Comparison of Datagram and Virtual Circuit Subnet
The working principle of CSMA

 

Feature Connectionless Connection-oriented
How is data sent? one packet at a time as continuous stream of packets
Do packets follow same route? no virtual circuit:  yes
without virtual circuit:  no
Are resources reserved in network? no virtual circuit:  yes
without virtual circuit:  no
Are resources reserved in communicating hosts? no yes
Can data sent can experience variable latency? yes yes
Is connection establishment done? no yes
Is state information stored at network nodes? no virtual circuit:  yes
without virtual circuit:  no
What is impact of node/switch crash? only packets at node are lost all virtual circuits through node fail
What addressing information is needed on each packet? full source and destination address virtual circuit:  a virtual circuit number
without virtual circuit:  full source and destination address
Is it possible to adapt sending rate to network congestion? hard to do virtual circuit:  easy if sufficient buffers allocated
without virtual circuit:  harder to do
