A rewriting-based scalable anycast method in NDN is disclosed, comprising: a client sends a first request to the network; an intermediate router forwards the first request to a certain first-level scheduler; the first-level scheduler selects a server group , and rewrite the first request as the second request; the second-level scheduler sends the second request to the second-level scheduler of the selected server group, selects the server, and rewrites the second request as the third request, and Forward the third request to the selected server; the server returns the first response message to the second-level scheduler; the second-level scheduler rewrites the first response message as the second response message, and returns the second response message to the first-level scheduler A response message: the first layer scheduler rewrites the second response message into a third response message, and returns the third response message to the client. The method of the invention can meet the diversified anycast requirements in the NDN without destroying the forwarding logic of the NDN router, and overcome the scalability problem of the anycast.

The invention discloses an anycast method based on rewriting in NDN, comprising: a client sends a first request to a first-layer scheduler; the first-layer scheduler selects a server group serving the first request, and sends the first request Rewrite as a second request, and forward the second request to the second-tier scheduler of the selected server farm; the second-tier scheduler selects the server serving the second request, and rewrites the second request as a third request ; The second-level scheduler forwards the third request to the selected server; the server returns the first response message to the second-level scheduler; the second-level scheduler rewrites the first response message into a second response message, and The second response message is returned to the first-level scheduler; the first-level scheduler rewrites the second response message into a third response message, and returns the third response message to the client. The method of the invention can meet the diversified anycast requirements of the NDN network, without destroying the forwarding logic of the forwarding engine of the NDN content router.

The invention discloses a redirection-based scalable anycast method and system in NDN. The method includes: the client sends a first request to the network; the intermediate router forwards the first request to a certain first-level scheduler according to anycast routing; the first-level scheduler selects a server to serve the first request according to a first preset policy Server group; the first-tier scheduler returns the first redirect notification to the client; the client sends a second request to the second-tier scheduler according to the first redirect notification; the second-tier scheduler selects the service according to the second preset policy The server of the second request; the second layer scheduler returns the second redirect notification to the client; the client sends the third request to the selected server according to the second redirect notification; the server returns a response message to the client. The method and system of the present invention can satisfy diversified anycast requirements in the NDN network without destroying the forwarding logic of the forwarding engine of the NDN content router.

The method and system of the present invention can satisfy diversified anycast requirements in the NDN network without destroying the forwarding logic of the forwarding engine of the NDN content router.

The invention provides a line connecting device. The line connecting device comprises a plurality of connecting plates, wherein at least two circular holes are formed in each connecting plate; a tandem post rotating around the axial direction of the tandem post is embedded in each circular hole; the connecting plates form longitudinal connection and transverse extension by sharing at least one respective tandem post; the circular holes in the same connecting plate communicate with each other through first printing metal wires; a plurality of port terminals are further arranged on each connecting plate; the circular holes in each connecting plate communicate with the port terminals on the connecting plate through second printing metal wires embedded in the connecting plate; and each tandem post is formed by splicing a metal post body with a fan-shaped cross section and an insulated post body. According to the line connecting device, the defect that a toggle switch is liable to be triggered when in use is improved, and the problem of contact extensibility is solved; by adding contacts, the connecting plates are connected in a diversified manner in longitudinal and transverse directions; frequently-used contacts can avoid unstable factors for testing caused by the fact that welding spots are relieved all the time. Meanwhile, the line connecting device can serve as a normally-open or normally-closed switch.
