The Internet is Changing

It is said one of the three largest U.S. cable operators now is using technology from Procera Networks to classify and prioritize packets on a much more granular basis than simple Multi-Protocol Label Switching would imply.

Traffic shaping, though some object to its use, seems not to be an optional practice anymore, as the Internet increasingly is asked to supply real-time services such as voice, video and audio that are tough to deliver with assured quality.

That's a big change for the Internet, to be sure. But it seems an irreversible change, precisely because the Internet and other IP networks now are asked to support real-time services that require quality of service control.

Procera Networks announced availability of the PacketLogic PL10000, the latest in the PacketLogic family of deep packet inspection products and said to be the industry's highest-performance DPI platform, with four times the capacity of its nearest competitor.With up to 80Gbps of throughput, PacketLogic PL10000 is purpose-built with tier one broadband network deployments in mind.

Generally available now, the PacketLogic PL10000 already has four service provider customers from around the world and is currently operating in production networks, said to include at least one of the largest three U.S. cable networks.

Procera Networks systems are used by universities and colleges to manage recreational Internet use at times of peak load, prioritizing academic applications. Some university users say compliance with copyright laws is another reason the Procera Networks solution makes sense.

There's a broader issue here. The Procera approach is in line with thinking that it is not enough to prioritize broad classes of applications. According to a developing line of thinking, service providers need to categorize and control specific applications and specific Web sites, or possibly specific users at specific times of day, not simply "real time" traffic or "email" or "file transfers.

That of course will strike some observers as a dangerous violation of historic Internet "anybody can connect to anybody" norms. But the Internet is changing, not least because users want high-quality voice, video and audio performance, and packet classification is a major tool to allow that sort of choice.

There are, to be sure, anti-competitive implications if an access provider wants to behave that way. One has to assume market forces and governmental action will dampen those impulses.

No doubt about it: the Internet is changing.
