摘要： A method for transmitting data frames with compressed headers in a multiprotocol data transmission network comprising at least one ingress node transmitting data to egress nodes. Each frame of data includes data bytes and a header which defines the transmission protocols. This method comprises the steps of comparing the address field of the frame to a list of address fields corresponding to the current flows of data, selecting candidate headers associated with flows having the same address, determining a compressed header based upon the position and the number of bytes that differ between the frame header and the candidate header, selecting as reference header the best candidate header based on compression ratio, and transmitting a compressed data frame wherein the data bytes are preceded by a reference label and a compressed header including a field defining the position and the number of consecutive bytes in the portion being compressed, a field including the different bytes, and a field including the portion of header which is not compressed.

摘要： Method of self-learning for a switching node in a data transmission network (10) wherein Internet Protocol (IP) data frames are transmitted between a sending unit (20 or 24) and a receiving unit (22 or 26) via an ingress switching node (12) linked to an egress switching node (16 or 18) by a plurality of intermediate switching nodes (14) interconnected by trunks. The method consists principally in generating, in the input port/trunk interface of the switching node, a switch header including a source identification field, a destination identification field and a temporary label identifying the flow of data in response to its first data frame, this first switch header being concatenated to said data frame before being transmitted to the router interface of the switching node via its switch engine when the data frame does not belong to a known flow of data and the router has to define the routing of the flow of data. An update message is sent back from the output trunk/port interface to the input port/trunk interface to update the latter with the destination identification and with a switching label replacing the temporary label associated with the flow of data, in order to transmit the following frames of the flow of data directly to the trunk/port interface by using this switching label.

摘要： Method and system for assigning labels in a data transmission network in which flows of data, composed of packets, are transmitted from a source node to a destination node through a plurality of switching nodes. The network is further characterized in that a label, identifying each flow of data, is added to each packet of the flow of data before the packet is transmitted from a transmitting node to an adjacent receiving node in the network. This so-called identification label is recognized by the receiving node as the identification of the flow of data to be transmitted. Each node in the network assigns an identification label to the packets when a new flow of data is received by the node. Both the transmitting and receiving nodes in the network generate an identical label for a given flow of data. Thus, the overhead associated with the sending of assigned labels from assigning nodes to corresponding upstream or downstream transmitting or receiving nodes in the network is avoided.
摘要翻译： 在数据传输网络中分配标签的方法和系统，其中由分组组成的数据流通过多个交换节点从源节点传送到目的地节点。 该网络的特征还在于，在将数据包从发送节点发送到网络中的相邻接收节点之前，将标识每个数据流的标签添加到数据流的每个分组。 该所谓的识别标签被接收节点识别为要发送的数据流的标识。 当节点接收到新的数据流时，网络中的每个节点都会为数据包分配一个标识标签。 网络中的发送和接收节点都会为给定的数据流生成相同的标签。 因此，避免了将分配的标签从分配节点发送到网络中的相应的上游或下游发送或接收节点所涉及的开销。

摘要： An apparatus for keeping several versions of a file includes a memory and an overwriting unit coupled to the memory. An initial version of the file is stored in a first area of the memory, and a current version is stored in a second area of the memory, the current version resulting from a modification of the initial version. The overwriting unit substitutes the current version for the initial version in response to a validation signal. The validation signal is produced after the current version has been permanently stored.
