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: An apparatus and method are described for collecting and evaluating statistics for different network addresses and/or subnets when establishing network connections. For example, a method according to one embodiment comprises: receiving a set of potential network addresses for establishing a connection to a remote host; evaluating routing statistics associated with each of the potential network addresses; prioritizing the set of potential network addresses based on the evaluation; and initially attempting to connect to the remote host using the highest priority one or more network addresses.

Abstract: A method and apparatus of to negotiate access with a captive network is described. In an exemplary method, a mobile client detects, with a network interface, a network. The mobile client associates with the network, where associating allows the mobile client to communicate with the network. In addition, the mobile client probes the network by requesting a web page, where the web page is independent of the network. In response to the web page request, the mobile client receives a capture web page. The mobile client determines the type of authentication used for the network based on the received capture web page.

Abstract: A client device having a networking layer and a network driver layer for transmitting network packets comprising: a plurality of transmit queues configured at the network layer, each of the transmit queues having different packet service classifications associated therewith; a classifier module for classifying packets according to the different packet service classifications, wherein a packet to be transmitted is stored in one of the transmit queues based on the packet service classifications, wherein one or more of the traffic service classifications comprise opportunistic traffic classes and other traffic service classifications comprise non-opportunistic traffic classes; and a socket layer comprising socket transmitting data from an application associated with each traffic service classification, wherein a socket associated with an opportunistic traffic class is automatically suspended in response to detecting a network interface of the client device being throttled.

Abstract: Multiplexed data stream protocols are described. In one embodiment, a method to provide a multiplexed data stream protocol includes packetizing a data stream to provide packets with headers and transmitting the packets through an interface which is not designed to use Internet Protocol (IP) addresses. The headers contain data for flow control and sequencing and are associated with a port for an application, and the headers allow multiple applications to maintain an arbitrary and changeable number of multiple concurrent sessions through the interface. The headers may be Transmission Control Protocol (TCP) like headers and may not include IP like headers. Systems, computer readable media, software architectures and other methods are also described.

Abstract: File protocols for transaction based communication are described. In one embodiment, a method to provide a file transfer protocol includes receiving packets containing headers, the packets being received at a first network stack software through an interface, and extracting data from he packets and reconstructing a file from data in the packets. The extracting may be performed by a first network stack software, and the interface is not designed to use Internet Protocol (IP) addresses, and the headers contain data for flow control and sequencing and are associated with a port for a file transfer application, and the headers allow multiple applications to maintain multiple concurrent sessions through the interface, which may be a USB compliant or BLUETOOTH compliant interface. Systems, computer readable media, software architectures and other methods are also described.
