DAA Overview

DAA Overview

Definition

Destination address accounting (DAA) is a technology that implements traffic rate limitation and traffic accounting based on destination addresses in user packets.

Purpose

DAA is performed at different tariff levels defined based on different destination addresses in user packets. DAA implements the following functions:

  • Accounting based on destination addresses in user packets: DAA can distinguish between long-distance network service traffic and local network service traffic, enabling operators to use differentiated tariffs. For example, if the local network service provider has to lease a line from the long-distance network service provider, traffic of the long-distance network and local network services can be charged separately so that profits of the local network service provider are guaranteed.
  • Bandwidth limitation based on destination addresses in user packets: If a user accesses an education network, such as a campus network, the network service is usually free of charge or is charged at a low price, and the bandwidth is not limited. If a user accesses a non-education network, the network service is usually charged at a high price and the bandwidth is limited.
  • Traffic scheduling based on priorities of destination addresses in user packets: DAA enables an operator to grant different priorities for different portal pages. Services of a portal page provider with a higher priority are better protected in the case of network congestion, improving the competitiveness of the portal page provider.

Benefits

Benefits to carriers

This feature brings the following benefits to carriers:

  • Income increase: DAA can distinguish between long-distance network and local network service traffic, enabling operators to use differentiated tariffs. This guarantees profits of local network service providers.
  • Differentiated traffic rate limitation, scheduling, and accounting: Operators can use the BAS to differentiate services based on network segments of servers that user accesses, and perform traffic rate limitation, scheduling, and accounting based on service contents.
