The StoneFly Company recently introduced StoneWAN appliance. A bandwidth accelerator that uses innovative technology to accelerate data transmission 100 times faster. This innovative approach is designed for businesses that have multiple branches geographically scatter and rely on their data transmission on high bandwidth, high latency networks.StoneWAN is a creative solution for long-fat networks.
Before we dive into the StoneWAN module, let me shed some light on LFNs and why is their latency in a network.
Long Fat Network
Increased Bandwidth does not Equate Increased Throughput
Consider a business with a setup of multiple branches at geographically separate locations. The transfer of data between these branches makes use of a WAN network. This network creates congestion with massive pieces of data. Considering this, bandwidth throttling the problem continues so that the organization decides to expand its bandwidth. It reduces all previous bottlenecks but does not increase the rate of data transfer. That’s because increasing bandwidth is not the same as obtaining latency. By simply increasing the bandwidth, the enterprise ends up with a Long Fat Network.
For example, if the water is the data, and the pipe is the bandwidth, then the company simply increased the pipe capacity. It has done nothing to water speed The only thing that did was make water flow smoother.
Where does latency come from WAN Network?
Latency is caused by our dependence on very effective but very old protocols that have been developed for various applications and use. The delay at the question is caused by the TCP or Transmission Control Protocol. It is a traditional transportation protocol on which most internet is based.
TCP offers various mechanisms enabling effective control of packet movement across a network. For example, it enables network administrators to realize where and when to retransmit data packets are misplaced.TCP can also identify when the network gets congested and needs to throttle the bandwidth. TCP essentially delivers a range of services that are necessary. To do this the sender must receive from the receiver an acknowledgment packet or ACK packet.
This ACK packet is the culprit which causes the WAN networks to experience latency. In a larger network, as the duration of the round trip rises, the rate of data transfer over a TCP reduces.TCP still awaits the ACK packet and restricts the flow of data. This is why you get less performance and feel lag even at a larger bandwidth.
StoneWAN: Efficient and Secure Bandwidth Accelerator
StoneWAN provides enterprise-level services to ensure higher rates of data transfer between geographically separate branches. It runs on network layer 2. Consider a setup of two branch offices and their gateways respectively. The software-defined (SD) WAN connects at each side behind the router. This suggests that the SD-WAN is configured on both sides between the gateway and the machines.
Its setup allows it to be integrated without delay or discontinuation into any existing branch office and without changing the existing network configuration.
StoneWAN performs data transfer acceleration in a two-fold process:
- Dynamic Deduplication.
On every packet received at the appliance, StoneWAN performs compression and dynamic deduplication.
This TCP packet is first compressed and deduced, reducing the packet size by a considerable amount. The packet deduces will then be sent over the network. This runs even quicker than its first equivalent because it has been reduced in size.
Data compression techniques, the multi-branch enterprise gains:
- Enhanced Data Transfer speed.
- Optimized Bandwidth Utilization.
- Reduced cost implications due to effective bandwidth utilization.
Software-defined WAN and Physical Appliance
StoneFly’s StoneWAN is accessible as a software-defined WAN and you can also get a physical device that can be built into your setup.
