pgm multicast

Let's explore a different use of the multicast () operator in RxJS, where can provide a selector function as a sandbox The where the shared Observable is available.When we have the code like below: var result = Rx.Observable.interval (1000 ). Take (6 ). do (x = Console.log ( ' source + X"). Map (x => Math.random ()); var Delayedresult = result.delay (500 Span style= "color: #000000;" >); var merged = Result.merge (Delayedresult); Merged.su

Grouping multicast addresses Shows the space of the whole IP multicast address. Where: The 224.0.0.0 to 224.0.0.255 address range is reserved by IANA, and the address 224.0.0.0 is retained without allocation. Other addresses are used by routing protocols and topology search and maintenance protocols. The addresses in this range belong to the local category and will not be forwarded by the router regard

IP Multi-channel broadcast C #. NETHttp: // http://www.c-sharpcorner.com/introduction: Currently, multi-point broadcast is widely used. With the increasing bandwidth and multimedia Stream utilization, broadcast will become a widely used method in the near future. What is IP multicast? IP multicast is a broadband storage technology that can be used to solve information congestion on the network. Send a sing

Record a Multicast DNS (mdns) problem-(ifconfig in linux), mdnsifconfig Preface:Recently, the problem of mdns query has been fixed. The problem can be summarized into three parts, which are basic issues: 1. Gateway ifconfig query address 2. encoding of multiple programs occupying one port at the same time 3. mdns protocol and source code Mdns is a protocol used for LAN discovery. For the linux system mounted by the gateway, you must first determine

First, when the OSPF adjacency relationship is established, the DR and all devices are full,bdr with all devices for the full,drother between 2-way (DR and BDR are also full).When OSPF routes are updated, DR/BDR monitors 224.0.0.5 and 224.0.0.6.Drothe Monitor 224.0.0.5.When the Drother route has an update, DR/BDR will receive it, but the flooding is sent to all devices by DR.The following experiments all update to "new release route".Second, topology information650) this.width=650; "Src=" Http:/

Because broadcasts and multicast do not establish a connection, only the UDP protocol is used.Broadcasting is sending broadcast messages to all hosts in the LAN.? 1, the representation of the IPV4 address {Subnet ID, host ID}a/b/c/d/e class address, 1 means all fields with bit 12. Subnet broadcast address, {subnet Id,-1}, specify the broadcast address of all interfaces on the subnet 192.168.1.0/24 the broadcast address on the subnet 192.168.1.2553. Re

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

The role of network layer and Internet multicast 1. Briefly describe the role of the OSI physical layer, data link layer, and network layer? Network Layer: provides the most suitable path for packets or groups through the Communication Subnet through the routing selection protocol (Routing Algorithm). Data Link Layer: various control protocols are used to convert erroneous physical channels into error-free data frames that can be reliably transmitted.

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.

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
