What are the biggest trends and challenges that will face corporate network managers in 2007 when it comes to purchasing Internet services? I asked two experts – DNS inventor and Nominum Chairman Paul Mockapetris and Savvis CTO Bryan Doerr – and here is what they had to say.

Q. What are the top trends for 2007?

A. Both Mockapetris and Doerr predict the availability of new and better services from carriers in 2007.

Mockapetris says service providers are more focused on the quality of the services they provide, particularly when it comes to the performance of applications over the Internet.

“We see carriers more focused on making sure that applications work, rather than providing raw bandwidth,” Mockapetris says. He predicts quality will improve for both broadband and wireless services, and he says customers will pay more for higher quality DSL, cable and WiMAX services.

Doerr predicts the release of new application-aware hybrid and managed services.

“The network is getting intelligent again,” Doerr says. “The network is becoming embedded in terms of application awareness. Service providers can monitor what is happening in the network and adjust it to obtain end-to-end application performance instead of having the user’s quality of service dictated by the available bandwidth.”

Mockapetris says innovation will come in small packages in 2007.

“Little services are the trend for 2007, like mashups that put information on a map,” he says. “These are little things that tie all of the technology together, but they will have big significance for end users.”

Q. What are the biggest worries about the state of the Internet infrastructure?

A: For Doerr, the biggest worry is the glut of network capacity and its continued impact on the health of the service provider marketplace.

“If [network capacity] doesn’t embed more intelligence, it can be perceived as a commodity,” Doerr says. “Service providers are still under pressure to provide more capacity at ever-shrinking prices.”

That’s why Doerr says managed service providers will be stronger and financially healthier in 2007.

“With managed services, commodity pricing is less of a concern because you are managing the edge of the network and controlling the complexity of the network for the customer,” Doerr says.
