  • Method and apparatus providing distributed authorization management of communication sessions
    Patent number: 7028073
    Abstract: A mechanism for authorizing a data communication session between a client and a first server is disclosed. When a request is received to establish a session with a particular entity that is associated with the client, it is determined whether authorization of the session can be performed locally at a second server. If it is determined that authorization of the session can be performed locally at the second server then, the first server is informed that the session may be established between the client and the first server for the particular entity. A third server that is associated with the particular entity is identified and once the first server is informed that the session may be established, the third server is informed that the session has been authorized to be established for the particular entity. However, if authorization of the session cannot be performed locally at the second server then, the third server is requested to authorize the session between the client and the first server.
