High Performance TCP/UDP/HTTP Communication Component

HP-Socket

High Performance Network Framework

Description

• Server Based on IOCP/EPOLL communication model, combined with technology of memory pool, private heap etc., efficient memory management is implemented to support large scale and high concurrent communication scenarios.
• Agent The Agent component is essentially a Multi-Client component that uses the same technical architecture as the Server component. An Agent component object can create and efficiently handle large-scale Socket connections at the same time.
• Client Based on Event-Select/POLL communication model, each component object creates a communication thread and manages a Socket connection. Client components are suitable for small-scale client scenarios.

Workflow

1. Create listener object
2. Create component object (and binding with listener object)
3. Start component object
4. Connect to dest host (for Agent Component only)
5. process network events (OnConnect/OnReceive/OnClose etc.)
6. Stop component object (optional: component object will be stopped before destroy in step 7)
7. Destroy component object
8. Destroy listener object

Example

• C++ Example

#include <hpsocket/HPSocket.h>

/* Listener Class */
class CListenerImpl : public CTcpPullServerListener
{

public:
	// 5. process network events
	virtual EnHandleResult OnPrepareListen(ITcpServer* pSender, SOCKET soListen);
	virtual EnHandleResult OnAccept(ITcpServer* pSender, CONNID dwConnID, UINT_PTR soClient);
	virtual EnHandleResult OnHandShake(ITcpServer* pSender, CONNID dwConnID);
	virtual EnHandleResult OnReceive(ITcpServer* pSender, CONNID dwConnID, int iLength);
	virtual EnHandleResult OnSend(ITcpServer* pSender, CONNID dwConnID, const BYTE* pData, int iLength);
	virtual EnHandleResult OnClose(ITcpServer* pSender, CONNID dwConnID, EnSocketOperation enOperation, int iErrorCode);
	virtual EnHandleResult OnShutdown(ITcpServer* pSender);
};

int main(int argc, char* const argv[])
{
	// 1. Create listener object
	CListenerImpl s_listener;
	// 2. Create component object (and binding with listener object)
	CTcpPullServerPtr s_pserver(&s_listener);
	
	// 3. Start component object
	if(!s_pserver->Start("0.0.0.0", 5555))
		exit(1);
	
	/* wait for exit */
	// ... ... 
	
	// 6. (optional) Stop component object
	s_pserver->Stop();

	return 0;
	
	// 7. Destroy component object automatically
	// 8. Destroy listener object automatically
}

• C Example

#include <hpsocket/HPSocket4C.h>

EnHandleResult __HP_CALL OnClose(HP_Agent pSender, HP_CONNID dwConnID, En_HP_SocketOperation enOperation, int iErrorCode);
EnHandleResult __HP_CALL OnShutdown(HP_Agent pSender);

int main(int argc, char* const argv[])

		exit(1);
	
	// 4. Connect to dest host
	::HP_Agent_Connect(s_agent, "remote.host.1", REMOTE_PORT_1, nullptr);
	::HP_Agent_Connect(s_agent, "remote.host.2", REMOTE_PORT_2, nullptr);

	/* wait for exit */
	// ... ... 
	
	// 6. (optional) Stop component object
	::HP_Agent_Stop(s_agent);

	// 7. Destroy component object

	// 8. Destroy listener object
