Today, there are principles of no restrictions by Service Providers and BSP on the internet to support content, web page, platform services and other modes of communication.
In order to address this issue, let’s examine a bit of history.
The Pacific Telegraph Act of 1860 called for the simplest net neutrality scheme: All messages — in this case, telegrams — had the same characteristics. All messages were to be treated equally. There was the simplest possible traffic management (FIFO), and this simple traffic policy prioritized government messages. All these features were approved in Chapter 137 US. Statutes by the 36th Congress.
Now it’s 150 years later.
The Internet is perceived as “neutral” – a fundamental right of every person on the planet. Traffic management exists to manage limitations in capacity and different services through quality of service (QoS) and multiprotocol label switching (MPLS).
The question now becomes: Should all IP packets be treated equally?
This is a difficult and important question that is sparking debate across the entire industry.
Telecommunications law specifies distributing, preventing, restricting or delaying the transmission or delivery of a telecommunication message as a criminal offense. It’s punishable by up to three years imprisonment (although it is rarely implemented if at all).
Early disruptions of that model included attempts by some mobile service providers to block voice-over-IP (VoIP) traffic on mobile broadband networks (as it did for wire line networks). This attempt was rejected by regulators and the FCC faster than a speeding bullet.
Telecom laws were amended last year to allow principles of net neutrality, subject to fair and efficient traffic management. The regulator may now decide which traffic management practices are deemed “fair and efficient”. In the United States, the top two carriers have appealed this decision and it is still being worked out. Meanwhile, the Internet continues to improve.
So, what does limited capacity mean? Simply put:
- Bandwidth limitation, latency, jitter, packet loss
- Temporary Congestion especially as HDTV and 3D technologies spread on the internet
Mobile Broadband networks are more vulnerable to this limited capacity and lack of spectrum.
What services are most sensitive to limited capacity?
- VoIP Telephony
- Video Conferencing
- Gaming Applications
- Streaming Video (which will truly take off in 2014)
- Cloud Services – although the jury is out on the impact this will have on the network
Other services are less sensitive to fluctuations in capacity:
- File Transfer/Sharing
- Social Networks
- Normal Browsing
There is currently a huge conflict of interest when it comes to net neutrality, from small players to big players. Net neutrality has many advantages but raises some major concerns as well. Let me explain the benefits of net neutrality for the consumer and society as a whole:
- Helps encourage the free flow of ideas and content
- Provides access to a wide variety of services
- Provides access for the development of new services
- Offers incentive to develop new services
- Offers free choice for customers
The big carriers have countervailing concerns. They worry about:
- Providing good services
- Becoming just a dumb pipe
- Reduced income from value added services (VAS)
- Reduced return on investment; and
- Losing captive customers
Let me provide some policy alternatives — ideas that might make everyone in the industry and the world happier about the future use of IP.
Alternative 1:
- Pros:
- Simple traffic management
- No ground for claims from service providers
- Simple regulation
- Cons:
- Unacceptable degradation of real time services
- Damper on competition
- Inefficient usage of bandwidth
- Unreliable QoS
Alternative 2:
In this alternative, we modify our approach to traffic — and policy — to support everyone, including consumers and businesses:
- Real time services (RTS) would be prioritized over non-RTS
- Critical services prioritized over non-critical services
- Low bit rate services (e.g., voice) prioritized over high bit rate services
- Packets of comparable services are treated equally.
So, now let’s look at pros and cons of this alternative:
- Pros:
- Promotes system efficiency
- Provides benefits to consumers and service providers
- Leaves lots of room for competition
- Provides an incentive for innovation in services
- Cons:
- There will inevitably be debates over what fairness means
- This alternative will require management by complex hardware and software
Leaving aside the hardware/software management question, how can this approach make everyone happy?
Ideally, we would like to make individual users (whether consumers or providers) better off without making any other individual worse. But in a real world setting, making individual users better off without making any other individual considerably worse off is an acceptable compromise.
There is room for everyone in the network and we should spend our energy on innovations to the network rather than endless debates on an issue which most likely will not even exist in ten years.
So, if the FCC and others in the industry agree on either alternative, how does it get implemented? This is a big question. Here are some of the challenges we face:
- How do we make RTS users much better off by making non-RTS users a little bit — but almost negligibly — worse off?
- How do we develop more in-house services versus competitor’s services?
- How do we eliminate the “not-invented-here” attitude in companies?
- How do we [discourage] anti-competitive practices?
- How do we block or bar service-degrading techniques that already exist?
- How do we implement deep packet inspection without violating user privacy?
- How do we [watch carefully for handset and its applications on the network] similar to what happened in the case of the iphone?
I am proposing transparency instead of regulation for the Internet we all love and hold dear. History demonstrates that the Internet will improve over time, adding new helpful services and spurring investment. The economic growth spurred by Internet technology would create jobs in the United States and worldwide, and would have a positive effect on many deficit challenges faced by world governments. Even though I’m not a politician — just a scientist — that providing credible comparable information about broadband service provider traffic management policy will better serve end-users than more regulation.
In essence, let’s not apply the policies of the 20th century to the technologies of the 21st. I believe that the rate of innovation will be inversely proportional to rate of regulation in our new century, and that includes broadband wireless service.
Now, I can predict the counter-argument: “Has the common customer enough know-how to make use of such complex technical information?” My answer would be yes — over time, they would. This would require aggressive education on the technologies beginning in the K-12 years.
I predicted almost over a decade ago that IP-MPLS will eat everything and that broadband wireless will eventually eat IP. There is no question that this prediction has come true.
Here are some points I would like policy makers and service providers to consider:
- Move to all-IP networks and retire all public switched telephone network legacy services
- LTE-A will finally push mobile broadband ahead of fixed broadband by 2015 or perhaps sooner
- LTE allows the coexistence of voice, video and data in the same mobile broadband network
- Traffic Management is essential for QoS even for in-house services
In the final analysis, traffic management is a must. It’s non-negotiable. A policy of optimized and fair traffic management it must be established in policy and in the law — especially in the regulation or licensing of ISPs and BSPs.
