In case there was any confusion: I do not, do not speak for my employer or anyone else. So there.

“ What’s important here: CloudFront dynamic acceleration costs the same as static delivery. For US delivery, that starts at about $0.12/GB and goes down to below $0.02/GB for high volumes. That’s easily somewhere between one-half and one-tenth of the going rate for dynamic delivery. The delta is even greater if you look at a dynamic product like Akamai WAA (or its next generation, Terra Alta), where enterprise applications that might do all of a TB of delivery a month typically cost $6000 per app per month — whereas a TB of CloudFront delivery is $120. Akamai is pushing the envelope forward in feature development, and arguably those price points are so divergent that you’re talking about different markets, but low price points also expand a market to where lots of people can decide to do things, because it’s a totally different level of decision — to an enterprise, at that kind of price point, it might as well be free. „
“ Does that mean that EVB, TRILL, and other similar technologies have no future? Absolutely not. Networking industry made tons of money deploying RSRB, DLSw and CIPs in SNA environments years after it was evident TCP/IP-based solutions (mostly based on Unix-based minicomputers) offer more flexible services for way lower price. Why should it be any different this time? „
“ Current network management platform strategies, as typified by HP OpenView platform, have consistently failed to deliver any value to networking. Indeed, any mention of HP OpenView to Network Engineers will result in laughter, outright scorn and horror filled war stories. And yet, OpenView continues to be sold to management & executives. We do need better Network Management tools, but those existing products such as Cisco Prime/CiscoWorks and OpenView are clearly proven to NOT be an answer. „
“ The key to sFlow’s adaptability is that switches export packet headers, leaving it to sFlow analysis software to decode the packet headers and report on traffic, see Choosing an sFlow analyzer. The templates needed to extract tunnel information from packet headers are described in the Internet Drafts and RFCs that define the various tunneling protocols. For example, the following packet diagram from the internet draft VXLAN: A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks describes the fields present in a VxLAN packet header: „
“ The following conclusion to me is incorrect: Google built internal servers and switches and they are using OpenFlow and therefore the companies that build servers and switches will be under enormous pressure from the network DIY movement and most likely will go out of business.
I think the following conclusion is correct: Google built a network that is adaptable to the compute requirements of their business. „
“ Imagine you have this Packet-Tracer functionality NETWORK WIDE – that’s right, network wide. Imagine wanting to test how a change may affect the network campus wide or enterprise or debugging an issue where a packet doesn’t reach its destination. Within a SDN, this becomes possible. This was actually eye opening for me in terms of looking at the product development and testing of software based solutions. His team at Stanford is already well underway on developing these types of tools for the Stanford campus network. Imagine specifying a flow in a simple UI, clicking submit, and the output quickly showing where the dropped packet is in a muilt-node network. The output may show the error is with the ACL on Router 5 port 3. Well, you really don’t have to imagine this because you can go to Stanford and see these types of developments. „
“ This is an area where I think the advent of the programmable server-based controller is a big deal. It changes the customer power dynamic, putting the cloud architects and the programmers in the driver’s seat, effectively placing the network under their control. (Jason Edelman has begun thinking about what the rise of SDN means for the network engineer.) In this model, the network eventually gets subsumed under the broader rubric of computing and becomes just another flexible piece of cloud infrastructure. „
“ After all, value (as in “money that your vendors extract from you”) almost never “magically” disappears from the stack. It simply moves somewhere else, in some cases making you pay more dearly than before. „
At Interop Las Vegas 2012, Dell will demonstrate new SDN-based solutions showcasing the ease with which customers can virtualize their infrastructures and enable multi-platform orchestration and multi-tenancy.
As part of this, Dell also announced interoperability with Big Switch Networks Open SDN ™ architecture. Big Switch Networks delivers cloud networking solutions based on open standards such as OpenFlow, providing customers more networking choices within the SDN ecosystem.
