Overview of Bandwidth Management

Overview of Bandwidth Management

This section provides the definition of bandwidth management and describes its purpose.


Bandwidth management technology manages and controls traffic based on the flow direction (inbound or outbound) of an interface, source or destination IP address, user group, time range, and description.


Bandwidth management technology provides bandwidth guarantee and limiting to improve the bandwidth use efficiency and prevent bandwidth exhaustion.

  • Bandwidth guarantee: guarantees the bandwidth required by key services. When a network is busy, the bandwidth for key services is not affected.
  • Bandwidth limiting: limits the bandwidth occupied by non-key services, and prevents the non-key services from consuming much bandwidth to affect other services.

Bandwidth management helps network administrators properly allocate bandwidth resources, thereby improving the network operation quality.
