How to Keep Up With the Rise of Voice, Video and Data

Driven by requirements for greater efficiency and improved constituent services, federal agencies are moving full-speed ahead with voice-, video- and data-intensive applications. The technologies that enable these capabilities, including videoconferencing, Voice over IP (VoIP), and room-based communication and collaboration systems, benefit government in many ways.

Although the benefits are clear, using these applications effectively can require more speed, scalability, flexibility and bandwidth than some agencies currently can deliver. So, agencies are looking for new networking solutions. They include:

Soaring voice, data and video requirements. Doing business today requires almost constant connectivity and the ability to access and share large data, video and audio files. It also requires the ability to collaborate via videoconference and meeting technology. All that takes a lot of bandwidth to ensure smooth uploads and downloads. For example, Microsoft recommends at least 58 KB bitrate upload and download speeds for audio meetings, 2,500 KB upload/4,000 KB download bitrate for video and 2,500 KB upload and download for screen sharing. Without these speeds, traffic can start buffering and possibly even be dropped.

A demand for scalability and flexibility. In the past, network bandwidth requirements were largely stable and
predictable, making it easy for agencies to decide how much capacity they needed to buy. That is no longer the case, as the proliferation of network-based services leads to frequent and unpredictable surges in demand.

Interest in outsourcing. Some agencies, especially the Defense Department (DoD), are looking to outsource circuits and solutions, rather than dedicating so many resources to supporting network equipment. The challenge is doing so without compromising the user experience.

The Solution: Ethernet-Based Networking

The need for scalability, flexibility, adaptability and resiliency will only increase over time, and moving to an Ethernet-based network supports that.

“When you look at the speed associated with TDM, you’re talking about 1.544 megabits for a T1 or 45 megabits for a DS3,” said Greg Bourdelais, DoD Regional Sales Director at Juniper Networks. “Essentially, a 1G Ethernet connection is equivalent to 625 T1 lines.”

Agencies are particularly interested in the idea of the Ethernet Virtual Private Line (EVPL), a service that works
much like TDM, but is powerful, flexible and feature-rich, providing high-capacity, multipoint connectivity. Important
features to look for in an EVPL solution include:
