Introduction to Ethernet, Fast Ethernet, Gigabit Ethernet
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. Ethernet MAC: CSMA/CD - Purdue University CS 422 Park Worst-case collision scenario: •sender needs to wait 2τ sec before detecting collision •for 2500 m length, 51.2 µs round-trip time (2τ) •enforce 51.2 µs slot time •at 10 Mbps, 512 bits; i.e., minimum frame size →assures collision detection Assignment 2 - darkandtwisted.com 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¶. 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 Ethernet standard in server rooms and backbones, but because Ethernet speed scales in odd ways, we will start with the 10 Mbps formulation.
In a area where the average speed was a 6 Mbps DSL connection or possibly a 20 Mbps cable Internet plan then 100 Mbps would be considered fast. In a major metropolitan area with access to Gigabit Internet services such as Google Fiber, Comcast Gigabit Pro, or Cox Gigablast Internet,then 100 Mbps would be considered slow.

Free delivery and free returns on eBay Plus items! what is the slot time in half-duplex ethernet timing ... The slot time is determined by the physical size (distance) the network covers. In original 10Mbps Ethernet the slot time is 51.2 microseconds, in 100 Mbps Fast Ethernet which is 10x faster, the slot time is 10x smaller or 5.12 microseconds. These are both based on 512-bit slot times. Consider An Ethernet Of 100 Mbps With CSMA/CD Is U... | Chegg.com

Managed Industrial Gigabit Switch Extreme Temp | Black Box The 4 Slot Industrial Gigabit Ethernet Switch managed Modular Chassis comes with a standard 5 Year Double Diamond™ Warranty (Standard) already included. During the warranty period, Black Box Network Services will repair or replace your damaged equipment within one week of receipt at NO CHARGE!* 10-Mbps and 100-Mbps Ethernet - basicitnetworking.blogspot.com For example, 1 bit time at 10 Mbps = 100 nanoseconds (ns) = 0.1 microseconds = 1 10-millionth of a second. This means that on a 10-Mbps Ethernet network, 1 bit at the MAC sublayer requires 100 ns to transmit. For all speeds of Ethernet transmission 1000 Mbps or slower, transmission can be no slower than the slot time. How Much Internet Speed Should You Really Pay For? - Tom's Guide
