Controlling Broadcasts and Multicasts
Controlling Broadcasts and Multicasts Introduction The first step in controlling broadcast and multicast traffic is to identify which devices are involved in a broadcast or multicast storm. The following protocols can send broadcast or multicast packets: Address Resolution Protocol (ARP) Open Shortest Path First (OSPF) IP Routing Information Protocol Version 1 (RIP1) Service Advertising Protocol […]
Data Transmission – Broadcast
Data Transmission – Broadcast Introduction The term “Broadcast” is used very frequently in the networking world . You will see it in most networking books and articles, or see it happening on your hub/switch when all the LED’s start flashing at the same time ! If you have been into networking for a while you […]
Multicast IP List
Multicast IP List Introduction This page contains all the Multicast IP Addresses and shows what protocol they are mapped to. Should you ever use a packet sniffer to try and see what’s on the network and you capture a packet with a destination IP Address of 224.X.X.X, then simply look up this list and you […]
Introduction To Multicast
Introduction To Multicast Introduction To understand what we are going to talk about, you must be familiar with how MAC addresses are structured and how they work. The MAC Addresses page is available to help you learn more about them.. A multicast is similar to a broadcast in the sense that its target is a […]
Unicast
Unicast Introduction Compaired to broadcasts and Multicasts, a Unicast is very simple and one of the most common data transmissions in a network. The Reason for Unicast Well it’s pretty obvious why they came up with Unicasts, imagine trying to send data between 2 computers on a network, using broadcasts ! All you would get […]
Media Access Control – MAC Addresse
Media Access Control – MAC Addresses Introduction Media Access Control (MAC) addresses are talked about in various sections on the site, such as the OSI-Layer 2, Multicast, Broadcast and Unicast. We are going to analyse them in depth here so we can get a firm understanding of them since they are part of the fundamentals […]
Data Transmissions
Introduction To Data Transmission Introduction Routable protocols enable the transmission of data between computers in different segments of a network. However, high volumes of certain kinds of network traffic can affect network efficiency because they slow down transmission speed. The amount of network traffic generated varies with the 3 types of data transmissions: Broadcast Multicast […]
Network Topologies
Network Topologies Introduction Network topologies can take a bit of time to understand when you’re all new to this kind of cool stuff, but it’s very important to fully understand them as they are key elements to understanding and troubleshooting networks and will help you decide what actions to take when you’re faced with network […]
Introduction To Networking
Introduction To Networking Introduction A network is simply a group of two or more Personal Computers linked together. Many types of networks exist, but the most common types of networks are Local-Area Networks (LANs), and Wide-Area Networks (WANs). In a LAN, computers are connected together within a “local” area (for example, an office or home). […]
