In the network application has been very popular today, gigabit network of popular applications are maturing, how to pick a good overall performance of the gigabit switch, both save money and apply, is very important. Especially for some original budget funds, the application of low demand for customers, both to meet the network transmission of high-speed, stable, and inexpensive, then in the selection of
-effectiveness of equipment should be fully considered to achieve the maximum ROI.
2. Upgrade the switch
Vswitches in an enterprise network are divided into three layers: Core-layer switches, aggregation-layer backbone switches, and access-layer workgroup switches ). As the hub of the entire network, almost 80% of network transmission is completed by the core switch. Therefore, the performance of the core switch determines the performance of the entire network. Therefore, when upgrading the netw

Therefore, the performance of the core switch determines the performance of the entire network. Therefore, when upgrading the network, you should first consider upgrading the core switch.

To upgrade a Gigabit Ethernet, you must first upgrade the network b

To improve the profitability of broadband network is to achieve the network can operate, manageable, the current key problem is that operators need to change the single monthly billing model, to provide different prices of differentiated services.

The network backbone uses network-managed fiber and copper Gigabit Ethernet technology to form a high-speed link channel. A second-level aggregation switch is a two-layer Gigabit Switch with network management capabilities.

Recently found around a lot of rice noodle friends, home since the ADSL upgrade to fiber optic network after a variety of slow speed. Today's small series to introduce how to improve and enhance the speed of the millet router. In short, it is how to let the cat and computer can match the millet router gigabit network faster speed.
Now the fiber to the user a lot of network speed has reached 50M, or even some more than 100M or more.

Generally, the calculation method is as follows:
1) wire speed backboard bandwidth
Measure the test taker's knowledge about the total bandwidth provided by all ports on the vswitch. The formula is as follows: number of ports * corresponding port rate * 2 (full duplex mode). If the total bandwidth is less than or equal to the nominal backboard bandwidth, the bandwidth is linear.
2) Layer 2 packet forwarding speed
Layer 2 packet forwarding rate = number of Gig
In the early 1990s s, with the improvement of computer performance and the increase of communication traffic, traditional local area networks have already surpassed their own load, and the emergence of switched Ethernet Technology, this significantly improves LAN performance. Compared with the current LAN topology based on bridges and routers, network switches can significantly increase bandwidth, while the addition of exchange technology can create a geographically dispersed network, the Applic
Category-6 Cabling systems are common cabling systems. They are also very important in cabling systems. Why can the category-6 Cabling systems develop so well, and the category-6 Cabling systems are mainly oriented to those groups, I believe you will have a deeper understanding after reading this article.
With the development of network technology, Gigabit to desktop has become a fact, and cat6 cabling systems have become more and more popular among u

With the development of network technology, gigabit to the desktop has become a fact, six of the wiring has been more and more users of widespread concern. However, in the current market, people have a lot of different understanding of the installation of six kinds of wiring.
Many manufacturers to gain market share, wishful thinking ground to all projects to promote six types of wiring, but not fully consider for the end user to provide a reasonable

Category 5. Category 6, Category 6, and category 7 are basically self-styled by manufacturers. Because more than five categories of standards have already been introduced, some manufacturers have produced a type of technical indicator that is better than five categories, and 6 categories of Self-sealing; due to market competition, other manufacturers have produced a network cable that is higher than the "6 categories" Technical indicator, so it has to block itself into more than 6 categories.
