methods, which are called multicast delegates.If you call a multicast delegate, you can call multiple methods sequentially consecutively. For this reason, the signature of the delegate must return void (otherwise, where should the return value be sent?). (When a delegate contains only one method, the declaration of its return type can refer to the encapsulated method, not necessarily void). In fact, if the

From "Baidu Knows", I don't know! There are three communication modes in the current network: unicast, broadcast, and multicast. Among them, multicast occurs at the latest time, but it also has the advantages of unicast and broadcast, it has the most promising future. I. unicast: One-to-one communication mode between hosts. vswitches and routers in the network only forward data and do not copy the

What is multicast?网络中存在3中传播形式，单播，广播，多播。 1. 单播 : 就是1->1 2. 广播 : 1->多(广播域内) 3. 多播 : 1->组(一组ip) 1 2 3 4 5 1 2 3 4 5 Relies on IP protocol implementations首先我们抛出一个问题，要是要你自己在网络中实现这种机制，你会怎么实现呢。哈哈，我的设计大概会是这样。设计思路 : 因为网络是通过ip协议来通信的，那我自然想到是否可以通过某一类标记来标志这种形式就是多播呢，答案肯定是可以的，其实别人也是这样实现的。下面看一张图。 1 2 3 1 2 3 D类IP地址（224.0.0.0到239.255.255.255）标记为多播地址。是吧，别人也这样实现啦。下面

tunnel through the communication between the AS and other. To distinguish between BGP running between AS and BGP running inside as, the former is called external BGP (ebgp), and the latter is called internal external BGP (ibgp ). The multicast routing protocol is used to maintain the connection between routers that form a multicast tree. Common multicast routi

solution will not be guaranteed. Solution 2: wired The cable solution can only deploy single-mode optical fiber cables at a distance of 12 kilometers, which is more time-consuming and costly. You can say you don't have to think about it. Solution 3: Internet + VPN The Internet can be said to be a public wide area network, and many telecom operators have established a four-way and eight-way long-distance network, which makes it possible for our compan

Distribution among peers. it's very cost valid tive as the stream is distributed among peers. you can either distribute stream from a client or FMS (with the future release ). Native IP MulticastThis one is distributed over the network not using P2P connection, but using network routing capabilities. it mostly works in internal, enterprise, VPN or LAN networks-basically in closed networks, which supports that. you can combine native IP

Abstract: multicast communication is a hot network technology. This article describes the basic concepts of IP multicast technology, multicast addressing, Internet Group Management Protocol (IGMP), multicast routing algorithms, and existing multicast routing protocols, and t

I. Introduction With the development of the network, people have developed various services on the network platform, such as E-mail, TELNET, FTP, and WWW. These services are point-to-point data transmission; people prefer to hold video conferences, listen to live concerts, and watch live broadcasts on the Internet. These are data transmission from point to point or to point, and IP multicast is required) communication technology. At present, this tech

In a local area network, administrators often need to send a piece of information to a group of users. If you use a one-to send method, although it is feasible, but too cumbersome, there will often be missed, wrong hair. In order to solve this group communication problem more effectively, a kind of multicast technology (also commonly called multicast communication) is presented, which is based on the IP lay

Original: http://blog.chinaunix.net/uid-28458801-id-5085099.html 11.3 Multicast Unicast is used for end-to-end communication between two hosts, and broadcasts are used for data communication on all hosts on the entire LAN for a host. Unicast and broadcast are two extremes, either to communicate with a host, or to communicate with hosts on the entire LAN. In practice, it is often necessary to communicate with a specific set of hosts, rather than all

Class d ip addresses (224.0.0.0 to 239.255.255.255) do not recognize a single interface on the Internet, but recognize an interface group, which is called multicast groups. Members of a single network use the IGMP protocol to communicate with each other. Multicast Routing Protocol for multicast routers, such as dvmrp (Distance Vector

Part of this article is reproduced in: http://network.51cto.com/art/200912/168407.htm Before talking about IGMP, it is said that IGMP packets cannot be transmitted outside the LAN (for details, see: http://blog.csdn.net/todd911/article/details/9530633), so how to communicate between routers after hosts in different network segments join multicast groups, do you know which subnet to forward? This is the function of the IP

assurance mechanism different from traditional unicast and broadcast mechanisms. IP multicast technology is the key technology to solve these problems.I. Overview of basic knowledge of IP multicast technology1. Concepts of IP multicast technologyIP multicast is also called multi-site broadcast or

Analysis of Three TCP/IP transmission modes (unicast, broadcast, and Multicast)The Multicast Technology of TCP/IP transmission mode is a type of TCP/IP transmission mode. Before discussing Multicast technology, let's take a look at TCP/IP transmission methods. There are three TCP/IP transmission modes: unicast, broadcast, and
