vPC Versus VSS Technology
Dans ce blog, nous discutons vPV et VSS. Introduction Si l’objectif “historique” est le même : s’affranchir de la limitation de STP (blocage de ports pour prévenir les boucles), de l’usage des FHRP (HSRP, VRRP) pour équilibrer les liens, d’augmenter les performances en débit et capacité de calcul, d’éliminer les SPOF liés à l’utilisation d’un...
Windows : Drive Healing From Scratch
In this post, let’s understand hard drive operation and try to find a methodology (procedure) to troubleshoot it (and heal it if needed). Lab setup Let’s describe in detail our “simple” setup. for the purpose of our test we mount this setup: PC + USB to SATA adapter + Seagate 1T HDD. The most basic...
ML-Optimized Beam-Based Radio Coverage Processing in IEEE 802.11 Wlan Networks
In this post, we present the work fully available under this link: ML-Optimized Beam-based Radio Coverage Processing in IEEE 802.11 WLAN Networks, about radio coverage processing in wlan and its optimization using machine learning (ML). Why dynamic RRM is important Dynamic Radio Resource Management (RRM) is a major building block of Wireless LAN Controllers (WLC)...
Bézier Curves-Based Novel Out-Of-Path Beamforming Calibration Technique in IEEE 802.11 Wlan Networks
This post is descriptive of our work on RRM or radio resource management in WLAN (Wireless LAN) and especially on the operation of beamforming, available here : Bézier Curves-Based Novel Out-of-Path Beamforming Calibration Technique in IEEE 802.11 WLAN Networks First of all what is beamforming Beamforming is a major building block of Radio Resource Management...
Build a Mining Strategy From Scratch
In this blog’s, let’s discuss a “winning” strategy to start mining. Introduction First of all by definition mining is the technique by which you help build the blockchain. let’s imagine that the blockchain in this scheme is like a “big” distributed computer made of all miners computers. the central intelligence of this computer allows the...

Multicast Routing: Hold ASM For A Moment, Let’s Do SSM!… Part 4/6

dexterd6 months ago1 month ago06 mins

In this blog, we introduce SSM way of multicasting. Introduction and definitions This post is a part of a serie of post about Multicast operation from the most basic setup to a much complicated one (scenario that include more routing and receiving options, etc.). We will explore the operation of SSM (Source Specific Multicast) in…...

My First Scapied IPV6 Packet

mehdi6 months ago1 month ago017 mins

In this blog, let’s build our first IPv6 packet. Introduction The idea of this lab is to craft an IPv6 packet from scratch using Python and Scapy library. The IDE I use is JetBrains PyCharm Community Edition 2018.3.1 x64 which is available for free at : https://www.jetbrains.com/pycharm/download/download-thanks.html?platform=windows&code=PCC The IDE The IDE interface looks like in…

DUAL Route FSM Processing Of EIGRP Queries

dexterd6 months ago1 month ago13 mins

In this blog, we study how DUAL route FSM Processes EIGRP Queries. Introduction Let’s recall that EIGRP is one of the so called IGP routing protocols. IGP stands for interior routing protocols as opposed to EGP or exterior routing protocols. In addition EIGRP is a hybrid as it borrows some similarities to distance-vector and link-state…...

Vlan Propagation And Cisco FabricPath

dexterd6 months ago1 month ago06 mins

In this post, we explore the operation of Cisco FabricPath (FP) and more specifically Vlan information propagation in this fabric in comparison with other platforms: Catalyst for example from the same vendor. Introduction The case is to learn how the switches that are part of the LAN network learn about and support Vlan operation: is…...
