    Using port 5228, 5229, and 5230 for Google Cloud Messaging - Android

    Google Cloud Messaging for Android (GCM) is a service provided by Google that would give an helping hand to the developers to send data from servers to their Android applications on Android devices, and upstream messages from the user's device back to the cloud.
    • There is flow of information towards the Android application to intimate that new data is to be fetched from the server.
    • This small message may contain notifications to let the application know that the data can be downloaded from the server. For example, an application may receive a notification that an email has been sent but to actually view the email, it has to be downloaded.
    • Sometimes, if the data is very small(4kb), it is carried to the application along with the notification. For example, instant messaging apps.
    • The GCM service handles all aspects of queuing of messages and delivery to the target Android application running on the target device.
    • The ports 5228,5229 and 5230 has to be opened and should be allowed in the firewall. Usually, port 5228 is used.
    • Port 5228 is used by the Google Playstore (Android market).
