10. A game grammar-based packet capture and analysis method, comprising: capturing packets of game data transmitted and received between a game client and a game server; analyzing the captured packets to generate a game grammar based on analyzed results; and generating packets in compliance with the game grammar to apply the packets to the game server as a load, wherein the generating a game grammar includes: defining packet generation rules by analyzing an entire structure of the packets; grouping a series of packets into a group to define the group as an action of a game; defining protocols of communication between the game client and the server by analyzing the packets; generating the game grammar using the packet generation rules, actions and the protocols.
