Introduction to Switching Systems Grade of Service (GoS): In telephone field busy hour traffic is used for planning purpose. Grade of service is measure of congestion , expressed as the probability that a call will be blocked or delayed. When dealing with GoS in traffic engineering , the clear understan ding of blocking criteria , delay criteria and congestion are essential. Blocking Criteria: If the design of system is based on the fraction of calls blocked (the blocking probability) then the system is said to be engineered on blocking basis. Blocking can occur when all devices are occupied , when demand of service is initiated.
