A method, apparatus, and computer instructions in a data processing system for generating links. The present invention provides a mechanism for constructing a link in a manner that removes the need to rely on hard-coded strings. Generation of a page containing a link to a target is detected. A link is generated using parameters associated with the target.

Method and apparatus for portable universal resource locator and coding across runtime environments

A system and method ensure transmission of data elements between computers at a preselected quality of service. A computer in a layered reference model communication network requests a preselected quality of service for selected transmissions. An existing session is employed whereby transmissions having a variety of preselected quality of service guarantees are multiplexed onto the existing session. Data elements having the preselected qualities of service are transferred from service channels of another such layer. One, a system and method are provided for use between layer N+1 and layer N, wherein elements from two or more service channels from N+1 are transferred to one or more service channels in layer N such that a preselected quality of service is provided for the elements being transferred. Elements from a service channel having a higher priority, deadline, or period are transferred from the layer N+1 service channel to the layer N service channel before elements from a service channel having a lower priority, deadline, or period. In yet another embodiment, the number of elements are constrained whereby no more than a fixed number of such elements will receive service in a layer N service channel at a given point in time.

System and method for providing multimedia quality of service sessions

A system and method is provided to compliment use of priority for reserved traffic in multimedia computerized data communication networks, to insure that the opportunity for transmitting large, unreserved data frames is constrained. If frames transmitted when the server releases a token tend to be small, then the server will capture a larger portion of the bandwidth. Thus, a short bandwidth reservation acknowledgement is transmitted onto the ring by the client for selected frames which it receives. This is not addressed to any station on the ring. Rather it is simply transmitted at a non-zero priority less than the server's priority. The criteria which is employed by the client for such acknowledgement is that the sender will send a bandwidth reservation acknowledgement only when the IEEE 802.5 AC field is set, but will do so for a fixed amount of time or for a fixed number of received frames. This criteria provides an optimization reducing overall ring utilization, since the bandwidth reservation acknowledgement is only sent when the ring is congested. A communication network is disclosed which transmits an unsolicited acknowledgement at non-zero priority for each non-zero priority frame received, such system thereby being independent of the communication protocol employed by the network station.
