Objective-C Protocols, objective-c Objective-C Protocols 1.1 Formal Protocols A formal protocol (like an informal protocol) is a named list of methods and properties. Formal protocol (like informal protocol) is a list of names of a series of methods and attributes. However, a formal protocol requires that you explicitly adopt it. Formal protocol requires you to e

route table of "inter-network. The routing action includes two basic items: path finding and forwarding. The routing algorithm is used to determine the optimal path to the destination. Because different routing protocols and routing algorithms are involved, it is relatively

Many people may not know much about the OSPF routing protocol. Here we will mainly explain the detailed introduction of the OSPF routing protocol. Here we will share it with you and hope it will be useful to you. Link State packet type in the region: 1. Router LSA It is generated by all vrouters in the region and can only be broadcast in flood scenarios in the region. 2. Network LSA Generated by the DR or B

The Magento routing system requires two layers of abstraction to be considered.1, first you need to understand that there may be countless multiple routing objects that are responsible for handling routing logic, and finally only one routing object can get and process the request. By default, Magento has four route obj

Common network protocols in browsers In fact, browsers need to deal with various network protocols to complete various WEB application functions. HTTP is only one of them. This article describes common network protocols in browsers and their relationships. We often hear the term "TCP/IP protocol". Literally, some people think that it refers to both TCP and IP

There was no clear concept of open-source protocols before, and I always thought that open-source is free or even free of charge. I spent a day reading open-source protocols a few days ago. Common Open Source protocol analysis Let's have a look at 'open source! Common Open Source protocols Sun shot GPL open source Protocol Open source protocol list I also read so

I have learned some useful knowledge about dynamic routing protocols. So I have studied the application of dynamic routing protocols in the network communication industry. I will share with you here, I hope it will be useful to you. Interconnect Networks use routes to send data from one network to another. In computer

call establishment. At this time, each Softswitch only contacts the corresponding locating server, and the locating server locates the destination Softswitch Network. In this case, the softswitch stores the complete routing information of the user in the control range and the routing information between the softswitch in the same domain. At the same time, you can also consider establishing a local ing libr

URL Routing (Routing) has two main uses in ASP. NET MVC, one purpose is to match the HTTP request from the browser, and the other is to respond to the appropriate URL to the browser .3.1 Matching HTTP requests coming through the browserFirst, let's take a look at the first use, which is to match the HTTP request coming from the browser.When a client makes a request to an ASP.

Recently, a colleague in the study Angularjs, in Routing and template learning process encountered some problems, so today she wrote an example, by the way to share out to those who are learning ANGULARJS partners. This ANGULARJS development project is very cool, which cool on the development of its model, making the code more clear, more readable, more concise, more maintenance. But in the process of using ANGULARJS development has also made me a he

First, Web applications　　A Web application is an application that can be accessed through the web;The biggest benefit of the program is that the user has easy access to the application, and the user needs only a browser and no additional software to install.There are two modes of application: C/S,/b.1, c/S is a client/server-side program, which means that such programs generally run independently.2, b/S is browser-side/server-side applications, such applications generally with the help of Google

The HTTP protocol defines eight methods or "actions" to indicate different ways to manipulate the resources specified by the Request-uri.The details are as follows:OPTIONS: Returns the HTTP request method that the server supports for a specific resource. You can also test the functionality of your server with a request to send a ' * ' to the Web server.HEAD: Ask the server for a response that is consistent with the GET request, except that the response body will not be returned. This method allo

Simple Network Management Protocol (Snmp:simple Network Management Protocol). The Simple Network Management Protocol is the SNMP protocol that we often refer to as a set of network management protocols defined by the Internet Engineering Task Force (ietf:internet Engineering task Force). The protocol is based on the Simple Gateway Monitoring Protocol (Sgmp:simple Gateway Monitor Protocol). With SNMP, a management workstation can remotely manage all ne

HTTP is only responsible for transmitting the data in the past, not the data is XML, HTML, pictures, text files or anything else. and the SOAP protocol defines how to make an object into XML text, how to call it in a remote way, and how to confuse it.Two kinds of protocols are said:HTTP is the Post Office Protocol, they specify how you want your envelopes to be written, how many stamps to paste, etc...Soap is the agreement between you and the person w

When using X and S locks to lock data objects, some rules need to be agreed, such as when to apply for an X lock or S lock, hold the lock time, and when to release. Called these rules for the blockade agreement (locking Protocol). The different rules governing the blockade form a variety of blockade agreements. Different blocking protocols provide certain guarantee for the correct dispatch of concurrent operation to different extent. 一、一级 Blockade Pr

The difference between get and post requests. 1, when the browser fallback and refresh, get harmless, but post will resubmit the data 2, get can be bookmarked, and post can not 3, get can be cached by the browser, and post can not 4. The encoding type of the GET request is application/x-www-form-urlencoded The encoding type of the POST request can be application/x-www-form-urlencoded and multipart/form-data 5, get parameters for the existence of browsing history, and post does not 6, get the url

transaction to be modified at all.Two-stage lock protocolThe database follows the "two-segment lock" protocol when scheduling concurrent transactions, which means that all transactions must lock and unlock data items in two stages Extended stage: Before you read or write any data item, apply and obtain a blockade of the data item. Shrink stage: In each transaction, all blocking requests must precede the unlock request. Mathematically, it can be proved that the scheduling with

Q: What are the NetBEUI and IPX/SPX TCP/IP protocols ?? In particular, the first two are sometimes installed, and sometimes they are not installed. Why ?? What are their differences and uniqueness? When must I install it? A: A lot of netizens asked this question. I have consulted and integrated the relevant information here to give you a detailed explanation. The network Protocol is a special software and the most basic mechanism for a computer networ

Next-generation protocols related to IPv6 are in the TCP/IP protocol set. Protocols that are directly active and indirectly interoperable with IP addresses include various application layer protocols, connection protocols, and TCP and UDP. This chapter will discuss the impact of IPv6 on other layer
