Method for transmitting data, data transmitting component and data receiving component

Abstract

The present invention relates to a method for transporting data between a data transmitting network element and a data receiving network element via a point-to-point connection in a communications network. This communications network comprises at least one transmitting network element and at least one data receiving network element. An Internet Protocol Control Protocol request for a service level of sending data is sent to the data receiving element by the data transmitting element. This Internet Protocol Control Protocol request is received by the data receiving element. The data receiving element then determines a service level based on a predetermined criterion and formulates an Internet Protocol Control Protocol propose of the service level that can be provided to the data sending element. Subsequently the Internet Protocol Control Protocol propose of the service level is sent towards the data transmitting element. The Internet Protocol Control Protocol propose including the service level propose in its turn is received by the data transmitting element and used for sending data towards the data receiving element. It is also possible to initiate the (re-)negotiation by the data receiving network element, by sending Internet Protocol Control Protocol messages to the data transmitting element. As an alternative the data transmitting element is able to notice that a provided service level is not satisfying and that it formulates another request for a service level that is satisfying for the data transmitting element. Re-negotiation of an existing service level specification is also possible by sending Internet Protocol Control Protocol messages requesting another service level specification.

Description

technical field [0001] The invention relates to a method for transmitting data via a point-to-point connection in a communication network, an associated data sending device and a data receiving device and associated software modules. Background technique [0002] Such a method and associated network elements are generally known in the prior art. A data sending network element sends data packets to a destination via a communication network via an edge network element of the communication network. In order to prevent network congestion caused by data-sending network elements sending data without regard to capacity constraints and other possible constraints, a maximum traffic class is negotiated between each such data-sending network element and edge elements. Such a business-level specification is now negotiated between the two parties in a static manner, such as by phone call or by e-mail. There may be a supervisory device in the edge element to check whether the incoming d...

This is a very time-consuming and inefficient way of negotiating business-level specifications

Auto-negotiation and re-negotiation and continuous updates of business-level specifications may not be present
