Once the applet is launched enter username and password in the login dialog and press connect. When the operation is completed successfully the login dialog will disappear and you will be connected to the auction taking place at the servlet specified in the agent text box of the login panel.

From the “View” menu you  can select different GUI components that will allow you to specify auction configuration
parameters, monitor the auction as well as manually bid:

• News: a scrolling banner to update you on the current state of the auction and on the bidding process
• Valuation: a GUI for selecting how much you value the bandwidth, i.e. how much you are willing to pay. Since theprice will change depending on the quantity of bandwidth the valuation is represented by a curve A choice menu allows you to select among few predefined curves:
• Linear: a straight line: the value per unit of the bandwidth is independent of the amount of bandwidth requested.  Parabolic: a parabolic curve the value per unit decreases as the quantity requested increases.
• Logarithmic: a logarithmic curve
• Roberts: a valuation model for wholesale Internet bandwidth based on  L. G. Roberts  (see "Beyond Moore's Law: Internet Growth Trends", IEEE Computers, January 2000)
• Web Valuations: bandwidth valuation for a web server. A web master  can specify the average file size, hits per month, desired delay, and value per hit, those values are converted into a bandwidth valuation curve.
You can change the parameters of these curves by selecting the appropriate values in text boxes or changing the curve with the mouse.

• Budget:  Specify your budget (i.e. the maximum total amount that you are willing to pay)
• Strategy: a GUI for selecting the algorithm used by the bidding agent to send the bid based on your valuation and total budget. The strategy displays your bid (a certain quantity at a certain price), the bid fee, and the bidding interval i.e. how frequently the bid is sent to the server.  A choice menu will allow you to select among the following:
• Truthful:  The strategy that bids the truthful best reply following the derivative of the valuation curve : It will only submit the bid if utility will be increased by at least epsilon. (see Proposition 1 of  the PSP paper)
• Aggressive: Set a random price, get as much quantity as possible without exceeding budget.  If this new bid is better  than  current bid (i.e. increases the utility function) , then it is submitted. This strategy is suboptimal and should not  be used.
• Manual: Explicitly specify price and quantity of your bid.
• Bid Graph: You can monitor the auction.
• The blue dots show your opponents' bids
•  The magenta (purple) dot shows your allocation (what you would get) from the current profile of bids. The rule (formula)  that computes your allocation from the bids is the Progressive Second Price Auction™ (patent pending).
• Your budget is shown by the magenta dotted line (not shown if budget is unlimited) .
• You can only get the leftovers from higher bidders; the buyer who bid for the highest price gets the quantity  he bid for; the next ranked buyer gets what he bid or what's left, whichever is smaller, etc. So during the bidding, the dark surface shows what you can get given the current opponents' bids.
• Allocation: GUI to display the current allocation of your bandwidth (quantity and price per unit), the time left to the end of the current auction and the total paid from the start of the bidding session (since your latest connection).
• Unit: GUI to change the units of: quantity, price and time.
• Allocation Graph: A rolling graph plotting your allocated quantity (green) and price (yellow) over time.
• Bid Graph: A rolling graph plotting your bid quantity (green) and price (yellow) over time.
• Utility: A rolling graph plotting the utility function.
• Upload Agent: the URL  to which the mobile agent can be uploaded.

From the  “FILE” menu you can:

• Load/Save configuration parameters from/to an XML format file.
• Upload the  mobile agent to a different URL so that the agent will keep bidding from a different computer.
• Download the parked mobile agent from a URL.
• Get Account information: get from the server the current market price, the session bill and the total bill.
• Exit the current session.
