A recent post from Ivan Pepelnjak entitled Revisited: The Need For Stretched VLANs
made me smile rather bitterly as Ivan dug into the apparent continued desire for stretched layer 2 networks and the reasons
people give for the solution’s requirement and validity. I love a good bit of snark as much as the next nerd, so as you can imagine, I’m all over that post.

However, I confess I did wince slightly – in the way one might do when an old wound is poked with a sharp stick – as Ivan made a passing sarcastic reference to Microsoft’s amazing Network Load Balancing technology:
My mind was thrown back to the heady days of 2009 when I stumbled across another post from Mr Pepelnjak, this time entitled Turn a switch into a hub … the Microsoft Way
which bemoaned the unadulterated stupidity of Microsoft’s attempt to use layer 2 network flooding to accomplish clustering. I had discovered the nature of this behavior at a previous client and had my mind blown by the very stupid and non-standards-compliant way in which this had been implemented.
The reason my mind went to that post, however, is because if I recall correctly it’s Continue reading
Broadcom, to much fanfare, has announced a new open source API that can be used to program and manage their Tomahawk set of chips. As a general refresher, the Tomahawk chip series is the small buffer, moderate forwarding table size hardware network switching platform on which a wide array of 1RU (and some chassis) routers (often called switches, but this is just a bad habit of the networking world) used in large scale data centers. In fact, I cannot think of a single large scale data center operating today that does not somehow involve some version of the Tomahawk chip set.
What does this all mean? While I will probably end up running a number of posts on SDKLT over time, I want to start with just some general observations about the meaning of this move on the part of Broadcom for the overall network engineering world.
This is a strong validation of a bifurcation in the market between disaggregation and hyperconvergence in the networking world. Back when the CCDE was designed and developed, there was a strong sense among the folks working on the certification that design and operations were splitting. This trend is still ongoing, probably ultimately resulting Continue reading
YouTube developed Vitess because it needed to scale massive amounts of traffic.
The semiconductor firm says this is its “best and final” offer.
Kurt Marko does a great job of explaining Intent Based Networking as an overall trend. I broadly agree with this perspective. Intent based networks are the new hotness among those needing a response to network complexity. We provide the 101 along with a reality check on what is available today. Intent-based networking portends the future […]
Verizon boards the ONAP train; Huawei has yet another U.S. setback; and AWS and Salesforce want to say goodbye to Oracle.
It will not happen for a long time, if ever, but we surely do wish that Amazon Web Services, the public cloud division of the online retailing giant, was a separate company. Because if AWS was a separate company, and it was a public company at that, it would have finer grained financial results that might give us some insight into exactly what more than 1 million customers are actually renting on the AWS cloud.

The ONF admits work is still needed before CORD is ready for deployments.
There has been much recent talk about the near future of code writing itself with the help of trained neural networks but outside of some limited use cases, that reality is still quite some time away—at least for ordinary development efforts.
Although auto-code generation is not a new concept, it has been getting fresh attention due to better capabilities and ease of use in neural network frameworks. But just as in other areas where AI is touted as being the near-term automation savior, the hype does not match the technological complexity need to make it reality. Well, at least not …
