IEEE and 10GEA (Gigabit Ethernet Alliance) are the two most important organizations in Gigabit Ethernet standardization.Gigabit Ethernet standards and specifications are many, in the standard, the first 2002 years of IEEE 802.3ae, and then continue to have a new Gigabit Ethernet specification, such as the 2006 IEEE 802

First, the purpose of the experimentCompare the performance of shared Ethernet and switched Ethernet over different network sizes.Second, the experimental methodUse Opnet to create and simulate a network topology, and run to analyze its performance.Iii. contents of the experiment3.1 Experiment settings (network topology, parameter settings, data to be observed, etc.)Step 1: Download the It Guru, create a ne

In the previous article we introduced the Ethernet 5 layer model, which I want to learn about the encapsulation and unpacking of Ethernet data, and how Ethernet data is transmitted. First, data encapsulation when our application uses TCP to transmit data, the data is fed into the protocol stack, then passes through each layer one by one, knowing that the final to

Go-ethereum The Go-ethereum client is often referred to as the Geth, which is a command-line interface that executes the complete etheric square node that is implemented on the go. By installing and running the Geth, you can participate in the real-time network of the front desk of the ether and do the following: Mining the real etheric currency transfer funds between different addresses create contracts, send deals to explore block history and many other Links: Sites: Http://ethereum.github.io

Prerequisite: The following involved in the content of the need for system permissions, that is, system applications, development of non-system app is Rao edge. Ethernet settings are generally entered into the system native Settings app, into the Ethernet option to set. In some special occasions, the need to customize the app, do not directly call the system settings, then you have to implement the

Http://blog.csdn.net/sailor_8318/article/details/3907345 Differences between switched Ethernet and shared Ethernet A hub, also known as a hub, belongs to the data link layer in the OSI model. However, as the hub is a shared-bandwidth device, the efficiency of the hub becomes very low in the heavy network and is prone to broadcast storms. Therefore, we cannot see hubs in medium and large networks. A vswi

IEEE has just approved the Ethernet P802.3az Energy Sensing standard, which reduces the energy consumption of networked devices while they are running. Reducing energy consumption is the next goal of information and communication technology managers in order to spend less money and work more, energy-efficient Ethernet can save energy and reduce operating costs. This new standard network, in most cases, au

Static and Dynamic Ethernet Switching Technology There are many types of Ethernet Switching Technology, each of which has its own advantages. You can use a simple mouse to increase, move, and change the structure of the exchange; network segments are more effective than bridges and routers; high bandwidth is provided for high-performance workstations or servers. Network managers are eager to use these techn

Ethernet switches are still commonly used. So I studied Ethernet switches and their devices. I would like to share them with you here. I hope they will be useful to you. Ethernet is the most widely used in L2 switches ). At present, more than 90% of local area networks around the world use Ethernet technology. With the
