México, DF., México ABSTRACT This paper presents a method called the Short Term Protection (STP) which is applied to fixed networks where flows1 are constrained to follow specific routes, where the admission-process is distributed, per-route, and where the traffic is sensitive to delay (like MPEG4 traffic).
The share of bandwidth of any route is protected, in the shortterm, against the traffic-increment of its intersecting-routes.
In the long term, in every congested link, the share of bandwidth between the routes that intersect at that link is proportional to the average relative measured demands of those routes.
The nodes act autonomously, without central administration.
This method is expected to: 1) help network administrators to have confidence, within a time-frame , about the amount of bandwidth they count on for every route; 2) allow a simple bandwidth management in the network, with prospect to be scalable to at least tens of nodes.
This paper presents the general and detailed operation of the ...
