ABSTRACT:
The claimed subject matter relates to an architecture that can provide substantially lossless compression and subsequent decompression of messages at an application level. In particular, the architecture, in one aspect thereof, can receive a set of messages. When application data for received messages does not match stored message, the message can be stored to a buffer. In contrast, if application data matches that for a stored message, the received message can be discarded and a message count incremented. The compressed message pattern can include the stored message and the message count. Upon decompression, the number of messages received can be identified by the message count and the application data can be readily recreated for all messages by copying that data. Non-application data, such as time stamp information can be reconstructed based upon a buffer period, other timing offset data, or other data fields included in the message pattern.
