LinkMeUp. Edition of 11. Cisco TAC, CEF, FIB

the First year of life podcast, we finish on a very positive note — we had a guest Dmitry Jdima and engineer for Cisco TAC — Anatoly Tsyganenko.

Everything you wanted to know about the work centre technical support in Cisco process cases, and by what means of analysis have engineers in the first part of the podcast.
Next will be a qualitative story about the mechanisms of the Proccess Switching, Fast Switching and Cisco Express Forwarding. We will dive into the RIB, the FIB, the realization of all this in hardware, look at how the packet is processed on a linear, processing fees and factories switching.
Pretty hardcore and turned on the duration and depth.

Why I left Google Zurich

They recruit the best engineers pay them large enough (even for Switzerland) salary and create an amazing environment for work, free food, massage at the office, the phantasmagoric recreation area , childrens slide down directly into the dining room, etc. This is very cool, like to write journalists, but it doesn't matter. Well, how many times will you walk down the hall on the hill and is it important? Free food has led to the fact that the majority of Googlers fat pounds five after a job, thus denying yourself the pleasure to go to lunch every day in a new restaurant.

New web-interface for statistics and listen to the calls for IP PBX Asterisk

Изображение
the Idea of writing web-interface for statistics and listen to the calls for IP PBX Asterisk is not left me for several years now. The solutions found in Internet, are not satisfied on certain criteria — somewhere lacked functionality, some of them are not pleasing to the eye. And so, armed with technology stack and riding warhorse provided by ServerClub I went. The result of my journey has become a new interface , with charts, graphs and the ability to download and listen to the calls. I will not further bore you with words, here are a couple of screenshots: And under the cut are waiting for you a video guide on the interface, necessary settings and detailed description of the available functionality. the Interface. That post didn't look like a bed sheet from the screenshots, I made a little slideshow where you can see the interface. Description. The already existing plans. Currently implemented the following functionality: Incoming calls:
