A preemptive connection pool manager for web-based application collaboration

摘要: Most of web-based applications are free marketing systems. They compete network resources usually in first-come-first-service (FCFS) mechanism. As a big company with thousands applications, Comcast faces how to maximize its revenue through all these applications. Currently, have no collaborations even they considered one system. When the resource limit is reached and increasing capacity not an applicable method, FCFS may degrade critical services running some less important We propose priority-based collaboration solution. Every application has pre-determined priority. occupied, new incoming requests from higher priorities preempt those lower so high priority work can be processed sacrificing low work's performance. Specifically, we implement connection pool manager that admits connections for at cost preempting out when system safety limitation approached. The major win here increase our usability most features during traffic burst exceeding capacity.
