A method for creating a data transmission entry and a related device are provided, which are used in the communication field. The method includes: a source node receives a first packet sent by a destination node, wherein content of the first packet includes a destination address of a data packet; and the source node creates, depending on whether the destination address of the data packet is an address of a service supported by the source node, an entry associated with the first packet.

Method for creating data transmission entry and related device

A data packet sending method includes: before a PMTU of a path is probed, sending a data packet according to a minimum MTU stipulated in the IPv6 protocol; and after the PMTU of the path is probed, sending a subsequent data packet on the path according to the probed PMTU of the path.

Data packet sending method and apparatus in IPV6 network

An X2 service transmission method and a network device are disclosed. The method includes if a first IPsec tunnel is unavailable, detecting, by a first base station, whether a second IPsec tunnel between the first base station and a security gateway is available, where the first IPsec tunnel is an IPsec tunnel established between the first base station and a second base station, and the first base station can transmit X2 service data with the second base station through the second IPsec tunnel; and transmitting the X2 service data through the second IPsec tunnel if the second IPsec tunnel is available.

X2 service transmission method and network device

The present invention relates to the field of communications technologies, and in particular, to a data packet sending method and apparatus in an Internet Protocol IP version v6 network, so as to resolve a problem that a data packet may be always discarded before a PMTU of a path is probed in a current IPv6 network. The method includes: before a PMTU of a path is probed, sending a data packet according to a minimum MTU stipulated in the IPv6 protocol; and after the PMTU of the path is probed, sending a subsequent data packet on the path according to the probed PMTU of the path. The method ensures that the data packet can pass through a network device having any MTU on the path, so as to ensure that the data packet can be received by a destination receive end.
