scalable data networking services. The company owns and operates a
fiber-optic backbone to serve major metropolitan markets across the
United States and internationally. Veroxity’s services include: Ethernet
Private Line, Flexible Any-to-Any Ethernet, Dedicated Private Line,
Wavelength, Managed SONET Ring, and Internet Connectivity.
Veroxity’s clients include many financial, healthcare, and technology
companies. The company differentiates itself with its customized
approach to developing and delivering data connectivity solutions, its
rapid response to customer requests with direct access to the
engineers who develop and install service, its unique fiber footprint,
dynamic bandwidth reprovisioning, and a willingness to build that is
unique to the telecommunications industry.
Recently the company has witnessed a demand for higher bandwidth
services due to wider deployments of collaboration, video
conferencing, and cloud-based applications. There are also more
requests for Ethernet handoffs to eliminate the complexity of WAN
interfaces, freeing up IT resources and bringing increased productivity
to the enterprise.
Historically there has been a large demand for traditional time-division
multiplexing (TDM)-based services, in part because of the ease of obtaining building access. Although Veroxity’s
existing network was well suited for service delivery of TDM circuits, TDM-based interfaces have historically been
more expensive. With a greater emphasis on simplicity, service transparency, and network control customers are
turning towards Ethernet connections. For this reason, Veroxity required a solution that could increase customer
bandwidth rates, connect geographically dispersed customer sites quickly, and all without increasing operational
expenses. The result is a new Carrier Ethernet-based service offering called “Flexible Any-to-Any Ethernet.”
Network Solution
Veroxity has built a reputation for extremely high levels of reliability; in each metro market, Veroxity deploys network
equipment in two separate “MegaPOP” facilities with redundant hardware components and dual points of building
entry. Metro markets are connected via multiple wavelengths and dark fiber utilizing geo-diverse routes. Different
conduits are used (telecom and power) along with dual points-of-entry into customer buildings. This arrangement
helps ensure the highest level of service availability. Any single failure, whether an equipment problem, power loss to
a building, or a fiber cut, does not affect customer traffic.
Connections to off-net buildings had previously been delivered using SONET-based solutions, even for Ethernet
services, because that technology had not matured to the same level of resilience. However, with the development of
Resilient Ethernet Protocol it is now possible to have a Layer 2 service with SONET-like diversity and protection. That

Customer Case Study
an all-Ethernet network could emulate a SONET network in terms of service delivery yet with lower cost and
complexity makes it a powerful solution.
After careful analysis, Veroxity has upgraded three areas of its network in order to deploy its new “Flexible Any-toAny Ethernet” offering:
Core: The existing carrier-class Multiprotocol Label Switching (MPLS) core was upgraded to support Virtual
Private LAN Services (VPLS) using Cisco 7600 Series Routers in primary network locations.
Metro Aggregation: ME3400E Carrier Ethernet switches were deployed for metro aggregation in smaller
points of presence (POPs). This deployment facilitates the transition from Ethernet over SONET to a pure
Ethernet network.
Customer Premise / Last Mile: Ethernet-over-TDM multiplexers are used to connect customers to Veroxity’s
Points-of-Presence. For the customer premise, the company no longer uses an expensive SONET
multiplexer. A low-cost single rack-unit, wall-mounted, AC-powered Ethernet-over-TDM system provides the
Ethernet hand-off. If the building is off-net, DS3 modules are used to connect to a second Ethernet-over-TDM
mux that connects to the Metro Aggregation network.
“The converged network gives our customers the simplified, agile
solution they demand: Ethernet for flexibility and lower cost, off-net
connectivity for reach, and Resilient Ethernet Protocol for uptime.”
—Chris Williams, Director of Technology, Veroxity Technology Partners
Veroxity has deployed its “Flexible Any-to-Any” Metro Ethernet solution in several cities in the Northeast, with
deployments on the West Coast to begin soon. Veroxity easily accomplished the installation, with some technical
assistance from Cisco Advanced Services.
The deployment has been a major success. The first new connections were turned up on the first try, under budget,
and ahead of schedule. The low-latency, low-jitter L2VPN connections have proven to be a hit with customers using
video conferencing and other delay-sensitive applications.
As an added bonus, Veroxity is also using less power and reducing its carbon footprint.
As a result of the upgraded network, Veroxity can now offer the high-bandwidth Ethernet connections that its
customers have requested. Chris Williams, director of technology, says, “The return on our investment has been
immediate; our customers are very pleased with our ability to easily add new locations.” Like most service providers,
Veroxity maintained a list of building locations that were connected via its own network and therefore the most
accessible. With the new network, Williams is proud to say that they can now “shred the building list” and smoothly
connect almost any location. “The Cisco solution has given us a platform for our network that gives our customers the
services that they want, where they want them, and all while keeping our operating costs very competitive.“
