Comcast tries to stonewall the FCC

THE GIANT US cable TV and Internet Service Provider (ISP), Comcast told the Federal Communications Commission (FCC) Tuesday that blocking customers' file transfers is a fully legitimate exercise of its network management rights.
Late last year, the Associated Press and others caught Comcast surreptitiously injecting reject packets into customers' file transfer sessions over the Internet.
As we reported at the time, consumer rights groups then filed formal complaints against Comcast with the FCC. Comcast's statement to the FCC yesterday was made in the context of the FCC's regulatory investigation of those complaints.
Comcast customers have alleged that its interruption of Peer-To-Peer (P2P) file transfers violates the principle of Network Neutrality, which requires all types of Internet traffic to be treated equally by service providers.
Customers have also charged that Comcast interferes with users' downloads of movie files because those might compete with the company's premium cable TV channels and on-demand movie purchases.
In its formal comments, Comcast claimed that it hampers some file transfers in order to manage its network. It said that it only curbs some file-sharing sessions to prevent a few subscribers from clogging up network traffic in neighbourhoods.
Comcast's claims are disingenuous, in that they serve to obscure that fact that Comcast oversells its cable bandwidth. Because the cable loop in any particular neighborhood is shared by all of its subscribers and has limited total bandwidth, Comcast sells more customers high advertised bandwidths than it can deliver.
This is a widely recognised limitation of cable Internet access, but Comcast and other cable ISPs won't readily admit it and, understandably, don't advertise it.
Furthermore, cable bandwidth is asymmetrically provisioned, such that more bandwidth is allocated to downlinks than to uplinks. If subscribers upload fil es on a particular neighborhood cable loop, they can exhaust the available uplink bandwidth. Comcast alluded to this problem in its formal comments to the FCC.
Having oversold its bandwidth infrastructure and thus promised its subscribers more than it can deliver, Comcast took the only tack it could take, that is, claim that its interference with its customers' Internet traffic is necessary and justified in order to manage its network.
Freakin' Comcast.
