Embodiments of the present invention provide a clock synchronization method and device. The method includes: receiving, a preconfigured multi-protocol label switching (MPLS) capability parameter and a traffic engineering (TE) capability parameter, and establishing, based on the MPLS capability parameter and the TE capability parameter, an MPLS tunnel interface; establishing, an MPLS TE tunnel whose bidirectional paths are consistent between the first clock synchronization device and a second clock synchronization device; and performing, clock synchronization message interaction with the second clock synchronization device through the established MPLS TE tunnel. In the embodiments of the present invention, by establishing the MPLS TE tunnel whose bidirectional paths are consistent between the first clock synchronization device and the second clock synchronization device which perform clock synchronization message interaction, symmetry of clock synchronization message interaction paths is ensured, and therefore, a time error in clock synchronization resulting from asymmetry of the paths is avoided.

Clock synchronization method and device

A TCP proxy insertion and uninstall method is provided, including: during establishment of a TCP connection, forwarding a TCP connection establishing packet between a TCP client and a TCP server through an L3, and recording option information and sequence number information of the TCP connection establishing packet; performing determination on a packet according to a proxy policy; forwarding the received packet if it is determined that no proxy process is required for the packet, and updating the recorded sequence number information according to sequence number information of the received packet; and generating a client pseudo socket and a server pseudo socket according to the option information and sequence number information if it is determined that a proxy process is required for the packet, terminating the received packet by adopting the client pseudo socket and server pseudo socket, processing the terminated packet through an L7 and forwarding the processed packet.
