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： In a packet switched communications system an incoming real-time packet is imbedded after the next block of data of the non-real-time packet being transmitted. This object is accomplished by transmitting each packet along with at least a 1-byte trailer which is used to indicate the packet type, whether the current block of non real time data is preempted or whether the current block of non real time data is resumed.

摘要： An arbitration method and device for a data processing system wherein N units share a common resource, to allocate the shared resource to a given unit selected from a number of units requesting access thereto.An age value is assigned to each unit and corresponds to the age of the request that will be made by the unit. During an arbitration cycle, a unit whose request will be serviced, if the shared resource becomes available, is selected, this unit being the one whose request has an age value corresponding to the oldest request. Then, the age value associated with each unit is updated when the resource is available, the age of the selected unit assuming a value corresponding to that of the most recent request, the ages of the units not selected that correspond to requests more recent than the one made by the selected unit being increased by a given quantity, and the ages of the units not selected that correspond to requests older than the one made by the selected unit remaining unchanged.
