Has anyone had any experience in deploying platforms to control P2P traffic for bandwidth optimization?
This was selected as Best Answer Blocking P2P is ~not~ as easy as “simply block the protocol at the router or firewall”. Most P2P applications implementations are somewhat more intelligent and run over well known outbound used ports like…… 80/tcp (HTTP) or 443/tcp (HTTPS), based upon the previous answer just block those ports/protocols and see how well that works in your organization. Limited outbound access (port/protocol) will eliminated some of the low hanging fruit and a lot of the older P2P solutions, but not the newer implementations. Also I believe if you attempt to enable QoS on http/s traffic that will also have the same affect as blocking traffic, a lot of unhappy people within the organization. Because firewalls and caching devices alone cannot completely block P2P access, a tiered approach is recommended. In order to effectively control P2P access within an organization, access controls must be implemented at the network, transport, and application layers. Early P2P cli
