2.3 Product Functions

The functionality of FCM is split between the two separate components - the Router and the Receiver. The FCM component provides the following functionality:

• The TCP window size on a Receiver will be determined by the algorithm specified in section 11 based on the queue length information being gathered from a Router.
• A Router will send information about $p(q)$ (see Glossary, section 10) to all hosts that receive data forwarded by the Router.

The SAM component provides the following functionality:

• A Graphical User Interface (GUI) will allow the user to create a network log file with information relevant to network performance based on network traffic over a period of time.
• A GUI will allow users to perform statistical analysis on network logs.
• Statistics will be able to be produced for a single TCP stream, or multiple streams.
• Graphs will be able to be exported to external files, in Postscript format.
• The following analyses will be available for use:
  • Plot Data
  • Mean
  • Variance
  • Spectral Analysis
  • Autocorrelation
  • CDF
  • PDF
• Analysis will be able to be performed on the following raw data:
  • Window size
  • Queue size
  • $p(q)$
  • Throughput
  • Number of packets transferred
