  1. OpenSourceNetwork LibraryHalfNetwork 임영기 javawork93@gmail.com

  2. HalfNetwork란 • ACE를 이용하여 만든 C++ 네트워크 라이브러리 • Half-Sync / Half-Async(POSA2) 패턴의구현물

  3. ACE • Open source object-oriented framework • Socket / Thread / Lock / Buffer • 여러 패턴의 집약체 • Wrapper Façade • Adaptor • Composite

  4. ACE 컴파일 • $ACE_ROOT : ACE_wrappers폴더 • $ACE_ROOT/ace/config.h생성 • #define ACE_HAS_STANDARD_CPP_LIBRARY 1 • #define ACE_USES_WCHAR 1 • #include "ace/config-win32.h“ • $ACE_ROOT/ace/ace_Static.sln 컴파일 • aces.lib acesd.lib • ACE_AS_STATIC_LIBS 선언

  5. Half-Sync / Half-Async Pattern

  6. Message_Block의기능 #1 버퍼 관리 ReadPtr WritePtr Size Size = block.size(); // Size Length = block.length(); // WritePtr – ReadPtr Space = block.space(); // Size – WritePtr

  7. Block에서 읽어오기 memcpy(buffer, block->rd_ptr(), read_length); block->rd_ptr(read_length);

  8. Block에 쓰기 block->copy(buffer, write_length);

  9. Message_Block의 기능 #2Chained Message_Block Block Next • Composite 패턴 • Head만 넘기면 됨 • 데이터 복사를 줄여준다

  10. Queue에서 꺼냈을 때 Command Block Payload Block

  11. Command Block

  12. Payload Block

  13. 초기화 코드 NetworkFacade->Create(newProactorFactory); NetworkFacade->AddAcceptor( port, queue_id); NetworkFacade->Open();

  14. 패킷 처리 코드 ACE_Message_Block* commandBlock = NULL; NetworkFacade->PopMessage(queue_id, &commandBlock, -1); ... switch(postee.command) { caseMessageHeader::ESTABLISH: ... break; caseMessageHeader::READ: ... break; caseMessageHeader::CLOSE: ... break; }

  15. 기타 함수들 NetworkFacade->SetWorkerThreadCount(count); NetworkFacade->Connect(ip,port,queue_id); NetworkFacade->SendRequest(streamID,block); NetworkFacade->CloseStream(streamID); NetworkFacade->PopAllMessage(block); NetworkFacade->SuspendAcceptor(port); NetworkFacade->ResumeAcceptor(port);
