Intel ONS Based Software Defined Network

Wednesday, November 19, 2014 11:27:57 PM Asia/Taipei

In this article we’d like to remind you about the Software Defined Network (SDN) concept and discuss its implementation in the Intel ONS platform.

What is SDN?

There is a lot of information available about SDN, so we will just briefly remind you the basic idea, which is to manage network equipment and data transfers separately.

Here are the benefits of this solution:

  • Direct network programming: The separation of the management planes lets you build your architecture directly.
  • Flexibility: the administrator can adjust the network’s operation rules “on the fly” to adapt to changing requirements.
  • Centralized management: All management options are combined (logically) in a single location, namely in the SDN controller. The network is identified by applications as a single logical switch.
  • Software-based configuring: The SDN concept allows to configure, manage, define security rules and optimize network resources quickly through automated means. You can even develop your own tools for that purpose.

The concept is still controversial, yet we think it is highly perspective.

White box switches: Understanding the basics

Thursday, November 20, 2014 12:03:41 AM Asia/Taipei

White box switches and their associated operating systems are poised to make an impact on the networking industry during 2014.

White box Ethernet switches offer IT the advantages of flexibility, lower Capex and potentially lower operating costs as compared to traditional "black box" Ethernet switch options. White box switch adoption will be led by large cloud/Web-scale operators with a wealth of IT talent.

EDC PHY and PHYless switch design difference

Thursday, November 20, 2014 12:10:35 AM Asia/Taipei

Almost all modern bare metal switches are described as PHYless. What does it mean, what we need to consider?

We commonly interconnect network devices for distances below 100 meters with twisted pair or maybe 300 meters over OM3 multimode fiber for 10GBASE-SR. We can extend the span between devices to 10Km for with 10GBASE-LR, 40Km for 10GBase-ER or even 80Km for 10GBase-ZR. However, the signal path doesn’t end at the transceiver. The electronic engineer designing the circuit board must ensure that the signal received by the transceiver is transmitted to the switch ASIC (and vice versa) while maintaining signal integrity and that it a major challenge. Each of the signals traveling along the copper paths has to deal with hazards like electromagnetic interference (EMI), coupling and crosstalk, signal reflections, impedance mismatches, skew, attenuation and a host of other threats as they travel.
