On data center scale, OpenFlow, and SDN
Lately I’ve been thinking about the potential applicability of OpenFlow to massively scalable data centers. A common building block of a massive cloud data center is a cluster, a grouping of racks and...
View ArticleIncomplete thought: Just in time QoS
Imagine a data center where network QoS is adaptive and self adjusting to the current application conditions. Just in time QoS. Something much different from the static, stale, and generic...
View ArticleNetwork Virtualization is like a big virtual chassis
This is something I’ve been chewing on for a while now and here’s my first rough attempt at writing it down: Network Virtualization is the new chassis switch, only much bigger. (and a lot less...

Embrane came out of secrecy today and announced their solution that virtualizes the deployment of network based services. In the context of how this affects network virtualization, here’s my initial...
View ArticleOn optimizing traffic for network virtualization
The era of network virtualization and software overlays is coming (read: VXLAN, OpenFlow, SDN, etc.) and with it the role of the physical network and what we define as “the network”, is all about to...

I have a hunch. Pure speculation, in fact, that there may be an even more interesting story developing here with the unveiling of networking software startup Nicira Networks. The story being that of...
View ArticleComparing efficiencies of Fixed vs Chassis switches
When building a fabric for a cluster of servers and storage in the data center, how should you architect the network? There are several ways to approach this. The architecture you choose probably...
View ArticleMind blowing L2-L4 Network Virtualization by Midokura MidoNet
Today there seems to be no shortage of SDN start-ups, chasing the OpenFlow hype in one way or another aiming to re-invent the physical network — SDpN (software defined physical network). And then...
