ATM Traffic Management

ATM Traffic Management

ATM traffic management includes ATM-Diffserv management and ATM policy management.

Creating an ATM Policy

This section describes how to create an ATM policy for an ATM connection.

Prerequisites

You are an NM user with Operator Group rights or higher.

Tools, Equipment, and Materials

U2000

Procedure

  1. In the NE Explorer, select the NE from the Object Tree and choose Configuration > Packet Configuration > QoS Management > Policy Management > ATM Policy from the Function Tree.
  2. Click New.
    The Create ATM Policy dialog box is displayed.
  3. Set ATM policy parameters according to the planning information.



  4. Click OK.

Modifying an ATM Policy

This section describes how to modify the QoS parameters of an ATM policy.

Prerequisites

You are an NM user with Operator Group rights or higher.

Tools, Equipment, and Materials

U2000

Procedure

  1. In the NE Explorer, select the NE from the Object Tree and choose Configuration > Packet Configuration > QoS Management > Policy Management > ATM Policy from the Function Tree.
  2. Click Query.



  3. Select the required ATM policy and modify its parameters according to the planning information.
  4. Click Apply.

Creating an ATM-DiffServ Domain

This section describes how to create an ATM-DiffServ domain. If the default ATM-DiffServ domain does not serve the purpose, a new ATM-DiffServ domain needs to be created.

Prerequisites

You are an NM user with Operator Group rights or higher.
Tools, Equipment, and Materials

U2000

Procedure

  1. In the NE Explorer, select the NE from the Object Tree and choose Configuration > Packet Configuration > QoS Management > Diffserv domain Management > ATM CoS Mapping Configuration from the Function Tree.
  2. Click New.
    The Create ATM CoS Mapping dialog box is displayed.
  3. Configure an ATM-DiffServ domain according to the planning information.



    NOTE:
    • For eight queues, eight PHBs are available: BE, AF1, AF2, AF3, AF4, EF, CS6, and CS7. The OptiX OSN equipment provides different QoS policies for queues of different service classes.
    • CS6 to CS7: highest service classes, mainly applicable to signaling transmission.
    • EF: fast forwarding, applicable to services of low transmission delays and low packet loss rates.
    • AF1 to AF4: assured forwarding, applicable to services that require an assured transmission rate rather than delay or jitter limits.
      NOTE:

      AF1 defines three sub-classes: AF11, AF12, and A13. Only AF11 can take effect. This rule also applies to AF2, AF3, and AF4. To be specific, only AF21, AF31, and AF41 can take effect.

    • BE: best effort, applicable to services that do not require special processing.

  4. Click OK, and close the dialog box that is displayed.

Modifying an ATM-Diffserv Domain

This section describes how to modify an ATM-DiffServ domain. By performing this operation, you can modify the mapping between ATM service categories and PHBs.

Prerequisites

You are an NM user with Operator Group rights or higher.
