Getting Started with IPv6
Is IPv6 hype or reality? How soon should we start to think about migration? We have heard of the shortage of IPv4 addresses which will supposedly force us to use IPv6. How ready are the platforms we use daily for IPv6?
That is, if we need to migrate, can we really do it? Then, in terms of the Internet, how ready is it for IPv6?
Ten Commandments of TCP Performance
The Ten Commandments of TCP/IP Performance, is a distillation of hard-won experience. Monitoring and tuning TCP networks
on the mainframe is complex for the basic reason that each network is a mixture of many applications and pieces of hardware.
One-Minute Stack Analysis
The principles presented by the One-Minute Manager (Kenneth Blanchard and Spencer Johnson) apply equally well to TCP network analysis. Regularly finding and fixing the problems in one minute of
TCP stack activity can keep your network running smoothly. If you find and fix the problems in the packets transferred in
one minute from your TCP stack every week for a year, you will have found and fixed hundreds of problems. You will have the
added benefit of getting to know the traffic and kinds of problems on your TCP network intimately. The problem lies in that
on large systems, one minute can produce hundreds of thousands or even millions of TCP protocol records. How to look at all
this data -- and, most importantly, why?
TCP/IP Chargebacks
Chargeback is a good way to control TCP/IP resource usage, save money, and automatically enforce performance goals by
rewarding efficient use of CPU and other scarce resources.
SNA Security: Full of Holes?
Is your network secure? These user stories will help you determine whether you should investigate SNA security on your network,
and/or what the price may be if you decide to do nothing.
