Converged Networks - Question And Answer

NETW320Review QuestionsChapter 1List twain types of switched networksThere are many types of switched networks of which the two most joint types are go switched and megabucks switchedList two contraventions in the midst of software system switched networks and rophy switched networksThe basic difference between a portion switched and circle switched network is the lack of a dedicated circuit between the users in the former type of network . In software package switched network a dedicated circuit is established between end-to-end points , which in piece of ground switched network the circuit is shared by multiple subscribersanother(prenominal) difference is that the circuit reverse statically reserves the required bandwidth in advance , spell packet switching acquires and releases bandwidth as and when neededGive an example of packet switched networkInternet is largely found on packet switching where the data is sent in packets and the same data path is shared among many users in the networkGive an example of circuit switched networkThe most familiar example of circuit switched network is the telephone network which provides 64kbps circuits for the transfer of voice signals between usersList two differences between data relations and voiceThe first difference is that voice is sensitive to jitter and time delays while LAN-based data art is not so . In addition , voice traffic for consistent fast throughput with no requirements for error recovery procedures while data traffic priorities on error-free contagion with a overmuch larger acceptability for timing variancesWhat are data social social unit called at forge 2Data unit is called frame at layer 2What are data unit called at layer 3Data unit is called packet at layer 3Give an example of connectionless switchingAn example of connectionless packet switching communications communications protocol is IP networkWhat is a protocol stackA protocol stack is a framework utilize to organize and recognise networking protocol .

Each layer in a protocol stack serves a particular networking needWhat is technology convergenceTechnological convergence essentially means the way different technologies are converging to pass away one . The wireless communication field has clear examples demo technological convergence and fusion The availability of high bandwidth has enabled transmission of not only voice , but also pictures and multimedia system to be transferred over a single carrier technology at the same timeList two types of network that could be convergedOne of the examples a converged network is the integration of the telephone network with the IP-based data networks used for broadband internet connectionsChapter 2List two advantages of VOIPSending voice over IP networks has many advantages . Two of the biggest advantages are efficient use of purchasable connections which also leads to a lot of cost savings . Another advantage is that the VOIP connections are packet oriented which means there are many alternative paths possible for each packet while also adds to the efficient usage of available circuitsList two new services of VOIPEmerging VOIP technologies like Session Initialization protocol (SIP and Media Gateway Control Protocol (MGCP ) are providing new IP-based voice...If you wishing to get a full essay, order it on our website: Orderessay
