[1] In contrast, in conventional routing, routers in the network determine the path incrementally based on the packet's destination.
It does not allow a source to directly manage network performance by forcing packets to travel over one path to prevent congestion on another.
Many high-performance interconnects including Myrinet, Quadrics,[2] IEEE 1355, and SpaceWire support source routing.
[3] Because of security concerns, packets marked LSRR are frequently blocked on the Internet.
Studies have shown significant improvements in convergence times as a result of the reduced state that must be distributed by the controller into the network.
