Abstract: Disclosed are an input/output proxy method and apparatus for a mimic Redis database. Through a pseudo server module, it is ensured that the interface of the Redis database is consistent with the external interface of the native Redis, so that it is convenient to implant the Redis database into arbitrary Redis application scenarios; the isolation of the modules inside is realized by independent processes, thus facilitating independent development, maintenance and expansion; and the synchronization function is integrated into the input/output proxy to achieve resource reuse; for the synchronization function, the random credit attenuation mechanism is cleverly utilized to ensure the synchronization function while taking into account the saving of resources.

Abstract: The present invention relates to the technical field of computer networking, in particular to an ID/location hybrid forwarding method based on source routing, including a message format based on an extension header of a MobilityFirst protocol, a source routing forwarding mechanism based on ID identifiers and a source routing forwarding mechanism based on location identifiers. Through the method of the present invention, the source routing forwarding mechanism based on ID identifiers can be adopted in the access domains of the MobilityFirst network to realize the internetworking of intra-domain networks, and the source routing forwarding mechanism based on location identifiers in the core domain realizes the interconnection of inter-domain networks; the method greatly simplifies the processing flow of the data plane of the MobilityFirst network, and meanwhile reserves the design that the ID identifiers and the location identifiers are separated, thereby effectively supporting intra-domain and inter-domain mobile data forwarding.

Abstract: An incremental compiling method and an incremental compiling system based on a heterogeneous device. The method comprises: a user using P4 to develop a network program, checking the syntax and semantics of the network program and converting into an intermediate representation; allocating intermediate representation files according to constraints such as the functions and resources of the heterogeneous device; then, transforming the network program into different rule expressions of the heterogeneous device according to the constraints of the heterogeneous device, flow table entries and the like, and loading the on different rule expressions to a target device; when the user needs to deploy network functions incrementally, the user only needs to write new network programs and regenerate rule expressions; by comparing and analyzing the old and new rule expressions, a rule expression that can be loaded on heterogeneous device is formed, and the incremental deployment of network functions is realized.
