multicast paging

Windows NLB (Network Load Balancing) is a load balancing technology that Windows $ Server begins to provide on the operating system. NLB uses a distribution algorithm to distribute load balancing across multiple hosts, increasing the scalability and availability of key IP-based services such as the WEB, virtual private networks, streaming media, Terminal Services, proxies, and so on, while detecting host failures and automatically reallocating traffic to other operations masters. Thus providing

Inside the Ethernet there will be broadcast and multicast. Both of these packages are an STA contracted to multiple Sta.Broadcast and multicast between LAN ports are reliably forwarded when there is no wifi, but it is not the same if WiFi is present.Power considerationsAccording to the Protocol, broadcast and multicast are sent to STA at Dtim. The Dtim in the AP

A python script that can send multicast data on LINUX. In fact, it is not too difficult to compile. The specific code is as follows: first declare that this is not what I wrote, but what I found, but what others wrote is quite good.

streaming media content, it is difficult to achieve two-way interaction because of the slow network transmission rate, so the effect is not satisfactory. This has largely weakened the attractiveness of online education to many learners, and thus greatly reduced the quality and effectiveness of distance education. The emergence of IPv6 not only solves the problem that 1Pv4 address space is almost exhausted, but also improves the basic Header Format of IP data packets. The most important thing is

This article describes in detail the implementation of the Sparse Mode of multicast routing, mainly from the discovery of RP, the establishment process of the shared tree and source registration, the conversion from the shared tree to the source tree is described in detail. I. RP discovery RP discovery mechanism: Several routers are configured as alternative RP, and the alternative RP sends an interface containing its own campaign, which is generally

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, and has the most promising future. I. unicast: Between Hosts "One-to-one"In the communication mode, vswitches and vrouters in the network only forward data without copying. If 10 clients need the same data, th

To do useful work, P2P applications must be able to discover and interact with each other. This article provides an implementation of IP multicast-based discovery.Before a software entity can participate in direct peer-to-peer interaction with P2P applications, the entity must discover the appropriate peer-to-peer points to interact. All feasible P2P architectures provide a solution for problem discovery. In this article, I will describe the implement

Turn from: http://run.bloghome.cn/posts/99860.html There are three kinds of communication modes in the current network: unicast, broadcast, multicast, in which the multicast time is the most late, but also has the advantages of unicast and broadcast, the most promising development. 1. Unicast: A one-to-one communication mode between hosts, where switches and routers on the network only forward and not rep

Concepts of unicast, multicast, broadcast, and anycast UnicastIt refers to the unicast method in which the destination address is a single objective in the computing machine's website. It is the most widely used network today. Generally, most of the network recommendations or services used use unicast Protocol, for example, all TCP-based protocol. [Unicast features] Each time only two instances communicate with each other, the sender and accept

All Hosts receive the report (the host sends a report every 10 seconds) 3. If the router receives the report, add the IGMP group ing table and forward traffic from the corresponding interface 4. the router sends a generral query every 60 seconds and sends it to all hosts to check whether there are any hos
