The Packet Company was founded in 2012 by Dr Andrew Thomson. With over 20 years experience in designing complex systems at that point, and with most of the previous decade spent working in network monitoring and traffic analysis, I had become frustrated with both the cost and level of functionality available in many commercial tools.

After some considered thinking and research I decided to develop my own network recorder, hence the Packet Company was born.....

From the outset, the Packet Company's focus has been to create top-quality solutions to some of the common problems that network and test engineers encounter. In doing so, we have provided our customers with a complementary mix of consultancy, products and bespoke features. A key part of this has been to make products that are open and flexible; this allows users to enhance and extend them, reconfigure them and integrate them with other systems. And it provides a high degree of future-proofing too.

PacketRAID is our first official product - a multi-port, multi-format, multi-rate signal recorder for capturing Ethernet or SDH. It's incredibly flexible, both in the range of signal types and speeds that it can capture and replay, but also the platform itself. We are equally proud of the User Interface we have built. Not only is it beautiful, but it provides our users with an intuitive, informative and easy to use graphical environment - we're understandably very proud of what we have achieved.

Jon has a wealth of knowledge in telecoms signals and protocols.  He has recently been working on the development of PacketProc our new analytic tool.



Please have a look at some of our latest articles.



Our development and test teams have been working hard throughout the Summer and early Autumn to bring us the latest version of the PacketRAID software suite.  Version 3.0 now provides a number of new and enhanced features:

  • Full capture and replay up to 40Gb/s (all packet sizes)

  • Additional recording types: RAW / ERF / PCAP / PCAPng

  • Moloch integration (for deeper analysis)

  • Low order SDH recording, analysis & playback

  • OTU record capability

  • Replay repeat

  • Fully 'built in' online documentation

  • Enhancements to the: User Interface (UI), Fine Grained Security, and also Improved Compliance & Validation


In early January 2019 we will be saying goodbye to our temporary office at the Springbank Community Resource Centre.  We are really looking forward to moving into a fully refurbished office and lab space at Elmbridge Court. Located mid-way between Gloucester and Cheltenham, and within 2 minutes of Junction 11 on the M5 it will be very easily accessible for all of our visitors.  

The new spacious office looks absolutely amazing, and from January onwards we can't wait to welcome both old and new customers. 

So please don't hesitate to give us a call to arrange your visit.

The NEW Packet Company newsletter intriguingly titled the Packet Generation is set to be launched in early January 2019. This is set to be the first edition of our regular quarterly bulletins. Having undertaken some research we have decided to go to a paper based format, a lot of people we’ve spoken to have said they much prefer something physical to browse through. Often electronic newsletters and similar digital format papers just seem to get lost amongst the multitude of emails we seem to receive nowadays.

It’s aimed to be both a light hearted yet informative read. It will be filled with: news features, technical articles, advice & guidance, as well as providing an insight into some of the things that go on behind the scenes at the Packet Company. Plus we will also be running a competition within each edition, with a fantastic prize to be won each time.

If you would like a copy, and have yet to receive one, please call us on: +44 (0)844 310 3330 or alternatively email at


July, August and September have been a pretty busy few months.  Along with the development work on Version 3.0 of PacketRAID, the planning for our move into Elmbridge Court, and creating our first Packet Generation newsletter of 2018/19, we have also produced this new and improved website.

Not only is it now packed with much more information than the previous version, it also features new and improved navigation plus a whole load of new content for you.

The new website will be launched in January 2019. So if you’re reading this shortly after the festivities of Christmas and the New Year, then you are one of our very first visitors. Please stick around over the forthcoming months as we have some fantastic plans for the website.

In this series we’ll be looking at time and time-keeping, and the challenges and opportunities when applied to packet capture and replay.  In this space, accuracy is key - especially when correlating between recordings.  But achieving consistency across multiple pieces of equipment deployed to several sites can be difficult.

We'll attempt to address some of the common problems that occur and look at tested solutions, as well as covering some of the background to explain what is going on.

So let’s start by looking at something very topical, and proving to be quite contentious.



DEC 10, 2015

Bit Rate, Packet Rate and Loading

Some of the most common statistics to see for ethernet are the bit rate for a connection (e.g. 1G, 10G), the packet rate (e.g. 1.8Mpps) and the loading (e.g. 37%). But how are these calculated, and what do they mean in practice?

The bit rate is the logical speed or bandwidth of the link, and indicates the maximum data rate that can be transmitted, including overheads (see below).

The maximum packet rate isn't fixed, but depends on the average packet size, and this in turn depends on the traffic type. For example, VoIP packets tend to be very small, whilst web browsing packets are usually much larger.

Loading describes what proportion of the link's bandwidth is being used, and takes into account the amount required by the packet itself plus ethernet overheads such as preamble and inter-frame gap.

In developing the PacketRAID recorder, The Packet Company invested a considerable amount of time and effort into evaluating different storage configurations. Below, we outline our approach, one of the tools we developed, and the results we achieved.





We are proud of our close relationships with some of the most innovative technology providers in the world. Our aim has always been to be positioned to provide our customers with the best products available within the marketplace. It is important that the products we resell form a complimentary IT Security ecosystem for our clients. Not only is innovation and technical excellence important in our selection criteria, but also ensuring that these partners have sustainable and enduring product roadmaps. It is critical that we provide cohesive and mutually beneficial solutions, however it is equally important that this also presents our valued customers with a long term, value for money capability.

We are always looking to forge new relationships with similarly focussed businesses. So if you are either a product manufacturer or a service provider who you think provides products or technologies which have synergies with us, then please reach out to discuss this in more detail: either phone on +44 (0)844 310 3330 or alternatively email at
