allow incoming echo requests. IGMP Protocol (Internet Group Management ProtocolInternet Group Management Protocol). This protocol runs between the host and the multicast router directly connected to the host. It is a protocol used by the IP host to report the identities of multicast Group members. Through the IGMP protocol, on the one hand, you can use the IGMP protocol host to notify the local router to join and receive information about a specific multicast group. On the other hand, the route

frame is discarded when the target station receives a data frame with an error and does nothing else. the correction of errors is determined by the top management. if some data is lost and retransmitted at the higher level, Ethernet does not know that this is a re-transmitted frame, but is sent as a new data frame.

The RIP Protocol is a type of routing protocol. It has been applied in many places. For the network architecture, the routing information protocol (RIP) is an internal mechanism in our network, mainly for managing network management and routing. The RIP Protocol is also required for data distribution and transmission between different protocols. Now we have come to understand every aspect of this agreement in detail. I. background The route information protocol (RIP) uses the number of hops as t

Next we will parse the content of the route information protocol RIP. For some of the content of this protocol, we will mainly explain the background of this Protocol, as well as the contents related to the route update metric, stability, and timer. I hope this will help you. I. background The route information protocol (RIP) uses the number of hops as the distance vector protocol of metric. RIP is widely used in global Internet routing. It is an internal gateway protocol that implements routing

The SPX Protocol is based on Xerox SPPSequences Packet Protocol, it is also a network protocol for LAN developed by Novell. In the LAN, the SPX protocol is mainly responsible for error-free processing of the entire transmitted data, that is, error correction. Application: the SPX protocol is generally u

the value used to select a path when the router forwards the route to the next vro in the forward packet to the next vro in the network. The common distance vector routing selection protocols include: Route Selection Information Protocol (RIP) is a distance vector routing protocol first implemented in Xerox Network System (XNS) and then implemented in Novell's NetWare) is the distance vector routing protocol developed by Cisco. The route selection ta

different representations. For example, a batch of statistical data can be represented by histogram, pie chart. C exists to ensure the synchronization of M and V, and once M is changed, V should be updated synchronously.[1-2]Model-View-Controller (MVC) is a software design pattern invented by Xerox PARC in the the 1980s for programming language Smalltalk-80, which has been widely used. It was later recommended as a design model for Oracle's Sun Compa

M is the exponential data model, V is the user interface, and C is the controller. The purpose of using MVC is to separate the implementation code of M and V, so that the same program can use different expressions. For example, you can use a column chart or pie chart to represent a batch of statistical data. The purpose of C is to ensure synchronization between M and V. Once M changes, V should be updated synchronously. Model-View-controller MVC) is a software design model invented by

concept that does not set the implementation of a specific language. It can overcome the disadvantages of a single inheritance feature language (such as Java). Currently, the specific implementation of AOP has the following items: AspectJ (TM): it was created in Xerox PARC. It has a history of nearly ten years and has mature technology. Disadvantages: Too complicated; destroys encapsulation; Special Java compiler is required. Dynamic AOP: Uses JDK

First, the origin of AOP technologyThe birth of AOP technology was not too late, as early as 1990, researchers from Xerox Palo Alto research Lab (ie Parc) analyzed the limitations of object-oriented thinking. They have developed a new idea of programming that might help developers improve productivity by reducing code duplication modules. With the gradual deepening of research, AOP has gradually developed into a complete set of program design ideas, t

What is MVC?I remember the first interview with phper (php is another web development language that can be quickly used for me). People asked me about MVC. I only know that m is model and v is view, c is the Controller. I know nothing about other things. As a result, I was asked questions !! I know how bad I am. So I decided not to give up on it!

I. backgroundThe route information protocol (RIP) uses the number of hops as the distance vector protocol of metric. RIP is widely used in global Internet routing. It is an internal gateway protocol that implements routing functions within the autonomous system. External gateway protocol (such as edge gateway protocol BGP) is used for routing between different Autonomous Systems. The predecessor of RIP is the Xerox protocol GWINFO. Later versions of r

thought about his wife's name Gloria before Pearl. However, there is already a language called Pearl, so the Pearl "a" is removed. It is worth mentioning that this name has always been lowercase, and the Unix file system is case-sensitive, and when Perl 4 was released in 1991, Larry Wall changed the initial letter to uppercase.LuaIn 1993, developed by Tecgraf, is a scripting language. The language was developed by Del and Sol, combining the advantages of both, and adding functions such as flow

an increasingly complex task.L-less Less is the first Ruby gem to have CSS with dynamic language features, including variables, operators, and nested rules. The real effect of less is to convert CSS using advanced features into standard CSS. These are done via HTTP handler when the Web client initiates the request. It can also be done at the time of editing. In addition, less can be configured to automatically minimize the generated CSS files, not only saving bandwidth, but also making the end

The topological structure of LAN The main features of LAN are: The network is owned by a unit, and the geographical range and the number of sites are limited. LAN has broadcast function, from a site can easily access the entire network, the host on the local area network can share a variety of hardware and software resources connected to the LAN. The local area network can be divided into bus structure, ring type structure, star structure, net structure, tree structure and mixed structure
