IPCC Talks VoIP in Two-Part Track

The International Packet Communications Consortium (IPCC) is hosting two sessions today, The Next Generation of Interconnection and OSS for Next-Generation Networks.

Michael Khalilian, chairman and president of IPCC, will host the first session. Michael Tribolet, executive vice president of operations for Vonage Holdings; Cathy Martine, senior vice president of Internet telephony for AT&T Corp.; and Dennis Kyle, vice president of wholesale voice services, Level 3 Communications, are the scheduled speakers.

Khalilian plans to examine the issue from two sides: the first, from a service and network management perspective; and the second, from the point of view of the applications, services and interconnection of networks. It will be an analysis of service provider versus vendor experiences, he says, noting that, since CompTel/ASCENT attendees tend to lean toward traditional wholesale and local traffic, the IPCC is trying to educate people that convergence has started for packet telephony. Khalilian will give some examples of that convergence, as well as outline advantages and challenges.

It doesnt matter what we think about this new technology, Khalilian says. Every new technology has its challenges, and the point is, we cannot go backward anymore. So we have to solve and resolve the challenges and also, by solving them, were going to have other challenges coming. But at the same time, were going to be benefiting from the efficiency and the service of … packet telephony.

Khalilian says the IPCC is working to bridge the gap among service providers, regulators and vendors. The objective is to push the technology and deployment fast…but to do that we have to understand the integration issues. We need to understand some of the challenges that service providers face. We are trying to focus on those challenges by designing the working groups in IPCC around those challenges and [coming] up with recommendations to the industry.

Dr. Hanafy Meleis, vice chairman and treasurer of IPCC, will lead the second track. Harald Braun, president of the carrier division for Siemens; Robert Maher, CTO of Netrake; Andy Ory, president of Acme Packet; and Raj Sharma, founder and president of NexTone, are slated on that panel.

Khalilian explains that session will address service management and session border control. With that in mind, IPCCs Meleis says VoIP providers face two main challenges. The first is the merging of circuit-switched and packet-based technologies, which creates the need for interoperability and managing the service end-to-end across two different technologies with completely different quality of service concepts (QoS), he says. The second challenge is maintaining end-to-end QoS. Meleis says that entails meeting four criteria: assuring end-to-end network performance; monitoring performance of IP-based networks and services; defining both customer QoS requirements and service provider QoS offerings; and ensuring the target QoS end-to-end across service providers and networks.

The panel will address these challenges and more. Meleis says various solutions come immediately to mind. Carriers can emulate the circuit switch by ensuring that the resources for a given session are available and reserved, he says. They can also use different classes of the traffic and give priority to the real-time traffic such as voice.

Overall, Meleis hopes the audience leaves the session with the knowledge that delivering quality VoIP services that drive profitable revenue requires more than technology. Service providers must have the tools to manage the services and maximize the utilization of their infrastructure, he says.
