Quadritek Delivers the Industry's First High Availability
IP Management Solution for Customers Seeking to Build Fault Tolerance
into Their Networks
Allows Companies to Eliminate Single Points of Failure
in Their IP Network Services
Malvern, PA -- March 10, 1997 --
Quadritek Systems, Inc. has announced the delivery of the industry's first high availability
IP management solution. Targeted at customers with TCP/IP networks and Intranets
that require uninterrupted operation, Quadritek's high availability services are
comprised of new architectural features added to QIP(tm) (Quadritek's flagship product),
new extensions added to DHCP (Dynamic Host Configuration Protocol), and the company's
new Dynamic Domain Name Service (DDNS). [For more information, see accompanying
release.] The new features, which are available in the current version of QIP for
Windows NT, provide companies with the ability to build redundancy and fail-safe
uninterruptability into their network infrastructures.
"Companies competing in today's fast-paced, electronic market need networks
that provide uninterrupted service to their users. We have a mandate to provide
our customers with IP management solutions that offer the greatest degree of fault-tolerance
available," said Keith Larson, executive vice president. " Quadritek
defines high availability in three ways:
- Fault Tolerant Infrastructure Design-- If a portion of the network
fails, other components should continue to function;
- Optimized Access
for Users -- The network infrastructure should provide the means to allow quick
and easy access to users; and
- Low-Overhead IP Management -- The network
should work efficiently to minimize the overhead required for administration and
maximize the resources available for users.
Quadritek's high availability IP management solution includes all these features.
With today's announcement, the company rolls out the following:
- New Fault Tolerant QIP Architecture:
-
Support for Autonomous Components -- While they operate interdependently,
all the components of QIP (DHCP, DNS, the QIP Enterprise Server, BOOTP, etc.) are
self-contained and can function independently. Should one service go down, other
services will continue to function.
- Infrastructure Redundancy --
QIP is the only IP management system on the market that allows users to build redundancy
into their IP infrastructure. QIP is architected in a way that provides users with
the flexibility to set up network services (DHCP, DNS, DDNS, etc.) on separate hosts.
A single host can represent multiple primary and secondary servers simultaneously.
This allows network administrators to set up redundant services to act as back-ups.
- QIP
Features that Optimize Access for Users
Automatic Updates for
Primary and Secondary DNS Servers -- QIP automatically updates both primary
and secondary DDNS/DNS servers, guaranteeing that up-to-date address information
is always available and assuring optimized access for users across the network. The
automatic updates to DNS servers occur in multiple ways:
- Dynamic Updates
of Static Objects-- When an administrator issues a move, add, or change for
a static IP address, the QIP Enterprise Server sends an immediate update notifying
all primary and secondary DNS servers.
- Automatic Incremental Updates --
QIP's extended DHCP sends incremental (real-time) updates of new address allocations
to all primary and secondary DNS servers.
- Automatic Periodic Updates
-- The QIP Enterprise Server also sends periodic (scheduled or on demand) updates
to primary servers which, in turn, automatically update secondary servers, including
secondary servers in domains and networks not managed by QIP.
-
Real-Time Updates of Static Addresses -- When new objects (servers, routers,
etc.) are added to the network, QIP updates DNS servers dynamically. This allows
users on the network to have immediate access to new services, rather than forcing
them to wait for a scheduled update of a DNS server. In the case where a particular
service is acting as a back-up and the main service fails, a network administrator
would be able to provide access to the back-up service with little or no interruption
to users.
- Multi-Threaded Processing Capabilities -- Quadritek's
DHCP service has been enhanced to allow it to handle multiple IP address requests
simultaneously. Other implementations handle such requests sequentially, posing
delays for network access or access denials due to time-outs.
- Multi-Threaded
Updating Capabilities -- As soon as an address is allocated to a user or device,
QIP's DHCP server simultaneously sends out an update message to multiple servers
on the network, including the QIP Enterprise Server and any DNS servers that have
authority for that particular domain. These real time updates guarantee that multiple
components on the network have new address information immediately. Should one service
go down, other services will retain the current information.
- Low-Overhead
IP Management
- Automatic Server Synchronization -- When
service is restored to a failed DHCP, DNS, or the QIP Enterprise server, it is automatically
synchronized with other services on the network. Periodic and regular service synchronization
can also be scheduled to occur automatically between the DHCP server and the QIP
Enterprise server, and between the QIP database and the DNS servers. While this
regular maintenance assures that the state of the network stays current, it does
so with little overhead. Quadritek designed its synchronization capability to handle
change management. QIP takes advantage of exception handling techniques to synchronize
network services. This keeps network traffic to a minimum, and leaves more bandwidth
for users.
With QIP, users can build networks that have redundancy and fault tolerance. Other
solutions on the market today have limitations that prevent this. Because these
systems are not set up to support enterprise infrastructures, they suffer from designs
that leave customers with single points of failure. This presents a real problem
for organizations that depend on their network for their strategic business edge.
With Quadritek's implementation of high availability IP management services, customers
have a solution for guaranteed network accessibility.
