A New Monthly Section
Featuring Hi-Link Senior Engineer Phil
Chen
Q: In the past years, My
Company deployed a gateway for Email SPAM prevention, a
gateway for content filtering and anti-virus, an intrusion
detection gateway, a VPN gateway and a firewall gateway. Some
of the devices are connected inline and some are connected
passively. The task of managing all these different devices is
daunting and the physical network interconnection is complex.
By the way, we are currently looking at spyware prevention
gateway to combat the browser hi-jacking problem. How are
other companies dealing with the complexity of this issue?
A: What you are describing is a problem facing
by many companies today. The industry is moving toward a new
platform called UTM, or Unified Threat Management. UTM is a
maturing technology that combines and unifies all the above
technologies into a single appliance. All big vendors, like
Symantec, Cisco, ISS, and Juniper have a road map for their
next generation of UTM. UTM not only simplifies management of
all these technologies but also makes it much more superior.
It is complicated, and often impossible, to correlate alerts
generated by different devices. By combining all of this into
a single device by the same vendor, correlating alerts and
alarms is easier. The result is fewer false positives and more
accurate alerts. According to IDC, Fortinet is the current
market leader of UTM and commanding 29.5% of the market. They
are the only vendor to use an ASIC, or Application Specific
Integrated Circuitry, in their devices. I expect the UTM
market to really heat up over the next six months with new UTM
products announcement from major security players. You may
want to take a look at them at http://www.fortinet.com or
contact Hi-Link for our bundle solutions.
Q: We have two T1s between our
headquarters and a large remote office. We want to increase
the bandwidth between the two offices. High-speed T3 and ATM
are just prohibitively expensive. Using multiple T1 lines is
plain messy and inefficient. What are my options?
A:
If you have multiple links between two locations, the router
uses load-balancing capability built into layer-3 routing
protocols. You are correct. It is difficult to manage and
inefficient to operate because load balancing takes place on
the network layer. You have two other options. The first
option is to use a hardware inverse multiplexer that combines
the multiple T1s at the physical layer. It load balances the
data on the bit and byte level and it is completely
transparent to your routers. The downside with a hardware
multiplexer is that it is an extra cost item. The second
option is already included with most enterprise router
platforms. You can either use multilink PPP, multilink
frame-relay or inverse multiplex ATM (IMA) to combine the
multiple T1s at the physical layer. It will also efficiently
load shares the data across all links on the bit and byte
level, therefore the technology is very efficient.
