The test code for multicasting is as follows:#include The following error occurred during the Ubuntu compilation run:The answers to the relevant information are as follows:It means that the tool was trying to use multicast and the network interface doesn ' t support it there be, likely causes :· Your machine doesn ' t has multicast support enabled. For example, on Linux and FreeBSD it's possible to compile

to a unique destination. In a conflict domain, all hosts can receive a unicast frame sent by the source host, but other hosts will discard the received frame when the destination address does not match the local MAC address, and only the true destination host will receive and process the received frame.BroadcastingThe second type of transmission is broadcast, which indicates that frames are sent from a single source to all hosts on a shared Ethernet network. The destination MAC address of the b

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

The Bluetooth mouse we purchased last week has been back. fortunately, it was the first time I used a wireless mouse. It was good to feel that there was no tail restriction and it was very convenient. There are two aspects to my worries. On the one hand, there are still limitations in buying such a thing online, I have never touched it myself, but I am very enthusiastic about the seller. I also took a picture on the spot to show it to me, but the mous

method One: 1. We directly in the computer desktop State in accordance with the "WIN" + "C" on the keyboard to open the windows8.1 system's Super button. 2. Then we go to the Super button and find "settings" as shown in the figure. 3. Then in the go to the Super button we find "Change computer settings" Click to enter, as shown in the following figure. 4. Then we find "Computer settings" below the "computer and equipment" shown in the following image. 5. Now we will see a "

1. The following figure shows our notebook Bluetooth is normally open, if not open their own first open, and then we right-click the Bluetooth icon, click on the pop-up menu "add Device" specific as shown below. 2. Then in the pop-up to add Bluetooth interface we click on their own to add Bluetooth 3. The system

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

First, from the Start menu, go to Control Panel, and click "Add Device" in the "category" view. Second, adjust the Bluetooth device (for example, the phone here) to be searchable. Third, after the computer search the Bluetooth device, click "Next". The fourth step, appears the authentication code prompt, chooses "is", then clicks "Next", clicks on the handset to agree to match, then waits for

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 offline state we use Bluetooth is still normal, the connection is normal. After we connected the device successfully we scanned the device and then clicked add it can be seen in the Bluetooth management as shown in the picture: If the drive appears normal our Bluetooth device can be used, if the connection is successful without using our

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

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
