Method, device, and system for admission control in metropolitan area network
First Claim
1. A system for admission control in a Metropolitan Area Network (MAN), comprising:
- a resource manager (RM), configured to converge resource reservation requests from users, determine whether a total bandwidth value in the converged resource reservation requests is larger than a preset bandwidth threshold of a transmission path, and if the total bandwidth value in the converged resource reservation requests is larger than the preset bandwidth threshold of the transmission path, establish a new transmission path using an identifier (ID) number of the transmission path distributed to the users,wherein a bandwidth value of the new transmission path is larger than the total bandwidth value in the converged resource reservation requests, the resource reservation requests contain bandwidth values to be occupied for data transmission, and the total bandwidth value comprises a sum of the bandwidth values to be occupied for data transmission in the converged resource reservation requests;
a path manager, configured to be connected to the RM, receive control signals sent by the RM, and configure new network element parameters of the new transmission path according to the control signals; and
an application function module, configured to be connected to the RM, and send the resource reservation requests to the RM through Diameter interfaces according to session service requests received from the users, the session service requests containing the bandwidth values to be occupied for data transmission, wherein the resource reservation requests contain the bandwidth values to be occupied for data transmission.

Abstract
A method comprises converging resource reservation requests from users, wherein the resource reservation requests contain bandwidth values to be occupied for data transmission; determining a total bandwidth value comprising a sum of the bandwidth values to be occupied for data transmission in the converged resource reservation requests; determining the total bandwidth value is larger than a preset bandwidth threshold of a first transmission path having an identifier (ID) number; and establishing a second transmission path using the identifier (ID) number of the first transmission path distributed to the users, wherein an ID number of the second transmission path is the ID number of the first transmission path and a bandwidth value of the second transmission path is larger than or equal to the total bandwidth value.
