VPN protocols: PPTP, L2TP, and OpenVPN1. Concepts of PPTP, L2TP, and OpenVPN Tunneling Protocols 1. Default port number of PPTP (Point to Point Tunneling Protocol): 1723 PPTP, or PPTF Protocol. This protocol is a new enhanced security protocol developed on the basis of the PPP protocol. It supports multi-protocol Virtual Private Network (VPN) and can pass the password authentication protocol (PAP) and Exten
MPLS routing protocol is one of the most common protocols in the process of using a router. Many people may not understand the basic concepts of MPLS routing protocol. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. MPLS routing protocol (Multiprotocol Label Switch) was initially proposed to speed up the forwarding of the router, but because MPLS is used in the Traf
When it comes to routing, users generally understand its role. However, as IT workers, IT is not enough to simply understand its role. We also need to understand the routing protocol and its classification. Now let's take a detailed summary of the classification of this routing protocol. First, let's take a look at its basic content. Classification of routing protocols Typical routing methods include Static Routing and dynamic routing. Static Routing
The previous article described how to customize the protocol for the application, so a friend would ask, I want to register multiple protocols for my app, different protocols to handle different things, can I? The answer is yes.method is mainly on the configuration manifest file, here I give an example, the sample application will register two protocols, respecti

XMPP and xmpp protocolsXMPP-instant messaging technology Overview (IM -- Instant Messaging) supports real-time online conversations. If you want to send a message, you need to open a small window so that users and their friends can enter the information and both parties can see that there are many IM systems in the conversation content, for example, AOL, Yahoo IM, MSN, and QQ, the biggest difference lies in the implementation of their respective communication
commandNetstat-pan|grep 80NETSTAT [-A] [-b] [-e] [-n] [-O] [-P proto] [-r] [-S] [-v] [interval]-a displays all connections and listening ports.-B Displays the executable components that are included in creating each connection or listening port. In some cases, the executable component is known to have multiple independent components, and in these cases a sequence of components that are included in creating a connection or listening port is displayed.

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
