Setup A Checkpoint Lab Using VirtualBox And GNS3 On Windows
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...

Cognitive Directional Cost-Based Transmit Power Control in Ieee 802.11 Wlan
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:...
Bézier Curves Based Novel Calibration Technique of Beamformers in Ieee 802.11 Wlan Networks
In this post, we present the work entirely accessible at link: Bézier Curves Based Novel Calibration Technique of Beamformers in IEEE 802.11 WLAN Networks, about a new way of doing beamforming in the wlan unified (WLC-based) network. Let’s recall that beamforming is the mean by which an access point (AP) concentrate the electromagnetic energy toward...
Let’s Find Out About (Static) MPLS… From The Start!
In this post, we’ll discuss the motivation and a basic operation of an MPLS network. In the first part, we’ll introduce this protocol and our setup (using GNS3) that put it into play. We’ll try next, to explore the functionnality of this protocol using a very simple and basic example using both Cisco and HPE...

When A Gateway Says: “Not A Good Gateway… Set Redirection!”

dexterd11 months ago6 months ago19 mins

In this blog, we discuss when a gateway decides that it’s not a good gateway any more and proposes a new gateway to the host by setting redirection. Introduction We explore how a gateway (a router) present in a LAN handles routing to the outside of this network and uses redirection to enhance this operation….

A Novel Beamforming Based Model of Coverage and Transmission Costing in Ieee 802.11 Wlan Networks

einsteind6 months ago6 months ago03 mins

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…...

Transmit Power Control In IEEE 802.11 Cisco WLAN Networks

dexterd11 months ago6 months ago07 mins

TPC stands for Transmit Power Control. It’s a one of Cisco RRM, Radio Resources Management, techniques that are aimed at tackling interference, cross and co-channel, in Wlan networks. RRM: TPC, CHD and DCA It works tightly with CHD, Covergate Hole Detection, to optimize transmit power. TPC tends to minimize the transmit power and CHD to eliminate…...

TACACS+ for you Network

luffyd4 months ago5 months ago03 mins

You have deployed your network which means installed, interconnected, configured and run your network devices. The connectivity between your users and servers is up and running. That a great news! but you’re worried about who may access locally or remotely to your network devices and eventually, change their configuration and operation… To secure this access…...
