THE TRANSPORT LAYER

1. WHICH OF THE FOLLOWING ARE TRANSPORT LAYER PROTOCOLS USED IN NETWORKING? *

a) TCP and FTP

b) UDP and HTTP

c) TCP and UDP

d) HTTP and FTP

2. TRANSPORT LAYER AGGREGATES DATA FROM DIFFERENT APPLICATIONS INTO A SINGLE STREAM BEFORE PASSING IT TO *

a) network layer

b) data link layer

c) application layer

d) physical layer

3. AT THE TRANSPORT LAYER, TO DEFINE THE PROCESSES, WE NEED TWO IDENTIFIERS CALLED

a) logical addresses

b) physical addresses

c) port addresses

d) None of the choices are correct

4. MENTION THE TYPES OF SOCKETS AND WRITE THE FUNCTION CALLS OF THE SOCKET *

5. WHAT IS MEANT BY TRANSPORT-LAYER MULTIPLEXING? *

a) Receiving a transport-layer segment from the network layer, extracting the payload, determining the destination IP address for the data, and then passing the segment and the IP address back down to the network layer.

b) Taking data from one socket (one of possibly many sockets), encapsulating a data chuck with header information – thereby creating a transport layer segment – and eventually passing this segment to the network layer.

c) Receiving a transport-layer segment from the network layer, extracting the payload (data) and delivering the data to the correct socket.

d) Taking data from multiple sockets, all associated with the same destination IP address, adding destination port numbers to each piece of data, and then concatenating these to form a transport-layer segment, and eventually passing this segment to the network layer.

6. WHAT IS MEANT BY TRANSPORT-LAYER DEMULTIPLEXING? *

a) Taking data from multiple sockets, all associated with the same destination IP address, adding destination port numbers to each piece of data, and then concatenating these to form a transport-layer segment, and eventually passing this segment to the network layer.

b) Receiving a transport-layer segment from the network layer, extracting the payload, determining the destination IP address for the data, and then passing the segment and the IP address back down to the network layer.

c) Taking data from one socket (one of possibly many sockets), encapsulating a data chuck with header information – thereby creating a transport layer segment – and eventually passing this segment to the network layer.

d) Receiving a transport-layer segment from the network layer, extracting the payload (data) and delivering the data to the correct socket.

7. DESCRIBE THE TCP FLOW CONTROL *

8. DESCRIBE THE CAUSES AND COSTS OF CONGESTION CONSIDERING THE FOLLOWING SCENARIOS

SCENARIO 1: TWO SENDER, A ROUTER, WITH INFINITE BUFFER.

SCENARIO 2: TWO SENDER, A ROUTER, WITH FINITE BUFFER.

9. WRITE THE RTP HEADER FIELDS *

10. MENTION THE RTCP PACKET TYPES *
