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： A method and system for enabling interconnection of VPNs is disclosed. An interconnection device manages an interconnection process at one or more facilities including, for example, a gateway device. The gateway device has information relating to a plurality of VPNs, and may facilitate interconnection between devices on at least two of the VPNs by determining that one device is in fact a member of a first one of the VPNs, and by forwarding connection parameters of the first VPN to the second VPN on an as-needed basis. In this way, the gateway allows interconnection without the need for a completely centralized decision-making process, and does so independently of the type of device and/or VPN(s) being used. Moreover, the gateway may implement only those VPN parameters needed by both VPNs to communicate with one another with a desired level of security, thereby simplifying the routing and forwarding processes associated with the actual communication occurring via the interconnection. The information related to the plurality of VPNs and their respective member devices may be stored in a mapping table at the gateway, and identification parameters of a device seeking interconnection and/or associated VPN parameters may be verified by the use of digital certificates.

摘要： The present invention relates to computer viruses and more particularly to a method and system for caching anti-virus file certificates. Each anti-virus certificate associated with a file comprises a file signature. The file signature is generated by a virus-free certificate authority, which avoids the system, which receives the file to check this file for all existing viruses. The virus-free certificate authority validates the file against all known viruses, using one or several anti-virus checkers. In case of new viruses, only the virus-free certificate authority is changed and the only process performed by the system receiving the file is to verify the file against the file signature included in the virus-free certificate, and to filter the file according predetermined rules. The present invention drastically simplifies the computing resources for detecting viruses on network devices such as IP Routers and Firewalls.
