Abstract:

Application gateway is a key subsystem of the ASAS. It receives client requests and relays data between clients and back-end servers according to the control commands from the back-end servers. To provide high performance under heavy load, we design and implement it in the Linux kernel based on the mu  lti-thread event-driven framework and the protocol state machine. It has great flexibility in supporting many cluster services such as HTTP. Tests also  prove its high performance in data throughput and connection throughput.

Key words: cluster, application gateway, event-driven, protocol state machine
