the container which is intermittently replenished by tokens according to incoming frames and is continu-

ously emptied. Regulatory measures are implemented at a certain height to ensure the bucket does

not overflow.

PIRL - Edit section of this menu is made up of several groups of parameters:

• Resource identification.

• Resource capacity, transfer byte into tokens.

• Method of counting frames.

• Regulatory interventions (drop frame - reduce feeding)

• Selecting frames (all - by priority QPri - by type).

The above mentioned parameters are used to allocate part of a frame to each Resource. Their passage

is regulated thus avoiding network congestion. If there is a framework that does not match the filter of

any Resource, this then passes to the switch without restrictions.

Switching block

In this block (L2-switch) each frame is routed to a designated port according to the Advanced menu.

Egress queue

Block output queues. Each port receives frames from the L2 switch through 4 queues (No. 3-0). The

highest priority has a queue No. 3. The frames are organized into queues according to their priorities

QPri.

The Method to empty queues is selected by the parameter Scheduling Mode. The emptying rate is

governed by the Rate limit parameter.

A Frame sent from the port to the network can be identified by priority FPri, although it is also possible

to change its tag: see menu VLAN - Egress mode.
