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 accessible via this link: dRRMize your WIFI… and get your head out of the box!, about radio resources management in a WLAN enterprise network. RRM or Radio Resource Management being fundamental to the operation any unified wireless network and a master piece of any WLC (the Wlan controller)….
Dans ce blog, nous discuterons du SD-WAN pour essayer de comprendre son enjeu et avantage pour l’entreprise. Nous commençons par explorer l’offre du marché, définir la technologie et son principe de base, du besoin de son usage et scénarios, avant de discuter de son architecture, implémentation et troubleshooting de son opération. Marché (offres du) Incontestablement…
In this post we present the work available at this link: Cognitive directional cost-based transmit power control in IEEE 802.11 WLAN, about the how to model the radio coverage area in enterprise Wlans. IEEE 802.11 Wlan networks are challenging IEEE 802.11 Wlan networks are constantly challenged for maximum overall service performance and new mobility applications:…
In this blog, we study RPF operation. Introduction This blog is a part of a serie of blogs about multicast routing: Test network In our test network RPF in action At R2 A “show ip interface brief” shows Digging into the interface tunnel0 details The tunnel was created by PIM process to join the RP…...

In this post let’s detail the operation of PIM (Protocol Independent Multicast) in sparse mode. Previous posts tackled the operation of PIM dense mode. Let’s recall that PIM is the multicast routing protocol that allows PIM routers exchange information needed distribute multicast traffic to receivers. Introduction This blog is a part of a serie of…...
