“…In [Shi et al 2009], to tackle the same problem, it is presented RACC (Receiver Assistant Congestion Control mechanism), a TCP congestion control mechanism that combines loss-based and delay-based features. [Li et al 2021] proposes Sphinx, a novel transport protocol alternative to TCP that addresses the problem of throughput performance in mobile High Speed Lossy Networks, i.e., mobility is also taken into consideration. In a sense, we consider that our work is complementary to such efforts because regardless of the scheme employed in the Transport Layer, the chosen routes will allow higher throughput to the individual TCP sub-flows (e.g., for DVPTCP, with TCPBP, a lower number of subflows may be sufficient to obtain the same throughput of DVPTCP with routes computed with traditional metrics).…”

In this work, we present Transmission Control Protocol Best Path (TCPBP), an alternative link-state routing metric aims to optimize single-path TCP throughput on intradomain High Speed Lossy Networks. The enhanced performance is achieved by combining delay and packet loss on a single mixed metric as a function parameter. In contrast, this function predicts the TCP throughput that should be maximized. As proof of concept, TCP bandwidth tests were executed in an SDN High Speed Lossy Network Linux-emulated topology with ten nodes, employing an intradomain link-state routing protocol (i.e., OSPF-like) capable of running both TCPBP and traditional metrics delay and hop-count. Such topology was chosen because of the potential to improve its TCP throughput with route selection, given the characteristics of the topology itself and the TCP throughput prediction model adopted. The overall TCP throughput performance obtained with TCPBP was greater than with different routes founded by traditional metrics, showing the potential of our proposal.

“…There are several options for ingress controllers. We experiment with Nginx ingress controller 7 and Traefik ingress controller 8 , and opt for Traefik due to better performance. Kubeless leverages Kubernetes HPA for auto-scaling and does not support scaleto-zero.…”

“…Nuclio, being relatively more CPU hungry, is able to scale more rapidly (in 40s) than Knative and OpenFaaS. For Kubeless, the fork-per-request and no queuing of function pods result in high latency and packet loss, which in turn contributes to lower throughput and lower CPU utilization [7]. Thus it leads to poor auto-scaling performance.…”

Serverless computing is increasingly popular because of its lower cost and easier deployment. Several cloud service providers (CSPs) offer serverless computing on their public clouds, but it may bring the vendor lock-in risk. To avoid this limitation, many open-source serverless platforms come out to allow developers to freely deploy and manage functions on self-hosted clouds. However, building effective functions requires much expertise and thorough comprehension of platform frameworks and features that affect performance. It is a challenge for a service developer to differentiate and select the appropriate serverless platform for different demands and scenarios. Thus, we elaborate the frameworks and event processing models of four popular open-source serverless platforms and identify their salient idiosyncrasies. We analyze the root causes of performance differences between different service exporting and auto-scaling modes on those platforms. Further, we provide several insights for future work, such as auto-scaling and metric collection.
