Protocol buffers (Protobuf) format

Protocol buffers (protobuf) format to encode the security log. SRX Series Firewalls send the encoded security log to the target device. The logs are saved on the target and decoded for readability. The primary purpose of protobuf is to reduce the size of stream logs (compared to syslog and sdsyslog) and increase the events per second (EPS) ratings with the log server.
