strokes on hosts at the network level. In this case‚ a thug generates a huge amount of ICMP ping requests (datagram) with fake source addresses and sends them to the IP broadcast address of a network‚ that is‚ remote LANs broadcast addresses. Then the routers/switch (layer 3) broadcasts these requests to layer 2 broadcast addresses. Most of the hosts connected to the network will then send reply for each of the echo. Thus‚ the network is overwhelmed by fake echo multiplied by the number of connected hosts

switches have essentially replaced repeating hubs in business environments. A conceptual software-driven special application of LAN switches‚ called Virtual LANs (VLANs)‚ was introduced in the mid-nineties with a lot of hype. They promised cost effective router-like benefits with the added advantage of reduced system administration costs. As we approached and then entered into the 21st century‚ other technological advances challenged the VLAN‚ and ultimately displaced it. This paper will builds the case

Failures in a Distributed System Paper Phyllis Lenoir POS/355 November 19‚ 2012 Asho Rao A distributed system is an application that executes a collection of protocols to coordinate the actions of multiple processes on a network‚ where all component work together to perform a single set of related tasks. A distributed system can be much larger and more powerful given the combined capabilities of the distributed components‚ than combinations of stand-alone systems. But it’s not easy - for a

This is where some of the problems start... Is this nice little nifty device only a Router? Or is there more behind it? To understand what this wonderful piece of technique is capable of we need to know a bit more about the different pieces a little home network is made of and how

devices such as hubs‚ repeaters‚ bridges‚ routers‚ switches‚ and gateways can be used to extend the LAN. Transmission media can include coaxial cable‚ twisted pair wiring‚ fiber cable‚ and radio waves. 1. For the desktop stations‚ you should consider Physical Ram for running the programs‚ Space on the hard drive for the software they would need to store‚ and processor strength for test running and for debugging. 2. For the Network you would consider routers for distribution of packets‚ bridges for

Case Study: Industry Sector: Configuration Review – Firewalls & Routers Media and Telecommunications Firewalls aim to provide organisations with reliable security at the network perimeter; however each firewall must be properly configured in order to allow and disallow network traffic accordingly‚ in a manner sensitive to business needs. Poorly configured firewalls can be overwhelmingly damaging to the security of an organisation – lax ingress rules may provide multiple vectors to attackers
