There are several ways to reduce network congestion. Subnetting and adding routers will break up broadcast domains and traffic. Adding VLANs will do the same while adding security. Upgrading the speed of NICs and wiring, i.e. moving from 10BaseT to 100 or 1000, will reduce congerstion as will moving from half duplex transmissions to full duplex transmissions.
To reduce congestion & optimize the IP address space.

congestion is Traffic in excess of network capacity. it occurs network layer and it is one of the function of network layer.
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
at the network layer, congestion control mechanism takes place
Increase the bandwidth.
It don't control congestion that is up to the routers and gateways as they are the ones that look at the traffic and figure out the best way to send something over the internet.
Increase the bandwidth.
Bottlenecking
Yes, roundabouts can reduce traffic congestion by improving traffic flow and reducing the number of potential conflict points compared to traditional intersections.
The three general approaches to explicit congestion signaling are: Network-assisted signaling: This involves the network actively informing end-hosts about congestion through dedicated signaling messages, allowing them to adjust their sending rates accordingly. Feedback-based signaling: This method relies on feedback from the end-hosts, where the network observes traffic patterns and informs senders of congestion through packet loss or delay metrics, prompting them to reduce their transmission rates. In-band signaling: This approach integrates congestion information directly into the data packets themselves, allowing senders to receive congestion notifications as part of the normal data flow, enabling more immediate adjustments to their sending behavior.
