- sFlow agent now reports tunnel and MPLS structures.The sFlow Tunnel Structures specification enhances visibility into network virtualization by capturing encapsulation / decapsulation actions performed by tunnel end points. In many network virtualization implementations VXLAN, GRE, Geneve tunnels are terminate in Open vSwitch and so the new feature has broad application.
...
- Add experimental version of OVN. OVN, the Open Virtual Network, is a
system to support virtual network abstraction. OVN complements the
existing capabilities of OVS to add native support for virtual network
abstractions, such as virtual L2 and L3 overlays and security groups.

For best article visual quality, open Checkpoint Firewall CLI tool “dbedit” and quick lab examples directly at NetworkGeekStuff.
In this article, I am going to give you a quick guide how to run a single checkpoint FW as virtual machine quickly on your notebook and then super-quick introduction to configuring such checkpoint firewall via CLI instead of the much more typical SmartDashboard. This articles is very focused on what I personally needed to do lab for in work and is in no way a comprehensive guide to the “dbedit” tool from Checkpoint or any firewall automation.
We are using Checkpoint firewalls in our customer networks at work and are heavily using SmartDashboard and other GUI based tools to manage these firewalls in a large datacenter environments (rulebase of 10k+ firewall rules!) because that is simply our internal standard. However recently there came a push to try to automate a certain aspects of configuring these firewalls because several customer wanted to achieve shorter lead-times at least on few aspects of firewall configurations.
And since Checkpoint FWs do not support any real API for managing policies with it, it came down to CLI tools like dbedit, which we will explore Continue reading

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
More than a third of businesses in the United States currently use the cloud, but by 2020 that number is expected to more than double to a whopping 80%. But even though the cloud is secure, it doesn’t guarantee immunity from data breaches. Now that the cloud is rapidly becoming a mainstream part of IT, businesses must think more critically about how to bolster their security beyond cloud providers’ default security infrastructure—which often proves to be inadequate for the changing face of business.
