Port forwarding is a commonly employed networking function related to game speeds. Port forwarding allows redirection of computer signals targeting specific electronic pathways. The objective of port forwarding is to achieve speed gains in the context of gaming or downloads. When port forwarding happens, computer signals reach your device faster than it would have been otherwise possible, cumulatively adding to the dramatic increases in speeds.
A Technical Explanation of Port Forwarding
There are approximately 65,536 paths available for computer signals to travel inside a network cable or a wireless network adapter. Each of these paths is associated with a port. A computer signal is composed of many tiny bits that travel along these paths in the form of packets. The speed of transfer of a typical packet can reach up to thousands of kilometers per second.
Pathways also feature intersections and signals traveling along pathways must find an open port whenever they encounter an intersection. Ports identify the packets and determine whether they must be allowed to pass through the intersection or not based on present criteria. If a packet is unable to travel across a particular intersection, it should look for another port which allows its transit. In this way, the packet continues to look for open ports until it is successful in reaching its destination.
An important advantage of intersections is that they identify packets and allow only trusted data to pass through them. When hackers send malicious packets, they can be easily filtered at the intersection and rendered as random electrons. This process is known as packet filtering or packet snipping.
The Most Common Ports Accessed by Computer Packets
Software programs installed in a computer system send packets through specific ports. Ports are allocated for software programs, in accordance with accepted programming standards. A router is configured to enable packets to pass through these ports to allow seamless transfers, without compromising computer speeds.
Some of the most common ports associated with frequently used software and protocols include port 80 for HTML pages, port 21 for FTP, and port 110 for POP3 email support. Besides these ports, port 3724 is the designated port for World of Warcraft, port 1024 for Everquest, port 6881 for Bit Torrents, and ports 6901, 6891-6900 for MSN Messenger.
Configuring Your Network Router for Port Forwarding
A network router can be set up to allow packets to travel along specific electronic lanes. This process ensures that packets do not have to be verified at every port until they find an open port, suitable for their passage. The router instead identifies the designated path for the packet based on the configuration information and speeds up the process considerably.
The router just redirects traffic to eliminate time lost in verifying each and every packet. Even though identification of packets lasts only a few milliseconds, the whole process of scanning multiple packets can slow down your system by several seconds. Speed optimization in the case of port forwarding can translate into hours gained in terms of download times.
Learning to Program Port Forwarding
It can be a difficult task. However, when done correctly, through self-learning assisted by online tutorials, port forwarding can improve bit torrent download speeds considerably.
