1. A computer-readable storage medium, executable by a computer, storing a program for processing communication path requests, the computer-readable storage medium comprising:

  • a request receiving code segment that receives an external request message from an external system requesting establishment of a communication path through an autonomous system, the request message comprising a desired communication path profile including a desired level of communication path redundancy;

    a sending code segment that sends the request message to an identified server of the autonomous system;

    a response receiving code segment that receives a response message from the identified server, the response message indicating whether the communication path corresponding to the desired communication path profile is available, and, when the communication path corresponding to the desired communication path profile is unavailable, the response message further indicating at least one alternative communication path;

    a transmitting code segment that transmits the response message to the external system;

    an order receiving code segment that receives an order message from the external system and sends the order message to the identified server, the order message instructing one of establishment of the communication path corresponding to the desired communication path profile and one of establishment of the at least one alternative communication; and

    a communication path establishing code segment that establishes a communication path according to the order message.
