TL;DR: This work proposes an aggregation scheme that makes it possible to reduce power consumption and packet processing loads caused by a huge amount of short packets and focuses on the wide area Internet with this proposed scheme to support IoT traffic more efficiently.
Abstract: Internet of Things (IoT) is now considered as a key driving force for achieving next generation social systems. Several approaches have been proposed to achieve effective IoT communications, where each device has very limited communication capabilities. One such approach is the introduction of short packets for a lightweight communication protocol by which we can form a local area sensor network dedicated to IoT devices and can achieve effective packet processing, reducing power consumption, and minimizing bandwidth occupancy. The short packet can solve problems regarding local networks but creates another problem for the wide area Internet, where various devices and local networks are converged. We propose an aggregation scheme that makes it possible to reduce power consumption and packet processing loads caused by a huge amount of short packets. We focus on the wide area Internet with our proposed scheme to support IoT traffic more efficiently.

TL;DR: Programmable switches have attracted significant attention from both the research community and the industry, permitting operators and programmers in general to run customized packet processing functions as discussed by the authors, paving the way for an unprecedented wave of innovation and experimentation by reducing the time of designing, testing, and adopting new protocols; enabling a customized, top-down approach to develop network applications; providing granular visibility of packet events defined by the programmer; reducing complexity and enhancing resource utilization of programmable switches; and drastically improving the performance of applications that are offloaded to the data plane.
Abstract: Traditionally, the data plane has been designed with fixed functions to forward packets using a small set of protocols This closed-design paradigm has limited the capability of the switches to proprietary implementations which are hard-coded by vendors, inducing a lengthy, costly, and inflexible process Recently, data plane programmability has attracted significant attention from both the research community and the industry, permitting operators and programmers in general to run customized packet processing functions This open-design paradigm is paving the way for an unprecedented wave of innovation and experimentation by reducing the time of designing, testing, and adopting new protocols; enabling a customized, top-down approach to develop network applications; providing granular visibility of packet events defined by the programmer; reducing complexity and enhancing resource utilization of the programmable switches; and drastically improving the performance of applications that are offloaded to the data plane Despite the impressive advantages of programmable data plane switches and their importance in modern networks, the literature has been missing a comprehensive survey To this end, this paper provides a background encompassing an overview of the evolution of networks from legacy to programmable, describing the essentials of programmable switches, and summarizing their advantages over Software-defined Networking (SDN) and legacy devices The paper then presents a unique, comprehensive taxonomy of applications developed with P4 language; surveying, classifying, and analyzing more than 200 articles; discussing challenges and considerations; and presenting future perspectives and open research issues

TL;DR: Novel approaches that utilize the header manipulations of the P4 (Programming Protocol-Independent Packet Processor) switches to aggregate small IoT packets into a large one, transmit it over a network, and then disaggregate it back to the original small packets, all in the data plane of the hardware P4 switch.
