|
||
|
|
<p>Network nodes maintain information about all network nodes and links between
|
||
|
|
network nodes. When a session is requested, a mode is specified. Each node
|
||
|
|
contains a class of service (COS) parameter that specifies the class of service
|
||
|
|
description that will be used to calculate the route the session will take.
|
||
|
|
The class of service also specifies the transmission priority that will govern
|
||
|
|
the rate of data transfer after the session has been established.</p>
|
||
|
|
<p>The following class-of-service descriptions are shipped with the iSeries system:</p>
|
||
|
|
<ul>
|
||
|
|
<li>#CONNECT: the default class of service</li>
|
||
|
|
<li>#BATCH: a class of service that is tailored for batch communications</li>
|
||
|
|
<li>#BATCHSC: is the same as #BATCH except that a data link security level
|
||
|
|
of at least *PKTSWTNWK is required</li>
|
||
|
|
<li>#INTER: a class of service that is tailored for interactive communications</li>
|
||
|
|
<li>#INTERSC: is the same as #INTER except that a data link security level
|
||
|
|
of at least *PKTSWTNWK is required</li></ul>
|
||
|
|
<p>If you need to force a particular route to be selected, a user class of
|
||
|
|
service (COSD) can be created. See <a href="rzahjcospi.htm#rzahjcos-pi">Create a class-of-service description</a> for a thorough
|
||
|
|
explanation.</p>
