Study And Implementation On The Collaboration Platform Of Logging Interpretation Based On P2P And VNC

At present, data processing and interpretation of integrated software (LEAD software), has been development successfully by China Petroleum Logging Co.Ltd. LEAD software was promoted by many famous companies, such as Qinghai oilfield institute, institute of huabei oilfield, jidong oilfield institute, Great Wall drilling engineering company.LEAD software has become mainstream software of PetroChina, because of its the advanced technology, high efficiency, strong market competitiveness. LAED Software can locally run, but not remotely. The logging interpretation experts who are not in local can't get the LAED software logging data across the Internet, so they can't help local userse analyzing logging data。For LEAD software application requirements, we research the collaboration platform of logging interpretation based on P2P and VNC in this paper. The main contents and results are as follows:(1) We research the development status and trend about instant messaging at home and abroad, and analyze the problems during the instant messaging softwares used in enterprises. According to the LEAD software application requirements, we give the technical framework of the collaboration office automation of Logging Interpretation.(2) For the requirements on the collaboration platform of logging interpretation application through the NAT, we research and analyze through NAT principle and methods, which realized through NAT by modifying the packet IP addresses and transport layer (UDP or TCP) port and making different ports on the internal address mapped to an external IP address with different port.(3) When remote control software supports multipoint desktop sharing, there is the problem of desktop sharing conflict. In this paper, we research and analyze the kernel structure of VNC (Virtual Network Computing), and propose the model and mechanism to solve multipoint desktop sharing conflict.The mechanism not only avoids desktop sharing conflict, but also protects the local security.(4) Based on analyzing the ICQ source,we design and develop the collaboration platform of Logging Interpretation,which achieved remote desktop sharing, instant text message,file and forder transfer, audio Communications,Video screens and playback, Screen pen,and support off-line text messages, group chat message, file breakpoint continuingly, multipoint remote desktop sharing. In addition, in order to ensure the quality of the software, we should plan overall for software testing scheme.At present, the collaboration platform of Logging Interpretation was put into use in China Petroleum Logging Co.Ltd, and achieved good results.
