Abstract: Systems and techniques are described for path selection. A packet can be transparently intercepted at an intermediary device. Next, the intermediary device may modify one or more bits in the header of the packet. The intermediary device can then forward the packet to the next hop device. In some network configurations, the modifications to the one or more bits in the header of the packet may cause a downstream device to select a path that is different from the path that would have been selected by the downstream device if the one or more bits in the header of the packet had not been modified. A path selection policy can be used to determine whether or not one or more bits in the header of the packet are to be modified.

Abstract: Systems and techniques are described for configuring path selection in a network. The network can comprise a first router, a second router, a third router, a fourth router, and an intermediary device. The second router can be configured to use Differentiated Services Code Point (DSCP) while routing packets so that packets with a first DSCP value are routed through the third router, and packets with a second DSCP value are routed through the fourth router. The intermediary device can be configured to: (1) transparently intercept a packet forwarded by the first router to the second router, (2) determine whether the packet is to be routed through the third router or the fourth router, (3) modify a DSCP field in the packet based on said determining, and (4) forward the packet to the second router.
