摘要： A method and system for reserving a virtual connection from a source workstation to a destination workstation. Packets of data are transmitted over a network between an ingress node of the source workstation and an egress node of the destination workstation. In accordance with the method of the present invention, a reservation request is delivered from the source workstation to a reservation server. The reservation server includes a user database for storing the identification of each user allowed to access to the reservation server and also stores the rights of each user. The reservation server further includes a network database for storing the information describing a network capacity required to set up the virtual connection. A verification is then performed to determine whether or not the reservation request may be validated in view of user information within said source workstation. A second verification is performed to determine whether or not the capacity of said network is sufficient to meet the requirements of the reservation request. In response to the capacity of the network being sufficient to meet the requirements of the reservation request, a virtual connection is established from the ingress node to the egress node.

摘要： A system for providing prioritized queue management within a data transmission network node that supports different types of data frame traffic is disclosed herein. The system includes a frame buffer for storing an incoming frame that has an identifiable frame type. A queue is pre-associated with the frame type of the incoming frame such that upon arrival of the frame at the network node, the queue stores a location address at which the frame is stored within the frame buffer such that the frame is maintained within the queue. The queue that contains the frame is stored within a frame table. Processing means are provided for determining a time at which the queue forwards the frame from the frame buffer in accordance with a pre-determined sub-queue priority list. The system further includes time metering means associated with the frame for temporally assigning the frame to a virtual sub-queue among multiple virtual sub-queues that are associated with the queue. The sub-queues are sequentially ordered according to the predetermined sub-queue priority list such that the processing means selects a highest priority frame for forwarding from the frame buffer.

摘要： A method and a system of network capacity planning for use in a high speed packet switching network. The network comprises a plurality of switching nodes interconnected through a plurality of communication links, each of the switching nodes comprises means for switching packets from at least one input link to at least one output link. Each of the output links is coupled to at least one buffer in the switching node for queuing packets before they are transmitted over the output link. In each of the switching nodes and for each of the output links, a time distribution of the occupancy of each buffer during a predetermined monitoring time period is measured, and stored in a centralized memory location. Then, the buffer occupancy time distribution data are retrieved from the centralized memory location in all the switching nodes, gathered and stored in a network dedicated server. These buffer occupancy time distribution data for all the nodes are transmitted from the dedicated network server to a network monitoring center. In the network monitoring center, the buffer occupancy time distribution data are integrated on a larger time scale, and stored. Finally, the integrated buffer occupancy time distribution data are used to apply network capacity planning actions to the network resources.

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： Method of reinitializing dictionaries in a data transmission system using data compression having a transmit device and a receive device, and in which strings of characters have to be transmitted in a compressed form, the transmit device having a transmit dictionary storing codewords associated with the strings of characters which are transmitted instead of the strings of characters, the receive device having a receive dictionary storing codewords associated with the strings of characters, and both dictionaries being updated each time a new string of characters has to be transmitted so that the contents of the dictionaries remain identical. This method saves at least the addresses of the parts of the transmit or receive dictionary which have to be modified by a dictionary updating operation, builds a check message based upon the contents of the transmit dictionary updated by the dictionary updating operation, transmits the check message from the transmit device to the receive device, and then deletes in both dictionaries the parts which are determined by the saved addresses in the event that the check message does not correspond to the contents of the updated receive dictionary. This enables both dictionaries to be reinitialized in an intermediate state without being reset.

摘要： In a token ring network a periodic recirculating frame having a plurality of information carrying slots and a header section is used for enabling a plurality of telephone stations to exchange information carrying signals. The header is provided with a token which can assume one of three states. In the first state FF, a telephone station wanting to make a call, changes the token to the second state 00 and inserts call establishment information in the header. A server station also connected in the ring detects the second state as a request to establish a connection from and to a station specified in the header. The server changes the token to the third state AA and inserts a slot assignment in the header. All stations receiving a frame with a token in the third state examine the header. The calling station implies confirmation of the requested connection and the called station is made aware of the call and the identity of the caller. When this frame returns to the server the token state is set to FF and another station on the ring can request a slot for communication with another station.
