So if your outbound traffic increased as much as your inbound traffic and you see a spike in UDP port 8247, you may not have realized that you signed up for helping CNN to stream out it’s video. CNN is using peer to peer technology through a Flash update.
Your computer just became a CNN streaming video node on their peer to peer backbone. Now the interesting things is in that plug in, it doesn’t say that this is what the intent of that plug in is. It just says that it’s a delivery enhancement. What it doesn’t say that it will now setup your computer as a streaming node for CNN.com.
Is that acceptable to your organization? For some it may not be. I’m tinfoily and paranoid enough that I would appreciated a nice eula telling me what’s included in that ‘enhancement’.
That flash client isn’t just serving you information, it’s making you part of the delivery process. Just be aware that it may add traffic to your network as well.
