“…Indeed, we proposed that each ISP offers a service to the P2P users which explicitly helps them to choose "good" neighbors by ranking possible peers [4,3]. Such traffic localization mechanism for P2P traffic, as proposed by Aggarwal et al [4,3], Xie et al [36], Choffnes and Bustamante [11], are currently under discussion within the IETF ALTO [32] working group.…”

Content delivery systems constitute a major portion of today's Internet traffic. While they are a good source of revenue for Internet Service Providers (ISPs), the huge volume of content delivery traffic also poses a significant burden and traffic engineering challenge for the ISP. The difficulty is due to the immense volume of transfers, while the traffic engineering challenge stems from the fact that most content delivery systems themselves utilize a distributed infrastructure. They perform their own traffic flow optimization and realize this using the DNS system. While content delivery systems may, to some extent, consider the user's performance within their optimization criteria, they currently have no incentive to consider any of the ISP's constraints. As a consequence, the ISP has "lost control" over a major part of its traffic. To overcome this impairment, we propose a solution where the ISP offers a Provideraided Distance Information System (PaDIS). PaDIS uses information available only to the ISP to rank any client-host pair based on distance information, such as delay, bandwidth or number of hops.In this paper we show that the applicability of the system is significant. More than 70% of the HTTP traffic of a major European ISP can be accessed via multiple different locations. Moreover, we show that deploying PaDIS is not only beneficial to ISPs, but also to users. Experiments with different content providers show that improvements in download times of up to a factor of four are possible. Furthermore, we describe a high performance implementation of PaDIS and show how it can be deployed within an ISP.

“…For example, experimenting with P2P technology the authors in [116] noticed that downloading times of files in a locality-aware P2P system may decrease up to 20%. Aggarwal et al in [14] reported decrease up to 30%. Increase in the average downloading rate up to 80% have been observed in [87].…”

“…For example, Comcast recently reported that around 34% of P2P traffic was localized in their filed trials [87]. Another evidence is due to Aggrawal et al who demonstrated that the amount of localized traffic in P2P systems can be increased from 10% to 60%-80% [14].…”

“…Nowadays, traffic localization in P2P systems is mainly considered as a way to decrease ISP expenses limiting the amount traffic which is sent over backbone and inter-ISP links (see [14,54] among others). Although traffic localization techniques were originally proposed for file sharing systems, they can also be beneficial for streaming content.…”

“…In [15], the authors extended their oracle service proposing an Internet-wide global coordinate systems based on cooperation between ISPs. Elaborating this approach further in [14], they suggested to obtain not only geographical locations but bandwidth of the end users too. Making this information available to new peers that join a network will allow for proper choice of peering nodes in the system.…”

UARA in edge routers: an effective approach to user fairness and traffic shaping

SUMMARY The ever‐increasing share of the peer‐to‐peer (P2P) traffic flowing in the Internet has unleashed new challenges to the quality of service provisioning. Striving to accommodate the rise of P2P traffic or to curb its growth has led to many schemes being proposed: P2P caches, P2P filters, ALTO mechanisms and re‐ECN. In this paper, we propose a scheme named ‘UARA:textbfUser/Application‐aware RED‐based AQM’ which has a better perspective on the problem: UARA is proposed to be implemented at the edge routers providing real‐time near‐end‐user traffic shaping and congestion avoidance. UARA closes the loopholes exploited by the P2P traffic by bringing under control the P2P users who open and use numerous simultaneous connections. In congestion times, UARA monitors the flows of each user and caps the bandwidth used by ‘power users’ which leads to the fair usage of network resources. While doing so, UARA also prioritizes the real‐time traffic of each user, further enhancing the average user quality of experience (QoE). UARA hence centralizes three important functionalities at the edge routers: (1) congestion avoidance; (2) providing user fairness; (3) prioritizing real‐time traffic. The simulation results indicate that average user QoE is significantly improved in congestion times with UARA at the edge routers. Copyright © 2011 John Wiley & Sons, Ltd.
