Embodiment Construction
[0039] like figure 1 , The present invention provides a design method based on virtual memory pool Darwin streaming media server, includes the following steps:
[0040] S100, the virtual memory module plug-in framework design Darwin streaming media server design approach based on the existing plug-ins:
[0041] After increasing the open character of virtual memory, virtual memory blocks can be used to obtain the characters, character block of virtual memory reset, set the virtual memory protection attribute character corresponding to the character newly added virtual memory virtual memory function interface designed to open up, to obtain free virtual memory block function interface reset function interface block of virtual memory, virtual memory protection attributes further provided an interface function;
[0042] S200, design and newly added plug-in role (that is, above the role of virtual memory and memory protection attributes role) functions corresponding functions, including...

A virtual memory pool design method based on a Darwin streaming media server disclosed by the present invention includes S100, designing a plug-in frame of a virtual memory module based on the original plug-in design method of a Darwin streaming media server: adding a virtual memory role and setting a virtual memory protection attribute role ; S200, designing functions corresponding to the newly added plug-in role, including: designing functions for opening up virtual memory, obtaining available virtual memory blocks, resetting virtual memory blocks, and protecting attributes of virtual memory pools; S300, The role in the aforementioned shared virtual memory pool plug-in is designed as an application program interface according to the rules of the Darwin streaming media server plug-in. This method solves the problem that the original Darwin streaming media server can only use and manage small data objects in a heap memory mode, but cannot use and manage large data objects.
Description
Technical field [0001] The present invention relates to virtual memory cell design method based on the Darwin streaming media server. Background technique [0002] 1, the conventional system Darwin streaming server and data memory heap memory components are used in the embodiment, the heap memory is adapted to manage large number of small objects. [0003] 2, in the commercial Darwin Streaming Server, because the original Darwin Streaming Server does not provide the conversion function can not provide stream leads to different types of clients use, so the original Darwin Streaming Server secondary development to increase conversion stream function when the original heap memory usage can not meet the code stream conversion process memory usage for large data objects. [0004] 3, on a large commercial server heap memory usage will generate a lot of memory fragmentation and unpredictable within the system paging exchange, resulting in server performance exponentially reduce the occu...
