| has gloss | eng: Generalized processor sharing (GPS) was developed as a service discipline to share the capacity of congested communications links in an efficient, flexible and fair manner. It is not possible to implement generalized processor sharing exactly since it assumes fluid traffic (infinitesimal packet sizes), but GPS is useful as a benchmark against which realizable service disciplines can be measured. There are several service disciplines which track the performance of GPS quite closely such as weighted fair queuing (WFQ) also known as packet-by-packet generalized processor sharing (PGPS). |
