What role does a backward leader play in the peering process?

In the context of the peering process, a backward leader has the important role of relaying files over a high-speed local area network (LAN) connection to another forward peer. This function is crucial because it helps in efficiently distributing files among peers, particularly in environments where speed and bandwidth are significant factors.

The backward leader acts as a conduit, taking advantage of the high-speed capabilities of the local network to ensure that file transfers are conducted promptly, thus reducing the load on central servers and improving the overall performance of the file-sharing process. By forwarding files to other peers, it enhances the distribution network, ensuring that multiple peers can access the required files without each having to rely entirely on the original source.

This role is distinct from other potential tasks in the peering process, such as initiating file distribution, caching files for access, or dealing with network address translation (NAT) settings, which are not the responsibilities assigned to a backward leader.
