Service access method and apparatus crossing internal and external networks

Abstract

The invention provides a service access method and apparatus crossing internal and external networks. The method comprises the following steps: a service provider provides a registration service message comprising a mapping relation between a service name of service provided by the service provider and address information of the service provider to a service registration center, wherein the address information of the service provider comprises internal network address information expressing a protocol IP and an internal network port number of interconnection between internal networks of the service provider, and external network address information expressing the protocol IP and an external network port number of interconnection between external networks of the service provider. As the service provider registers the internal network address information and the external network address information in the service registration center at the same time, an external network service caller automatically discovers the service provided by the service provider in the internal networks and can directly provide the necessary service for the service provider in the internal networks, and the security is effectively improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and device for accessing services across internal and external networks. Background technique [0002] In the Internet era, in order to ensure that the business system will not be overwhelmed by massive access and at the same time ensure high resource utilization, traditional applications have begun to migrate to the cloud. Except that the operating environment will use cloud hosts, the general technical architecture follows the distributed Distribute Service Framework (DSF for short), because only such an architecture can achieve elastic scaling of cloud applications. [0003] figure 1 Shown is a schematic diagram of the DSF architecture, such as figure 1 As shown in DSF, an independent service registration center is introduced in DSF, so that service providers will register with the service registration center through the intranet, so that service callers can subscribe to ...
