In distributed stream processing systems, machine fail-stop events are handled by either active standby or passive standby.

In order to solve task scheduling and load balancing problems of distributed search engines, a GNP-based scheduling strategy for distributed crawling and a load balancing method are proposed in this paper. Internet distance estimating mechanism is adopted as a replacement for large-scale network distance measurement, which not only improves response speed of the system, but also reduces loads on WAN...
