A quick-assembly seat includes a seat body, a clamping assembly and a driving assembly. The clamping assembly includes a clamping member and a touch member which are slidably connected to the seat body. The driving assembly includes a first driving member and a third driving member, where one end of the first driving member and one end of a third driving member are connected to the seat body, and the other end of the first driving member and the other end of the third driving member are respectively connected to the clamping member and the touch member. The clamping member is configured to move along a first direction toward an inside of the seat body, so that the first driving member accumulates a driving force, and the third driving member releases a driving force to drive the touch member to be clamped with the clamping member.

Quick-assembly seat, quick-release assembly and photographing apparatus

A quick-assembly component includes a quickly-assembly plate and a quick-assembly seat. The quick-assembly plate has a first surface and a second surface oppositely arranged along a thickness direction of the quick-assembly plate. The first surface is provided with a recess; a side wall of the recess is provided with a clamping slot communicating with the recess. The quick-assembly seat includes a seat body, a touch assembly, and clamping assemblies. The touch assembly includes touch members that are movable relative to the seat body along the thickness direction of the quick-assembly plate. The clamping assemblies each include a clamping member and a first restoring member provided between the clamping member and the seat body. The clamping member is movable relative to the seat body to allow the first restoring member to accumulate and release a restoring force.

A method for backing up a TCP connection includes a data transmission process and a data receiving process. The data transmission process includes obtaining, by an AMB of a transmitting end, boundary information of data; and backing up the data and the boundary information of the data to a SMB of the transmitting end. The data receiving process includes backing up, by the SMB, data received from a peer side of the TCP connection and the boundary information of the data received by the peer side to the AMB; and deleting the data received by the peer side from the data backed up by the SMB during the transmission process according to the boundary information of the data received by the peer side. The disclosure also provides an apparatus for backing up a TCP connection.

A method and a system for process upgrade are disclosed. A source process implements data interaction, via a socket interface, with a far end entity connected with the socket interface. When the source process intends to upgrade itself, the source process copies its process data to a target process and determines if the data from the far end entity received via socket interface is complete. If it is determined that the data is complete, the source process ceases data interaction with the socket interface and copies the received data to the target process. After the data is copied, the source process sends an upgrade and switch indication to the target process and enables the target process to send an upgrade and switch request to the socket interface. The socket interface then switches a socket interface service to the target process. Accordingly, the technical solutions according to the present invention realize a reliable and smooth process upgrade without disconnecting the socket connection.

A message synchronization demarcation method includes: a backup board receives a message of an opposite terminal from an interface board; the message is copied to a main board; the main board processes the message, copies it to the backup board through the buffer unit and transmits the data. Also a message synchronization demarcation system is provided. The data backup between the main board and the backup board is performed through the buffer area without occupying the transport layer resource, so the data flux of communication channels is reduced, the payload is lowered, and the backup steps of messages between the main board and the backup board is simplified. Using the present disclosure, the received message can be demarcated, and the accuracy of message transmission is further improved.

Method and system for synchronization of packet

The present invention discloses an 802.1X protocol-based multicasting control method. According to the method, an authenticated subscriber intercepts the message while sending a request message for joining in a multicasting group, then obtains the port and MAC address information from the intercepted message, searches corresponding subscriber account information from the authenticated data according to said port and MAC address, then authenticates the subscriber's account number and multicasting IP address, and adds the subscriber to the multicasting group after successful authentication; therefore, controlled multicasting, authentication of the legality of adding to multicasting, and accounting can be achieved according to the method, which can also protect existing investment and compatibility with existing software of the subscriber.
