SUMMARY

Bandwidth Allocation Protocol (BAP) and Bandwidth Allocation Control Protocol (BACP) enhance multilink Point-to-Point Protocol (PPP) by dynamically adding or dropping links on demand. BAP is used for bandwidth management, determining when to add or drop links based on usage. BACP uses Link Control Protocol (LCP) to elect a "favored peer," which has precedence if multiple peers transmit the same BAP request. Both protocols are PPP control protocols and work together to provide bandwidth on demand. In addition, Link Discriminator is a new LCP option used to uniquely identify each link in a multilink bundle.

Enable or Disable BAP/BACP

To enable or disable BAP/BACP on a server-wide basis:
  1. In Routing and Remote Access Manager, right-click the server on which you want to enable BAP/BACP, and then click Properties.
  2. On the PPP tab, click to select the Dynamic bandwidth control (BAP/BACP) check box.

Configure BAP With Additional Phone Numbers

A Windows 2000 server with BAP enabled can also provide clients with additional phone numbers to dial if extra bandwidth is required. Using this option, clients only need to know one phone number, but can still use extra lines as needed. When a BAP-enabled remote access client requests another connection, the remote access server sends back a message that contains the phone number of an additional modem.

To configure BAP to provide clients with additional phone numbers:
  1. In Routing and Remote Access Manager, click Ports, click Properties, click a port, and then click Configure.
  2. Type the phone number of the modem connected to this port.
  3. Repeat for each additional modem port.

Modify Profile Settings

BAP policies are enforced using profile settings or Remote Access Policies. You can configure Remote Access Policies using Routing and Remote Access Manager, or from IAS Manager.

To modify the profile settings:

  1. start Routing and Remote Access Manager.
  2. Click Remote Access Policies, and click the policy
  3. click Edit Profile, and then click the Multilink tab. You can then modify any of the following settings:
    • Limit Maximum Ports: This sets the maximum number of ports a user can dial up.
    • Require BAP: Use this setting if clients should only use BAP to establish multilink connections.
    • % of Capacity and Duration: These values are used to determine when to drop an extra connected line and can be adjusted to meet your requirements.
