FTC Worries that Broadcom’s Purchase of Brocade Creates a Fibre Channel Switch Monopoly
The FTC doesn’t want the deal to quash competition with Cisco.
Multi-Stage Builds
This is part of a series of articles describing how the AtSea Shop application was built using enterprise development tools and Docker. In the previous post, I introduced the AtSea application and how I developed a REST application with the Eclipse IDE and Docker. Multi-stage builds, a Docker feature introduced in Docker 17.06 CE, let you orchestrate a complex build in a single Dockerfile. Before multi-stage build, Docker users would use a script to compile the applications on the host machine, then use Dockerfiles to build the images. The AtSea application is the perfect use case for a multi-stage build because:
- it uses node.js to compile the ReactJs app into storefront
- it uses Spring Boot and Maven to make a standalone jar file
- it is deployed to a standalone JDK container
- the storefront is then included in the jar
Let’s look at the Dockerfile.
The react-app is an extension of create-react-app. From within the react-app directory we run AtSea’s frontend in local development mode.
The first stage of the build uses a Node base image to create a production-ready frontend build directory consisting of static javascript and css files. A Docker best practice is named stages, e.g. “FROM Continue reading

Submarine Cable Basics
Submarine Cable is probably the most important topic for the International traffic. More than 99% of the International traffic , including data, voice and video is carried over Submarine Cables. But still submarine cables is not very well known topic among the network engineers, especially if you are not working in the Service Provider, […]

What is NASA Doing with Big Data? Check this Out
Within the time you read the above sentence, NASA could have collected 1.73 gigabytes of data from around 100 missions which are active currently. NASA doesn’t stop doing this and the rate of collection is growing in an exponential manner. So, managing this kind of data is an uphill task for them. But the data which NASA collects is highly precious and its significance is immense in NASA’s science and research. NASA is trying extremely hard to make this data as approachable and accessible as possible for their daily tasks, various predictions in the universe, and for the human well-being through its innovations and creativity.
In version 2.0 of their “Open Government Plan” in the year 2012, NASA discussed, but did not go deeply into the work they have been doing regarding “Big Data” and they believed that they have much more to explore in this field.
We all know what big data is and what its uses are. So, I don’t think there is any need to mention what really big data is and let’s move on with other topic.

BGP FlowSpec on white box switch
Unfortunately, FlowSpec is currently only available on high end routing devices and so experimenting with the technology is expensive. Looking for an alternative, Cumulus Linux is an open Linux platform that allows users to install Linux packages and develop their own software.
This article describes a proof of concept implementation of basic FlowSpec functionality using ExaBGP installed on a free Cumulus VX virtual machine. The same solution can be run on inexpensive commodity white box hardware to deliver terabit traffic filtering in a production network.
First, install latest version of ExaBGP on the Cumulus Linux switch:
curl -L https://github.com/Exa-Networks/exabgp/archive/4.0.0.tar.gz | tar zxNow define the handler, acl.py, that will convert BGP FlowSpec updates into standard Linux netfilter/iptables entries used by Cumulus Linux to specify hardware ACLs (see Netfilter - ACLs):
#!/usr/bin/python
import json
import re
from os import listdir,remove
from os.path import isfile
