Weighted fair queuing, however, has many advantages over priority queuing and custom queuing. Priority queuing and custom queuing require the installation of access lists; the bandwidth has to be pre-allocated and priorities have to be predefined. This is clearly a burden. Sometimes, network administrators cannot identify and prioritize network traffic in real time. Weighted fair queuing sorts among individual traffic streams without the administrative burden associated with the other two types of queuing.
Figure 2-14 illustrates an example of this operation. Figure 2-14: Sample DECnet ATG implementation. 4 and is a Level 1 router. 5 and is an area router. At this point, no routing information is exchanged between the two networks. The router maintains a separate routing table for each network.
Assume that you decide to implement integrated IS-IS instead of IGRP. In doing this, you gain a measure of interoperability; however, you lose some functionality. For instance, you cannot load balance traffic over unequal parallel paths. Similarly, some modems provide a high level of proprietary diagnostic capabilities, but require that all modems throughout a network be of the same vendor type to fully exploit proprietary diagnostics. Previous internetworking (and networking) investments and expectations for future requirements have considerable influence over your choice of implementations.
