1. Introduction
The IEEE 802.3z Gigabit Ethernet Standard, adopted in June 1998, describes 3 physical layer interfaces (1000BASE-SX, 1000BASE-LX, and 1000BASE-CX) that are used for a universal link encoding and can be 1000mb/s transmitted. 1000BASE-SX, 1000BASE-LX interface using optical fiber as a medium, the farthest transmission distance of up to 5000 meters, so can be used in buildings or campus backbo
Gigabit all-optical Ethernet network
In view of CE's ability to replace SDH/MSTP and become a condition for mainstream next-generation transmission technologies, SDH/MSTP is considered to be part of the access layer in the 2G/3G base station backhaul network or ip man architecture. From this perspective, CE is a type of access network. CE access not only effectively avoids the defects of the preceding acce

Resolving network bottlenecks Gigabit Ethernet becomes the key
As IT departments add input/output-intensive and communication-intensive applications to servers, data center networks are facing a significant increase.
Systems installed around 1 GbE are no longer efficient; in many cases, replacement technology: 10 GbE is also a network bottleneck.
Fortunately, there are more than one way to clear up conges
Currently, the mainstream Gigabit Ethernet switches support up to four link aggregation groups and each group has up to four ports. We believe that with the development of the exchange industry, their functions will become more powerful. The best methods to identify the advantages and disadvantages of GE Ethernet switches include: the most direct indicators of fu
What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch?
How do I connect the four SFP ports of a d-link DGS 1248 t smart switch?
I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugged into a Gigabit
Solve the problem that Qualcomm Atheros AR8161 Gigabit Ethernet NIC fails in Linux.
The NIC Of My Dell I2330R-168 integrated computer broke down after upgrading a kernel version.
ifconfig eth0eth0: flags=4163
Now the arch linux is installed, and the kernel is updated to the latest version.

However, this problem still exists.
I suddenly thought tha
If the server has 4 Gigabit Ethernet cards, how would you choose to design a virtual network of VMware platforms?
First, let's look at this virtual network design diagram
Production business network requires the use of independent network segment resources, design is very fixed, it is not discussed
(production, vmotion and management networks can be isolated via VLANs (two tiers), or through routing is
The physical layer of Gigabit Ethernet is divided into the physical encoded child Layer PCs (physical coding sublayer), the physical Media Connection layer PMA (physical Medium attachment) and the physical media related child layer PMD (physical Medium Dependent) Three Floor
The PCS child layer is responsible for 8B10B encoding, which converts 8-bit parallel data received from Gmii to 10-bit parallel d
