Multi WAN Failover and Internet Link Load Balancing Router
In computing terms, (computing is the activity of developing computer technology, hardware and software which is a specific part of computers and information technology) failover is the ability of the technology to shift automatically to a redundant or a standby system, computer server or a network upon failure of the active application or a network. Failover happens automatically without any human intervention and without any warning or signals.
System designers are those who provide failover capability in servers or networks that require continuous availability and a high level of reliability as well. At a server level, failover automation happens where two servers get connected utilizing a “hearbeat” cable. As far as the regular “pulse” continues to happen with the main server to the second server the second one will not initiate its systems. There might also be a third “spare parts” server that possesses running spare components for moving to avoid the down time.
What essentially happens is that the second server will take charge of the work of the first one as soon as the alteration in the “heartbeat” of the first machine is detected. There are some systems that also have the capability to send a message to a pre-assigned centre.
There are some systems that do not failover intentionally but need human intervention. This “automated with manual approval” configuration operates automatically as soon as failover is approved by a person.
WAN failover is the finest service that functions with multiple WAN boundaries to assure the maintenance of a path to the internet, in case there is a loss of connectivity to one of the WAN connections. For this, multiple WAN connections must be configured before taking advantage of WAN failover’s capabilities.
Usage of WAN Balancer in the network would enable distribution of connectivity across the multiple WAN connections on a regular basis than to maintain a second connection if a failover is required.
Increased Reliability and Network Uptime
WAN Failover provides companies with the facility to avert network downtime that is caused by their Internet Service Provider (ISP). The submission detects if a company's primary Internet link goes down and changes traffic to a backup connection mechanically. WAN Failover identifies the downtime and reroutes the traffic to the rest of the Internet links when it is used with the WAN Balancer.
- Automatically detects Internet outages and switches to the backup provider
- Customize thresholds and tests per connection
- Logs Internet downtime making it easy to identify connections with poor reliability
Now, let us move on to the concept of Dual WAN failover. In case of two WANs what is the meaning of Dual WAN failover?
Communication is the most important part of business and the technology associated with it has transformed to a great extent. The significance of WANs and the Internet cannot be under estimated. Any organization, be it companies or educational institutions to carry out their operations.
The concept of a Dual WAN failover was to have fail over if one Internet Service Provider (ISP) goes down. This is used for its capacity to let dual lines from various providers and types of datalines.
Multi WAN Failover
Multi Wide Area Network are widely used as it has the power to allow multiple lines from various providers and types of data lines based on the speed and availability. In this situation, Multi WAN Failover is an important determining factor to increase business efficiency and provide trust on business continuity.
It is basically a concept that was developed as a result of wide use of Multi WAN connections. In case of a failure, termination of a system or a network module, the subsequent function is routed to a WAN connection that is running. Thus, Multi WAN Failover is the ability to move over to other active WAN lines in case of a failure of any of the WAN lines irrespective of the service provider.
Temporary power cuts bring business operations. Businesses are constantly looking out various options to reduce the effect by making use of various measures that include multi WAN Failover. Therefore, making use of the proper devices that accomplish multi WAN Failover will definitely improve performance. A combination of connections like T3, DSL, T1, ISDN, Cable or multi connectivity is established, and when they face disruptions there is a need for multi WAN Failover.
- Multi WAN Failover helps to continue services over the network at a stretch as fault tolerance is an important constituent in today’s business. Proper direction of the in coming and out going IP traffic to the respective places with reliability and speed is a crucial factor for businesses, even in the occurrence of a failure.
- Multi WAN Failover helps in making the network elastic to breakdowns as well.
- Internet cannot afford to face a downtime as all flourishing businesses are capturing the market by making use of technologies via the internet. If that happens businesses will suffer high level of losses, non-productivity and business continuity also. Thus, large companies make use of multi WAN connections with multi WAN failover to avoid any sort of a disaster. Multi-WAN Failover guarantees continuous uptime and supporting devices.
Not all companies provide unique solutions like FatPipe Networks. FatPipe provides high levels of redundancy, availability for WAN infrastructure and enables maximum bandwidth utilization. Unlike the other companies’ products, FatPipe is different as in it can bond any combination of T3, T1, Cable, ISDN, Wireless connections to gain aggregate speed and redundancy. There are some companies that do not aggregate all of these combinations- it may be only Cable or DSL.
To be more specific, FatPipe’s WARP technology enables Multi WAN Failover. When a failure happens, it very intelligently senses the active link and immediately fails over the active traffic. The set up of the devices is also easy.
This is the uniqueness of FatPipe. Although such devices similar may be available, FatPipe’s fail over is easy to set up.
Yet another feature is that – FatPipe products offer advanced features like load balancing of IP traffic, automatic line failover, site-to-site and unit failover capabilities which increase the WAN efficiency. Multi WAN Failover with the FatPipe products have a very insightful impact on the business continuity of companies as its effect increases speed, redundancy and fault tolerance.
There are market players that provide products for the usage for companies – either small or big or just small or big, but FatPipe differs in this aspect. It provides the information superhighway for businesses and homes that become all the more important.
Load balancing is a concept that refers to the distribution of workload evenly spread over two or more computers, CPUs, network links, hard drives or other resources to get the most advantageous resource utilization, minimize the response time, maximize throughput and avoid an overload. Usage of multiple components with load balancing instead of a single component might increase the reliability through redundancy. This load balancing service is provided by a dedicated program or a hardware device.
Load balancing is of immense use and is of great help in implementing a failover called as a Load balancer failover. It is often a continued service after the failure of one or more of their components. These mechanisms are carefully examined. When one of them becomes non-responsive, the load balancer gets the signal and doesn’t send the traffic. When the component restores on line, the load balancer starts to route the traffic again. In order for this to function, there should be at least one component that is more than the service capacity.
This is supposed to be cost effective than the failover approaches wherein a single live component is grouped with a single “backup” that takes charge in case of a failure.
Uniqueness of Fatpipe’s load balancing failover
There are many market players and competitors that offer load balancing failover.
FatPipe’s difference in technology is that of WARP technology that significantly enhances customer’s aptitude for maintenance of the integrity of their Wide Area Network (WAN). Its features include dynamic load balancing and failover that increase the efficiency of Wide Area Networks. This is where FatPipe differs in that it has its own technology to provide load balancing failover.
Other product features include SmartDNS, Policy Routing and a new load balancing method – the Fastest Route. These features aren’t present in other products offered by leading competitors.
The Policy Routing provides administrators more control over their networks. This way they can define how they would like the data to be transmitted over their networks based on protocol, source and the destination IP address and the destination port as well.
Without the use of FatPipe WARP,
- BGP programming is required
- There is no load balancing for inbound IP traffic
- May be a need to buy additional IP addresses
- Speed of routers from remote locations cannot be scrutinized; on site personnel are needed to implement changes
- There would be a need to purchase software
- There would be no failover/load balancing options
FatPipe’s XTREME is another perfect product technology for companies that require redundancy and dynamic load balancing for outbound Internet traffic. It puts together multiple lines over multiple ISPs without the need for any BGP programming.
This is another important technology which is not provided by any other company. FatPipe’s SUPERSTREAM is another product with almost the same features as the FatPipe XTREME, but in a compact 2 Mbps size- this is another catch as it provides the requirement s for small companies and branch offices as well. It connects to a hub to get together with four connections of any type of media (T1, DSL, Wireless or Cable or ISDN connection).
