Understand Rip Routing Timers All in One Shot!
This post is part of a series of posts about dynamic routing protocols and especially RIP. We’ll try to get a deep understanding of its operation and function as an introductory to dynamic routing logic in general. You’ll see that what we think easy may hide an incrementing complexity… A little introduction Before we start...
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...
How Is It Nat-Friendly Your Transit Network?
In this post, we’ll review the general idea behind NAT operation and how it could affect positively (friendly) or negatively (unfriendly) the performance of our network services on the cloud. Introduction Networks (and applications) are getting more and more global and the usage of NAT is inevitable. To run application efficiently such global networks (that...
How to SSL VPN to my Home Network
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...
Multicast Routing: A Step By Step… Part 1/6
In this post we review a basic multicast routing operation, step by step using output from routers console and traffic packet capture (using wireshark). Introduction This blog is a part of a serie of blogs about multicast routing: How does multicast work In IPv4, multicasting servers use class D range of addresses: 224.0.0.0-239.255.255.255. Some addresses...

BGP Session Keepalive And Hold Times

dexterd8 months ago3 months ago05 mins

In this post we’ll deep into the operation of BGP that is a Border Gateway protocol aimed at connecting (routing information exchange) autonomous system in contrast with IGP (Interior Gateway Protocols) that run into each autonomous system. Thus, we do not need to have detailed information about IGPs to exchange routing information… before this routing…...

Multicast Routing: PIM dense… Part 2/6

dexterd7 months ago3 months ago05 mins

In this blog let’s study PIM dense multicast routing. Introduction This post is a part of a serie of posts that introduce the operation of multicast routing: We explore in this post, the operation of PIM multicast routing protocol in the by default operation mode PIM Dense mode. The idea is very simple: flood the…...

Is It Sufficient RIP Split-Horizon Rule To Prevent Routing Loops?

dexterd7 months ago3 months ago05 mins

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…

Multicast Routing: Rather Than Dense, Sparse It And Let’s Meet At Rendez-Vous Point… Part 5/6

dexterd8 months ago3 months ago05 mins

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…...

Introduction to Starlink Networking

dexterd1 month ago2 months ago03 mins

Let’s explore in this article the general operation of Starlink and how it can benefit. Introduction Undoubtedly Starlink helps resolve many connectivity issues and at least starting to offer a cost effective alternative to traditional costly satellite solution with regards to the same use cases. But it is not limited to. Let’s explore in this…...
