LTE Diaries: GTP Tunneling: The last time I posted to the blog we were talking about questions surrounding IPv6 deployment. You might remember from that post that I am a software architect at BreakingPoint Systems, specializing in design and performance for the network processors in our products. Today I get to continue our "LTE Diaries" series where we have outlined our plans for LTE support and the speed at which we are able to make this happen thanks to the network processor-based architecture. If you haven't read the previous posts I would encourage you to read up on our overall LTE development, the S1AP implementation and our SCTP support. Today we will tackle the GPRS Tunneling Protocol, or GTP. GTP is a layer-4 protocol used for a number of different back-haul tasks in a 3GPP/LTE environment. It comes in two flavors, GTP-C (control plane) and GTP-U (for user data). I have had the opportunity to implement parts of both GTP-C and GTP-U for BreakingPoint's upcoming LTE support, and would like to share some development notes.

The Costly Lessons Learned When Network Traffic Shaping Devices Fail: Often, the most informative blog posts come from our team in the field, which is why I’m writing today. We were engaged in a professional services project recently, when a customer relayed the details of a pricey lesson learned at a large mobile carrier. We are sharing the story in the hope that it might help other organizations avoid this costly mistake.

HTTP DDoS Flood Simulation: The BreakingPoint Storm CTM is a highly effective tool for generating massive amounts of load to test your web services infrastructure. You can leverage this capability to generate both legitimate and nefarious traffic in order to simulate an application layer Denial of Service (DoS) attack. In this blog post, we will step through the generation of a realistic attack scenario which can be used to evaluate your web infrastructure’s resiliency, especially that of DDoS mitigation systems. Also, If you’d like to try this for yourself, simply download the ATI update released today (68714) and open up the tests prefixed "Blog Post 2010-08-20 DDoS".

Why Rethink Dual Stack IPv4/IPv6 Testing?: In order to meet the high expectation of the IPv6 network and service quality, and deal with the reality of dual stack IPv4/IPv6 traffic organizations are looking for an efficient, realistic and scalable tool to measure the impact of dual stack traffic. Their ability to measure the performance, security and stability of any network handling IPv4/IPv6 traffic will directly determine if the launch of any IPv6 based network and service is successful.
