“…Regarding traffic engineering and load balancing performances, works [114] and [162] provide analytical models to capture the performance of energy-aware network devices, especially those compliant with ACPI standard, that include LPI and AR techniques. As well as, they trade off energy consumption devices for packet forwarding.…”

“…As well as, they trade off energy consumption devices for packet forwarding. Moreover, the optimisation policies presented in [162] focus on the packet processing with respect to the overall device consumption, and able to find the best way to distribute traffic among the packet processing engine's pipelines. As the traffic matrices are considered independent, this algorithm can find different sets of link weights in the optimisation technique for each traffic matrix.…”

“…Good trade-off between these two potential opposing concerns is required. An analytical model in [114,169] allows the impact of power-saving techniques (such as adaptive link and low power idle techniques) on the quality of service metrics to be characterized, as well as how they affect the overall system behavior. This model can initiate a large set of network switching architectures, technologies and components and is becoming an interesting estimation tool that can be effectively adopted inside optimisation techniques for the dynamic control of green networking equipment.…”

Summary-Energy consumption of large-scale networks has become a primary concern in a society increasingly dependent on information technology. Novel solutions that contribute to achieving energy savings in wired networks have been proposed to mitigate ongoing and alarming climate change and global warming. A detailed survey of relevant power-saving approaches in wired networks is presented here. We give a special focus on carrier-grade networks. At first we perform a comprehensive study of communication infrastructures regarding energy saving. Then, we highlight key issues to enable green networks, ranging from network design to network operation. After that, we present the major contributors to power consumption in wireline networks. Afterwards, we survey, classify, and compare the main energyaware methods and mechanisms that are the most appropriate for improving the energy efficiency of carrier-grade networks.

“…In run-to-completion (RTC) architecture [20], one core handles all the functions, and packets stay on the core until the end of all procedures. In most scenarios, PPAs are designed as pipelines with multiple stages [21]. Each stage performs certain instructions on incoming packets, and delivers the packets to the next stage.…”

SUMMARYCache affinity has been proved to have great impact on the performance of packet processing applications on multi-core platforms. Flow-based packet scheduling can make the best of data cache affinity with flow associated data and context structures. However, little work on packet scheduling algorithms has been conducted when it comes to instruction cache (I-Cache) affinity in modified pipelining (MPL) architecture for multi-core systems. In this paper, we propose a protocol-aware packet scheduling (PAPS) algorithm aiming at maximizing I-Cache affinity at protocol dependent stages in MPL architecture for multi-protocol processing (MPP) scenario. The characteristics of applications in MPL are analyzed and a mapping model is introduced to illustrate the procedure of MPP. Besides, a stage processing time model for MPL is presented based on the analysis of multi-core cache hierarchy. PAPS is a kind of flowbased packet scheduling algorithm and it schedules flows in consideration of both application-level protocol of flows and load balancing. Experiments demonstrate that PAPS outperforms the Round Robin algorithm and the HRW-based (HRW) algorithm for MPP applications. In particular, PAPS can eliminate all I-Cache misses at protocol dependent stage and reduce the average CPU cycle consumption per packet by more than 10% in comparison with HRW.

“…The power cost brought by hardware devices such as network devices and servers in data centers accounts for a dominant part of the operational costs of data centers (Xu et al, 2013). Both industry and academia have been striving to improve energy efficiency of networking (Bolla et al, 2014) and eventually to realize the so-called energyproportional networking: i.e., the energy consumption is proportional to utilization of network interfaces (Nedevschi et al, 2008).…”
