“…Middle Net uses DPDK for high-performance, zero-copy packet delivery in L2/L3 NFV [15]. The sleep-based approach proposed by Wu not only reduces the high not-used power waste and high CPU usage caused by DPDK's empty polling but also reduces the negative impact of DPDK's high CPU usage on other services [16].…”

“…However, when the data flow increases and the receiving and forwarding capacity is limited, the continued increase in the buffer length will cause issues such as memory overflow and wasted system resources, which affect data processing. Considering this problem, a dynamic multicore multi-cycle buffer model was designed to enhance the data processing receiving and forwarding capacity while vertically expanding the buffer to ensure that data can be received within the processing cycle and simultaneously forwarded to other nodes in time for processing and storage [6,7,16,19,31].…”

“…The forwarding core queries the forwarding table and forwards the prepared data according to the configuration table information. After completing data forwarding, the memory space is released and the forwarding table is updated simultaneously [6,7,16].…”

“…The data link layer between the Media Access Control Address (MAC) sublayer and the physical layer is implemented as a functional module, which provides the MAC sublayer with the same invocation interface as the physical layer, and the aggregated link is a physical interface for the MAC sublayer. Therefore, when the MAC sublayer forwards data, it only needs to send the data to be forwarded to the link aggregation functional module through the logical port provided by the link aggregation [7,16].…”

Concurrent access to large-scale video data streams in edge computing is an important application scenario that currently faces a high cost of network access equipment and high data packet loss rate. To solve this problem, a low-cost link aggregation video stream data concurrent transmission method is proposed. Data Plane Development Kit (DPDK) technology supports the concurrent receiving and forwarding function of multiple Network Interface Cards (NICs). The Q-learning data stream scheduling model is proposed to solve the load scheduling of multiple queues of multiple NICs. The Central Processing Unit (CPU) transmission processing unit was dynamically selected by data stream classification, as well as a reward function, to achieve the dynamic load balancing of data stream transmission. The experiments conducted demonstrate that this method expands the bandwidth by 3.6 times over the benchmark scheme for a single network port, and reduces the average CPU load ratio by 18%. Compared to the UDP and DPDK schemes, it lowers the average system latency by 21%, reduces the data transmission packet loss rate by 0.48%, and improves the overall system transmission throughput. This transmission optimization scheme can be applied in data centers and edge computing clusters to improve the communication performance of big data processing.

Environmental concerns and the impact of technology on climate change are now a global concern. To this effect, reducing CO 2 emission is one of the factors that has been the focus of researchers, activists, and governments. This has been included in the UN's 2030 Agenda for Sustainable Development. The emissions produced due to running software have remained largely unquantified or neglected in Carbon Accounting. This paper proposes "CO 2 Emission Efficiency" as a measurable Non-Functional requirement. We propose a framework for estimating software's CO 2 emissions and compare two well-known databases, Apache Cassandra and Aerospike. The paper presents the method, process, and comparisons. The paper then considers the costs of each of these technologies and concludes that reducing CO 2 emissions not only has a positive impact on the environment but can also be cheaper and reduce costs.
