Abstract
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 l…
