“…The TQS protocol is suited for a network topology with dynamic nodes, such as RLN, as it is inspired by MPLS. MPLS was released by Cisco System in 1998 and started to gain popularity in IP deployment for wide area networks (WAN) and metropolitan area networks (MAN) [18], [19] in 2000. MPLS allows tunnel routing known as label switched paths (LSP), where a tunnel is characterized by a path in the network and by a reserved bandwidth [20], [21].…”

This paper presents a model and an analysis of the Tag QoS switching (TQS) protocol proposed for heterogeneous robots operating in different environments. Collaborative control is topic that is widely discussed in multirobot task allocation (MRTA) -an area which includes establishing network communication between each of the connected robots. Therefore, this research focuses on classifying, prioritizing and analyzing performance of the robot local network (RLN) model which comprises a point-to-point topology network between robot peers (nodes) in the air, on land, and under water. The proposed TQS protocol was inspired by multiprotocol label switching (MPLS), achieving a quality of service (QoS) where swapping and labeling operations involving the data packet header were applied. The OMNET++ discrete event simulator was used to analyze the percentage of losses, average access delay, and throughput of the transmitted data in different classes of service (CoS), in a line of transmission between underwater and land environments. The results show that inferior data transmission performance has the lowest priority with low bitrates and extremely high data packet loss rates when the network traffic was busy. On the other hand, simulation results for the highest CoS data forwarding show that its performance was not affected by different data transmission rates characterizing different mediums and environments.

“…At the same time, a few high‐speed router products as fast as ATM switches were developed to satisfy the demands from the market. In the beginning of 2000 and with the existence of MPLS, research and development on the switching protocol has narrowed down to implementing and improving MPLS, as it is an IP‐based system; IP is a common protocol for wide area network and metropolitan area network …”

Summary This paper presents the modeling and analysis of a proposed label–quality of service (QoS) switching protocol for heterogeneous robot in a swarm. Establishing the data communication and network in multirobot task allocation is an important aspect in robot collaboration. Instead of passing the data through the cloud network, each robot can be configured as a node in its swarm for intercommunication. This research was conducted to model and propose aggregation and classification methods in a swarm robot network inspired from multiprotocol label switching, namely, label‐QoS switching protocol. Each packet of data is forwarded with a proposed 2‐side label values that are concerned with addressing and QoS. This proposed protocol was applied in each of the node's routing, and it was set up with forwarding information table. The simulation and analysis were conducted in 2 situations: (1) with a constant n–label switch mobile robot and a number of packet data increasing with time and (2) with a constant number of packet and varying n–label switch mobile robot by time. With reference to the network parameter performances, it shows that the anomaly treatment by the proposed protocol is able to prioritize the data forwarding between the robots at the edge of the swarm with class of service although the robot community at the center is increasing or getting crowded.

“…In this issue, Doshi et al, in "Future WAN Architecture Driven by Services, Traffic Volume, and Technology Trends," 6 show that the traffic growth and technology scalability considerations will lead to flatter networks with the intelligent optical core supporting multiservice edges and that the WAN transport layer will migrate from SONET/SDH rings to multiwavelength optical meshes with flexible restoration capability selectable per wavelength path. The paper also discusses economic benefits of this architecture and its ability to generate new revenues through rapid creation of services.…”
