Giving YouTube its due

Today, limited end-to-end bandwidth hangs up high quality video streaming, particularly for households. Fatter pipes in the last mile are one solution, but establishing quality of service across the public Internet would allow users to do more with less bandwidth by giving priority to those voice and video packets. QoS across the Internet is not ready yet, but it's inevitable, says Tony Hurtado, vice president of marketing at Masergy, a vendor of MPLS network services for businesses.
"Ultimately you’re going to see QoS be part of the public internet," he says. Two things are holding up the process: legacy network equipment and standards for handing off QoS information between carriers. "I think you will see quality of service on the public internet, partially because you have the networks all moving toward the capability of delivering application-aware networking," he says.
The seeds of that change, he says, have been sown in the rapid expansion of more modern networks that use technologies like MPLS. As those networks interconnect, the public Internet traffic that travels across them will have the potential to include QoS - if everyone can agree to a standard for handing off the information.
The standards process is moving very slowly right now because there's no pressure yet, Hurtado says. "There’s not a driving demand for it right now because so much of the network is older technology."
