摘要： A method is given for sharing reserved bandwidth between a plurality of connections issuing from a port of a node. A connection bandwidth is determined for each connection of the plurality of connections. An aggregate bandwidth is determined for all connections of the plurality of connections issuing from the port, the aggregate bandwidth being less than a sum of the connection bandwidth for all connections. The aggregate bandwidth is compared with a maximum access rate for the port, and in the event that the aggregate bandwidth does not exceed the maximum access rate, reserving the aggregate bandwidth for the port.

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： Method for transmitting high-priority packets in an IP transmission network based upon the Internet Protocol (IP) wherein low-priority packets or fragments of packets are transmitted between a sender and a receiver and at least a high-priority packet can be transmitted from the sender to the receiver by pre-emption of a low-priority packet or a fragment of packet. The method comprises in the sender, the steps of determining whether a low-priority packet or fragment of packet is being transmitted from the sender to the receiver when a high-priority packet has to be transmitted, setting to 1 a reserved bit within the IP header of the high-priority packet used as a pre-emption indicator if a low-priority packet or fragment of packet is currently transmitted, transmitting the high-priority packet with the pre-emption indicator set to 1 from the sender to the receiver, and resuming the transmission of the low-priority packet or fragment of packet at the end of transmission of the high-priority packet.

摘要： The present application discloses a method and system of sharing reserved bandwidth among several connections issuing from a same physical port in an origin node of a packet switching communication network comprising a plurality of nodes interconnected with transmission links. At each request for establishing a connection i from an origin node to a destination node, the dependent connection management process: selects for connection i a routing path comprising one or a plurality of links from the origin node to the destination node: identifies on the selected path all consecutive links starting from the origin node and shared with another connection issuing from the same physical port; reserves on each link of these identified consecutive links an aggregate bandwidth for all connections issuing from the same physical port, said aggregate bandwidth being less than the sum of the bandwidth reserved for each connection considered individually.

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。
