Teridion, our sponsor for todays show, is changing the basic idea of how to select best paths across the Internet and deliver content quickly through its global network of virtual cloud routers. The post Show 307: Teridion s New Take On SaaS Performance & Quality Of Experience (Sponsored) appeared first on Packet Pushers.
In the previous part 1, we have installed basic HPE DCN system on a group of ESXi hosts. But we didn’t actually done anything inside it, so lets fix this by creating a first “HelloWorld” customer that we will call “NetworkGeekStuff” and deploy some virtual machines to this virtual network. In this part we are going to fix that and we will create a very basic virtual customer, a username/password for that customers administrator and create a small 3 tier ( database / internal / dmz) network using HPE DCN’s overlay virtual network. And at the very end, we are going to connect to this network a few virtual machines.

We will start exactly where we ended on previous part 1, but to double-check, I am going to show the main views of my vCenter and VSD environment to show how “empty” it is after a pure install that we did so far. So starting with this, below is my view on vCenter boxes, with Continue reading
The CloudFlare London office hosts weekly internal Tech Talks (with free lunch picked by the speaker). My recent one was an explanation of the latest version of TLS, 1.3, how it works and why it's faster and safer.
You can watch the complete talk below or just read my summarized transcript.
The Q&A session is open! Send us your questions about TLS 1.3 at [email protected] or leave them in the Disqus comments below and I'll answer them in an upcoming blog post.
To understand why TLS 1.3 is awesome, we need to take a step back and look at how TLS 1.2 works. In particular we will look at modern TLS 1.2, the kind that a recent browser would use when connecting to the CloudFlare edge.
The client starts by sending a message called the ClientHello that essentially says "hey, I want to speak TLS 1.2, with one of these cipher suites".
The server receives that and answers with a ServerHello that says "sure, let's speak TLS 1.2, and I pick this cipher suite".
Along with that the server sends its key share. The Continue reading

CT ensures that a new feature is tested at every stage from planning to design.
MTU is most important aspect for proper functionality of any application. In this blog post I will highlight MTU handling by Junos based devices for (802.3 un-tag and 802.1Q tag packets) .
Simple 802.3 packet header is shown above total packet size is 1514 bytes (14 bytes header + 1500 bytes max payload). Now we will see how Junos based devices handle MTU on access ports.
Link-level type: Ethernet, MTU: 1514, MRU: 0, Link-mode: Auto, Speed: Auto, BPDU Error: None, MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow control: Disabled, Auto-negotiation: Disabled,

Protocol eth-switch, MTU: 1514
Hi folks, I recently posted an article on one of the official Red Hat blogs about the new Neutron integration between RHV and RHOSP. I have to say it’s very cool and might change the way you look at networking capabilities in RHV, at least if you’re also using RHOSP in the same data center.
As a side note, I’ve mentioned my friend and colleague, Tony James in recent posts and he makes another appearance this week. He helped pull together the configuration steps as well as the demo that we recorded. Big kudos to to “Big T”.
Back to the actual integration. If you don’t want to look at the other article, the condensed version of “why should you might care” is as follows:
Those are the 3 big use cases, in a nutshell. If Continue reading
