Bitcoin Trading A transaction is composed of some inputs and outputs (output): type Transaction struct { ID []byte Vin []TXInput Vout []TXOutput} For each new transaction, its input will refer to the output of a previous trade (reference) (here is an exception, the Coinbase deal we will

MPLS Multiprotocol Label Switching-Multi-Protocol Label exchange technology is a new technology that uses tags to guide high-speed and efficient data transmission on open communication networks. Its value lies in its ability to introduce the connection mode in a connectionless network. Its main advantage is that it reduces network complexity, is compatible with various mainstream network technologies, and can reduce network costs by 50%, ensure QoS and security when providing IP services, and ha

Test cases are rarely so simple. The following is a more practical example of a test case generated by the test case. Example: The main character and use case of an ATM m

In the course of the development of IPOA technology, CIPOA (Classic IPOA, that is, traditional lP on ATM), LANE (LAN simulation), and MPOA (Multi-Protocol Transmission on ATM) emerged one after another) IP address switching, CSR (cell Switch Router technology), ARIS (Integrated IP address switching technology), TapSwitching (Label Switching Technology), MPLS and other technologies. These IPOA technologies c

1. Significance of MPLS　　 Traditional IP data forwarding is based on the hop-by-hop mode. Each router that forwards data needs to find the route table based on the destination IP address of the IP address header to obtain the next hop egress, this is a tedious and inefficient task, mainly because of two reasons: 1. Some route queries must perform multiple searches on the route table, which is called recursive search; 2. Because route matching follows the longest Match Principle, almost all vro s

easily create more robust web applications. To highlight how a transaction enhances a Web application, a common example is the ATM that the Web browser interacts with the client. 　　ATM Sample: 　　Scenario This example is simpler: a customer wants to withdraw from an ATM, enter his customer name, John_doe, and the number of withdrawals, $. If he had enough money o

QoS Problem AnalysisCurrently, the public exchange Telephone Network (PSTN) and ATM network can ensure the service quality, while the IP network cannot guarantee the service quality. Therefore, in this section, we analyze the service quality problems of IP networks by comparing the PSTN and ATM technologies and networks. First, let's take a look at the service quality of the PSTN network.　　In PSTN, networks

This is GitHub's repo, so go ahead and fork it (if you don't want to copy and paste all the code), and if you have an update that you want to share, I'll put it in the Readme file. private block chain creation To create a separate node, you need the following Genesis.json code, which represents the initial block on the private block chain. //genesis.js

Among our commonly used devices, one is a router and the other is a switch. These two types of devices are all important for network management. So today we will give a brief introduction to the relevant content of the IP switch. These include GSMP and IFMP. To master the GSMP and IFMP protocols, we need to understand the concept of IP exchange. Next, let's take a look at the basic concepts of IP exchange. Basic concepts of IP address exchange IP exchange technology was first proposed by Ipsilon

We also often deal with ATM in our daily life. In th

Only the person with the right private key can create a legitimate signature, which guarantees that the money can only be spent by the owner.Each output defines which address (or other criteria, see the "Digital currency script" article) is the recipient of the funds.In a transaction, the sum of all the inputs must be equal to or greater than the sum of all the outputs, and if the input exceeds the output, the excess is the transfer fee, and whoev

IEEE802.3AH Working Group and Itu/fsan respectively.Epon is an Ethernet-based passive optical network that combines Ethernet technology with PON technology to provide up-and-down symmetrical 1.25gbit/s line transmission rates to achieve a point-to-multipoint structure of the Gigabit Ethernet fiber access system.The Gpon technical feature is the encapsulation mapping of various services such as Ethernet, TDM, ATM, and 1.25gbit/s in two layers using th

It is very useful to learn about the cell packaging technology. So I studied the cell Packaging Technology in Cisco routers. I will share it with you here, hoping it will be useful to you. Cell packaging, also known as cell concatenation) is a mechanism that encapsulates multiple cell relay asynchronous transmission modes (ATM) cells into the same IP/MPLS group. It enables telecom operators to overcome the low bandwidth efficiency inherent in cell rel

Ten years ago in China, ATM was a very new thing, which is now everywhere in the streets and alleys of the city. We often deal with ATM in our daily lives. In this chapter, we will use the simplified ATM system as an example to apply the knowledge of the use case diagram, class diagram, sequence diagram, state diagram, activity diagram, and collaboration diagram

First, the Network Exchange technology development process 1. Circuit Switching Technology Network switching technology has undergone four stages of development, such as circuit switching, packet switching, packet switching and ATM technology. Public telephone Network (PSTN) and mobile networks (including GSM network and CDMA network) are all circuit switching technology, its basic feature is the use of connection-oriented approach, before the two s

the next generation network should be based on the quality of IP-guaranteed Universal telecommunications network. The development of the customer of the network needs not only the optimization of the existing network service, such as the QoS guarantee of the connectionless Network service and the IP service. At the same time, the smooth transition of existing network service and physical Foundation also needs good planning. Although it is very complicated to realize the exchange of multiple ser

MPLSMultiprotocol Label Switch (MPLSMultiprotocol Label Switch) was originally proposed to speed up router forwarding, but because MPLS is used in Traffic engineering Traffic Engeering) and VPN are two key technologies in the current IP network. MPLS has become an important standard for expanding the IP network scale. The key to MPLS protocol is to introduce the Label Concept. It is a short and easy-to-process information that does not contain topology information and only has local meaning. Lab
