PeteDotCom -> Networking -> Networking -> Request For Information ->   RFI (Request for information) When you are considering to build a new network but don't know which equipment from which suppliers to use then you send out a request for information (RFI) to the suppliers with the specifications that you require to the new network and the suppliers which send you back information on which of their products will suit you best. RFC ( can't remember what the acronym mean) When putting through the RFC, you sometimes don't want to have the small bidders waste your time, one way to keep them out is to create a Vendor List. Vendor list could state the names of the companies you would only accept tender, or state the minimum size of the tender, or specify that you require 24hrs on call maintance.  When putting through the RFC and the requirements are based on price, always remember to state "new" - you don't want second hand bidders. State that no substitute can be made from your specification and also state that the parts need to be current, i.e. with in the last year.
