Huawei MA5680T Traffic Profile Parameters Explanation

In Huawei MA5680T OLT, Traffic Profile is used to define and control the bandwidth limits for user services. It helps operators manage upstream and downstream traffic, avoid excessive bandwidth usage, and ensure stable network performance.

The main parameters in the traffic profile include inbound, outbound, rx-cttr, and tx-cttr.

1. Inbound and Outbound

Inbound and Outbound indicate the traffic direction from the perspective of the OLT.

Parameter Description
Inbound Traffic entering the OLT. It usually refers to the upstream direction from ONU to OLT.
Outbound Traffic leaving the OLT. It usually refers to the downstream direction from OLT to ONU.

For PON networks:

Service Direction Traffic Flow Related Parameter
User Upload ONU → OLT → Uplink Inbound
User Download Uplink → OLT → ONU Outbound

2. rx-cttr and tx-cttr

CTTR refers to Committed Traffic Rate, which is used to control the traffic bandwidth.

Parameter Description
rx-cttr Receive traffic rate. It controls the bandwidth limit in the inbound direction (user upload).
tx-cttr Transmit traffic rate. It controls the bandwidth limit in the outbound direction (user download).

This means:

  • The user’s maximum upload speed is limited to 100Mbps.
  • The user’s maximum download speed is limited to 500Mbps.

3. Default Traffic Profiles on MA5680T

The MA5680T system provides several default traffic profiles for common bandwidth requirements. These templates can be directly applied to user services or modified according to actual network requirements.

Operators can check the existing traffic profiles by using the command:

The displayed information includes:

  • Traffic profile ID
  • CIR/PIR value
  • Bandwidth limitation
  • Service application status

4. Traffic Profile Application Example

The traffic profile should be configured as:

Direction Parameter Value
Upload rx-cttr 100Mbps
Download tx-cttr 500Mbps

After applying the traffic profile to the service port or GEM port, the ONU user’s bandwidth will be controlled according to the configured values.

Traffic Profiles are an important feature of MA5680T for bandwidth management. Proper configuration can help operators provide different bandwidth packages, optimize network resources, and maintain stable GPON service performance.
