“…Gurbani et al [5] provide a good survey on existing solutions for the ALTO problem. ALTO solutions can be divided into two categories: (A) application-level techniques to estimate parameters of the underlying network topology and (B) layer cooperation.…”

Integration of application layer traffic optimization (ALTO) in software-defined mobile networks could have several benefits for orchestration of endpoint selection for distributed services. ALTO can provide guidance, e.g., in the redirection of end users to appropriate in-network cache, content distribution network server or virtual network function instance during service chaining. ALTO service provides appropriate level of abstraction of network and cost maps, enforcing the policies of mobile network operator and optionally other actors, but keeping the privacy of network topology information. SDN controllers can enforce flow redirection and can dynamically provide abstracted network and cost maps to ALTO server. In this paper we present the operation of ALTO in software-defined networks from the point of view of mobile network operators, and describe our proof-of-concept implementation.

“…Such that, delivering the SLA (Service Level Agreement) assured CDN flows (such as delay upper bound) can be difficult. One current solution is to integrate CDN with ALTO/P4P [19], so that the CDN can choose the best distributor for the users. However, the current approaches on ALTO still have the fundamental limitations: The network topology cannot be accurately estimated with ease from the application layer [19].…”

Programming a network for innovative services or for function improvements has never been easier using SoftwareDefined Networking (SDN). However, the programming tasks can also be significantly complicated by the asynchrony of data plane states and complexities of service control states. In order to reduce the complexity for programming a network service in Distributed Control Plane of SDN, we propose a proGRAmming Control (GRACE) layer as a generic solution, which provides two key features, namely, reconfigurability and reusability. Their implementations deal with aforementioned challenges, thus to achieve the consistency of the data plane states and the reusability of the service control states at the distributed controllers. This paper introduces the reconfigurability and reusability with their design goals and their impact on the programmability of DCP. We further use two popular network services, ICN (InformationCentric Networking) and CDN (Content Distribution Networks) to illustrate these concepts. NS-3 simulations and PlanetLab emulations are conducted to show the advantage of using the GRACE layer for ICN and CDN. Results show that the ICN Interest delay is reduced by 19.6% and CDN request delay is reduced by 81% in extremely harsh network conditions.

“…Recent developments in the IETF ALTO Working Group are summarized in [44]. Gurbani, Hilt et al also conduct a survey of research on the application-layer traffic optimization problem and the need for layer cooperation in [45], where the authors state that ALTO problem will be best achieved by enabling communications between the P2P application layer and the network layer. As a summary of Section 3, we compare P2P traffic management techniques discussed above in Table 3.…”

The flourish of P2P systems draws a lot of attention of networking researchers. Some research efforts focus on P2P systems, trying to understand the mechanism of various implementations and the behavior pattern of P2P users, and then improve the systems' performance. Others look at the issue from the angle of ISPs, trying to help ISPs solve various issues brought by P2P applications. In this article, we conduct a review study on recent research efforts in these two areas. The first part of this article focuses on several key strategies that have significant influence on the performance of P2P systems. In the second part, we review some important techniques for ISPs to manage P2P traffic, i.e., blocking, caching and localization, and compare their advantages and disadvantages.
