In this post, we present the work fully available at this link: A NURBS-optimized dRRM solution in a mono-channel condition for IEEE 802.11 entreprise Wlan networks, about dynamic RRM (Radio Resource Management) and especially on a NURBS optimized solution of RRM. NURBS relates to Non-Uniformal Rational B-Splines surfaces concepts usually known in CAGD (Conception Aided…
In this post, let’s recall what is subnetting for routing and switching purposes and how it is done. Motivation Network subnetting is very important subject that maybe referred to as VLSM for variable length subnetting. The basic idea is about managing a space of IP addresses (IPv4). Historically, a network length or space was fixed…...

Introduction Dynamic routing protocols exchange routing information before populating routing tables and forwarding packets. For this task, RIP (routing information protocol) put into play many machanisms and rules to guarantee that this routing information exchange is consistent: not contradictory among routers. An example of such inconsistency is to receive the same routing information on two…
In this blog, we will setup a Checkpoint lab using virtualbox and gns3 on windows. Introduction In this lab we implement a basic security architecture to demonstrate the operation of a firewall cluster to protect our network. Our “security domain” is segmented into four zones: Security topology Our security topology is compound by two security…...

In this blog let’s try to connect to a home network from outside (internet) in a secure manner using SSL. NAT and PAT NAT and PAT is what allowed local IP addresses translation or mapping to some routable public IP address (over the internet). This mapping can be one to one (NAT) or many to…
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…...
