We’ve packed StingRay 2.6 full of new features and functionality – designed to make the large file transfer process as quick and simple as possible.  Here’s a rundown of the key features built into StingRay 2.6:

Quicksend – An entirely new file sending option, available when sending files via the StingRay Client Application (Mac version 2.0.2).  Aptly named Quicksend, this feature allows internal users to send files/folders quickly and simply in a few short steps.  Just create a new job, add an email address, attach the desired files/folders and press send.  It really is that simple.

Direct Web Browser Upload – External users can now upload files directly into StingRay’s incoming queue via the external web browser interface.  Significant in terms of automation potential, this new feature is ideal for directing incoming files into internal production workflows, freeing staff from manual downloads and allowing them to focus their attention on more productive, revenue generating tasks.

HTTPS – All of StingRay’s file sending options that rely upon HTTP as the fundamental delivery protocol (Email Hyperlink and Web Browser Upload/Download) can now be secured in transit by HTTPS.  The leading security protocol used on the internet today, SSL provides superior levels of security and is the standard implementation when purchasing items online.  Self-assigned SSL certificates can be created within the internal web browser interface or alternatively, if you have an existing SSL certificate, this can be uploaded to the StingRay.

If that wasn’t enough, a number of tweaks and improvements have been made to the existing features provided by Hermstedt StingRay.  These include:

- Personalised Customer Logins (External Web Browser Upload)
- Progress Bar during file upload (External Web Browser Upload)
- Successful Upload Notification (External Web Browser Upload)
- Email Hyperlink Auto-delete functionality
- Hyperlink Signature Customisation potential

If you want more information, you can download a comprehensive guide that outlines the new features in 2.6 in greater detail.

This is the best bit – the StingRay 2.6 upgrade is FREE for all StingRay 2.5 users that hold and valid Silver or Gold maintenance contract.  Just send an email to customerservice (at) pro2col.com and we will get the upgrade process rolling for you.

Unsupported StingRay users and those holding a Bronze maintenance contract will still be able to upgrade if they’d like, all you’ll need to do is contact the Pro2col sales department on 0333 123 1240 for pricing.

For those of us unfamiliar with the term, latency is an expression for the period of time taken to send a data packet from a source to the intended destination.  The higher the latency, the slower the data transmission.  This incorporates all elements involved in the file sending process – including encoding, transmission, and decoding.

There are certain delivery protocols (such as FTP) that are particularly susceptible to latency.  This is because when sending packets of data to a remote site, the sending site waits for an acknowledgment that the packet has been received before sending the next one.  This makes the problem extremely time consuming in the event of high latency.  In extreme cases of latency, the time that it takes for the delivery of data and then the reply, can result in the data throughput levels dropping to a significantly low level, rendering the solution useless.

So, what can we do about it?  There are several ways to combat this problem – one being to utilise a multi-threaded TCP protocol – working in the same manner as above ONLY multiple packet transfer requests are made at any one time, increasing the throughput.  Another increasingly popular route is to adopt a UDP based delivery protocol, which applies a send and forget mentality i.e. they don’t wait for the acknowledgment receipt.  This can significantly speed up the delivery process BUT then you have to consider the fact that other features are required, and UDP out of the box won’t work for everyone.

How can you measure the latency on your connection?  Network tools like ping tests and traceroute measure latency by determining the time it takes a given network packet to travel from source to destination and back, the so-called round-trip time. Round-trip time is not the only way to specify latency, but it is the most common.

To test the latency on your Internet connection between 100’s of test servers you can use a tool like Speedtest.net, where you can test your bandwidth and latency against a local (London) server and say one in Bangkok.

On DSL or cable Internet connections, latencies of less than 100 milliseconds (ms) are typical and less than 25 ms desired. Satellite Internet connections, on the other hand, average 500 ms or higher latency.

So if you suffer from latency problems when it comes to file transfer, please feel free to contact Pro2col to discuss.  Alternatively, you could have a look at the fast file transfer section on our website that details some solutions that may help.
