multicast vpn

For a 2.6 kernel, there is a struct pointer inside the Net_device,struct dev_mc_list *dev->mc_listBy accessing it, you can loop through all of the multicast MAC addresses.However, the new kernel (at least 3.10) has changed, insteadstruct netdev_hw_addr_list mc;We can obtain the corresponding data by directly accessing the MC, or we can take advantage of the macros provided by the Linux kernel.netdev_mc_count(dev)This macro can get the current total nu

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

Dizzy, the article just sent is gone, and csdn is too frustrating. It's hard to write an article and submit it without responding.Recently, I was testing the sep4020 network. Because many Nic drivers that have been porting 4020 are not very familiar with the multicast part, but it was also directly transplanted like someone else's driver. Recently I wanted to test whether 4020 of multicast is supported. So

9. multicast forwarding-Multicast Routing Protocol The unicast routing protocol looks at the destination address of the package. The Multicast Routing Protocol depends on where the package comes from. It blocks the loop through RPF reverse route forwarding. RPF is used to determine whether the packet is received by the interface closest to the source --- use t

The Traditional VPN technology is no longer competent for the mobile Internet, vpn mobile InternetWith the rapid increase of network bandwidth and the gradual reduction of access fees, more and more videos will be transmitted on the Internet instead of text. The video performance is direct, while the text is abstract, video Production is convenient and fast, while text is complex and slow. You can use a cam

In general, VPN users are connected to the VPN server is to enter the password, if so, in some public places when the password is likely to cause leakage of passwords, resulting in unnecessary losses. Password Authentication protocol Although the hardware requirements are not as high as the Challenge Handshake protocol, however, in terms of security, it is still a distance from the challenge handshake agree

"TCP/IP Detailed Volume 1: Protocol" 12th chapter broadcast and multicast---reading notes1. IntroductionBroadcast and multicast are used only for UDP, and they are important for applications that need to transmit messages to multiple recipients simultaneously.Sometimes, a host sends frames to all other hosts on the web, which is the broadcast.Multicast (multicast

A unicast address identifies a single IP interface, and the broadcast address identifies all IP interfaces for a subnet. Multicast addresses represent a set of IP interfaces, unicast and broadcast are the two extremes (either single or full) of the addressing scheme, and multicast is intended to provide a compromise between the two. Multicast is an important tool

Teamviewer vpn + win7 vpn create a remote access to the Intranet environment1. teamviewer vpn is the simplest. Select vpn as follows. However, you must select this feature when installing teamviewer.Connect and remember the partner ip address.2. Set up an "incoming connection" for the Intranet PC in win7

In this case, network radio may need to transmit the same data to tens of thousands of users at the same time, which is certainly unreasonable if it is transmitted once per user in the form of transmission we have previously spoken. Therefore, multicast technology is introduced to solve this problem, it can send the same data to a large number of users at the same time. The basic principle is this: there is a mult
