Estimating the term…
The invention relates to a bandwidth broker (34, 36) for a domain (30, 32) of a telecommunication system comprising a plurality of domains, said bandwidth broker being associated with at least one border router (40, 50) of the corresponding domain in such a way that it can obtain information about the routing tables of this border router in order to be able to allocate resources to data routes inside the domain and outside the domain. This bandwidth broker (34) comprises means for receiving from, or sending to, the associated border router (40) route exchange messages, and means for sending to, or receiving from, other bandwidth brokers (36) same route exchange information in order that this bandwidth broker, together with the other bandwidth brokers, relay route exchange messages between border routers (40, 50). Preferably, the bandwidth broker comprises means for delaying route changes until resources have been allocated to the new route, and means for blocking the route change if resources are not sufficiently available on the new route.
A bandwidth broker for a domain of a telecommunication system comprising a plurality of domains, said bandwidth broker being associated with at least one border router of the corresponding domain in such a way that said bandwidth broker can obtain information about the routing tables of this border router in order to be able to allocate resources to data routes inside the domain and outside the domain,
The bandwidth broker according to any of the previous claims, characterized in that said bandwidth broker is associated with a plurality of border routers of the corresponding domain.
The bandwidth broker according to any of the previous claims, characterized in that said bandwidth broker further comprises means for obtaining information about the route followed, from one border router to another border router inside the associated domain, by data of specific flows in order to be able to allocate resources to the selected route and/or perform admission control on the selected route and/or in order to identify the next network that the data will reach or go through.
The bandwidth broker according to any of the previous claims, characterized in that the exchange of information with the corresponding border router is according to the Border Gateway Protocol (BGP).
A telecommunication system comprising a plurality of bandwidth brokers according to any of the previous claims.
