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...
Static Routing… Metric?!
In this post we explore the operation of static routing, epecially the use of the metric feature, in a network that already runs an IGP (RIP routing protocol). Network setup In our 3 routers RIP network, both R1 and R3 advertise 13.13.13.13/32 network into RIP domain R3 is configured to offset (to add) all network...

A Nurbs Based Technique for an Optimized Transmit Opportunity Map Processing in Wlan Networks
Dynamic Radio Resource Management helps overcome interferences in dense WLAN deployments. By processing data from upper-layers services, it could optimize and enrich end-to-end wireless client experience. This experience may be tight (related) to a transmit opportunity function that hints on the radio interface condition, and effectiveness of the transmission itself from different points of view:...
Static Routing with Intermediate Address in Checkpoint Firewall
In this blog, let’s study static routing with an intermediate address to resolve in a Checkpoint firewall. Introduction Static routing is supported by CKP (Checkpoint firewalls or gateways). Let’s recall that a static route defines a destination subnet or network and the way to reach it: the outgoing interface on the gateway, a connected nexthop...

10 Security Measures Against 10 Attacks In A LAN Network

luffyd8 months ago3 months ago05 mins

In this blog, we discuss 10 security measures or controls that a LAN should have enabled. Introduction Before we present the 10 security measures to enable, let’s introduce the operation of a switch in a LAN network. Switches An Ethernet switch is the central element of a LAN network and operates at data link OSI…

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

dexterd8 months ago3 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 Nurbs-Optimized dRRM Solution in a Mono-Channel Condition for IEEE 802.11 Enterprise Wlan Networks

einsteind1 year ago3 months ago02 mins

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…
