In the routing method and apparatus a second routing attempt via an alternate path from an originating node is implemented for a call given an unsuccessful routing attempt via a preferred route, i.e. the call is offered a further alternate path to the destination node. The evaluation of the effectiveness of the rerouting is updated at each call per traffic relationship (originating/destination node pair), using an evaluation storing device. A decision is made based on the evaluation as to whether the rerouting for this traffic relationship is to be maintained or throttled for following calls.

The invention relates to a communications system and a method for establishing a broadband connection, for example a multi-media connection between two or more users, by means of exchanges in a communications network, for example an ATM network. According to the invention, when the exchanges receive a request from a calling user to establish a broadband connection, said exchanges first establish a minimal connection between the users and once the minimal connection is in operation between the users, the requested broadband connection is established. The users of broadband network capacities, which have been reserved by the network at the request of the user, are billed during the call phase. Broadband connections of this type can receive a higher priority than the upgrade of minimal connections to complete connections. A voice connection comprising audio data constitutes for example a minimal connection. The broadband connection takes place for example between video telephones.

The dynamic routing of a communication network is to adapt itself to the respective traffic load in the network in a way which optimizes network throughput. The routing according to the invention solves this problem by a route fan for holding alternate routes for the overflow traffic, an alternate route previously contained in the route fan being removed from the route fan without replacement as soon as it is established that it is no longer available.

For distributing calls in a communication network, a central network authority that forwards calls from subscribers to servers for further servicing of the calls provides an optimally successful distribution, i.e. a low load-conditioned cleardown rate by the servers, even when it cannot directly register the workload of a server. In order to achieve this, the central network authority monitors the reason for the cleardown of a call by a server and excludes a server from the call distribution procedure for a specific time span when this server clears an allocated calldown due to lack of adequate capacity.

Whereas the network architecture for ATM-based access networks on the DSL forum has already been defined, work on Ethernet-based access networks is still in its infancy. The invention relates to a novel aggregation solution for use in Ethernet-based broadband access networks.

There is disclosed a method for switching IP packets between client networks and IP provider networks by way of an access network. In a network element of the access network an IP session between a client network and an IP provider network is registered by means of a Layer 2 address assigned to the client network and an IP address assigned to this Layer 2 address. In the network element an IP service connection between the network element and an IP provider network is defined by means of a Layer 2 address assigned to the IP provider network. Further an active IP session is assigned to at least one IP service connection and/or a plurality of active IP sessions are assigned to the same IP service connection. In the network element the switching of the IP packets from active IP sessions to service connections and vice versa is performed by means of the aforementioned assignments.

In current telecommunications services, it is usual for the service provider of the initiator (e.g. the caller or the A-side) of the communications connection to determine the price and charge the A-side accordingly. The other subscribers are not usually charged. The A-side service provider pays a compensation amount (balance) to the B-side service provider. This fee charging and payment system is too rigid for modern communications services. The inventive method solves this problem.

Two subscribers A and B are each connected to a network, e.g. by means of a leased line or a dialup connection. Subscriber A sets up a telephone connection to subscriber B. In the course of the telephone connection, a data connection additionally needs to be set up. A service provided by the telephone network operator and an appropriate method taking place on the subscribers data terminal equipment automatically transfer the data network addresses of the subscribers involved in a connection and also the connection configuration of the telephone connection to the subscribers data terminal equipment. This means that a data network connection can automatically be set up for a telephone connection on request.

The dynamic routing of a communication network should adapt to the traffic load existing in the network such that the network throughput is optimized. The inventive routing method solves this problem by a dynamic path fan, with alternate paths, upon whose only specifically selected alternate paths are incorporated.
摘要:
A method and routing system for the dynamic routing of traffic in a communication network wherein the dynamic alternate routing is adapted to the traffic load respectively present in the network in such a way that the network throughput is optimized. The alternate routing includes a dynamic path fan with alternative paths, during whose (re-) initialization the chronological sequence by which the alternative paths were removed from the path fan is taken into account.
