Data backhaul between Android pagesRequirements: Page 1 jump to page 2, page 2 and return to page 1 also return dataPage 1 adds the following code:Intent Intent = new Intent (); Intent.setclass (page 1.this, page 2.class); Bundle bundle = new bundle (); Intent.putextras (bundle);//Add bundles to intent, or you can add data from bundles to the next page, for example: Bundle.putstring ("abc", "BBB"); Startactivityforresult (Intent, 0);//jump and

branch network structure, the noise and intrusion interference from the user and the network are at the front end of the cable network, that is, the roots of the network are converged together. For the backhaul channel, the noise components produced by each amplifier are all gathered at the front end of the access network system. This noise component is proportional to the size of the access network system, it is proportional to the number of upstrea

Ethernet (Ethernet) Ethernet Ethernet (Ethernet) is a computer LAN networking technology. The IEEE 802.3 standard developed by IEEE gives the technical standard of Ethernet, which specifies the contents of the connection, the ele

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

interfaces. Generally, the downlink speed is no more than 20 M. In practice, the distance is controlled at around 2km, which is a typical "last mile" access. PON: optical fiber access mode with a wide range of ONU interfaces. It can provide interfaces such as FE, GE, and POTS. The uplink bandwidth can be dynamically allocated and is related to the split ratio. The value is calculated equally at, and each branch is about MB. The downstream bandwidth depends on the system load, and a single user

In the absence of dynamic routing such as OSPF A->b, a must know how to get to B so there should be a route for B on a. When A's packet arrives b,b needs to respond, so B should know how to get to a. Therefore, a route must be reached on B.

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn

Ethernet switches are expanding their applications to the network core. This is mainly from two aspects: one is that Ethernet switches have the function of routers, not even, there are more than three layers of switches; the second is the maturity of the physical layer technology and the Exchange technology makes the Ethernet break through the area of the LAN, an

The main network elements in the Ethernet network include switches, routers, firewalls, servers, and clients. By testing the Ethernet network elements and the network itself, the network structure can be optimized, the network fault is eliminated and the network performance is mastered. Ethernet testing is also rule-based, such as the well-known rfc2544/rfc1242,

Whether from the demand side or from the supply side, the overall network is moving towards broadband, which gives Ethernet a good space for development. From a technical point of view, over the past 20 years, Ethernet bandwidth from 10 trillion, hundred trillion, gigabit, has been developed to 2002 million trillion, or even 40,000 trillion, 100,000 trillion are already in the research and discussion stage,
