There are many ways to get a good estimate such as the way you do it. &nbsp;For an app you can write, here's an option:<br />

You can use Zabbix or Nagios for monitoring the bandwidth.

Thank you Anacreo I was able to use your clever solution in an enviornment where I am not able to install any additional network monitoring software or additional protocols.

As an admin of Solaris (8,10) servers over a large network with 30+ sites I need a method of calculating the available bandwidth at times. We primarly use cisco routers. Normally I use a stop watch and a known file size then ftp to compute the bw. Does someone have a better way without installing any additional software?

Calculating available bandwidth

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

IT Administration is the processes and best practices for programming and development, and incorporates methodologies for managing activities and projects. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, extreme programming and various types of agile methodology. The life-cycle "model" is a more general term for a category of methodologies, and a software development "process" a more specific term to refer to a specific process chosen by a specific organization.
