osi protocol stack

In the development of wireless communication, our current standard is the WAP protocol stack. In order to make everyone better understand this content. Now we will give a detailed introduction to the relevant content of this agreement. Let's first understand the meaning of WAP. WAP (Wireless Communication Protocol) is used on digital mobile phones, the internet,

We all know the necessity of using the IPv6 protocol stack. In the face of increasing network pressure, we have to raise higher standards to meet the needs of more users. What are the characteristics of this next-generation network? Now let's take a closer look at the IPv6 protocol stack. IPv6

Domain Name system, request in or response in will tell which message number matches.3.2 Other TCP message segmentsOther TCP segments, either TCP connections or data transfers, are easy to analyze according to the TCP Protocol (TCP message format + three handshake instance), which is deeply understood in conjunction with the Wireshark capture packet for the TCP/IP protocol

Linux Network protocol stack implementation is accurate but not yet delicate, needless to say netfilter, just said TC is enough, but there are several shortcomings, this article to do an incomplete record, it is an essay, do not take seriously.0. Find the kind of Linux stack as a pure software implementation, retaining the hardware interface, but this article doe

We have introduced some content about the WAP protocol stack in the above article. For details, refer to the application environment and main protocols of the WAP protocol stack. Next, based on the content of the above article, Let's explain other related knowledge in depth. Wireless Transaction

http://view.inews.qq.com/a/20161025A0766200QQ in narrowband eraQQ is a narrow band of the most representative of the product, in that network transmission efficiency is lower than the era, we still remember Google's homepage? Why is the simple page of Google so concise?Google was born in 1998, is also in the narrow-band era, you will find its home byte size is less than 1024, why less than 1024 bytes, because the Ethernet MTU (that is, the largest transmission unit) is 1024,google in order to le

In Android, the structure of the Bluetooth system is as follows:In this architecture, the bottom-up sequence is the module driver, the Bluetooth protocol stack, the bluetooth.apk, the framework, and various Bluetooth applications. Among them, the kernel of the driver is directly and hardware to deal with, generally by the module manufacturer. Android layer, the bottom is the processing of specific Bluetooth

We have already introduced and explained the basic content and design steps of the IPv6 protocol stack in detail in the previous article. Now let's test our module functions, check whether it can be used normally. For detailed development environment and test steps, refer to the following. Implementation and Test on Altera De2 Development Environment: AlteraDe2 hardware platform), QuartusII5.1 and NiosII5.1

The Xixiang program was finally completed. Since the kernel module was unable to be downloaded, I had to write it myself. After understanding the principle of the Xixiang program, writing this module is not very troublesome (in fact, it is not simply to write the module, but to directly modify the kernel protocol stack Code). let's first talk about the principle and then talk about the kernel modification s

For the tcp ip protocol stack, we have already talked a lot about its principles. However, the principle is not enough. In this regard, we will give you an actual operation example to explain, first, let's take a look at the TCP/IP protocol stack for single-chip microcomputer that runs on single-chip microcomputer. As

We have already learned about the SIP protocol, which we will always see in the Unified Communication Platform and VOIP business. So here we will give you a brief discussion on the development of the SIP protocol and the SIP protocol stack. 1. About the SIP protocol Currentl

The use of the IPv6 protocol stack has gradually been accepted by everyone. Now many friends are trying to use IPv6. How can we install the IPv6 protocol stack? Now let's take a look at the IPv6 protocol stack Installation Process

article focuses on the introduction of ELK. Back to top ELK protocol stack introduction and architecture ELK is not a software, but a complete set of solutions, is the first acronym for three software products, Elasticsearch,logstash and Kibana. These three software are open-source software, usually with the use, but also attributed to elastic.co company name, it is referred to as ELK

During our understanding of the SIP protocol stack, we found that the application of the SIP Protocol can be implemented on many platforms and devices. The following software is required for the establishment of the SIP Soft Phone development environment to develop a SIP-based soft phone on windows or linux platforms: Server Software: registers multiple clients t

Recently, I have been porting the network protocol stack. I have found a lot of information about the protocol stack. This is a summary of some professional terms and is hereby recorded for reference. 1. Several data exchange methods and features Line switching: the concept of the source telephone system. The hardware

This article is reproduced to: http://colobu.com/2014/09/18/linux-tcpip-tuning Recently busy with debug and tuning of system performance. Some performance bottlenecks and Linux TCP/IP protocol stack settings, so specifically Google the Linux TCP/IP stack of the parameters of the meaning and configuration, recorded.If you want to permanently save the settings for

1. How does the Redhatlinux system install the IPV6 protocol stack? (1) Modify the/etc/sysconfig/network file and add the following configuration text: Networking_ipv6=yes (2) Run command: Servicenetworkrestart (3) Use command ifconfig-a to view IPv6 address information 2. How do other Linux systems install the IPV6 protocol
