mdns

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

DNS and mDNS name (name) compression rules1. Rationality of name compression: When transmitting data over the network, if the data size is too large, it will take a long time for the Network to send, so that the network efficiency is relatively low. To improve network efficiency, you can reduce the size of data sent. When an mDNS packet is generated, the mDNS exe

frameworks and standards: first, DLNA classifies virtually all electronic products on the market (figure 30), allowing DLNA to standardize on a wide range of devices, On the other hand, DLNA is the basis for the standard of interaction between different devices.Figure a DLNA-defined device category and typeNext, DLNA defines the device's working architecture (Figure 31), where UPnP is an important protocol layer for device discovery, connectivity, and control (reference articles), while media d

the Region network segment, and then checks whether the address conflicts locally, if there is a conflict, another new IP address is randomly generated until the available IP address is found.2.2 name resolutionIn traditional network environments, the correspondence between names and IP addresses is resolved through DNS. When a device needs to access a domain name, such as "www.saup.com", the device sends "www.saup.com" to the DNS server, and the server returns the IP address corresponding to t

new IP address until the available IP address is found.2.2 Name AnalysisIn the traditional network environment, the correspondence between the name and IP address is resolved through the DNS service. When a device needs to access a domain name, such as "www.saup.com", the device sends "www.saup.com" to the DNS server,The server returns the IP address of the domain name, and the device then accesses the destination server using the returned IP address. In a network environment without a hub serv

. Politics provides modules that allow us to build a self-repairing worker class that can is run on all our instances. But it designates only one instance at a time-to-do the work specified for a given time period. Politics calls this worker a token worker. Under the covers politics uses three different technologies to maintain order in all the worker classes. One of them we already KNOW-DRB. The other technologies it uses is Memcached and MDNS (a
