IPVanish released version 22.214.171.124 this week allowing the user to choose from TCP or UDP IP traffic. The new radio button added for user selection gives IPVanish VPN users an option to control the speed of data transmission based on what applications they are using.
TCP (Transmission Control Protocol) is used for applications that are not time sensitive and is connection based meaning communication makes it’s way across the Internet from one computer to another. The header size of TCP is 20 bytes. Examples include HTTP, FTP and SMTP.
UDP (User Datagram Protocol or Universal Datagram Protocol) used for applications that require a fast transmission of data such as games. UDP is faster than TCP because it does not perform error checking for packets. Also unlike TCP there is no guarantee that the messages will reach the destination. The header size is 8 bytes and examples include DNS, DHCP and TFTP.
Current IPVanish users will be prompted to upgrade to the latest version of the service upon launch. If you are currently not using a VPN service, read about the benefits here. For a small monthly fee you will gain priceless peace of mind knowing that your online identity and data are secure.[bigblue url="http://www.vpnmag.com/ipvanish-review/"]Check it now[/bigblue]
