frame Relay connections. |
cnfpref | The configure preference command can be used to specify preferred routing for intra-domain connections. This command can be used to assist in balancing the load on the network's trunks. |
dsprts, prtrts | The display and print routes commands can be used in conjunction with the cnfpref command to display the current connection routing information. |
Table 10-1 shows the full command name and starting page for each description.

Informs the system software of the expected utilization rate of connections with traffic-dependent compression algorithms (voice connections with VAD, data connections with DFM, Frame Relay connections, FastPAD voice connections with ATC-8K, ATC-12K, ATC-16K, or CELP-8K compression). The software load model then takes the user-specified rate of the connection and modifies it by using the percent of utilization you specify with cnfchutl. The resulting rate is used in calculations for loading trunks. The load model uses these figures instead of calculated estimates from real traffic patterns.
On a FastPAD channel, the compression rate adapts to the congestion level within the network. The configured compression rate indicates the maximum rate for the channel. FastPAD channels detect FAX signals and adapt their rates for FAX transmittal. For the full benefits of the compression algorithms to be used, the default utilizations should be modified after traffic studies have been performed. Also, traffic studies of Frame Relay connections should be used to determine optimum utilization settings. When calculating loads in a network, the load allocated to a connection is:
For example, with a channel utilization of 50% and a full load of 480 packets per second, the load allocated to a connection is:
For data connections with DFM turned off, for voice connections with VAD turned off, and for all FastPAD data connections, the bandwidth allocated is always the maximum bandwidth for the connection type. In other words, the utilization, although configurable, is ignored for a voice channel without VAD, a data channel without DFM and all FastPAD data channels.
If you use cnfchutl to increase the utilization of a connection, the system verifies that the additional bandwidth is available on the connection's current route. If the bandwidth is not available, the system attempts to reroute the connection. If no other route is found, the connection is failed.
If you use cnfchutl to decrease the utilization of a connection, the system makes the bandwidth available to other connections that require a route. The screen displayed by the cnfchutl command depends upon whether a data channel, voice channel, or Frame Relay channel is specified.

Determines the priority for rerouting a connection. You determine the priority by specifying a delay before the network reroutes one or more failed connections. The COS applies to:
When connections have failed (typically due to a trunk failure), the network reroutes them according to priorities that are set primarily by the class of service (COS). The value of COS is the number of seconds the network waits before it begins to reroute the connection, so the COS determines the rerouting order for connections owned by a node. The range of possible COS values is 0-15.
The number of connections in a network has an effect on the increment between COS values you should use. For larger numbers of connections, you should allow more time to reroute the connections in a class. To facilitate the greater time required to reroute larger numbers of connections, use a larger increment between COS values. In a larger network, for example, you could specify COS values that are 3 seconds apart (such as 0, 3, 6, 9, 12, and so on, for example). For a network with less traffic, assign COS values in increments of 1 or 2. This strategy ensures that all connections of a given COS reroute before the connections with the next COS start to reroute.

route | Designates the preferred route for the connection(s) to take through the network. The route is designated by one or more "trunk/node name" pairs. At a given node alpha, for example, entering a route of "12/delta 6/epsilon", would route the connection from alpha to delta via delta's trunk 12. The connection would then go from delta to epsilon via epsilon's trunk 6. A "+" causes the connection's current route to become the preferred route.

Deactivates (downs) a connection, bundle of connections, a connection group or all connection in a COS or COS range. The dncon command temporarily removes one or more connections from the network. This command is useful for temporarily removing voice connections when additional bandwidth is necessary for other types of connections.
Connections can be downed immediately or with courtesy. Even with immediate downing, a prompt appears that requests confirmation. With courtesy downing, the system waits until the connection is onhook before downing the connection. Courtesy downing is possible only if the onhook status has been configured with the cnfvchtp command. Courtesy downing is not available for FastPAD connections because the signaling information between the end points is not visible to the IPX or IGX node. The upcon command reactivates the voice connections. The up/down status of the voice connections appears in the "State" column of the dspcons screen. Table 10-7 shows each item in the State column.

Displays both the used and available bandwidth (both in the transmit and receive directions) for each trunk at the specified node. The "transmit" direction is from the node specified and to the node at the other end of the trunk. In the screen display, the numbers of disabled trunks appear in dim, reverse video on the screen.
The dspload display reflects the static load model stored by the node and used to determine the bandwidth available for new connections and reroutes. The display does not represent changes due to the dynamic utilization of the trunks. Some types of connections, such as voice connections using adaptive voice and data connections using Data Frame Multiplexing (DFM), suppress packets. In contrast, Frame Relay connections may generate additional packets when bandwidth permits.
When this command is executed at a local node in structured networks, the information displayed is for any node on the intra-domain lines belonging to the same domain. When this command is executed at a junction node, the information displayed is for all inter-domain lines between all junction nodes. The node uses the terminating and through routed connections' calculated load to calculate the trunk load. The connection type (v, c, a, or d) or baud rate (9.6 Kbps, 56 56 Kbps, and so on) and other factors determine its basic load. The calculated trunk load is also modified by the cnfchutl command for connections that use VAD, DFM, or Frame Relay.
A certain amount of bandwidth is reserved for each trunk (using cnftrk). The reserved bandwidth is available only for high priority packets (e.g. PCC traffic). The node cannot route connections using this reserved bandwidth. The following loading, in packets per second, is calculated for each trunk in each direction:
If the dspload arguments include a trunk number, detailed information for each of the packet types on that line appears. See Example 2. Additional categories of information for Frame Relay loads on the trunk include Cmax In Use, Cmax Available, and Cmax Capacity.
