Introduction Dans cet article nous discutons de la fonction de base d’un WAF ou pare-feu d’applications web. Comme son nom l’indique il s’agit de sécuriser l’application, plus précisemment l’accès à cette application, et ne se préoccupe pas nécessairement d’autres aspects sécuritaires : réseau, d’autres applicatifs (niveau 7 OSI) ou de transport (niveau 4 et 5…
In this blog let’s study from the source multicast routing Introduction This blog is a part of a serie of articles about multicast routing: Previously, we’ve introduced multicast routing and PIM protocol operation in dense mode. In this blog, we’ll check the operation PIM multicast routing protocol from the source perspective. The lab setup The…...

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…
In this post, we present the work on radio coverage in Wlans, accessible at this address: A novel beamforming based model of coverage and transmission costing in IEEE 802.11 WLAN networks, about how to modalized the radio area coverage to enhance costing of the transmission opportunity in such networks. What this work is about The…...

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…
Wireless technology is everywhere, overwhelming, in the heart of every IT architecture, and this is for many reasons: increase of user mobility, ease of network operation, scalability in deployment, enabling of localisation services, user and equipment presence detection, etc. A littre introduction It is a fact that the technology supports a wide range of applications…
