Which describes multicast routing?
Select one:
a. Monitors the quality of service provided to existing
b. When multiple receivers are required to get the same data at approximately the same time
c. The reverse path forwarding algorithm
d. Transport layer protocol designed to reserve resources across a network for an integrated services Internet.

The average time needed for a packet to travel from source to destination ?
Select one:
a. Jitter
b. Delay
c. Packet Loss
d. Variation

One way to deal with speech distortions is to buffer the packets at the receiving host to smooth out the jitter.
Select one:
True
False

Answer 1

Which describes multicast routing?

b. When multiple receivers are required to get the same data at approximately the same time

• Multicast is used to send data packets to a subnet of hosts.
• The sender considers the destination as a single source but the host on the same network sharing the same multicast address will be able to receive the packets.

The average time needed for a packet to travel from source to destination?

b. Delay

the delay in travel from source to destination include

• Processing delay – the time needed for the router to process the packet
• Queuing delay – Time the packet held due to the routing process
• Transmission delay – the time it takes to transmit the packet's bits onto the link
• Propagation delay - time for the bits to reach the destination.

One way to deal with speech distortions is to buffer the packets at the receiving host to smooth out the jitter.

True

Buffering allows the synchronized output without any distortions and preserves the quality.
