<p>Embodiments of the present invention provide a service routing method and a system on a service overlay network, which relate to the field of communications, and may efficiently adapt to the dynamic characteristic of the service overlay network. The routing method includes: a current service routing entity receives a service request, and the current service routing entity selects, according to the routing code of a home service routing entity of the service, from its own service routing table, a second service routing entity corresponding to a routing code that has a most adjacency relationship with the routing code; if the second service routing entity is not the current service routing entity itself, the current service routing entity forwards the service request to the second service routing entity, wherein the service request carries the routing code of the home service routing entity; setting the second service routing entity is as the current service routing entity, and performing step A until the second service routing entity selected by the current service routing entity is the current service routing entity itself; and if the second service routing entity is the current service routing entity itself, setting the current service routing entity as a first most adjacent service routing entity, the first most adjacent service routing entity obtains service registration information of the service from its corresponding service registration entity, and the first most adjacent service routing entity sends the service request to a service provider according to an endpoint address of the service provider in the service registration information.</p> |
