Radar Product Central Collection and Dissemination Service (RPCCDS) Status • RPCCDS product latency/loss during peak summer hours • Observed when throughput was >133K products/hr and >2.5 G bytes/hour • TOC migrated the RPCCDS to a faster virtual server, but still having problems • Products are now shed when internal backlog queues reach thresholds • Loss of products to RPCCDS users and NCDC Archive (up to 20%) • Product shedding is a temporary measure to prevent excessive latencies and will be eliminated as soon as the RPCCDS problem is resolved • TOC considering software rewrite – should know more later this month 8/4/2014 NWS Partners Meeting
