Methods and apparatuses, including computer program products, are described for transparent recovery of transport connections. The method includes collecting a state associated with a first connection between a first server and a remote server via a first network socket and transmitting the state from a first networking module to a second networking module. The method includes storing the state, opening a second network socket based on failure of the first networking module, intercepting outbound packets associated with a request to initiate a second connection between the first server and the remote server via the second socket, modifying the intercepted packets based on the state, and transmitting the modified packets to the remote server to elicit an acknowledgement to maintain the first connection. The method includes receiving packets associated with the acknowledgment from the remote server, and modifying the received packets to acknowledge the request to initiate the second connection.

A method and a system for transmitting multichannel data packets are disclosed in the present invention to implement the transmission of the multichannel data packets with the same network socket, and to improve the work efficiency of the multichannel data packet transmission. The method for transmitting multichannel data packets provided in the present invention comprises: creating a network socket which includes a routing cache array for caching the routing information of the multichannel data packets; acquiring the routing information of the multichannel data packets and adding the routing information to the routing cache array; acquiring the routing information of the multichannel data packets from the routing cache array when the multichannel data packets need to be transmitted and sending out the multichannel data packets according to the routing information.

A method for enforcing a network policy is described herein. In the method, a network socket event request from an application executing in a first context is intercepted by an agent prior to the request reaching a transport layer in the first context. A context refers to virtualization software, a physical computer, or a combination of virtualization software and physical computer. In response to the interception of the request, the agent requests a decision on whether to allow or deny the network socket event request to be communicated to a security server executing in a second context that is distinct from the first context. The request for a decision includes an identification of the application. The agent then receives from the security server either an allowance or a denial of the network socket event request, the allowance or denial being based at least in part on the identification of the application and a security policy. The agent blocks the network socket event from reaching the transport layer when the denial is received from the security server. In one embodiment, the method is implemented using a machine readable medium embodying software instructions executable by a computer.

The invention discloses a method for transmitting multipath data packets and a system thereof. By the method and the system, the multipath data packets can be transmitted by a same network socket, thus improving the working efficiency of transmitting the multipath data packets. The method for transmitting the multipath data packets comprises the following steps: the network socket which includes a route cache array for caching the routing information of the multipath data packets is established; the routing information of the multipath data packets is obtained and added to the route cache array; when transmission of the multipath data packets is needed, the routing information of the multipath data packets is obtained from the route cache array, and the multipath data packets are transmitted according to the routing information.

This disclosure provides an automatic causality tracking system that meets real-time analysis needs. It solves causality tracking for cybersecurity, preferably as three sub-tasks: backward tracking, forward tracking, and path-finding. Given a set of threat indicators, the first sub-task yields the system elements (e.g., entities such as processes, files, network sockets, and the like) that contribute information to a set of threat indicators backward in time. The second sub-task yields system elements forward in time. Given two sets of threat indicators, the third sub-task yields shortest paths between them, e.g., how the two sets of indicators are connected to one another. The system enables efficient multi-point traversal analysis with respect to a set of potential compromise points, and using data from real information flows.

A system for buffering data received from a network comprises a network socket, a plurality of buffers, a buffer pointer pool, receive logic, and packet delivery logic. The buffer pointer pool has a plurality of entries respectively pointing to the buffers. The receive logic is configured to pull an entry from the pool and to perform a bulk read of the network socket. The entry points to one of the buffers, and the receive logic is further configured to store data from the bulk read to the one buffer based on the entry. The packet delivery logic is configured to read, based on the entry, the one buffer and to locate a missing packet sequence in response to a determination, by the packet delivery logic, that the one buffer is storing an incomplete packet sequence. The packet delivery logic is further configured to form a complete packet sequence based on the incomplete packet sequence and the missing packet sequence.

The invention provides a standard POE and mandatory non-standard POE integrated powered power supply circuit, which is arranged between a POE network socket and a powered device. The standard POE and mandatory non-standard POE integrated powered power supply circuit comprises a standard power supply module which has a line impedance that conforms to a standard protocol, and when an input voltage is greater than a set value, the standard power supply module is conducted and a voltage inputted by the POE network socket is sent to a DC-DC step-down and voltage stabilization module; non-standard jumper modules, which can perform switching of a non-standard power supply circuit, and without detection, power directly reaches the network socket through a network cable, and then the power is directly sent to the DC-DC step-down and voltage stabilization module; the DC-DC step-down and voltage stabilization module performs voltage reduction and voltage stabilization on an inputted direct current voltage and supplies power to the powered device; an input end of the standard power supply module is connected with the POE network socket, and an output end of the standard power supply module is connected with an input end of the DC-DC step-down and voltage stabilization module; an output end of the DC-DC step-down and voltage stabilization module is connected with the powered device; and the non-standard jumper modules are connected in parallel at the two ends of the standard power supply module. The standard POE and mandatory non-standard POE integrated powered power supply circuit provided by the invention integrates the standard POE and non-standard POE power supply modes as a whole, which can avoid generating different types of equipment repeatedly, and make a power utilization environment of a user to be compatible to the maximum extent.

The invention discloses a communication processing method and device. The communication processing method comprises the steps of respectively establishing network socket based connection between a network server side and each client, and keeping the established connection between the network server side and each client; receiving requests sent by the corresponding clients through the connection, wherein each request carries a uniform resource locator and a request body of a common gateway interface program; constructing a request object based on a request header constructed according to the uniform resource locator and information extracted from the connection; transferring the request object and a constructed response object to the common gateway interface program, and acquiring a processing result of the common gateway interface program from the response object; constructing a response for the request based on a response body constructed by using the processing result, and returning the response back to the corresponding client through the connection. By implementing the communication processing method, the request initiating efficiency of the clients towards the network server can be improved, and the communication bandwidth between the network server and the clients is saved.
