Ethernet - (3)

Ethernet - (3)

Summary on What we have studied in last Tutorial ? :-

• 1000Base-X is the first version published by the 802.3z standard. It is divided into a number of standards such as 1000Base-CX, 1000Base-SX and, 1000Base-LX.
• Gigabit Ethernet Provides speed of 1000Mbps.
•  It transmits data over UTP category 5e, or 6 cabling.Gigabit Ethernet is divided into following standards.

(1.2.1) Advantages of Gigabit Ethernet :-

• Compatibility - Gigabit Ethernet uses same transmission schemes and Frames format as they are used in 100Base-T and 100Base-T ( Fast Ethernet ) Ethernet. As a result, there is no need of complex, slow emulations and translations for Gigabit Ethernet.
• Hardware Cost - The Hardware cost of Gigabit Ethernet is equivalent to the Cost of Tradtional Ethernet and Fast Ethernet hardware.
• Familiar Technology - Gigabit Ethernet is supports the same technology and uses the same protocols as used in Ethernet and Fast Ethernet.
• Straight Forward Management - The management System established for Ethernet and Fast Ethernet can be used for Gigabit Ethernet.
• Staff training - Gigabit Ethernet requires minimal staff training as it uses the same design, installation, and configuration that are used for Ethernet and Fast Ethernet.
• Working Distance - The Gigabit Ethernet over fiber has a working distance of upto 5 Kilometer.
• Speed - The Gigabit Ethernet provides upto 1000 Mbps of data rate which is 10 times faster than 100Base-T Ethernet.

(1.2.2) Disadvantages of Gigabit Ethernet :-

• Low Bandwidth Utilisation - The theoretical Bandwidth of the Gigabit Ethernet is 1000 Mbps. But practically, its Bandwidth utilisation is up to 900 Mbps.
• Expensive - Fibre based Gigabit Ethernet is Comparatively costlier and employs Complex lasers as the light source which further add up to the cost.

(1.3) 10-Gigabit Ethernet :-

      10-Gigabit Ethernet or 10 Gbe is the most recent and Fastest Ethernet standards. It was developed by IEEE 802.3ae in 2002.
      

       It is ten times (10x) faster than Gigabit Ethernet. It uses full Duplex mode of Transmission and most run on Fiber. LANs, MANs, & WANs can be interconnected using 10-Gigabit Ethernet. It supports a segment length up to 40 kilometres. It uses Media Access Control (MAC) protocol.

(1.3.1) Advantages of 10-Gigabit Ethernet :-

• Mode of Operation - Uses full Duplex mode of Data Communication. As a result operations are simplified and collision-detection protocols which were used in previous forms of Ethernet are not required.

• Quality and Security - Provides High security and quality. It also provides increased flexibility for linking other network devices over longer distances.

• Compatibility - 10-Gigabit Ethernet communication standards are fully compatible with existing Ethernet standards.

• Convergence Opportunities - Present 10-Gigabit Ethernet can carry integerated voice and data across broader networks without modification.

• Ease of Implementation - Uses the basic feature of Ethernet. As a result, it can be implemented without training the staff for Ethernet standard.
