SDN World Series’ Tim Skinner recently managed to grab a few minutes with Erik Larsson, who is VP of Marketing for DPI & Network Intelligence specialists, Qosmos.
Here, Erik share’s his views on how DPI will help to facilitate Dynamic Service Chaining, seen by many as an early use case of virtualisation networking for service providers.
Erik will be representing Qosmos and speaking at SDN & NFV 2014, Europe’s comprehensive meeting place for the burgeoning telecoms network virtualisation marketplace.

TS: Hi Erik, thanks for taking your time to speak with us. Firstly, are you happy to some detail about your experience in the industry and current role at Qosmos?
EL: I have been working in the networking industry for over 20 years: enterprise networks, cloud services, IP telephony, and the past few years with traffic analysis in the form of Deep Packet Inspection (DPI) with Qosmos.
For anyone out there who’s new to the industry, could you describe what Qosmos do?
Qosmos supplies DPI software to equipment makers and software vendors who embed Qosmos in solutions where real-time service awareness is critical, such as traffic optimization, quality of experience, analytics, cyber security and more. Qosmos software components can be used in all environments – physical, virtualized and in SDN architectures – to shorten product development cycles and ensure continuous signature updates.
Qosmos created this market and are the leading specialist for DPI software components, serving more than 60 companies worldwide. We are based in Paris, with regional hubs in Silicon Valley and Singapore.
What would be the main use case you see for your DPI software?
In telecoms, we see a lot of interest for Dynamic Service Chaining, which is the first use case many service providers want to implement.
Why are service providers so interested in Dynamic Service Chaining?
Today, telecom and cloud traffic is typically pre-programmed to go through a number of service functions (Firewall, NAT, caching, etc.) in a rigid configuration and with significant manual intervention. To increase flexibility, reduce costs, and ease innovation, network operators and cloud service providers are looking for ways to automatically optimize the number and sequence (chain) of service functions needed to process network traffic. In short, they want dynamic service chaining.
To enable this dynamic service chaining, there is a need for detailed, real-time traffic visibility up to layer 7. This can take the form of a DPI module integrated with a virtual switch. The DPI module identifies all protocols and adds service information within the traffic, using principles such as those discussed in the IETF working group on Service Function Chaining (SFC). The DPI module can act as a service classifier for all functions and products (e.g. switches and hosts) able to read service information embedded in the traffic.
How does Qosmos help to enable this Dynamic Service Chaining?
Our new Qosmos Service Aware Module (SAM™) is a DPI module which adds layer 7 intelligence to virtual switches and provides the detailed, real-time traffic intelligence required for dynamic service chaining. The vSwitch combines information from the SAM with policies & rules to dynamically steer traffic to only the relevant L4-7 services, in the right sequence. This means that the sequence and number of services can be optimized dynamically and for service providers, this translates into increased flexibility, better ROI, and facilitated innovation.
Are you happy to share details about some of the projects you are working on at the moment?
Qosmos is actively involved is several PoCs together with our ecosystem partners. I can name a couple of ETSI PoCs, such as the “Virtualized Mobile Network with Integrated DPI”, which we are doing with Telefonica, Intel, HP and others. Another interesting ETSI PoC is the “CloudNFV Open NFV Framework Project”, with Telefonica, Sprint, Metaswitch and others. I am also proud of the “TM Forum’s Most Innovative Catalyst” award we received recently for a demo showing dynamic, data-driven management and operations.
Finally, do you think that Trade Shows play a prominent role in helping the development of the SDN & NFV movement?
Trade shows in general are great places to find out about the latest technical trends and understand in which direction business is evolving. It is a very efficient way to meet a lot of relevant people in a short period of time. Good trade shows accelerate business and technical implementations. This is even more crucial during times of industry-wide market transitions, such as the move toward virtualized networking!
Thanks for sharing your views with us, Erik. We look forward to seeing yourself and Qosmos in Nice in September!
