摘要： 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.

摘要： 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.

摘要： 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.
