摘要： An initial sequence number generator is provided that prevents the local server from being attacked while maintaining reliable data transfer. A random intermediate value is created that is unique to each connection identifier and is combined with a random value created from a global counter to generate the initial sequence number. The counter capable of monotonically increasing by both a fixed and variable amount for ensuring that the same connection identifier does not have data collisions from competing sequence numbers within a predetermined period of time, and also to ensures randomness of the initial sequence number on a per connection basis for preventing attacks on the local server.

摘要： Handles associate respective native resources with an application that utilizes a library to call for the native resource. Each handle is created to track a native resource that has been allocated to an application. All native resources associated with the application are freed by examining the handles to find those native resources still being held by the application after they are no longer being used, or when that application has been, or is being, terminated. If a native resource is requested by the application and found to be unavailable, the handles are reviewed to collect allocated native resources that are found to be unneeded by their respective applications. A collected native resource corresponding to the requested native resource is thereby made available to be reallocated to the requesting application.

摘要翻译： 处理将各自的本机资源与利用库来调用本地资源的应用程序相关联。 创建每个句柄以跟踪已分配给应用程序的本机资源。 与应用程序相关联的所有本地资源都可以通过检查句柄来释放，以便在不再使用应用程序之后，或者当该应用程序已经或正在被终止时，查找应用程序仍在持有的本机资源。 如果应用程序请求了本机资源，并发现该资源不可用，则会对手柄进行审查，以收集被分配的本地资源，这些资源被各自的应用程序所不需要。 因此，与所请求的本地资源相对应的收集的本地资源可用于重新分配给请求应用。
