China's communication access industry is developing very rapidly. Many people may not understand the problems and opportunities encountered in the development of the communication access industry. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. What is our overall target architecture? In our opinion, this is ITU, this is our layered architecture, and we feel that our view of the future network is on the Busin

image is increased by 0x20000, and the string is of course (now it should be 0x604002 ). So the pointer to the string is wrong. delta should be added to the pointer value. To enable the Windows loader to make such adjustments, the executable file contains many base-relocation item items for those locations that store pointers (in this example, 0x2134. The loader must add delta to each address. In this example, the loader should add 0x20000 to the ori

Now many companies use squid as the cache, and Alibaba is no exception. This is no secret. Squid's Coss file system is especially suitable for the cache of small files. It is the main means for many companies to store small image cache. Turn to the computer today and find a technical analysis written in the early stage for your reference. You are welcome to criticize and correct it. Squid Coss Technical Analysis1. Coss Mechanism Analysis1.1. Coss file structure analysis1.2. Coss Configuration An

the addresses of programs and data that are compiled to run in virtual memory to the actual physical addresses where the programs are stored in physical main memory. this translation process allows programs to run with the same virtual addresses while beingHeld in different locations in physical memory. -- MMU is used as a converter. The program can run in the same virtual memory, and each program is stored in different physical memory. We begin with a review of the protection features of an MP

raise jumps out. (Sharing and protection) Of course, it is not enough for a large land. To make more money, landlords rent out all the land, he tried to dig out the Dongdong land in a field that some farmers had not planted for the time being and put it in the warehouse first. This is enough, but the landlord said, this is "virtual storage ".) Do you mean this landlord is good or bad ?? Overview: This chapter discusses the management of the primary storage space. The primary bucket is divided i

Abstract: This article mainly introduces several file merging, address determination, symbolic parsing and relocation related problems in static links, taking the GCC compiler as an example.first, when the linker links multiple files, how do you combine them into one file? Mode one, superimposed by order, that is, multiple files are superimposed in sequence, mode two, similar segments are merged. The way to go depends on which way the benefits outweig

usage, scalability, and portability of executable files are closely related to the definition of file formats and file loading processes. Studying the formats of executable files is very meaningful for writing high-performance programs and using hacker technologies. Regardless of the executable file format, some basic elements are required. Obviously, the file should contain code and data. Because the file may reference the symbols (variables and functions) defined by the external file, the

), Expires (not recommended because it specifies the absolute expiration date rather than the relative number of seconds), Etag and Last_Modified. Etag corresponds to If_None_Match (abbreviated as INM) in the request header, and Last_Modified corresponds to If_Modified_Since (abbreviated as IMS ). the new HTML5 application cache supports offline document storage, which makes offline document data effective and reduces traffic and is used more on mobil

depending on the needs of customers. Because the user of the private net mostly concentrates in the province, therefore proposes the provincial GGSN and the private network direct interconnection, may reduce the route circuitous. For VPN services already on the Web, you can continue to use the original authentication and address allocation method, RADIUS server and DHCP server placed on the enterprise side, the corresponding GGSN need to support the DHCP relay and Radius client features For pri

We all know squid will automatically cache static files, but for this dynamic Web page How to let it also cache it, so look for it on Google, find the above mentioned the cache of Google Earth blog article.

PTT is also known as "one-link", which is characterized by a short call set up time, to occupy the channel when talking, only listening to listen to the channel, the receiver does not need to pick the machine at any time to listen to the downlink call information. The PTT business based on public cellular mobile communication Network is called POC business. The future mature POC business is based on the 3G network, it fully utilizes the characteristics of the 3G Mobile packet Network, based on t

For personal understanding about the static link of C language, please refer to the correction and static correction. Abstract: This article mainly introduces the problems related to file merging, address determination, symbol parsing and relocation in static links. The GCC compiler is used as an example.First, when the linker links multiple files, how does one merge them into one file? Method 1: add multiple files in sequence. Method 2: Merge similar

Dynamic links do have a number of advantages, much more flexible than static links, but at the expense of a portion of performance. According to statistics elf program in static link than dynamic library slightly faster, about 1%-%5, of course, this depends on the characteristics of the program itself and the operating environment. We know that the main reason that dynamic links are slower than static links is that the dynamic link has a complex got location for both global and static data acces

combination of the above two methods: the use of C + + coding, to achieve complete concealment. Moreover, the author's method greatly simplifies the writing of the remote thread code, which makes it difficult to write and the common procedure is basically consistent. Basic knowledge It is really a good idea to have your code as the thread of the hosting process and execute it in the address space of the hosting process. But to put the program to work in the address space of other processes, y

rapidly cultivated a large number of user groups. This phenomenon provides a lot of meaningful inspiration for fixed network operators and mobile network operators: IP-based multimedia applications will be the core competitiveness for users and increase the ARPU value. In addition, compared with the traditional TDM signaling service implementation method, the IP-based service implementation method is convenient, flexible, and fast. Therefore, fixed network operators and mobile network operators

People often get confused when they understand the IPv6 in the 3GPP/3GPP2 system, which is caused by the IPv6 at two different levels. First is the data load level, where the user data flow through the operator PLMN from MS to PDN. The other is the transport load level, which is two different logical levels from the data load level. Generally speaking, IPV6 will appear in the four areas of the 3GPP/3GPP2 standard. 2 at the user data load level, 2 at the transport load level. One thing needs to

avoid the use of relocatable loading mode. Mount the module into the appropriate location in memory, depending on the current memory situation. The process of modifying the instructions and data in the target program is called relocation, and the address transformation is usually done once at the time of loading, so it is also called static relocation, as shown in Figure 3-2 (a).
