Quality of Service in Broadband Networks
In broadband networks, the Quality of Service is measured using two criteria. The first criterion is the probability of packet losses or delays in already accepted calls. The second criterion refers to the probability that a new incoming call will be rejected or blocked. To avoid the former, broadband networks limit the number of active calls so that packets from established calls will not be lost due to new calls arriving. As in circuit-switched networks, the Grade of Service can be calculated for individual switches or for the whole network.

Famous quotes containing the words quality of, quality, service and/or networks:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“But the quality of the imagination is to flow, and not to freeze.”
—Ralph Waldo Emerson (1803–1882)
“In any service where a couple hold down jobs as a team, the male generally takes his ease while the wife labors at his job as well as her own.”
—Anita Loos (1888–1981)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
