Deflection routing is the rerouting of Internet Protocol (IP) network packets to eliminate heavy data traffic at the router interface and avoid packet buffering when network packets are transmitted with same route contention. Deflection routing is used in modern networking to reduce system and infrastructure expenses.

Deflection routing is also known as hot potato routing.
Techopedia Explains Deflection Routing
During deflection routing, nodes receive autonomous network data packets, which are forwarded without buffering to the nearest destination point via the shortest available path. This process reduces traffic and network complexity.
Deflection routing functions optimally when implemented with optical networks.
Deflection routing disadvantages include:
- Network bandwidth is used inefficiently.
- Packets are received out of order.
- Quality of service (QoS) implementation is problematic.
