First Claim
Patent Images
1. A method comprising:
- determining an operating condition at a first router in a differentiated service network having a plurality of routers based on evaluation of incoming packets and computation of an effective load by each of the plurality of routers;
propagating an indication of said operating condition at said first router to a second router, wherein a signal indicating at least network traffic status is sent from each of the plurality of routers to a bandwidth broker, the signal of the operating condition of the first router being reflected in the indication; and
adjusting at least one parameter of constraint of incoming traffic flow based on said indication, wherein said adjusting comprises renegotiating the at least one parameter of constraint or providing a recommendation based on the at least one parameter of constraint,wherein said adjusting comprises performing parameter mapping and resource usage calculation.

Abstract
A differentiated service network having a plurality of routers. An operating condition such as stability may be determined at a first router. An indication of the operating condition may be propagated from a first router to a second router such as an edge router. Based on the indication of the operating condition, one or more parameters of a constraint may be adjusted. The indication may be a signal corresponding to a network traffic status.
