Software Architecture

Quality of Service (QoS) is a basic foundation for enabling the “network monetization” that represents such a critical challenge for both service providers and carriers.
Within networking equipment, the first, critical step in the QoS process involves the identification of multiple traffic classes, typically known as traffic classification (and a future post will explain how 6WIND’s software accelerates this function).

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 »

With the widespread industry discussions about Software Defined Networking (SDN) and the OpenFlow protocol, this is an appropriate time to review some of the key SDN performance challenges and how 6WIND’s software addresses them.
Architectural concepts
OpenFlow improves network management by centralizing network control functions and is currently designed to work with Layer 2 and Layer 3 packet forwarding engines.

With this week’s announcement that 6WIND has become a member of the Open Networking Foundation, it’s an appropriate time to explore the critical networking performance challenges that are faced by data center operators and discuss how the 6WINDGate™ software addresses these problems.
The traditional data center networking architecture, which was based on segregated aggregation, access and virtual switch layers, is migrating to a flat networking model 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 »
