Creating and Editing an ATM Data Stream

An ATM Protocol Data Unit (PDU) comprises the unsegmented components of ATM data:
•
The ATM Header
•
An AAL5 trailer
•
An optional LLC/SNAP header
•
An IP packet payload
Creation:
To create an ATM stream:
1. On the Simulation menu, click Data Streams....
The Data Streams dialog box appears.
2. Click Create Stream....
The Create Steam dialog box appears.
3. Type the name of the ATM stream in the Stream name box.
4. Select ATM from the Stream type list.
5. Click Continue.
The ATM Stream dialog box appears.
To create a PDU:
1. Click Create PDU(s).
The Create AAL5 PDU dialog box appears.
2. Type the values you want for the ATM header.
This header is prepended to each segmented ATM cell. If you select Automatic for PTI, then
the box will contain zero for all cells except for the last one, in which the box will contain a
one.
3. For RFC1483 options, you can select LLC/SNAP, which prepends a header to the packet
data, or VCMUX, which does not prepend a header. The optional header plus the packet data
constitute a CS-DSU information box. Currently, an AAL5 trailer is always appended to the
CS-DSU information box.
4. If you want to encapsulate a single IP packet, click the Single Packet option.
— Click IP Header to specify the fields of the IP header (see
— Click Data Payload to specify the data payload for the IP packet (see
5. If you want to encapsulate a pool of packets, click the Multiple packets from pool option.
Select a packet pool from the list of available pools.
6. To import a previously created packet pool, click Import Pool.
7. To create a new pool, click Create Pool.
