摘要： The present invention is directed to a high speed packet switching network and, in particular to a method and system for minimizing the time to establish a connection between an origin and a destination node. Due to high dynamicity of the traffic on transmission links, it is important to select a routing path according to a fully up-to-date information on all network resources. The simpler approach is to calculate a new path for each new connection request. This solution may be very time consuming because there are as many path selection operations as connection set up operations. On another hand, the calculation of paths based on an exhaustive exploration of the network topology, is a complex operation which may also take an inordinate amount of resources in large networks. Many of connections originated from a network node flow to the same destination network node. It is therefore possible to take a serious benefit in reusing the same already calculated paths for several connections towards the same node. The path calculated at the time the connection is requested is recorded in a Routing Database and updated each time a modification occurs in the network. Furthermore, alternate paths for supporting non-disruptive path switch on failure or preemption, and new paths towards potential destination nodes can be calculated and stored when the connection set up process is idle. These last operations are executed in background with a low processing priority and in absence of connection request.
摘要翻译：本发明涉及一种高速分组交换网络，特别涉及用于最小化建立起始节点和目的地节点之间的连接的时间的方法和系统。由于传输链路上的流量的高动态性，根据所有网络资源的完全最新信息选择路由路径很重要。更简单的方法是为每个新的连接请求计算一个新路径。该解决方案可能非常耗时，因为存在与连接建立操作相同的路径选择操作。另一方面，基于网络拓扑的详尽探索的路径计算是一种复杂的操作，在大型网络中也可能占用过多的资源。许多来自网络节点的连接流到同一目标网络节点。因此，可以在对相同节点的多个连接重复使用相同的已经计算的路径方面有很大的益处。在请求连接时计算的路径被记录在路由数据库中，并且每次在网络中发生修改时更新。此外，当连接建立进程空闲时，可以计算并存储用于支持故障或抢占时的非破坏性路径切换的备用路径和朝向潜在目的地节点的新路径。这些最后的操作在后台执行，处理优先级低，没有连接请求。

摘要： A method and system for optimizing transmission links bandwidth utilization in an Asynchronous Transfer Mode (ATM) packet switching network including switching nodes interconnected by high speed transmission links, said network being made to transport user data traffic including PTM traffic organized into variable length packets, each packet comprising a variable length data payload and an original fixed length PTM packet header. The original PTM header is converted into an ATM-like header including a flag (F) identifying the packet as being a PTM packet, a label indication made to orient the currently-considered PTM packet within the ATM network nodes, a count (CNT) field for storing the PTM payload length indication therein to enable locating the PTM payload end position and a Header Error Control (HEC) field for storing an ATM-like error control byte (HEC) therein, which enables transporting the PTM packets over the ATM network links without having to chop the PTM payload into predefined fixed length segments by adding dummy bits to the last segment if required.

摘要： A system for coding voice signal to optimize bandwidth occupation in a High Speed Packet Switching network while ensuring best voice transmission quality.The voice signal is first encoded using a conventional GSM like RPE/LTP coder providing first sub-frames of coded signal and tagging these first sub-frames as being non-discardable. In addition, a convenient difference between an RPE/LTP provided signal and a corresponding synthesized image is performed (see 36) and is also block encoded into second sub-frames which second sub-frames are tagged as being discardable sub-frames. Said second sub-frames when concatenated to corresponding first sub-frames provide so-called multirate frames. Then, when transmitting said multirate frames over the High Speed packet switching network, dropping discardable tagged data enables solution network congestion situations in any network node and at random with no significant disturbing effect over the voice communication operation.

摘要： A packet switching communication system is improved by using a packet header structure which does not require a fixed format. The packet header comprises a chain of 2 byte command/data segments. Each command/data segment contains generic bits and a routing field. One of the generic bits (bit 1) allows the header to be extended with another command/data segment.

摘要： A method and system for implementing secure network communications between a first device and a second device, at least one of the devices communicating with the other device via a firewall device, are provided. The method and system may include obtaining an encryption parameter that is shared by the first device, second device and firewall device. A data packet sent by the first device may then be copied within the firewall device, so that decryption of the copy of the data packet within a portion of the firewall device may take place. In particular, the portion of the firewall device in which decryption takes place is defined such that contents of the portion are inaccessible to an operator of the firewall device. Thus, scanning of the decrypted copy of the data packet for compliance with a predetermined criterion may take place within the firewall device, without an operator of the firewall device having access to the contents of the data packet to be transmitted. Thereafter, the original data packet can be forwarded to its originally intended recipient.

摘要： The present invention relates to a system and method for dynamically adjusting the bandwidth of a continuous bit rate virtual path connection established between a source node and a destination node within a packet or cell switching network comprising a plurality of nodes interconnected with transmission links. In the network, a bandwidth management server having access to information concerning network nodes and transmission links is defined. This server is informed each time a virtual path connection or a virtual channel connection is established on the network with an indication concerning the initial bandwidth reserved for said connection. The server detects and shares, on a continuous or periodical mode, the bandwidth which is available on transmission links among the bandwidth adjustable continuous bit rate virtual path connections and determines for each connection a new bandwidth. The source node is informed each time a new bandwidth is computed. It adjusts the bandwidth of the corresponding bandwidth adjustable continuous bit rate virtual path connection accordingly.
