Core group communication

The core group bridge is the service that enables communication between core groups. A core group is a statically defined component of the high availability manager. Use this page to view the structure of your access point groups. Access point groups link core groups that are in the same cell or in different cells and allow the core groups to communicate with each other.

To view this administrative console page, click Servers > Core groups > Core group bridge settings .

Each access point group is a collection of core group access points. If you are configuring communication between core groups that are in the same cell, configure an access point group with a core group access point for each core group in the cell. If you are configuring communication between core groups in different cells, configure an access point group that has one core group access point for the local cell and a peer access point for each other cell.

Each core group access point has one or more bridge interfaces. Each peer access point has a proxy peer or one or more peer ports. A bridge interface is a server that is configured to communicate with other core groups by using a particular transport channel chain. Click Access point groups to configure the settings for each access point group that is configured.

Access point group - An access point group defines the core groups that communicate with each other. Each access point group consists of a collection of core groups.
- Core group - Specifies a core group that is in this access point group. Core groups are referenced by core group access points.
  - Core group access point - The core group access point defines the set of servers that provide access to the core group. Bridge interfaces define the servers that are in the core group access point.
    - Bridge interface - A bridge interface defines a node, server, and chain for the core group access point. The chain defines the transport channels that the server uses for receiving information. Typically, all the bridge interfaces in a core group access point use the same chain.
- Peer core group - Specifies a core group in a different cell. Define peer access points to communicate with peer core groups.
  - Peer access point - Each peer access point is used to communicate a core group in a different cell. Each peer access point corresponds to a core group access point that is in the peer cell. Use one or more peer ports or one proxy peer to define the communication settings.
    - Peer port - Each peer port identifies a bridge interface of a core group bridge in the peer cell.
    - Proxy peer - A proxy peer is used to identify the communication settings for a peer access point that cannot be accessed directly through peer ports. A proxy peer specifies a peer access point that can communicate with the destination core group. The specified proxy peer must be a peer access point that has defined ports.
