sdn protocols

There are many open-source protocols today, and there are currently 58 open-source protocols approved by the Open Source Initiative Organization (http://www.opensource.org/licenses/alphabetical ). Common open-source protocols such as BSD, GPL, lgpl, and MIT are OSI-approved protocols. If you want to open your ownCode,

Objective-C Protocols, objective-c Objective-C allows you to define protocols, which declare the methods expected to be used for a particle situation. Protocols are implemented in the classes conforming to the protocol. A simple example wocould be a network URL handling class, it will have a protocol with methods like processCompleted delegate method that intimat

I. Overview 1.1 Five-layer model The realization of the Internet, divided into several layers. Each layer has its own function, like a building, each layer is supported by the next layer. What the user touches is just the top layer, and there is no sense of the layer below. To understand the Internet, you must start from the bottom and understand the function of each layer. There are different models for layering, and some models are divided into seven layers and some four layers. I think it

backbone network, people connected to it through the IPIP (IP Encapsulation IP) tunnel. The Unix program mrouted can understand the DVMRP and IGMP protocols, but the Internet Router cannot. Many customers who want to adopt Multicast technology are still asking their ISP why some protocols do not work. DVMRP refers to the distance vector multicast routing protocol. It uses IGMP subcode 13 and implements the

architecture 2. Switch application processing to Open Systems (Windows and Unix) 3. IP addresses are widely used as interconnection protocols None of these trends is surprising. Using the IP protocol, Intel-compatible open-system servers have dominated modern data centers. Given this dominant processing architecture, Ethernet Interconnection is a logical choice, and no other network protocols can occupy su

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

A Preliminary Study on WCF-16: Basic knowledge of WCF data protocols, wcf-16Data protocols "Data agreement" is a formal agreement between the service and the client, used to describe the data to be exchanged in an abstract way. That is to say, for communication, the client and service do not have to share the same type, but only need to share the same data protocol. Data

user; A call is initiated by a SIP user and terminated by a PSTN user. A call is initiated by a PSTN user and terminated by a SIP user. SIP-T provides two methods for intercommunication between SIP and ISUP, namely encapsulation and ing, which are defined by RFC3204 and RFC3398 respectively. However, the SIP-T only focuses on the intercommunication of basic calls, while the supplementary business is basically not involved. 2. ITU-T protocols for SIP-

The relationship between HTTP and TCPSimply put, the TCP protocol is the cornerstone of the HTTP protocol--http protocol needs to rely on the TCP protocol to transfer data.In the network layering model, TCP is called the Transport Layer protocol, and HTTP is called the application-layer protocol.There are many common application-layer

Recently made a terminal 5.0 platform, which uses a number of serialized protocols, such as XML,JSON,PROTOBUF, some places to use the feeling pretty good, some places use some inappropriate, and found that many open source is widely used in the serialization protocol, this is a basic prerequisite skills, so I would like to summarize, for the future architecture set The choice to do bedding;What is a serialization protocol? the serialization protocol i
