This naturally requires a certain amount of overhead and is slower.* Unreliable mode: There is no guarantee that message transmission will be successful, nor is it guaranteed to arrive sequentially. It eliminates those costs, and it's faster.The efficiency of these two modes is similar in the case of no packet loss. However, in reliable mode, packet loss will cause all subsequent packets to be blocked, and the lost packets will be re-transmitted until they ar

/pubnubcoThose products of the real-time communications platform as a service (Realtime Platform-as-a-service), such as pusher or PubNub, typically use their own proprietary protocols. Pusher has disclosed detailed specifications [12] that they developed based on the JSON protocol, and encourages third parties or communities to help build clients in different languages. Although Pubnub are more closed, they

RedisEventPusher will be injected when an EventPusher implementation is required for a class. now we can type the EventPusher interface in the constructor or any other places where dependencies are injected through the service container: Use App \ Contracts \ EventPusher;/*** create a new class instance ** @ param EventPusher $ pusher * @ return void */public function _ construct (EventPusher $ pusher) {$ this-> pusher = $ pusher ;}Context binding Sometimes we may have two classes using the sa

actively to the server to obtain the latest data, This is the complete implementation of the push service. The XMPP protocol is relatively simple and deserves further study.But after a period of testing, I found that there are some deficiencies in ANDROIDPN:1. For example, when the time is too long, you can no longer receive push messages.2. The performance is not stable enough.3. If the message is pushed out of the server, it is no longer managed, regardless of whether the message successfully

that thousands of concurrent changefeeds can run in parallel, all getting results within milliseconds lat Ency.Comparing with realtime Sync Services like Firebase, PubNub and pusher, RETHINKDB offers better querying capabilities and Can push changes on queries and not just single documents. Also, RETHINKDB is a open-source system both at the protocol and implementation level. Finally, Rethinkdb ' s realtime push capabilities is architected for backen

This is a rather interesting space experience, and here is a tutorial written by Nermic Sehic in Cityos.io that lets you use Ibeancons.You can learn something about Bluetooth LE (Low power bluetooth®) and use the Swift programming language to write an application to detect all iBeacons (hardware) within the device range.Get this tutorial in Cityos.io-swift-tutorial-with-ibeacons-beginners-guide8.

The foreign parse, pubnub do very good, the basic version is also free, but because we all understand the reasons for foreign services in the domestic often cannot visit.Domestic do good have a push, Sina Weibo Android push also they do, concurrency reached 5000tps (can handle 5,000 transactions per se

timeliness. The two methods have such defects. Is there any better implementation method? Indeed, Android competitors, apple, have already achieved this-persistent connection. The apple push notification service provides a persistent connection between an Apple mobile terminal and a server. Through this channel, the server can locate a mobile terminal in real time, naturally, messages can be pushed. Similarly, the push mechanism similar to Apple apns can be implemented on Android systems. Cur
