A connection-oriented protocol in a packet-switched network guarantees a dedicated line - similar to how a circuit-switched network works.

Question

The question presents a statement and asks whether it is true or false in the context of network protocols and switching types.
First, consider what is meant by a connection-oriented protocol in a packet-switched network. A connection-oriented protocol establishes a connection before transmitting data, enabling sequencing, flow control, and error handling. However, in a packet-switched network, even with a connection-oriented approach, the underlying network typically shares links among many users and packets. This means that the path is not a permanently reserved, dedicated circuit for the entire communication session.
Next, contrast this with circuit switching. In a circuit-switched network, a dedicated physical or logical path is reserved for the entire duration of the communication, providing a constant reserved bandwidth and a fixed route.
Therefore, while a connection-oriented protocol in a packet-switched network provides an established session and reliable delivery semantics, it does not guarantee a dedicated line or circuit for the duration of the transmission. The network remains shared, and resources can be interleaved with other traffic, subject to the protocol’s control mechanisms and QoS policies.
Common misconceptions to watch for include mistaking connection establishment for a guaranteed exclusive channel, or assuming that virtual circuit concepts (like those in some packet-switched networks) create a truly dedicated path. In reality, even virtual circuits provide a logical connection over a shared infrastructure, not a guaranteed exclusive path for all time.
In summary, the statement conflates the guarantees of circuit-switched networks with those of connection-oriented packet switching; the former guarantees a dedicated path, while the latter does not, even though it establishes a connection for reliability and order.
