Narrowband Weak Connection Adaptive Service Framework Device and Service Calling Method

Abstract

The present invention provides a narrow-band weak connection self-adaptive service frame device and a service calling method, which relate to the technical field of service architecture. The frame device includes: a client, a service gateway and a server; the client and the server are served through the service gateway Adaptive transmission of messages; the service gateway includes: an information distribution agent module, which is used to calculate the size of the network bandwidth, and adaptively transmits the service message according to the size of the network bandwidth; a service addressing module, which is used to provide the client with Inquiry of the calling address of the server; the protocol adaptive module, used to select the corresponding transmission protocol according to the size of the network bandwidth, and encode and compress the service message; the cache module, used when the throughput of the data generated by the service gateway is greater than that of the network When the throughput of the bandwidth is exceeded, the service data packets exceeding the throughput are cached locally in the form of queues. Compared with the existing technology, it realizes reliable invocation of services in high dynamic, weak connection, and low bandwidth environments.

Description

technical field [0001] The invention relates to the technical field of service architecture, in particular to a narrowband weak connection self-adaptive service framework device and a service calling method. Background technique [0002] In the current era of rapid development of Internet applications and WEB information systems, more and more application systems have emerged as the times require. At present, the interconnection and invocation between applications adopt Service-Oriented Architecture (SOA), but traditional SOA services It is based on high-speed bandwidth, that is, the network bandwidth is greater than 1KMbps, the link connection is stable, and the environment and architecture rely on fixed center addressing. In an environment where the network bandwidth is limited and the communication link is unstable, it is difficult for the traditional SOA-based service framework to achieve reliable invocation of services. Therefore, it is necessary to improve the service...
