[0025] When the STA switches from MPP1 to MPP2, there are still data received by the STA in the forwarding queue of MAP1, but once the STA is disconnected from MAP1, MAP1 will delete the STA list information, and MAP1 does not store the STA The relevant information of MAP2 that will be accessed in the future, so when the data packet sent to STA reaches MAP1, MAP1 directly discards the data packet, resulting in packet loss

The invention discloses a method for switching among wireless Mesh network fields, comprising the steps as follows: an STA sends switching requirement information to an MAP1 connected in currently, and the information is transmitted on an MPP2 (Massively Parallel Processor2) by an MAP1 and an MPP1; after the STA receives switching response information containing a target IP (Internet Protocol) address of the STA and an IP address of the MAP2, the connection between the STA and the MAP1 is disconnected, and the STA enters an MPP2 field to build connection with the MAP2, or according to a current network environment, the STA selects a mesh network access point P-MAP in the MPP2 field to build connection with the P-MAP; and the MAP1 sends a packet received by the STA in a transmission list of the MAP1 to the MAP2 or the P-MAP. By adopting the method, the STA can be ensured to switch from one field of the MPP to one field of another MPP, and obligates resources for the STA in advance, thereby avoiding the loss of the packet.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for inter-domain switching of a wireless Mesh network. Background technique [0002] IPv6 (Internet Protocol Version 6) is the next-generation Internet protocol version designated to replace IPv4. This protocol is mainly used for packet switching. Since IPv4 has been allocated on February 3, 2011, the industry is all targeting IPv6. Compared with the 32-bit IPv4 address, IPv6 is 128-bit, which not only provides a larger address space, but also the protocol design in IPv6 is more reasonable than that of IPv4. [0003] Wireless Mesh networks provide users with access services that are more stable than single-hop networks. Wireless Mesh network technology is a new type of wireless mobile communication technology for IP-based access, suitable for regional environmental coverage and broadband high-speed wireless access. The wireless Mesh network is based on the mutu...
