Martin, You could downgrade your TCPIP buffer sizes and other TCPIP parameters on your Stack.
However, IMHO I would go with setting up Quality of Service (QoS) mechanisms on your CISCO router, if FTP traffic is impacting your interactive workload. Kevin -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Martin Kline Sent: Tuesday, June 09, 2009 4:13 PM To: [email protected] Subject: Throttling FTP We have some large batch FTP processes that were recently identified as the cause of major network slowdowns for online processing. More specifically, one of our CIP routers becomes a bottleneck when batch FTP jobs start flooding it. We are working on a process to ensure that particular FTP batch processes are run on a system that will not affect the problem router. IFAIR, VTAM has/had pacing options that could help manage just this sort of situation. Does FTP or TCPIP have a similar capability? I found nothing in the FTP configuration about throttling or pacing. Maybe someone else has run into a similar situation. How did or would you deal with this situation? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html This e-mail message and any attachments transmitted with it are confidential and are intended solely for the use of its authorized recipient(s).
