Although NAT (Network Address Translation) introduces complexity to IP-based system architectures, it has been used for more than 15 years to hide large private networks behind a limited number of public IP addresses. In the long term, IPv6 will provide a quasi-unlimited address space and could lead to a flat IP architecture that would obsolete NATs in certain cases. However, the introduction of IPv6 is a long process and there are some needs for Read More »

Network overlay challenges
Thanks to on-going increases in processor performance, the number of Virtual Machines per server blade is expected to grow rapidly, from typically 20 today to a hundred in 2016. Given this growth, the virtual switch that is present on each server blade will need to distribute significantly increasing volumes of network traffic, becoming a strategic focus for networking equipment suppliers and service providers.

IP Forwarding Characteristics
Wikipedia defines IP Forwarding as follows: “IP forwarding is a process used to determine over which path a packet can be sent. The process uses routing information to make decisions and is designed to send a packet over multiple networks”. While this definition might give the impression that forwarding packets is a straightforward task, achieving high performance on processor-based platform presents significant Read More »

Developers of high-end networking equipment for enterprise, cloud and mobile infrastructure applications are challenged to deliver on-going performance improvements while maintaining small form-factors. A standard Linux networking stack uses services provided by the Operating System and is subject to significant overheads associated with functions such as preemptions, threads, timers and locking. These overheads may be imposed on each packet passing Read More »

Today’s enterprise-class security appliances need to secure and manage hundreds of thousands of connections, within applications such as enterprise and public/private cloud data centers. Advanced security features are required to address the increasing sophistication of threats, requiring ever-increasing levels of security processing within standard equipment form-factors.
The standard Linux OS is inefficient for high-performance security solutions, Read More »
