Abstract
The following description is directed to monitoring an interconnection network. In one embodiment, a method of monitoring an internal link of an interconnection network can comprise creating a network packet. The network packet can comprise a data-link-layer destination address corresponding to a management interface of a first router of the interconnection network, and a network-layer destination address corresponding to a host computer. The network-layer destination address can be within a subnet associated with a management interface of a second different router of the interconnection network. The internal link can connect the first router and the second router. The method can further comprise transmitting the network packet from the host computer, and determining one or more performance metrics of the internal link based, at least in part, on whether the network packet is received at the host computer.
