Abstract
Methods and apparatus for memory allocation and reallocation in networking stack infrastructures. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional 'socket' based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack). Due to this disclosed architecture, physical memory allocations (and deallocations) may be more flexibly implemented.
