A system for facilitating network performance analysis. In an illustrative embodiment, the system includes a first module capable of quantifying network performance associated with a first portion of the network and providing a signal in response thereto. A second module is capable of ascertaining performance degradations in a communications link traversing plural portions of the network that are attributable to the first portion based on the signal. In a more specific embodiment, the second module further includes a third module adapted to ascertain degradations in network performance associated with a second portion of the network based on the signal and based on a performance parameter associated with both the first portion and the second portion of the network. In this embodiment, the first portion includes a wireless portion, and the second portion includes a wired portion. The performance parameter incorporates a Frame Loss Vector (FLV) associated with a communications link that traverses the wireless and wired portions of the network.
