On today's sponsored Heavy Networking, VIAVI Solutions joins the Packet Pushers to discuss the intersection of network performance management (NPM) and security. We discuss how network and security teams can leverage VIAVI's packet capture capabilities, how it enriches flow records with additional data to provide valuable context, and how the concept of end user experience informs VIAVI's approach to NPM.
The post Heavy Networking 434: Solving Network Performance And Security Problems With VIAVI Solutions (Sponsored) appeared first on Packet Pushers.

In my last post – we took a look at how we could leverage etcd from Python. In this post, I want to propose a use for leveraging etcd as a sort of message bus for ExaBGP. We saw some pretty compelling features with etcd that I think can work nicely in our ExaBGP model. So without further blabbering – let’s start coding.
Note: I assume you have a local instance of etcd installed and it is currently empty. If it’s not empty – you’ll want to clear it all out using a command like this ETCDCTL_API=3 etcdctl del "" --from-key=true
If you recall – in our last post on ExaBGP we were at a point where the ExaBGP process was using two Python programs we wrote. One for processing received routes (exa_bgp_receive.py
) and one for sending route updates (exa_bgp_send.py
). My goal here it to remove a lot of the logic for static route processing from these two scripts and make them more about route processing. More specifically – I want to turn the two Python scripts that ExaBGP is running on our behalf into simple programs that read/write to to/from etcd. Once we Continue reading
Wherever you look you find three kinds of people: those that build tools they need, those that find the tools they need, and those that yammer about the lack of tools without ever doing anything to solve the problem.
Daniel Teycheney is clearly in the first category. When faced with “collect some data and create a simple report” hands-on assignment during the Building Network Automation Solutions course he started creating a toolbox of playbooks that can be used in initial network auditing. I’m positive you’ll find tons of useful tidbits in his code ;)

As going through learning some basic programming, I encountered Decorators. I should be very honest if any of you are trying to figure out or learn what decorators in python do from my blog post you are dangerously in trouble.
So what this post about if not learning, well its mostly on what the functionality is so that you can learn the concept from better programming resources.
Let’s examine the below code
The output will be something like below
What’s in this code:
The first thing you have to realize is that some representation with ‘@’ symbol. If you have noticed get_reinfo and get_modelinfo functions, they have one thing in common which is to connect to the device and get output before they parse the required fields, that what a Decorator is helping us to do here, we extend that wrapping functionality around new functions without having to write everything or globalize everything.
At least that is what I understood. So, next time when you are writing some code try to think if you can incorporate decorators into them.

With last’s week landmark release of NSX-T 2.4, and the RSA conference in full swing, this is the perfect time to talk about to some of the new security functionality we are introducing in NSX-T 2.4.
If you prefer seeing NSX-T in action, you can watch this demo which covers Layer 7 application identity, FQDN Filtering and Ientity Firewall. Or if you are around at RSAC in San Francisco this week, swing by the VMware booth.
Micro-segmentation has been one of the key reasons why our customers deploy NSX. With Micro-segmentation, NSX enables organizations to implement a zero-trust network security model in their on-premise datacenter as well as in the cloud and beyond. A key component making Micro-segmentation possible is the Distributed Firewall, which is deployed at the logical port of every workload allowing the most granular level of enforcement, regardless of the form factor of that workload – Virtual Machine – Container – Bare Metal Server or where that workload resides – On Premise – AWS -Azure – VMC.
NSX-T 2.4 provides significant new security features and functionality such as Context-aware Micro-segmentation, Network (and Security) Intrastructure as Code, E-W Service Insertion and Guest Continue reading

With this post we illustrate the potential applications of Cloudflare Workers in relation to search engine optimization, which is more commonly referred to as ‘SEO’ using our research and testing over the past year making Sloth.
This post is aimed at readers who are both proficient in writing performant JavaScript, as well as complete newcomers, and less technical stakeholders, who haven’t really written many lines of code before.
Working with various clients and projects over the years we’ve continuously encountered the same problems and obstacles in getting their websites to a point of “technical SEO excellence”. A lot of these problems come from platform restriction at an enterprise level, legacy tech stacks, incorrect builds, and years of patching together various services and infrastructures.
