Multi-Line WAN Optimization

WAN Optimization has become a consideration in most wide area networks. FatPipe has incorporated several WAN Optimization techniques and made them available as an add-on feature.

WAN REDUNDANCY

A single connection WAN is susceptible to failure leading to non-availability to the WAN. If the single line connection is down, no matter how good acceleration techniques you use, it will be a non-starter. A vital part of multiline WAN Optimization is having multiple connections to the WAN and the ability to failover in case of a line outage. FatPipe technology allows multiple connections to the WAN and thus eliminates unavailability of the WAN due to a single line failure.

DYNAMIC LOAD BALANCING ON MULTIPLE LINES

An essential component of multiline WAN Optimization is FatPipe's dynamic load balancing. FatPipe's dynamic load balancing allows the load to be distributed on WAN connection per a variety of algorithms ranging from simple round robin load balancing to complex load balancing that determines the least number of hops from start to destination.

MULTILINE QUALITY OF SERVICE

FatPipe QoS allows granular control of traffic to the WAN. For example, bandwidth can be reserved for important traffic such as VoIP. This will ensure that VoIP calls will always get priority and have the bandwidth needed for completion of calls. Other traffic would be transmitted on a best effort basis.

DATA COMPRESSION

Data that can be compressed can be transmitted at a far greater rate than uncompressed data. If dynamic load balancing is superimposed on this across multiple lines, then data can be transferred at much faster speeds. FatPipe data compression technology has shown the potential of compressing data by a factor of up to 8.

DE-DUPLICATION

FatPipe's de-duplication technology looks for duplication of data in large datasets and eliminates them. By doing so, data is not transmitted twice and the load on the network is reduced

DYNAMIC TCP CONJESTION CONTROL AND ACCELERATION

TCP acceleration is one of the most important components of WAN Optimization. TCP/IP is sensitive to latency. The higher the latency the slower the transfer of data because TCP assumes the slow acknowledgement of transmitted data by destination is due to congestion and dials back the speed at which it sends data. In networks that have significant latency, data transfer is slow, not because of congestion, but TCP's assumption of congestion.

Several algorithms have been developed to minimize the effect of latency. These algorithms have been developed for various network conditions. Most WAN acceleration technology in the market, that only accelerates a single connection, assumes a static latency and applies a single algorithm. This is fixed. Thus when conditions change, the algorithm may not be optimal.

On the other hand, Multiline WAN Optimization introduced by FatPipe Networks is very different. FatPipe has combined WAN redundancy, load balancing and acceleration into a single device and as a result have a comprehensive solution. This solution ensures that the WAN is always up, loads evenly balanced and most significantly, this technology applies WAN Acceleration algorithms to each line by session. The technology determines the conditions prevailing at the initiation of each session and applies the correct algorithm on each line. This is true multiline WAN Optimization. The rest should be defined as line acceleration.

CACHING

By caching local copies of transmitted data, FatPipe technology reduces the strain on network resources. When changes are made to the original data transmitted, the system only sends the differences.

BENEFITS

HIGH PERFORMANCE

Achieve faster results compared to other WAN Optimization products– FatPipe offers the benefit of storing the data in fast read/write memory as well as on disk, giving bigger storage and better performance.

HIGH COMPRESSION RATIOS

Get an average of eight times compression and up to twenty times compression ratios depending on type of traffic.

IMPROVED BANDWIDTH UTILIZATION

Significantly increase bandwidth utilization of current WAN lines with FatPipe's caching/compression and application acceleration tools.

APPLICATION/DATA INDEPENDENCE

Faster WAN caching than technologies that cache only at the file level – FatPipe provides the benefit of storage at the byte level – no stale data.

REAL TIME CHARTS

FatPipe WAN Optimization comes with a Real Time Chart that provides information about original, un-optimized data per site and statistics after optimization.

WAN OPTIMIZATION WITH WAN REDUNDANCY

FatPipe is the only product that provides WAN Optimization over multiple networks AND the highest level of WAN reliability using FatPipe Router-Clustering technology.

INSTANT IMPLEMENTATION

FatPipe WAN Optimization is transparent and easy to install.

AUTO-SYNCHRONIZATION AND OUT-OF-DATE DATA MANAGEMENT

In a distributed environment between sites, it is likely that data will be lost or corrupted during transmission. With usage of FatPipe's auto-synch technology, you have zero chance of data being out-of-sync corrupted between remote ends.

WORKS WITH SINGLE AND MULTIPLE LINES

Use FatPipe WAN Optimization at locations with single lines, or locations with two or more lines aggregated through a FatPipe router clustering device with WAN Optimization for the ultimate reliable, redundant, efficient, optimized and secure WAN.

FATPIPE LEADING EDGE WAN OPTIMIZATION TECHNOLOGY VERSUS LEGACY WAN OPTIMIZATION

Legacy Systems do optimization on the LAN side and needs multiple devices for algorithm switching. This is a very large drawback because multiple devices are needed if a network has multiple WAN connections. FatPipe leveraging its strengths on the WAN redundancy and reliability router clustering technology has changed WAN Optimization by concentrating on the WAN side. FatPipe does optimization on the WAN side and does session based dynamic algorithm switching on a single device.

Further examples of the suitability of FatPipe's WAN Optimization technology is evidenced in an application involving the back-up of data. In the following example, backing up data using legacy systems requires multiple devices so that various algorithms can be applied to each connection. Since the lines are not aggregated, if a line fails, there will be loss of data because failover is not automatic. However, with FatPipe technology, a single device handles the failover, aggregation and optimization. Automatic failover occurs when a line goes down, thus ensuring no loss of data. In addition, FatPipe WAN Optimization technology is conducted on each session on each line, thus leading to much higher throughputs with an all in one device.
