For this Great Government through Technology Blog post, we welcome special guest author Bill Lewis, the Program Manager for GSA’s Networx program.
Most federal agencies continue to purchase network services through GSA’s Networx telecommunications program. Federal communications purchasing in the first half of FY 2015 shows that Networx continues to be a stable program with steady growth driven by demand for bandwidth. Overall, purchasing for network services on Networx exceeded $820M in the first half of the fiscal year, a 7.6% increase over the same period last year.
Like our last telecommunications insight blog, we wanted to explore and dive into some interesting trends we’ve seen in our Networx program. These purchases–and their associated trends–are also helping us shape the next-generation Enterprise Infrastructure Solutions (EIS) contract, which GSA intends to have ready for government-wide use in 2017.
Internet Protocol Services Sales Dominate
Twenty years ago, more than 70% of federal purchases were voice related — either long distance voice or toll-free services. Unsurprisingly, today less than 10% of the purchases are voice-related services. Most of us have seen this same trend in our personal buying.
Today, the bulk of services purchased are Internet Protocol (IP)-based services. Sixty percent of federal spending on Networx is Network Based IP Virtual Private Networks (NBIPVPN) and management of these services. In the first half of FY2015, NBIPVPN purchasing is up 14% and purchasing services to manage this bandwidth is up 12%.
Purchase trends for various Networx services are shown below.
|Networx Service Type||Purchase Volume (FY15 First Half)||Percentage Change (First Half, FY14-FY15)|
|Network Based IP Virtual Private Network Bandwidth||$391.1M||14%|
|Managed Network Services||$102.0M||12%|
|Toll Free Services||$64.4M||-10%|
|IP Services (External Bandwidth)||$28.5M||8%|
|Long Distance Voice Servies||$19.8M||-6%|
Migration to Ethernet Technology
In terms of networking technologies, federal wireline purchasing is clearly migrating away from the traditional digital signal hierarchy towards native Ethernet.
The bulk of the federal inventory of bandwidth is still around the traditional DS-1, Digital Signal Hierarchy Level 1, which is a 1.5Mbps service. But in the past five years, the number of DS-1s in the federal inventory has shrunk nearly 4% annually. And number of “sub-rate” DS-1s (circuits with less than 1.5Mbps) has shrunk over 6% annually over the same period.
Many of us have more bandwidth going into our homes than a DS-1, so it’s no surprise federal agencies are demanding more bandwidth as well. We rely more on applications stored in remote data centers or the cloud as we use more video, and rely on other services around unified communications.
We’ve seen some migration towards 45Mbps services, a “DS-3”, where growth was up 21% over the past five years. Now the trend is slowing, as evidenced by DS-3 growth only up 8% through the first half of this year. This slowdown is expected since DS-1s and DS-3s are legacy services originally designed for Time Division Multiplexing (TDM) equipment and voice-dominated networks.
Because Ethernet services are designed for networks dominated by IP-based data rather than voice, Ethernet growth is higher as shown below for the past five years.
|Ethernet Purchasing off Networx||5-Year Annual Compound Rate|
|10 Mbps Ethernet||138%|
|100 Mbps Ethernet||78%|
|1 Gbps Ethernet||60%|
Shaping EIS and Preparing for Transition
Networx purchase data has driven some of the requirements for GSA’s EIS contract, which is in its final stages of development. For example, Ethernet will be a required service under EIS. But we haven’t developed EIS requirements in a vacuum by simply looking at historical purchase data.
This spring and summer, we held three information exchange days with industry. These were well-attended, lively events, with over 150 participants in each session. In addition, we have been in frequent contact with government agencies and industry in other forums and individually to shape EIS.
Over the next year, we will go through the acquisition process on EIS. At the same time, we are preparing for the transition from Networx and our regional telecommunications contracts to EIS. As you know, we are extending the Networx contracts three years to 2020 to give agencies time to transition to EIS. Four of the five Networx suppliers have submitted modification extension proposals.
We are also extending many of our local service agreements, including the Washington Interagency Telecommunications Contract 3 (WITS 3), to 2020. We are also working with agencies to develop transition plans and examine inventories of telecommunications services, both essential steps to a timely transition. Agencies will transition all telecom services, including secure Internet and data services as well as voice and toll-free services.
