Embodiment Construction

[0014] figure 1 A diagram is shown to explain the principle of the transmission by means of the method according to the invention. Data from source Q should be transferred to sink or destination Z. Here, source Q and sink Z are network elements of a data network or a communication network. The network element of source Q and the network element of sink Z are connected to each other through two different transmission lines, transmission paths, paths, routes or links, and they may be part of a data network containing other network elements. That is to say, the transmission line may contain other network elements not shown. In this case, source Q is connected to sink Z via transmission line or route A on the one hand and via transmission line or route B on the other hand.

[0015] In principle, the data are inserted in the source Q on the sender side into a virtual concatenation group VCG, which for example consists of 18 virtual containers. Half of the virtual containers in ...

Abstract

The invention relates to a method for transmitting data in a data network using virtual containers, which are combined to form a virtual concatenated group by means of the Link Capacity Adjustment Scheme, LCAS. The virtual concatenated group is sub-divided on the send side into a first virtual concatenated group and a second virtual concatenated group. Data of a first type is inserted on the sendside into the first virtual concatenated group and data of the second type is inserted into the second virtual concatenated group. Said data is then transmitted via the data network.

Description

technical field [0001] The invention relates to a method for transmitting data and a network element of a data network. Background technique [0002] Data networks are used for data transmission, for example networks of the Synchronous Digital Hierarchy (abbreviated SDH) or Synchronous Optical Networks (abbreviated SONET). Through these networks, data is transmitted by means of a virtual container (Virtual container, VC for short). For this purpose the data are inserted into virtual containers on the sender side. A virtual container basically consists of a part for valid data and a part for overhead data used for control, management, administration, etc. of a network or a container. Virtual containers can be interconnected into cascaded virtual containers or logically connected virtual containers. These virtual containers are also known as virtual logical connection part signals. A plurality of such virtual containers or cascaded virtual containers can be combined into a...
