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.
A method performed by an intermediary device in a network, the network comprising a first router, a second router, a third router, and the intermediary device, wherein the intermediary device is interposed between the first router and the second router, wherein the third router is coupled to the intermediary device, and wherein, at the first router, the second router is a next hop router for packets destined to a network-layer destination address, the method comprising:
A non-transitory computer-readable storage medium storing instructions that, when executed by an intermediary device in a network, cause the intermediary device to perform a method, wherein the network comprises a first router, a second router, a third router, and the intermediary device, wherein the intermediary device is interposed between the first router and the second router, wherein the third router is coupled to the intermediary device, wherein, at the first router, the second router is a next hop router for packets destined to a network-layer destination address, and wherein the method comprising:
An intermediary device, wherein the intermediary device is in a network comprising a first router, a second router, a third router, and the intermediary device, wherein the intermediary device is interposed between the first router and the second router, wherein the third router is coupled to the intermediary device, wherein, at the first router, the second router is a next hop router for packets destined to a network-layer destination address, and wherein the intermediary device comprising:
