Medical Edge is a network of healthcare providers
operating principally in the Dallas/Fort Worth area. The group now
includes over 45 healthcare locations and the need for connectivity
between each location and the corporate offices was paramount. Additionally,
connectivity between Medical Edge and its vendors & suppliers
is necessary.
Background
"We needed a secure environment, a high degree
of reliability, fast connections and a support team that would be
there when we needed them," says Chad Hebel, Vice President
of Operations for Medical Edge. "We initially purchased our own
equipment and telecommunications lines and administered the network
ourselves. However, our growth has been phenomenal and with that,
our needs became more complex. At the same time, the range of products
we were providing to our internal 'customers' required more and
more bandwidth. On top of all this, we were being bombarded with
compliance issues as they relate to HIPAA. That's when we decided
to bring in Maxuptime."
"We had actually helped Medical Edge when they
initially installed their network," says Bob Reese. Bob and
his partner, Bruce Goldstein, had a long history working with Medical
Edge. Most of that was as consultants assisting Medical Edge with
their network. Bob continues, "My consulting practice, Robert
Reese & Associates, assisted many companies such as Medical
Edge. As we added telecommunications to our portfolio of services,
we began to approach our consulting customers with these new service
opportunities. It was then that we decided to create a corporate
identity separate from Robert Reese & Associates and that was
when Maxuptime was born."
"We knew their network very well and felt we
could help them achieve the service levels required by using Maxuptime's
MPLS network," adds Bruce Goldstein. "As their needs would
grow, they could upgrade their connectivity without having to invest
in the underlying technology. They would be able to leverage the
investment we made in our network to their advantage."
The Network
Our approach was to copy Medical Edge's existing
network model into our own infrastructure. At the time, this was
easy to do because their network was rather small. They had 3 PRI
circuits for making ISDN connections between the individual offices
and their network. Additionally, they had 2 T1 circuits; one for
backhauling the remote office traffic and the other for internet
connectivity.
The only difference was that because their existing
network was private and ours was public, we had to incorporate a
mechanism for security. We decided to use Multi Protocol Label System
(MPLS) as a virtual platform to ensure the privacy of Medical Edge's
traffic. Briefly, MPLS partitions network routers into multiple
router instances. Each customer gets their own, private virtual
router which makes their traffic invisible to other partitions,
including general internet traffic. The partitions are synchronized
between all routers on the network. Because the partitioning occurs
on the edge of our network, no special equipment is necessary at
the customer's premises.
Bob Reese explains, "We knew the transition
period would be critical because all the Medical Edge healthcare
facilities depend on the network for patient management - in real
time. We couldn't afford any downtime, so we took great pains to
ensure that each office remained connected to the application servers
at Medical Edge's main office. We purchased the necessary telecommunications
line to duplicate the existing infrastructure on our network. We
then began to methodically move each office to the new network,
even work through an entirely unexpected problem. The new ISDN PRI
circuits worked just fine. However, our vendor's switched network
had difficulties in communicating with the ILEC network in some
areas. However, we worked through the vendor difficulties and finally
got the network running.
The network is constructed in the following manner:
The corporate office has a DS3 connecting to Maxuptime's network
as well as a T1 circuit for backup. The DS3 is provisioned into
2 logical circuits using frame relay encapsulation. One logical
circuit is for backhauling all the remote office data and the other
is for internet connectivity. Each remote office connects through
the Maxuptime MPLS network to get to the corporate office network.
Once on that network, they can access the patient management databases
as well as other functions. Remote offices also get connectivity
to the internet through the corporate office internet connection.
A firewall with 6 physical connections is used to
protect all corporate data. In this fashion, we separately manage
Internet traffic, corporate traffic, remote clinic traffic, and
VPN traffic. The corporate office is protected from both internet
intrusions as well as potential difficulty from the remote sites.
Additionally, using 3DES encryption, connections are made over the
internet to many business partners and remote sites connecting from
distant cities.
Since the initial installation, Medical Edge
has upgraded many of their remote connections to ADSL. Some of the
larger sites have T1 connectivity. In the not too distant future,
as more and more services are added to the mix, all of the remote
sites will be upgraded to T1 circuits.
