Data distribution to nodes of a telecommunication network

A network manager of a telecommunication network, said telecommunication network comprising a central node, a first target node and a second target node,

• wherein said network manager comprises a compression module for compressing a first data set addressed to said first target node and a second data set addressed to said second target node, the compression module applying a compression algorithm to the whole of said first and second data sets, the algorithm recognizing whenever a sequence of data is present in multiple ones of said data sets and associating the sequence to a symbol for use in the compression of each of the multiple dam sets, thus providing a first compressed data set and a second compressed data set, and
• further wherein said compression module provides a first file comprising at least said first compressed data set and said second compressed data set, the network manager further comprising transmission means for transmitting said first file to said central node;
• wherein said network includes an intermediate node connected between said central and first nodes, further comprising the steps of:
• providing a third data set addressed to a said intermediate node;
• applying said compression algorithm to a data set including the whole of the first and third data sets, so that the first file includes a first compressed data set addressed to said first target node and additionally a third compressed data set addressed to the intermediate node:
• identifying in said first file a first file portion, wherein said first file portion comprises said first compressed data set and said third compressed data set;
• forwarding said first file portion to said intermediate node;
• identifying at the intermediate node, in said first file portion, the third compressed data set;
• recovering the third compressed data set at the intermediate node;
• and
• forwarding the first compressed data set from the intermediate node to said first target node without the third compressed data set.

A network node of a telecommunication network, the network including a management channel, said node comprising:

• a receiver for receiving a first file from a network manager over the management channel, the first file comprising at least a first compressed data set of management information addressed to a first target node and a second compressed data set addressed to a second target node, wherein said first and second compressed data sets are characterized by having been generated by the application of a compression algorithm to the whole of first and second data sets addressed to the first and second target nodes, respectively, the algorithm recognizing whenever a sequence of data is present in multiple ones of said first and second data sets addressed to the first and second target nodes and associating the sequence to a symbol for use in the compression of each of the multiple data sets;
• an identifying module for identifying in said first file at least a first file portion comprising said first compressed data set and a second file portion comprising said second compressed data set;
• and
• a forwarder for forwarding said first file portion to said first target node over the management channel, and forwarding said second file portion to said second target node over the management channel;
• said telecommunication network further comprising an intermediate node, said network node additionally including a third compressed data set addressed to the intermediate node and generated by the application of said algorithm to a data set including file whole of the first and third data sets, so that said first file comprises a first compressed data set addressed to said first target node and additionally a third compressed data set addressed to said intermediate node:
• said identifying module identifying in said first file said first file portion, wherein said
• first file portion comprises said first compressed data set and said third compressed data set;
• said forwarder forwarding the first file portion to the intermediate node;
• said intermediate node including
• an identifying means for identifying the third compressed data set in said first file portion;
• a splitting module for recovering the third compressed data set from the first file portion;
• and
• means for forwarding the first compressed data, set, without the third compressed data set, to said first target node.
