Google Cloud Messaging now supports persistent connections, upstream messaging, and notification sync
At Google I/O 2013 on Wednesday, Google announced its Cloud Messaging (GCM) service is now part of Google Play Services, and has gained three new features as part of a major upgrade: persistent connections, upstream messaging, and notification synchronization. The new GCM features will be rolling out progressively, and developers can sign up today.
Persistent connections means developers can serve a large number of messages to many devices very quickly. Upstream messaging means developers can now send data in the other direction: from their apps to their servers. Last but not least, Google launched a new GCM API synchronizes notifications for developers.
Google also revealed it is now delivering 200,000 GCM push messages every second, or 17 billion messages per day. Furthermore, the average latency is now 60ms, which is about 30 percent faster than when it launched a year ago.
