Overview of Priority Re-marking

Overview of Priority Re-marking

Modular QoS Command-Line Interface (MQC) is used to implement priority re-marking.

The priority determines the packet scheduling or forwarding sequence. Packets of different types are scheduled or forwarded based on priorities.

Priority re-marking technology increases or reduces the priority to change packet transmission. For example, priority re-marking technology re-marks 802.1p priorities in VLAN packets so that the device schedules or forwards VLAN packets based on the re-marked 802.1p priorities. This changes transmission of VLAN packets on the Layer 2 network.

This document describes how to use MQC to implement priority re-marking. Priority re-marking allows the device to re-mark priorities of packets matching traffic classification rules. The packets that require a short delay and high service quality can be re-marked with a high priority so that the packets can be preferentially scheduled or forwarded. Similarly, the priority of packets that have no special requirements on the delay or service quality can be reduced so that the device provides sufficient network resources for high-priority packets.
