Abstract: Methods and apparatus for efficient data transfer within a user space network stack. 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. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. 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).

Abstract: Methods and apparatus for low latency operation in user space networking architectures. In one embodiment, an apparatus configured to enable low latency data transfer is disclosed. The exemplary embodiment provides a multiplexer that allocates a fixed portion of network bandwidth for low latency traffic. Low latency traffic is routed without the benefit of general-purpose packet processing. In one embodiment, network extensions for low latency operations are described. Specifically, an agent is described that enables low latency applications to negotiate for low latency access. In one embodiment, mechanisms for providing channel event notifications are described. Channel event notifications enable corrective action/packet processing by the low latency application. In one embodiment, mechanisms for providing interface advisory information are described. Interface advisory information may be provided asynchronously to assist in low latency operation.

Abstract: Methods and apparatus for active queue management in user space networking stacks. 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. Additionally, user space networking stacks require a new flow control methodology that is responsive to networking congestion and/or packet loss. For example, embodiments of the present disclosure introduce a flow advisory table that may, for example, utilize an eventing methodology for active queue management in addition to, or alternatively then, legacy active queue management. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack) as well as flow advisory tables (and legacy active queue management).
