line 26 the eventset is maintained as a priority queue of Event objects ( P Q is a typedef, given at line 10, that hides a complicated priority-queue template instantiation) The remaining data members are freeModems,which is initially the number of modems in the simulation but changes as users connect and hang up, and avgCallLen and freqofcalls, which are parameters of the simulation Recall that a dial-in attempt will be made every f reqofcalls ticks The constructor, declared at line 15, and implemented in Figure 147 initializes these members and places the first arrival in the eventset priority queue The simulation class consists of only two member functions First, nextcall,shown in Figure 148 adds a dial-in request to the event set It maintains two static variables: the number of the next user who will attempt to dial in and when that event will occur Again, we have made the simplifying assumption that calls are made at regular intervals In practice, we would use a random number generator to model the arrival stream

The other member function is runsim,which is called to run the entire simulation The runsim function does most of the work and is shown in Figure 149 It is called with a single parameter that indicates when the simulation should end As long as the event set is not empty, we process events Note that it should never be empty because at the time we arrive at line 10 there is exactly one dial-in request in the priority queue and one hang-up request for every currently connected modem Whenever we remove an event at line 10 and it is confirmed to be a dial-in, we generate a replacement dial-in event at line 37 A hang-up event is also generated at line 32 if the dial-in succeeds Thus the only way to finish the routine is if nextcall is set up not to generate an event eventually or (more likely) by executing the break statement at line 12 Let us summarize how the various events are processed If the event is a 6 hang-up, we increment f reeModems at line 1 and print a message at line 17 If the event is a dial-in, we generate a partial line of output that records the attempt, and then, if any modems are available, we connect the user To do so, we decrement freeModems at line 26,generate a connection time (using a Poisson distribution rather than a uniform distribution) at line 27, print the rest of the output at line 28, and add a hang-up to the event set (lines 30-32) Otherwise, no modems are available, and we give the busy signal message Either way, an additional dial-in event is generated Figure 1410 shows the state of the priority queue after each deleteMin for the early stages of the sample output shown in Figure 144 The time at which each event occurs is shown in boldface, and the number of free modems (if any) are shown to the right of the priority queue (Note that the call length is not actually stored in an Event object; we include it, when appropriate to make the figure more self-contained A ' ' for the call length signifies a dial-in event that eventually will result in a busy signal; however, that outcome is not known at the time the event is added to the priority queue) The sequence of priority queue steps is as follows
