Network device and method for dynamically allocating connection resources

A network device for dynamically allocating connection resources for a plurality of clients, the network device comprising:

• at least one processor;
• memory;
• one or more programs that are stored in the memory and are executed by the at least one processor, the one or more programs comprising:
• a receiving module operable to receive a new connection request from one of the plurality of clients;
• a resource determining module operable to determine whether all connection resources of the network device are unavailable, and further determine whether a difference between connection resources occupied by the one client and a connection resource hog client is less than a determined threshold upon the condition that all connection resources of the network device are unavailable, wherein the connection resource hog client is another one of the plurality of clients which occupies most connection resources of the network device;
• a priority determining module operable to determine whether a first connection resource with a predefined priority is found in the connection resources occupied by the one client upon the condition that the difference is less than the determined threshold;
• a releasing module operable to release the first connection resource with the predefined priority that is found in the connection resources occupied by the one client;
• and
• an allocating module operable to allocate the released connection resource to the one client according to the new connection request.
