MAC Protocols And CSMA/CD

We will talk about MAC protocols and Ethernet technology, both operating at the lowest two layers of the OSI model, which corresponds to the Link layer in TCP/IP. Shared Ethernet In 10Base-2 and 10Base-5 networks, hosts share the same medium of communication. Hosts on a shared Ethernet network physically connect to Read more…

Multicast Routing Algorithms

In this article I’ll expose each multicast routing algorithm that I studied: Flooding, Spanning-Tree, RPB and RPM. Flooding Flooding is the most basic multicast routing algorithm. The way it works is as follows: the router receives a multicast packet on interface Int1 if the packet is “seen” for the first time, Read more…

Autonomous Systems, IGP and EGP

 Interior Gateway Protocols IGP Interior Gateway Protocols are the protocols that run inside an autonomous system. IGPs are all (or most) of the protocols you learned in school (or later in your career): RIP, OSPF, EIGRP, IS-IS,… IGP can be redistributed into EGPs. Exterior Gateway Protocols EGP An exterior gateway Read more…
