- I'm interested in anything published on traffic characteristics of
- TCP and UDP based applications, including
-
- - distribution of packet size
- - lifetime of a connection
- - characteristics of different types of connection
- - frequency of packet generation over the lifetime of the connection.
-
- Ideally, one could define benchmarks which measured performance of a TCP/IP
- stack in a way reflecting different types of real usage. Has anyone done this?
- I believe that bulk data transfer on a single connection is the usual quoted
- benchmark, using ttcp (I know there are NFS benchmarks around).
-
- Telnet and ftp are examples which are fairly obvious, but NFS, OLTP, etc.,
- etc., would be very interesting.
-
- In addition, is the efficiency of protocol processing best reflected by
- throughput per unit of CPU usage (as reported by ttcp)? Any other factors
- that are relevant?
-
- Thanks
