VMware’s Gabriele Di Piazza Discusses Virtualization, IoT and 5G at MWC
Gabriele Di Piazza, VP of solutions, Telco NFV Group at VMware, shares his predictions for what will be generating the most buzz at MWC.
Cloud-Managed Data Centers: Pros and Cons
The idea of using cloud brains to simplify on-premises management holds a lot of promise for the future.
5G Trials, IoT Demos Will Dominate at 2017 Mobile World Congress
More than 101,000 attendees from 160 countries are expected at the conference.
NFV and MEC Raise Their Lovely Heads at Mobile World Congress
The show is hosting three panels on these topics.
Telco Data Centers Get a New Look at MWC
Ericsson probably won't be the only vendor to show off data center gear at MWC.
HPE & Intel – On the Forefront of 5G
Learn how HPE and Intel are collaborating to make edge computing a reality, maximizing service agility in 5G networks so that they will be able to support requirements we haven’t even thought about yet.
QUIC
An easy way to see if you have any QUIC traffic on your network is to use the standard sFlow instrumentation built into network switches. Configure the switches to send sFlow telemetry to an sFlow collector for visibility into network traffic.
For example, use Docker to run the sFlow-RT active-flows application to analyze the sFlow data stream:
docker run -p 6343:6343/udp -p 8008:8008 -d sflow/top-flowsAccess the web interface at http://localhost:8008/ and enter the following Flow Specification to monitor QUICK flows:
dns:ipsource,dns:ipdestination,quicpackettypeNote: Real-time domain name lookups describes how sFlow-RT incorporates DNS (Domain Name Service) requests in its real-time analytics pipeline so that traffic flows can be identified by domain name.
Python – Kirk Byers Course Week 4 Part 2
This post will describe the exercises and solutions for week two of Kirk Byers Python for Network Engineers.
Our next task is to parse data from show version from a device.
II. Parse the below 'show version' data and obtain the following items (vendor, model, os_version, uptime, and serial_number). Try to make your string parsing generic i.e. it would work for other Cisco IOS devices. The following are reasonable strings to look for: 'Cisco IOS Software' for vendor and os_version 'bytes of memory' for model 'Processor board ID' for serial_number ' uptime is ' for uptime Store these variables (vendor, model, os_version, uptime, and serial_number) in a dictionary. Print the dictionary to standard output when done. Note, "Cisco IOS Software...Version 15.0(1)M4...(fc1)" is one line. >>>>> show version data <<<<< Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.0(1)M4, RELEASE SOFTWARE (fc1) Technical Support: Copyright (c) 1986-2010 by Cisco Systems, Inc.

Hard Reality: No Enterprise Data Center Solution is an Island
A vendor’s SDN solution ecosystem strategy and partnerships can make the difference between long term SDN success, including lifecycle ROI protection, and failure.
Networking Grows To Invisibility
Networking is done. The way you have done things before is finished. The writing has been on the wall for quite a while now. But it’s going to be a good thing.
The Old Standard
Networking purchase models look much different today than they have in the past. Enterprises no long buy a switch or a router. Instead, they buy solution packages. The minimum purchase unit is a networking pod or rack. Perhaps your proof-of-concept minimum is a leaf-spine of no less than 3 switches. Firewalls are purchased in pairs. Nowhere in networking is something simple any longer.
With the advent of software, even the deployment of these devices is different. Automation and orchestration systems provide provisioning as the devices are brought online. Network Monitoring Systems ensure the devices are operating correctly via API call instead of relying on SNMP. Analytics and telemetry systems can pull statistics on the fly and create datasets that give you insight into all manner of network traffic. The intelligence built into the platform supporting the hardware is more apparent than ever before.
Networking is no longer about fast connectivity speed. Instead, networking is about stability. Providing a transport network that stays healthy instead of Continue reading
Redistribute Static on Juniper & Cisco
How Does Internet Work - We know what is networking
In case you wondered how to redistribute static routes into dynamic routing protocol you are at the right place. This is normally a basic thing to do, but I will let you know how to do it in different ways on different vendor devices so it might be interesting. We will go through few examples of normal static to OSPF redistribution and then see how it can be partially done with only part of static routes using route filters. I’ll do it on Cisco and Juniper devices so we can see what’s the difference. Cisco In Cisco CLI, redistribute static
