Tour De NS2: Queuing Models and Simulations

Hi guys,

Today we are going to discuss about a new topics : "Queuing Models in NS2". I hope you all know about different queuing models and i am least interested on discussing about that. We are going straight to our main topic.

Why Queuing Models and Simulations??

Simulations are normally used in the analysis part of queuing models
Queuing Model is nothing but a simple representation of a network flow with traffic.
Queuing models provide the analyst with a powerful tool for designing and evaluating the performance of queuing systems.
Normally it measures; Utilization of Server, Length of Waiting Bucket and Delay Duration.
In simple systems, We can calculate it mathematically but in the case of large and complex networks, we need simulation.

Elements In a Queuing System

Customer : It is nothing but anything which requires services from server.
Server : Refers to any resource which provides service to customer.
Calling Population : A group of customer. It may be finite or infinite.

Link State Routing Protocol

Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta...

Matter: A next generation home standard

The smart home is evolving. To date, if you've wanted to get into developing a smart home, you've had to deal with the multitude of smart home ecosystems, and making sure that each device you buy is compatible. That, however, may soon change — thanks to new smart home standard called Matter. Matter isn't available just yet, but when it is finally released, it could completely change how you buy smart home products, for the better. All of the best smart home devices could soon support the standard, helping them all work together nicely, and ensuring that no matter what products you buy, you'll be able to use them. Matter is basically the name of a new smart home connectivity standard . But this standard is a little unlike others. That's because of the fact that it's being developed by the Connectivity Standards Alliance, which counts hundreds of companies as members. That includes the likes of Google, Alexa, and Apple. So, whether you prefer to use Google Assista...

New interactive stickers for Stories

Instagram has introduced several new features to Stories, offering interactive ways to share music, photos, and videos. One of the most interesting additions is a feature called Reveal , which blurs the content of a story post and requires viewers to DM the person who shared it in order to see it. Instagram's head, Adam Mosseri, has emphasized the importance of direct messages on the platform, with stories and DMs driving most of Instagram's growth. Requiring a DM to view content represents the next step in boosting engagement, and creators are likely to use it as a tactic to increase their stories' engagement. Another new feature, Frames, adds a Polaroid overlay to images that initially appear gray. Users can shake their phone to reveal the photo, resembling the process many people associate with Polaroid pictures, despite the fact that shaking Polaroids is not recommended by the company during development. Instagram has also introduced a music-based template feature calle...
