Open Source License AgreementLicense is a license to the software that gives you the right to get the code, what you can do with other people's work, and what kind of actions are prohibited.Types of Open Source agreementsThere are many open source agreements that exist today, and there are currently more than 60 kinds of http://www.opensource.org/licenses/alphabetical approved by open source Initiative organization. Our common open source agreements such as BSD, GPL, lgpl,mit, etc. are all OSI-a

-------------------- Delegation mode-categories, protocols, and blocks Delegate. What is a delegate? XXX is a common form of entrusting people to do things. From here we can know that the entrusting is done by both parties. The delegation in OC is often used together with the protocol. The definition of delegation is the design pattern that one class specifies another class to process certain tasks. These days I have learned about classes,

. RTCP itself does not provide data encryption or identity authentication. Srtcp can be used for such purposes.SRTP srtcp references Rfc3711 Secure real-time transmission protocol (secure real-time transport protocol or SRTP) is a protocol defined based on the real-time transport protocol or RTP, the aim is to provide encryption, message authentication, integrity assurance and replay protection for data in real-time transmission protocols in unicast

Starting from this article, we will introduce some Bluetooth profiles and protocol as an entry-level reader. For details, refer: Bluetooth SIG Bluetooth Wiki The instructions on how to use Bluetooth devices are handed over to the above-mentioned websites. This site is committed to clarifying the technical specifications of protocols and profiles. First, the architecture of the Bluetooth protocol layer is described in this document. Host and Control

Common mail service protocols: POP3, IMAP, EXCHANGE, and imapexchange Some time ago I did mailbox client development, involving protocol support issues. By the way, I learned several major protocols: Generally, before setting up a mailbox on a mobile client, you 'd better know which protocol is supported by your mailbox. The common protocols include the following

This section briefly introduces the internal structure of TCP/IP and lays the foundation for discussing Internet-related security issues. TCP/IP protocol groups are popular in part because they can be used on a variety of channels and underlying protocols (such as T1 and X.25, Ethernet, and RS-232 serial interfaces. Specifically, TCP/IP is a set of protocols, including TCP and IP, UDP (User datainprotocol),

Comparison of five open source protocols (Bsd,apache,gpl,lgpl,mit). When a series of giants such as Adobe, Microsoft and Sun begin to show their preference for "open source", the era of "open source" is coming! There are many open source protocols available today, and there are currently 58 (http://www.opensource.org/licenses/alphabetical) of open source agreements approved by the Open Source Initiative o

that some commands are sequential, but most commands do not have this requirement. 3,RTSP can be said that the basic reuse of the design idea of HTTP, from the request and response message composition can be clearly seen. But it also borrowed from the relevant good ideas in FTP. such as the separation of data and control, RTSP data transmission is by RTP/RTCP and other protocols to achieve. In HTTP, the request response pattern is based on the CS mod

Preface Since Richard Stallman founded Free Software found in 1985, open source has sprung up and has been developing in full swing. Small to a Java or JS component and a Linux operating system. Open-source software has evolved from only open-source software to more features such as innovation, compilation, fast, and elasticity. Of course, open-source freedom does not mean that there is no limit at all. Different open-source software has different open-source

A very important feature of Bluetooth is that all Bluetooth products do not need to implement all Bluetooth specifications. To make it easier to maintain compatibility between bluetooth devices, the profile is defined in the Bluetooth specification. Profile defines how a device implements a connection or application. You can understand profile as a connection layer or application layer protocol.(1) The Bluetooth host controller module, as the underlying layer of Bluetooth, is a typical hardware

Http://inthirties.com: 90/viewthread. jsp? Tid = 1396 frombbs = 1 Today, a former company colleague asked me about the types of open source protocols. Common open-source protocols include GPL, lgpl, Apache, and BSD. Some special Java open-source projects do not fully comply with the mainstream open-source protocols.Note. Therefore, when choosing your own technical framework and introducing open-source pac

HTTP vs TCP/IPthe TCP (transmission Control Protocol) and UDP (User Datagram Protocol) protocols belong toTransport Layeragreement. Where TCP provides data in an IP environmentReliable transmission, it provides services that includeData flowtransmission, reliability, effective flow control, full-duplex operation, and multiplexing. Through connection-oriented, end-to-end, and reliableData packagesent. Popularly said, it is to send the data in advance t

Here we will introduce the IPv6 network protocol. This protocol is an upgraded version of IPv4. However, at present, the Internet is in an excessive phase of Two-Protocol handover, which leads to an important problem-security. In this unstable situation, security vulnerabilities may easily occur. How can we prevent them? First, let's take a look at some basic knowledge about IPv6 network protocols. You may know what are the main factors driving IPv6 a

At present, the development of the routing protocol is very rapid, so I have studied the introduction of the routing protocol, here to share with you, hope to be useful to everyone. With the rapid development of the Internet, TCP/IP has become the mainstream protocol for data network interconnection. Vrouters running on various networks are responsible for controlling traffic that may be the most important information of this century. The collaboration between hundreds of vrouters is inseparable

For network security, this is a more complex structure and engineering. Many factors can affect our network environment. In the network, we define various network security protocols for effective protection. Next we will compare and analyze different protocols. SSL and IPSec (1) SSL protects the security of data transmitted on the transport layer. In addition, IPSec also protects the security of data packet

There are many small details about the routing protocol, which deserves our attention. There are also many categories that indicate the different functions of different routing protocols. Now we will talk about the routing information protocol. For more information about the specific functions and features of this protocol, refer to them. The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). In 1981, the rou

This article mainly introduces the self-organizing network routing protocols used in the self-group network. This article gives some specific instructions on these protocols, I believe that reading this article will help you. The cluster head gateway switch routing (CGSR) protocol is designed based on the DSDV protocol and the hierarchical routing mechanism. CGSR uses the least clusterchange (LOC) algorithm

Application Layer functions and Protocols 1. In the application layer, software programs or processes access the network in two forms: applications and services. Applications can interact with us. Is the user software. If the device is a computer, the application is usually started by the user. Although there are many levels of support below, the application software provides interfaces between people and hardware. When you click the send button or pe

This article mainly introduces a simple WebSocket server that is compatible with the old and new Socket protocols in Python, if you need it, you can refer to the WebSocket technology introduced in HTML5 that needs to be used in a recent project. I thought it would be easy to handle it, who knows that there are a lot of troubles after the development is really started? although we are a long-experienced team in development and design, we have never bee
