Understanding DAA

Understanding DAA


  • Traffic identification: classifies traffic into different types according to the destination IP addresses users access.
  • Tariff level: identifies the data flows destined for the specified address so that the device can collect statistics and enforce differentiated policies on different types of traffic.
  • Traffic group: associates classified traffic with tariff levels.


Figure 2-1 shows the network of DAA service. The Switch works with an accounting server to implement destination-based accounting.

Figure 2-1  Network of DAA service

During a user authentication and network access process, DAA service process is as follows:

This process assumes that users have passed authentication.

  1. A user goes online and traffic is generated.
  2. When the user accesses Network1 or Network2, the device resolves the destination address from user traffic, and matches the destination address against ACL, which is the traffic identification rule.
  3. The device obtains the tariff level corresponding to the ACL in the traffic group, and maps the traffic to the corresponding tariff level.
  4. The device performs traffic statistics collection according to the tariff level.
  5. (Optional) The device periodically sends an interim accounting packet to the accounting server. The packet carries accumulative traffic statistics corresponding to each tariff level.
  6. (Optional) After receiving an interim accounting packet, the accounting server parses traffic information corresponding to each tariff level and performs interim accounting based on certain rules.
  7. When the user requests to go offline, the device sends an accounting stop packet to the accounting server. The packet carries traffic statistics at each tariff level during this online process of the user.
  8. After receiving an accounting stop packet, the accounting server parses traffic information corresponding to each tariff level during the entire online process and performs accounting based on certain rules.
  9. The user goes offline.
