resource hierarchy
2.Abstract In order to solve the problems of conventional resource discovery framework, a hierarchy-based model was discussed, which combined super-peer model and contact node, a membership join protocol was introduced, and a resource discovery algorithm was proposed based on Time To Live (TTL) limit and cache list.
3.The paper introduces virtual logistics and the resource distribution of virtual logistics enterprises,studies the virtual logistics resource distribution with grid technology,establishes the hierarchy system structure of virtual logistics resource grid and gives out the resource distribution mode for virtual logistics enterprises.
