Comparison of router testbeds: embedded system-based, software-based, and multiprotocol label switching (MPLS)

Abstract

<span>Multiprotocol Label Switching (MPLS) is a promising packet switching technology in the field of communication network, allowing router to forward the packets based on labels. However, off-the-shelves routers are made to be non-configurable, making it less suitable for academic research purposes. The aim of this paper is to explore the possibility of developing a configurable MPLS router by reviewing embedded system-based router, software-based router and commercial MPLS router itself. The architecture of the routers will be described in detail and their performances will be compared. From the analysis, we found that the development of reconfigurable MPLS router testbed is achievable by using embedded system-based hardware due to its freedom of reconfigurability.</span>

Performance Evaluation Reprogrammable Hybrid Fiber-Wireless Router Testbed for Educational Module

“…A testbed can also be reconfigured to different topologies as required. A review on two types of router testbeds (commercial-based and embedded systembased) were presented in [30]. The commercial-based are storebought off-the-shelf routers [31,32].…”

“…Some examples of embedded system-based routers are using netFPGA [33], Banana Pi [34] and Raspberry Pi [35][36][37]. From the study in [30], the embedded system-based routers are reconfigurable, reprogrammable, scalable and cost less than the commercial routers. These advantages will be a suitable choice for the lab-scale router testbed in research and academic field.…”
