The embodiment of the invention discloses a BGP dynamic transferring method and a device. the method comprises the following steps: establishing a virtual neighbor and a backup TCP connection according to the received dynamic transferring order; obtaining configuration information of a transferring neighbor on a border gateway protocol (BGP) and route information of the transferring neighbor on the BGP in a first inlet route table, storing the configuration information into the virtual neighbor, storing the route information of the first inlet route table into a second inlet route table of the established transferring neighbor on a target border gateway protocol and selecting routes according to the route information stored in the second inlet route table; and receiving message data of the transferring neighbor, corresponding to the TCP on the BGP, to the backup TCP connection. The embodiment of the invention can realize the dynamic transferring of the Peer among distributed BGPs, and ensures the connection of the message and the business during the transferring.

The invention discloses a method of uplink and downlink message routing of a service gateway of internet of things, wherein the method of uplink message touting include: enabling a terminal to send an uplink message to a terminal access-in adaptation layer subsystem; analyzing a terminal protocol by the terminal access-in adaptation layer subsystem, and enabling the uplink message to be changed into an interior message of the service gateway of the internet of the things and sent to a routing control module of a core layer subsystem; enabling the routing control module to query a routing table, and enabling the uplink message to be sent to a corresponding network element according to different order relationship; and enabling a capability gateway module and a real-time data distributing module to supply the received uplink message for an application subsystem to apply. The technical scheme is adopted, the method of the uplink and downlink message routing of the service gateway of the internet of things is elastic and flexible in framework, good in expansibility, capable of achieving multi-granularity order relationship, wide in application, good in application and customization capability and beneficial for the application and development.

The invention discloses a service message processing method and equipment based on a network address translation protocol, which are used for solving the technical problem that network address translation loopback can be realized only by carrying out an exchange chip flow twice through an internal loopback port in the existing message translation. The method comprises the following steps: receiving a service message from a host and/or a server of a local network through a switch; according to the first access control list rule, carrying out the source address conversion on the service message, obtaining a corresponding next skip list index through a routing table, and according to the second access control list rule, carrying out the destination address conversion on the service message to obtain a corresponding next skip list index; and determining an exit corresponding to the next hop address according to the next hop list index corresponding to the second access control list rule, thereby realizing forwarding of the service message. According to the method, access control list rules are inquired in parallel in a plurality of blocks of the access control list, so source address translation and destination address translation are performed at the same time.

The invention discloses a method for automatically searching network element devices. When a user instructs a network manager to initiate a search for the network element device, the network manager directly sends a protocol packet in a fixed format to all gateway network element devices associated with the user instruction through a communication layer protocol ; The gateway network element device that receives the fixed-format protocol packet queries the information in the routing table of the path to the specific network terminal, and generates a fixed-format response protocol packet for the queried information that meets the requirements of the fixed-format protocol packet; the gateway network element The device returns a fixed-format response protocol packet to the network management system. The response protocol packet contains at least the unique identification information of the network element device that the gateway network element device can reach; The results are displayed to the user. The method for automatically searching network element devices provided by the invention greatly simplifies the search process, improves the efficiency and reliability of the search, and improves the scalability of the search process.
