The fact that Comcast Corp. (Nasdaq: CMCSA, CMCSK) is using gear from Sandvine Inc. (London: SAND - message board; Toronto: SVC) to manage network traffic is one of the cable industry's worst-kept secrets. Although the two have never formally announced a relationship, it's been common knowledge for years that they've been working together.

But that fact officially became public record in late July when Comcast disclosed its ties to Sandvine in a filing with the Federal Communications Commission (FCC) , noting that the vendor's platform can "delay" unidirectional peer-to-peer (P2P) upload sessions when certain congestion thresholds are reached.
