Protocol/Criteria	Connection-Oriented	Connectionless
Resource Allocation:	Resources need to be allocated.	No prior allocation of resource is required.
Utilization:	It often leads to low or underutilization of resources.	It ensures optimal usage of resources.
State info:	Lot of state related information needs to be stored.	Not much of information is required as packets are sent randomly.
Reliability:	It ensures reliable transfer of data.	Reliability is not guaranteed as it is a best effort service.
Connection:	Prior connection needs to be established.	No prior connection is established.
Delay:	There is more delay in transfer of information, but once conn. Established faster delivery.	However there is no delay due absence of connection establishment phase.
Packet travel:	In this packets travel to their destination node in a sequential manner.	In this packets reach the destination in a random manner.
Congestion:	Congestion is not at all possible.	It is likely that congestion occurs.
