One disadvantage of broadcast is that it affects all computers in the subnet, even if they are not interested in this broadcast message. Multicast can solve this problem. Multicast adopts Promotion Technology(Browsing Web pages is a drawing technology, and also a pushing technology.EmailService). Multicast is also called
The following is reproduced from: http://www.enet.com.cn/article/2011/0705/A20110705880890.shtml I. Introduction to the topology structure of the networkThe structure of the network consists of three layers: the core layer, the aggregation layer and the access layer.The core layer consists of 5 core nodes (each core node is configured with a routing switch CiscoCatalyst6509), which is interconnected via gigabit fiber to an incomplete mesh structure.The aggregation layer consists of 53 nodes (one

. The subnets can be divided into four subnets (,). On average, each subnet is 2 ^ 6-2 = 62, because the first subnet requires 100 instances, the subnet is divided into one A subnet contains 100 hosts. Therefore, the binary system requires at least seven host numbers. Because the default subnet mask is 255.255.255.0, The subnet mask is 255.255.255.255.128 and the IP address is 192.168.15.1 ~ 192.168.15.127 A single subnet has 60 hosts. Therefore, the binary system requires at least six host numb
Technorati labels: CISCO, multicast, multicast, RPF, CCIE RPF, reverse path forwarding. It is an important foundation for multicast forwarding. Only after successful RPF detection can multicast traffic be correctly forwarded in the network. When you query the keyword "cisco rpf detection mechanism and working principle
IPv6 provides many high-quality service functions, especially the multicast technology, which changes the traditional transmission mode of data streams and overcomes the shortcomings of unicast and broadcast. Modern distance education can use these advanced functions to promote its own development. (1) feasibility of applying IPv6 Multicast technology to Modern Distance Education 1. The coverage rate of dis
MulticastUnlike the one-to-one transmission over the network, it is a one-to-many (at least one) point based on UDP/IP point transmission protocol, The multicast router uses the IGMP protocol to check whether the multicast group receiver exists in the network segment connected to each interface, that is, the group members. If a member exists, the multicast router
In the network overuse phase, we will use the dual-stack technology to connect the two networks. In the double stack technology, IPv6 multicast provides powerful functions. It can run on both the router and host, and can write v4 and v6 to form a convergence point. In transition technology, IPv6 multicast is very important. We will discuss this in depth. IPv6 multicast

Multimedia TrafficThere are three main modes of communication in the network: 1, Unicast (unicast) 2, broadcast (broadcast) 3, multicast (multica
IP multicast (also called multicast or multicast) technology allows one or more hosts (Multicast sources) to send a single packet to multiple hosts (once and simultaneously) TCP/IP network technology. Multicast, as a one-to-multiple-point communication, is one of the effec

Here's how to start our multicast programming: First, the concept of multicast Multicast, also known as "multicast", the network of the same business type of host logically grouped, the data sent and received only in the same group, other hosts did not join this group can not send and receive the corresponding data.
Recently, I was writing a Distributed Instant chat program. To enable normal communication between Intranet users, I want to use multicast to broadcast data" According to the query data, UDP broadcast can only be effective on the Intranet (the same network segment), while Multicast can better implement mass data across network segments. Introduction There are three transmission modes: unicast,

In other words, the client sends information to the server. The client only needs to give the Server IP address and port number, and then encapsulate the information in a message to be sent and send it out. The client does not care whether the server exists or whether it can

Disadvantages of broadcasting: routed isolation, non-cross-network segments, wasted traffic, and hardware resourcesOSPF Build neighbor: Unicast: Too troublesome broadcast: wasting resource multicast: IGPBenefits of Multicast:1, the concept of the group2, send data reasonable use of bandwidth resources, reduce the sender's CPU resource consumption3, do not know the address of the recipient4.

In a local area network, administrators often need to send a piece of information to a group of users. If the use of a one-to-one delivery method, although it is feasible, but too troublesome, there are often leakage, 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 I
Differences between Winwods NLB unicast and MulticastWindows NLB (network load balancing) is a load balancing technology that Microsoft has provided on Windows 2000 Server. NLB uses a distribution algorithm to distribute Server Load balancer across multiple hosts to improve IP-based key services (such as Web, virtual private network, streaming media, Terminal Services, and proxies) scalability and availability, while detecting host faults and automatically allocating traffic to other operating h
The MAC address is a 48-bit (6-byte hexadecimal number) Address used on the second layer of Ethernet to identify the device location. The MAC address is divided into two parts. The first 24 digits are the unique identifier of the organization (oui, organizationally unique identifier), and the last 24 digits are allocated by the vendor. MAC addresses can be unicast, multicast, or broadcast. The Unicast address indicates a single device or node,
