Question 1 Discuss the benefits and requirements of VOIP Question 2 Define the following Multicast routing protocol explain in detail with diagram Multicast backbone
Ethernet Addressing Every station on the network must have a unique physical address Offered by a six-byte physical address encoded on the network interface card (NIC)
In formation sharing at regular intervals For example every 30 seconds each router sends its information about the whole network to its neighbours. This sharing occurs
QUESTION a) How is an Intranet different from an Internet? b) State the main differences between a router and a switch c) Explain the function of a modem d) Calculate
I have a larget text file of 1MB, how do i break down into chunks of packets to send over UDP? byte b[]=new byte[1024]; FileInputStream f=new FileInputStream("input.txt
Star Topology Devoted point-to-point links to central controller (hub) Controller acts like exchange Advantages - Less expensive - Robustness Disadv
Length This is a 16 bit field that defines the total length of the user datagram, header plus data. This 16 bit can define a total length of a 0 to 65, 535 bytes.
Illustrate the working of networking Bus Topology All stations attach, by appropriate hardware interfacing called as a tap, directly to a linear transmission medium, or bus. F
In the VOIP system, let h be the total number of header bytes added to each chunk, including UDP and IP header. a) Assuming an IP datagram is emitted every 20 msec, find the tr
5. Suppose that frames are 1250 bytes long including 25 bytes of overhead. Also assume that ACK frame are 25 bytes long. Calculate the efficiency of Stop-and-Wait ARQ in a system t
