    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： Today, a Client and an associated Server use a single IP priority for all the data packets exchanged over a TCP session used to transport the Telnet traffic (file transfer and screen related interactions). The present invention discloses a method and system to provide the Client with the capability, when exchanging a file with an SNA Host over a TCP session, to dynamically change (i.e downgrade) the IP priority associated to all data packets flowing to the TN3270 Server over the TCP session, during the whole duration of the file transfer. The associated Server, on receipt of a data packet from the client (due to screen related interactions or to file transfers), memorizes the associated priority and uses this priority over all packets that it sends back to the client. This allows IP network implementation to give higher priority treatment to the data packets due to screen related interactions (interactive traffic) over data packets related to file transfer (batch traffic). The priority used by data packets related to file transfer is customisable, to give maximum freedom to the network designer. For example, SNA true interactive traffic (due to screen related interactions) could flow on the highest priority, pure IP traffic could flow on any of the possible medium priorities and data packet due to file transfer could use the lowest priority within the network.

    摘要： Method in a telnet client for transmitting in a session, file traffic to an application through a telnet server in an Internet protocol (IP) network. The method includes assigning by the telnet client an IP transmission priority to file traffic different from the IP transmission priority used for interactive traffic and transmitting the file traffic to the telnet server using said assigned IP transmission priority.

    摘要： The present invention relates to a method and system for pre-loading access nodes with the location of more frequently requested resources. The method includes declaring each locally supported communication protocol for participating to control message exchanges between nodes supporting a same communication protocol; receiving a message to locate a target resource; searching for information related to the location of the target resource in the Local Directory Database; broadcasting an undirected message to the other access nodes in the network to locate the target resource; receiving a control message from the destination access node providing access to the target resource, this control message comprising information related to the location of the target resource; and storing the information related to the location of the target resource in the Local Directory Database.

    摘要： A method and system for delivering a datagram across multiple inter-network servers. The datagram is delivered from a source device having a first network level protocol to a destination device having a second network level protocol. The inter-network servers transport the datagram in accordance with a transport level protocol while the datagram has a transport priority defined by the first and second network level protocols. The source device delivers the datagram from a source port that designates the transport priority and the destination device receives the datagram at a destination port that also designates the transport priority. In accordance with the method of the present invention, either the source port or said destination port is first identified. The transport priority of said datagram is identified utilizing the transport priority designation of the identified source port or destination port. A current server capacity of each of the inter-network servers is determined. A server eligibility for each of the inter-network servers is determined in accordance with the determined current server capacity and the determined transport priority. Finally, the datagram is dispatched to one of the inter-network servers in accordance with the determined server eligibility.
