Abstract: Dynamic rate limiting of background traffic to alleviate congestion in the access network is enabled. ICMP echo round-trip times and ICMP losses to a nearby node outside the local area and just beyond the divergence in. end-to-end paths are measured, allowing unambiguous discrimination of nearby from distant congestion points. Using round-trip time samples, either short-run delay or short-run variance in delay can be measured to estimate congestion. When combined with an appropriate control law, background traffic can be rapidly reduced to allow interactive traffic to traverse unhindered through the access network. The described system and methods can be implemented in the application-layer and without any additional support from the network.

Abstract: According to a peer-to-peer protocol, a peer-to-peer network includes multiple clubs and multiple peers that receive content distributed by a source of the network. Each of the plurality of peers is part of at least two of the clubs. As content is generated, the source divides the content into multiple data blocks and assigns each data block to a club. Each data block is transmitted to peers that belong to the club assigned to the data block. When a peer in a club receives a data block assigned to that club, the peer distributes the data block to other peers in the club. Additionally, the peer transmits the data block to peers in other clubs. Also, the peer receives data blocks assigned to other clubs from peers that are not members of the club.

Abstract: Classification and verification of static file transfer protocols is provided. A network node sitting in the path of packets classifies traffic according to its content, and then statistically verifies that the content actually matches the initial classification. Classification and verification are standard building blocks in networks systems that provide quality-of-service. However, unlike traditional quality-of-service building blocks, a system of the present invention takes a trust-but-verify approach, and thus can rely on longer-timescale statistical online or offline verification to reduce computational requirements. This improves scalability and reduces the cost and complexity that in part has prevented prior service differentiation systems from succeeding in the Internet. Internet Service Providers (ISPs) can combine the classification and verification building blocks with a networked directory service to allow further classification as to whether particular content is for pay.
