Stainless Steel Press Fitting Pipe System Â
Gigabit Ethernet is built on top of the Ethernet standard technology. Gigabit Ethernet and heavily used Ethernet are fully compatible with Fast Ethernet and take advantage of all the technical specifications specified in the original Ethernet standard, including CSMA / CD protocol, Ethernet frame, full duplex, flow control, and IEEE802 .3 The management object defined in the standard. As an integral part of Ethernet, Gigabit Ethernet also supports traffic management technology, which guarantees quality of service over Ethernet, including IEEE 802.1P Layer 2 priority, Layer 3 priority QoS coding bits, and special Service and Resource Reservation Protocol (RSVP).

Gigabit Ethernet also uses IEEE 802.1QVLAN support, Layer 4 filtering, and Gigabit Layer 3 switching. Gigabit Ethernet was originally designed as an exchange technology, using fiber as an uplink for building connections. Later, in the server connection and the backbone network, Gigabit Ethernet is widely used, due to IEEE802.3ab standard (using Category 5 and above unshielded twisted pair Gigabit Ethernet standard) introduced, Gigabit Ethernet can Applicable to any small medium and large enterprises and institutions.
Gigabit Ethernet has evolved into mainstream network technology. Large to tens of thousands of large enterprises, small to dozens of small and medium enterprises, in the construction of enterprise LAN will Gigabit Ethernet technology as the preferred high-speed network technology. Gigabit Ethernet technology is even replacing ATM technology, the main force to build metropolitan area network.
1. Gigabit Ethernet provides a seamless migration path that fully protects investments in existing network infrastructures. Gigabit Ethernet will retain IEEE802.3 and Ethernet frame format and 802.3 managed object specifications, enabling enterprises to upgrade to Gigabit performance while maintaining existing cables, operating systems, protocols, desktop applications Procedures and network management strategies and tools;
2. Gigabit Ethernet provides an optimal path over the original Fast Ethernet, FDDI, ATM and other backbone solutions. At least for now, it is a reliable and economical way to improve the connection between the switch and the switch between the switch and the switch and the server. Network designers can build high-speed infrastructure that effectively uses high-speed, mission-critical applications and file backups. Network administrators will provide users with faster access to the Internet, Intranet, metro and WAN.
3. The IEEE 802.3 Working Group established the 802.3z and 802.3ab Gigabit Ethernet workgroups whose mission is to develop Gigabit Ethernet standards that meet different needs. The standard supports full-duplex and half-duplex 1000Mbps, the corresponding operation using IEEE 802.3 Ethernet frame format and CSMA / CD media access control method. Gigabit Ethernet is also backwards compatible with 10BaseT and 100BaseT. In addition, the IEEE standard will support multi-mode fiber with a maximum distance of 550 meters, a single-mode fiber with a maximum distance of 70 km and a copper shaft cable with a maximum distance of 100 meters. Gigabit Ethernet fills the 802.3 Ethernet / Fast Ethernet standard
