Q-Balancer

The Q-Balancer uses the DeanSoft operating system and offers the highest standard of performance and reliability. With no moving parts and completely configured in Flash memory hardware failures are a thing of the past! Q-Balancer can be provided in table top or rack-mounted format.

By constantly monitoring all the links being used the Q-Balancer ensures the maximum bandwidth is available to users at all times, outperforming the performance of a typical router which can only handle one link. Q-Balancer copes effortlessly with large file downloads and those web-hosted applications which require 100% reliable connectivity.

Installing your Q-Balancer

Installing your Q-Balancer could not be easier... Your network traffic will flow instantly through your Q-Balancer as soon as it is plugged in – all you need to do is set the balancing rules to match the needs of your system. Our engineers will be happy to support you to ensure you get the best performance from your Q-Balancer for your organisation. Because the Q-Balancer operates independently of any other hardware no special configuration is required on any of the other telecoms and network systems you are operating. Most organisations installing a Q-Balancer will already have an internal network and a single telecoms link. This single (primary) link provides the IP addresses for the firewall/vpn device. The Q-Balancer is transparent to the rest of the network and balances traffic without compromising the performance of the firewall/vpn devices. The Q-Balancer does not require an IP address other than for the management interface.

Using multiple links ensures than an organisation has improved flexibility and reliability. The Q-balancer can maximise your investment by separating traffic onto different links – for example by separating your email traffic from other heavy bandwidth usage to avoid contention across the links both for incoming and outgoing traffic. It will also ensure that if a link fails the services will be seamlessly merged onto the remaining links.

The Q-Balancer also allows management to place limits on bandwidth for specific IP addresses, type of traffic or link.

Configuration

The Q-Balancer uses advanced load balancing algorithms on different protocols to manage traffic across networks. Algorithms can be used both for incoming and outgoing traffic.  Algorithms for load balancing can be applied to entire protocols or specific to source IP/ports. Balancing rules can use different algorithms which include:

• Fast ISP response time
• Redirect to transparent proxy
• Weighted least traffic by packet
• Weighted round robin  IP persistent
• Weighted round robin  by connection
• Weighted round robin  by packet

Managing your Q-Balancer

Managing your Q-Balancer is done using a Windows based graphical management tool.

Any Q-Balancer events and alerts are sent to a remote syslog server on your network through the management interface which also provides statistical data on performance. Email alerts can also be sent if a major incident occurs.

High Availability mode

Robust and flexible, the Q-Balancer integrates real time High availability, allowing the addition of a second load balancer in a fault tolerant configuration. The Link Load Balancer's system and configuration reside in FLASH memory on the device, thereby reducing the risk of failure.
