Another reason that telecommunications companies are so excited about VOIP technology is that it saves them the burden of maintaining two separate communications networks. If telephone calls were placed digitally over data networks such as the Internet, telecommunications companies (including UIS) would have to maintain and upgrade a single network instead...
Normal telephone calls are almost always completed and do not become disjointed because of a surge in traffic over the telephone network...
However, if Harvard's data network slows suddenly while a student is downloading a website, the student simply has to wait an extra second or two for the page to load. If the same were to happen during a telephone call, some part of the conversation would not get through or would be delayed to such an extent that normal conversation would be difficult. In fact, studies have found that delays of more than a half a second in voice conversations would render VOIP essentially useless...
...main problem with VOIP so far, says Donnelly, is that it doesn't handle sudden bursts of traffic over the network very well. If your roommate were to begin downloading a large file while you were talking on the phone, your conversation might begin to break...
...result, scientists are putting a tremendous amount of effort into developing quality of service technologies that can give priority to voice traffic when network slowdowns occur. According to Donnelly, once this technology is fine-tuned, VOIP should become ubiquitous both in national data networks and private intranets such as Harvard...
