dynamic and flexible. The initial IGMP specification was defined in RFC 1112 in detail. We generally refer to this specification as "IGMP version 1", written by S. Deering of Stanford University in August 1989. Later, W. Fenner of Xerox PARC significantly updated the earliest IGMP version 1. The updated result is RFC 2236 file, that is, IGMP version 2. Two versions of IGMP can perform a few operations on each other. IGMP version 2 is nearing official

frame is finally sent to the destination host through the L2 switching network. Vrouters do not forward Ethernet broadcast frames, so the Routers configured between VLANs do not change the isolated broadcast achieved by Vlan division. VLAN frame format * Ethernet V2 MAC frame format Two Ethernet MAC frame formats are available: DIX (DEC, Intel, Xerox) Ethernet V2 standard (RFC894) and IEEE 802.3 standard. Figure 6 shows the common MAC frame format of

detect conflicts at any time. In the event of a conflict, the transmission should be stopped to avoid wasted media bandwidth due to invalid frames transmitted. Then, after a random delay for a period of time, resend the media and resend the frame.At first, three companies, Inter, Xerox and DEC, proposed the Ethernet standard. Later, the IEEE organization formulated the 802.3 standard, which stipulated the MAC Sub-layer of the Ethernet physical layer

Structured programming can be applied to almost any programming language, while object-oriented programming requires language support [1], which also hinders the development of object-oriented technology. In fact, in the late 60, the language that supported object-oriented features was only Simula-67. By the 70 's, Alan key,

understand software systems from a higher abstract concept. AOP may provide a valuable tool. This can be said: Because the AOP structure is used, the source code of JBoss 4.0 is much easier to understand than JBoss 3.x, which is very important for a large complex system. From another aspect, it seems that not all people need to care about AOP. It may be an architectural design option. If you choose a J2EE system, the above general aspects of AOP have been implemented by J2EE containers. J2EE

ArticleDirectory What does "ibatis" mean? How do you pronounce ibatis? What does "ibatis" mean? Today, the word "ibatis" is synonymous with the SQL maps and the DaO frameworks -- much like "Xerox" is synonymous with "photocopy". But there is a meaning to the name. Recall that ibatis has roots in cryptography software. ibatis was actually named by combining two words: "Internet" and "abatis". reference.com defines abatis this way:

here want to the 3 models to sum up small respectively. Let's go back to the MVC architecture model. I have been working in the past few years the first contact is MVC (then there are no two models, haha), then give me the most intuitive feeling is the M and V of the Implementation code separation, so that a program can have different presentation forms; C is used to connect M and V. In fact, in MVC (Model View controler), m--refers to the data model, the v--view, the user interface, the c--co

In 1968, he became a professor of informatics at the Zurich Federal Institute of Technology and studied at the Xerox Palo Alto Research Center for two years. He is the main designer of several programming languages, including algol w, modula, Pascal, Modula-2, Oberon and so on. He is also one of the inventors of Euler's language.
