Methods, systems, and apparatus for optimizing communication in a blockchain network. An example method includes establishing, by a first relay node in the blockchain network, a connection with a first blockchain node in the blockchain network in response to a connection request of the first blockchain node; receiving, by the first relay node, a registration request transmitted by the first blockchain node; generating, by the first relay node, a registration event based on the registration request; updating, by the first relay node, a local routing table based on the registration event; and forwarding, by the first relay node, a message of the first blockchain node to another relay node or another blockchain node in the blockchain network that is connected to the first relay node based on the local routing table.

Communication optimization systems of blockchain network, registration methods and message forwarding methods

Embodiments of the disclosure provide a data transmission method. The method can include receiving a first packet sent by a virtual private network user, wherein the first packet carries a first destination address that does not belong to an address range that has been configured for a virtual private network where the virtual private network user is located, converting the first destination address to a second destination address, generating a second packet according to the second destination address and the first packet, and sending the second packet outside the virtual private network where the virtual private network user is located.

Data transmission method and network device

Embodiments of the present invention provide a method for changing configurations at a client device is presented. The configuration changing method comprises: a) sending a heartbeat request message to a network device over a network, wherein the heartbeat request message carries a current first configuration change code of a client device; b) receiving from the network device a heartbeat response message in accordance with the first configuration change code, wherein the heartbeat response message carries a current second configuration change code of the network device; c) sending, in accordance with the first configuration change code and the second configuration change code, a request message to the network device for synchronizing configurations; d) obtaining configuration synchronization information sent from the network, synchronizing configurations of associated services according to the configuration synchronization information, and updating the first configuration change code in accordance with the results of the configuration synchronization.
