First, disclaimer: I’m an HPE employee. Hewlett Packard Enterprise is a major contributor to the OpenSwitch project. Just thought you should know in case you think that affects my opinion here.

Got your attention, didn’t I? After the first couple of posts on OpenSwitch and a lot of discussions about this cool new project at some recent events, there was one piece of feedback that came back fairly consistently from the traditional engineers. OpenSwitch is hard to get running because there’s so many new things to learn.
When released in November of last year, the initial demonstration environment was actually pretty simple and streamlined to get up and running, as long as you’re a developer.
The process involved the standard set of dev tools:
For anyone involved in a development environment, these tools are like an old hoody on a cold winter day. Welcome and familiar.
But for the majority of network engineers who are far more comfortable with a console cable and Continue reading
The web is an collaborative ecosystem. Web standards exist to ensure that participants of the network behave in a predictable way. If network participants deviate from the established standards then there can be unintended consequences. This blog post is about one of these unintended consequences.
A group of researchers recently published a paper "Forwarding Loop Attacks in the Content Delivery Networks" describing what can happen when web services interact in a non-compliant way. They describe an attack where a malicious user can force multiple service providers to send each other an unending stream of requests in a loop. This request loop can result in resource exhaustion and denial of service at the service provider. This paper also demonstrated that the attack is practical, and can be performed using a large list of service providers.
CloudFlare's service has been modified to be standards-compliant with respect to HTTP proxying. However, fixing the vulnerability that enables this attack requires all proxy services to conform to the same standards. If even one service provider is non-compliant, the attack can still be carried out against compliant services. In this post, we will describe the attack and explain how a proxy services can go from being Continue reading
Today, Unikernel Systems announced that it is joining Docker. Please read the main notice posted at unikernel.com and the Docker blog post at http://blog.docker.com/2016/01/unikernel/.
An important part of the work of Unikernel Systems is to support the growing unikernel movement, which includes contributing to a number of open source projects as well as supporting this community website, unikernel.org. The Unikernel Systems team will continue this work.
Through further interaction with the Docker project and community, the open source unikernel community will receive increased visibility and contributions which will accelerate the adoption of unikernels.

The breadth of address allocation options available in IPv6 world confuses many engineers thoroughly fluent in IPv4, but it also gives operating system developers way too many options… and it turns out that different operating systems behave way differently when faced with the same environment.
