“…Notice that SSPF-R finds that cable deletions in the sequence from ((9, 6), 2) to ((4, 5), 1) in Q are optimal and thus, the Best_Q equals Q. For ((4, 6), 1), Step 2 sets n 46 =1+1=2, and argmax in Step 3 selects (0, 3), which affect P 3 =((0, 3), (3,6)) that was generated in SSPF-1. Thus, GH-Flow() generates a new path P 3 =((0, 1), (1,4), (4,6)) that has sufficient capacity to route demand 3.…”

Efficient heuristics for energy-aware routing in networks with bundled links

Abstract-Current networks are typically over-provisioned to ensure low delays, redundancy and reliability. These Quality of Service (QoS) guarantees are typically achieved using high end, high power network equipments. Their use, however, has led to concerns regarding green house gas emissions, which garnered a lot of attention recently and have resulted in a number of global initiatives aim at reducing the carbon footprint of Internet Service Providers (ISPs). These initiatives have motivated ISPs and researchers to design novel network algorithms and hardware that scale the usage or active time of a network according to traffic load. To this end, this paper considers the problem of shutting down a subset of bundled links during off-peak periods in order to minimize energy expenditure. Unfortunately, identifying the cables that minimize this objective is an NP-complete problem. Henceforth, we propose several practical heuristics based on Dijkstra's algorithm and Yen's k-shortest paths algorithm.We evaluated our heuristics on the Abilene network -with both real and synthetic traffic matrices and several larger random topologies with various loads. Our results show that the proposed heuristics to be effective and efficient. Moreover, our approaches could potentially reduce the energy usage of cables used in the Abilene network by up to 56.7%, assuming the traffic demands recorded on September 5, 2004.

Abstract-Internet infrastructure energy consumption is a major topic of research nowadays due to environmental and economical concerns. Therefore, it is increasingly important new solutions that decrease energy consumption, but without impairing network throughput and costs. Hence, it is important to survey and categorize current techniques, not only applicable to IP networks, but that can also be potentially useful for the future Internet architectures, such as Publish-Subscribe architectures. Therefore, to achieve such goals this paper presents a survey on energy efficient architectures and functional mechanisms (such as energy adaptive routing) for the current and future Internet. The main goals are: to provide an overview of the issues of the current Internet architecture; to identify the contribution of the different proposals for the future Internet architecture; and to discuss energy saving techniques which improve Internet energy efficiency.Index Terms-Energy, future internet architectures, energy efficient routing, traffic engineering, survey.

Greening the NetFPGA Reference Router

Abstract:Energy efficiency is an important criterion in the design of next generation networks for both economic and environmental concerns. This paper presents an energy-efficient router that is able to dynamically adapt its routing capability in response to real-time traffic load, achieving energy proportional routing. The NetFPGA reference router, which operates at one of two frequencies (125 MHz or 62.5 MHz), requires a board reset to switch frequencies. We have modified the reference router to allow dynamic switching among five operating frequencies. Experiments with real traces indicate that, compared to the reference router, a 10% power reduction can be achieved through dynamic frequency scaling. When the router is further modified to support green traffic engineering and Ethernet port shut-down, power consumption can be reduced by 46% while maintaining the required quality of service. This allows the router to meet the instantaneous performance requirements while minimizing power dissipation. Similar results can be expected when these general power-saving principles are applied in future commercial routers.
