A broadcast channel has 10 nodes and total capacity of 16Mbps. It uses polling for medium access. Once a node finishes transmission, there is a polling delay of 100 µseconds to poll the next node. Whenever a node is polled, it is allowed to transmit a maximum of 1500 Bytes. The maximum throughput of broadcast channel is: 8 Mbps 14 Mbps 100/11Mbps 750/85 Mbps

Consider a 8Mbps token LAN with a ring latency of 256µsec. A host need to transmit seizes the token, and then it sends a frame of 1024 bytes removes the frame after it has circulated all around the ring and finally releases the token. This process is repeated for every frame. Assuming that only a single host wishes to transmit, then the effective data rate (in Mbps) is? 4.53 5.36 6.7 9.4

Suppose each station in IEEE 802.5 with 1bit delay is 48m apart from its neighbouring stations. Token is of 3 Bytes and propagation speed is 2.4 * 10^8 m/sec. To avoid overlapping in the 4Mbps token ring the monitor must insert 15 bits of artificial delay into ring. How many stations are there in the ring? A.2 B.3 C.4 D.5

A heavily loaded $1$ km long, $10$ Mbps token ring network has a propagation speed of $200$ meter per micro-second. Fifty stations are uniformly spaced around the ring. Each data packet is $256$ bits long, including $32$ bits of header. The token is of $8$ bits. What is the effective data rate of the network assuming the stations always have packets to transmit?
