SiLK’s origins are in processing NetFlow v5 data, which is unidirectional. Changing SiLK to support bidirectional flows would be major change to the software. Even if SiLK supported bidirectional flows, you would still face the task of mating flows, since a site with a many access points to the Internet will display asymmetric routing (where each half of a conversion passes through different border routers).
