Ethernet is the world's most pervasive networking technology. Gigabit Ethernet is the latest version of Ethernet. It offers 1000 Mbps ( 1 Gbps ) raw bandwidth, that is 100 times faster than the original Ethernet, yet is compatible with existing Ethernets, as it uses thesame CSMA/CD and MAC protocols. When Gigabit Ethernet enters themarket it will compete directly with ATM. 2 Ethernet — An Introduction to Computer Networks, edition 2 Ethernet¶. We now turn to a deeper analysis of the ubiquitous Ethernet LAN protocol. Current user-level Ethernet today (2013) is usually 100 Mbps, with Gigabit and 10 Gigabit Ethernet standard in server rooms and backbones, but because the potential for collisions makes Ethernet speeds scale in odd ways, we will start with the 10 Mbps formulation. Ethernet - highteck.net Slot time for 10- and 100-Mbps Ethernet is 512 bit times, or 64 octets. Slot time for 1000-Mbps Ethernet is 4096 bit times, or 512 octets. The slot time ensures that if a collision is going to occur, it will be detected within the first 512 bits (4096 for Gigabit Ethernet) of the frame transmission. Solved: 1) Consider A Slotted Ring Of Length 20 Km With A 1) Consider a slotted ring of length 20 km with a data rate of100 Mbps and 1000 repeaters, each of which introduces a 1-bitdelay. Each slot contains room for one source address byte,one destination address byte, two data bytes, and 8 control bitsfor a total length of 40 bits.

Each station is assigned one time slot per cycle for transmission. For the bus, the length of each slot is the time to transmit 100 bits plus the end-to-end propagation delay. For the ring, assume a delay of 1 bit time per station, and assume that a round-robin assignment is used. Stations monitor all time slots for reception. 2 Ethernet — An Introduction to Computer Networks 2 Ethernet¶. We now turn to a deeper analysis of the ubiquitous Ethernet LAN protocol.

What does 10/100/1000 Ethernet port mean? - Quora For example your ethernet port is 10/100/1000, but you are using a utp or stp cable that can only carry 100mbps at that time your port is works as 100mbps, but if you are going to use a cable that can handle 1000 mbps like cat6 or cat5e cable at that time your port can send data about 1000mbps.
