Abstract
Disclosed are methods and apparatus for handling FTP (file transfer protocol) control packets. In general terms, mechanisms are provided for facilitating FTP sessions between devices utilizing different protocols, such as IPv4 and IPv6. For example, FTP control packets from an IPv6 client to an IPv4 server are handled to facilitate such communication. Likewise, FTP control packets from an IPv4 client to an IPv6 server are handled to facilitate such communication. Communication is also facilitated when either or both of the client or server is in the form of a dual-stack device. To facilitate FTP session between devices having different protocols, FTP control packets between two different protocol devices are translated from one protocol to another protocol when required, e.g., from an IPv6 to an IPv4 format or visa versa.
