Network planner

This chapter has discussed application designer, systems administrator, and channel planner functions. Creating a network assumes that there is another, higher level function of network planner whose plans are implemented by the other members of the team.

If an application is used widely, it is more economical to think in terms of local access sites for the concentration of message traffic, using wide-band links between the local access sites, as shown in Figure 18.

In this example there are two main systems and a number of satellite systems (The actual configuration would depend on business considerations.) There are two concentrator queue managers located at convenient centers. Each QM-concentrator has message channels to the local queue managers:

Figure 18. Network diagram showing QM-concentrators
The figure illustrates a network diagram showing the QM-concentrators described in the preceding text. The two QM-concentrators are connected through message channels, and each is in turn connected to three other queue managers. The entire network is therefore connected, allowing an application at any queue manager in the network to exchange messages with any other application at another queue manager in the network.
