    The application behaves like a client and a server at the same time.1. The server role. It waits for a message from client. When a message is received it processes it. The 1st message would be a query, asking if a certain file exists on the system The response should be YES/NO The 2nd message would request the file The server should start sending the file in parts. The size of each part would depend on the size of the file. You need to decide what should be the size of each part. Your design should consider lost parts during transmission, out of order parts arriving, and finally some metho to indicate that the file trnsfer is complete.2. Client role There should be a command interface where you are trying to get a file using file name. (for added functionality, consider partial file name, or just file types - .jpg, mpeg etc.) The client should send a message to N servers. The client recevies replies from N-X servers. Some o the replies will be "YES" others will be "NO" Select one of the servers that replied "YES". Request the file from the server.The file may arrive in parts. reassemle the file.

    Hi , I"m looking to hire a freelancer for web designing and online store setup

  • $526 USD 16 days ago

    We house sign makers trading online and require a cross browser design tool for our site visitors to create their own house signs online and submit the design to us so we can make the sign for them. The tool must work cross browser on all devices. We feel HTML5 with CSS should be the way to do this. We have purchased a full licence of a product design tool a few months ago which has potential but does not fulfill all our requirements. You can check out the script at the following link on our website: script can be adapted or we can have a bespoke tool made at the right price.Ideally we would like our site visitors to be able to choose from any of our house sign base plaques with pre-formatted text and numbers in the designer and then easily change the text and numbers to their own wording. They should then be able to dynamically scale the text and change the fonts offered in a font list. On some of our oval shaped house signs the user should be able to arch the text dynamically to for a top curved path and a bottom curved path and be able to dynamically adjust the letter spacing. The customer must be able to save their design as a jpg proof and submit it as an order to us. We need to receive the jpg image by email and also access a file in either AI, DXF or PDF format with vector outlines of the design submitted so we can import it into our house sign making software.. Please contact Gerry for further details
