RESEARCH 》 Optimization of network data (WAN Optimization) at various levels

WAN Network data can be optimized at various levels depending upon the network applications, protocols, topology and use-cases. So the amount of data you can optimize will depend on the strategy you choose to optimize.

Network Packet level optimization: You can optimize your network data down to individual packets. This may be useful to optimize discrete network data such as VoIP and streaming networking applications. So depending on your network you can do frame level optimization in case if it is a Layer-2 switched network something like MPLS/VPLS scenarios. And in case it is a IP based routed networks you can do IP packet level optimization. So that the IP-header is intact where-as its other protocol headers and the payload is optimized. Hence packet level optimization suits for discrete network data and corresponding network applications.

Session level optimization: Session level (or session based) optimization is suited for complete/full sessions bound by a network connection. For example TCP-connection. A remote MySQL or Oracle database access involves a TCP-connection (or a session). So in this case we are not talking about discrete packet level access (although a session will always comprise multiple packet transfers to and fro) and we are not talking about individual file-level access, instead it is a session-level bulk data transfers. In this case we can employ different network optimization strategy so that the entire session can be optimized.

File level optimization: Last but not least a file-level optimization involves a typical file-download/file-upload scenario such as HTTP, FTP and so on. In this case in general even before sending across the wire we can do lossy (and lossless) compression of these files depending on its contents. But when it is being transferred across the network we can employ a network optimization strategy where an entire file transfer is optimized. We can also implement both above discussed techniques such as network packet-level and session-level to optimize file-level network data transfer. Some of the examples which comes in this category are CDN networks, HTTP Cache Proxy (such as Squid-Cache) and so on.

Case study :: Dolby Servers in movie theaters: Movie theaters these days get digitized extremely high-quality movie files from film producers/distributor channels. Since these files are so huge they are transferred via high-speed wire (fibre-optic) networks. But in case if the movie theaters lack high-speed network connectivity then they ship these movie copies on a regular computer hard-drive. This is a good case study and use-case where file-level network data optimization can be deployed.
Here are some interesting videos on Digital Cinema movie servers and projection technology:

Here is my detailed video of the same:

In case if you are having a company and if you are looking for ways to optimize your network, performance tune-up and or building network optimization product(s) (which may or may not include porting/integrating TOFFEE on to your product), in that case I can offer my technical consultation services. If you are interested you can contact me for the same.

TOFFEE-Mocha WAN Emulation software development - Update: 17-June-2016 ↗
Saturday' 13-Mar-2021
Now I supported and finished complete GUI support of these parameters so that you can configure, store, reboot and the same will restore upon reboot. Besides I complete the TOFFEE-Mocha Big-Picture page. The Big picture is an interface where you can find all the configuration (or settings) of the TOFFEE-Mocha. This is almost similar to CISCO device show all command but in graphical representation. Sometimes a network admin can also print the Big Picture page and paste it near to the device to refer its settings.

Live demo - Data Transfer - High bandwidth to Low bandwidth ↗
Saturday' 13-Mar-2021
I always wanted to do some real experiments and research on packet flow patterns from High-bandwidth to Low-bandwidth networks via networking devices. This is something can be analyzed via capturing Network stack buffer data and other parameters, bench-marking, and so on. But eventually the data-transfer nature and other aspects is often contaminated due to the underlying OS and the way Network stack is implemented. So to understand the nature of packet flow from Higher to Lower bandwidth and vice-versa such as Lower to higher bandwidth, I thought I experiment with various tools and things which physically we can observe this phenomena.

TOFFEE (and TOFFEE-DataCenter) deployment with VPN devices ↗
Saturday' 13-Mar-2021
In case if you need to deploy TOFFEE along with your existing VPN devices you can deploy the same as shown below. This will allow your VPN devices to encrypt your TOFFEE WAN Optimized network data. NOTE: Make sure about the VPN deployment topology done in the right order. Else TOFFEE (LAN side) may get VPN encrypted packets which may not be possible (and or difficult) to further optimize. Hence always make sure to deploy them in a topology suggested below so that TOFFEE devices are out of VPN tunnel.

I was doing some specific tests in my TOFFEE and TOFFEE-DataCenter (WAN optimization) scenarios such as variable upload and download speeds. And I was also doing some experiments with and I did some of these tests with TOFFEE-Mocha. I realized there is a case that I can introduce asymmetric constant delays so that you can get different download speed and a different upload speed. And in some cases much faster download speeds and relatively slower upload speeds.

TOFFEE hardware selection guide ↗
Saturday' 13-Mar-2021
When you build a WAN Optimization device with TOFFEE the entire packet processing (data optimization) takes place in software layer or in other words more precisely Operating System kernel space. However if you have any compression or encryption hardware accelerator hardware card the parts of the TOFFEE packet processing modules can be offloaded to hardware layer and thus improving its efficiency.
