1. Introduction of unicast, multicast, broadcast 1.1. Unicast (unicast)Unicast is the transfer of data to a specific host. For example, send an IP packet to a host. At this time, the data link layer gives the data header inside is very specific destination address, for Ethernet, is the specific network card MAC address (not FF-FF-FF-FF-FF-FF, this is the broadcast address). Now the host with the routing function should be able to direct the unicast da

In previous articles, we have explained the content of the IPv6 protocol. We should remember that in IPv6, there are unicast IPv6 routing protocols and IPv6 multicast routing protocols. Now let's take a look at the latter. What content does the IPv6 Multicast Routing Protocol contain? Let's take a look at the following content. IPv6 Multicast Routing Protocol IPv

Broadcasting sends broadcast information to a node regardless of whether a node is in a specified group, this can easily

can be an IP datagram, or it can be a shard of an IP datagram.Broadcast and multicastThere are three types of IP addresses: unicast addresses, broadcast addresses, and multicast addresses.Broadcast and multicast are only applied to UDP, and they are important for applications that need to transmit messages to multiple receivers at the same time. TCP is a connection-oriented protocol that means that there i

WebRTC represents the best technology in the field of real-time communication since the date of birth. But for a long time, it supported the video encoder only VP8, and later with H265/VP9 as the representative of the birth of the next generation of video Encoders, WebRTC appeared VP9 Codec. The most widely used H264 has been kept out of sight. Until Cisco announces its H264 codec open source for OpenH264,

IANA has allocated the Class D address space to the IP multicast address. the address of the Class D space is located in the first four digits of the first byte and identified by the binary value 1110. therefore, the multicast address range is: 224.0.0.0 to 239.20.00000000d Class address: www.2cto.com byte 1 byte 2 byte 3 byte 41110 xxxx xxxxxxxxThe principle is as follows: the address of the space is expre

. 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.

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

For project reasons, audio and video is required, so the open source WebRTC (with BDS open source agreement) and Google supported open source project are selected.

"WebRTC, a name derived from the abbreviation of Web real-time communication (Web real-time communication), is a technology that supports web browsers for real-time voice conversations or video conversations, and is Google's $68.2 million acquisition of Global in 2010 IP Solutions A technology that Google has made available to the company. ”

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
