ARP- Address resolution protocol, as name suggests it used to resolve IP address to MAC-address used by data link protocol. As network engineer , its default that you should be aware of ARP , there is no excuse for not knowing ARP . This post is specific to those readers who want detailed analysis ,how ARP […]
Forward Networks uses SNMP, screen scraping, and math to model your production network in detail. Then, you can search, verify, and predict using the model.
Previous post in this series – There and Back Again – A Journey Into Network Automation Part 1 – ZTPS In Part 1 I talked about how having an SDN Overlay meant my network configurations were more uniform and consistent. This meant deploying the Arista ZTP Server made sense in automating initial deployment and scale out. […]
BigSecure Architecture combines SDN with commodity switching & x86 service nodes to build a dynamic tool chain for traffic inspection & attack mitigation.
After watching the 2016 AWS Reinvent keynote James Hamilton, I came away with the impression that there is elements that relate to Enterprise IT. So extracted the networking section and recorded some commentary and reactions that I had in a video format. Here is my first attempt at doing some video. I would be interested […]

Please read There and Back Again – A Journey Into Network Automation – Introduction for the context of this post. Deploying an SDN solution, in this case Nuage VSP, has a very definite impact on the physical network. It provides an opportunity to simplify. Nuage VSP, like most ‘commercial’ SDN solutions, provides an Overlay network, […]
I’ve been in networking for 25 years, but up until two years ago I’d had no cause to develop coding skills, nor even any Linux skills, beyond the most rudimentary. This always bothered me a bit, and was starting to bother me more and more. That’s because I realized a fundamental shift in how we were […]
Redundancy is must for ISP in Core and also its equally important for Enterprise to have network up always thus resulting in zero business impact due to network outage. There are different scenarios of failover mechanism depending upon the requirement. First of its kind is Dual POP Dual last mile Dual CE (DPDLDC). It provides […]
Recently I saw the question posed at Network Field Day about why LTE providers can deliver bandwidth to millions of users and “it just works” while delivering bandwidth on the enterprise LAN is still problematic. It’s a great question and one that is not asked often enough when comparing the way ISPs build networks to […]
In continuation of Part1, Part 2 of useful show commands will be focusing little bit more related to troubleshooting tools available in JUNOS local on the router. In any case, do not forget to use “set cli timestamp” to correlate the data and related events. If you would like to find out the configuration knob […]
