A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.

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).

A review and retry mechanism ensures a port channel can be configured to provide and maintain a minimum data speed. A timer-based review sequence reviews the constituent interfaces of a port channel to determine if a minimum speed requirement is met. If the minimum speed cannot be fulfilled, the port-channel member interfaces are un-programmed and removed from the port-channel, rendering the port-channel functionally inactive, thereby preventing network traffic loss. A timer-based retry sequence attempts to program the constituent interfaces. The minimum speed requirement of the interfaces is checked in the next review cycle. If the minimum speed requirement is met, then the review and retry mechanism halts and the port channel continues to remain active; otherwise, the interfaces are un-programmed and the process repeats.

The present disclosure provides a method and an apparatus for processing data. The method includes: establishing a data connection between a local service and a Web client, receiving data that the Web client transmits to the local service through the data connection; and storing the received data to the designated local storage space.

Systems and methods are disclosed that provide real-time pre-trade risk assessments for multiple parties. In one embodiment, systems and methods can be configured to receive a market order data packet, wherein the market order data packet comprises order information for a market order to be made at a liquidity venue. The market order data packet comprises a header portion and a payload portion, and the header portion comprises at least a portion of the order information. An order symbol is determined based on order symbol information in the header portion. Risk parameters are retrieved associated with the order symbol. It is determined whether or not a risk threshold is exceeded based on the risk parameters and the order information. A final market order data packet is generated for transmission to the liquidity venue based on the determining whether the risk threshold is exceeded.

Provided is a connected gateway server system for real-time vehicle control service that includes a vehicle terminal mounted on at least one vehicle; a gateway server relaying communication with the vehicle terminal; a connected gateway server for controlling a vehicle and acquiring a vehicle information in the form of REST API for each user through communication with the vehicle terminal, delivering a control command, a response information, and the vehicle information to the user's platform that has been validated as an API form, storing a terminal connection state information, an API authentication information, the vehicle information, and a user information, and performing a confirmation of update state and an update request of vehicle terminal; and an user platform for verifying validity in an API token manner through communication with the connected gateway server, fetching a necessary vehicle information in the API form or issuing the control command of vehicle.

It is often necessary to securely transfer data, such as authenticators or authorization tokens, between programs running on the same end-user device. The teachings hereof enable the pairing of two programs executing on a given end-user device and then the transfer of data from one program to the other. In an embodiment, a first program connects to a server and sends encrypted data elements. A second program intercepts the connection and/or the encrypted data elements. The second program tunnels the encrypted data elements (which remain opaque to the second program at this point) to a server, using an encapsulating protocol. This enables the server to receive the data elements sent by the first program, decrypt them, and provide them to the second program via return message using control fields of the encapsulating protocol. Once set up, the tunneling arrangement enables bidirectional data transfer.
