Cross-Cluster Networking to Support Extended Reality Services
arxiv(2024)
摘要
Extented Reality (XR) refers to a class of contemporary services that are
intertwined with a plethora of rather demanding Quality of Service (QoS) and
functional requirements. Despite Kubernetes being the de-facto standard in
terms of deploying and managing contemporary containerized microservices, it
lacks adequate support for cross-cluster networking, hindering
service-to-service communication across diverse cloud domains. Although there
are tools that may be leveraged alongside Kubernetes in order to establish
multi-cluster deployments, each one of them comes with its drawbacks and
limitations. The purpose of this article is to explore the various potential
technologies that may facilitate multi-cluster deployments and to propose how
they may be leveraged to provide a cross-cluster connectivity solution that
caters to the intricacies of XR services. The proposed solution is based on the
use of two open source frameworks, namely Cluster API for multi-cluster
management, and Liqo for multi-cluster interconnectivity. The efficiency of
this approach is evaluated in the context of two experiments. This work is the
first attempt at proposing a solution for supporting multi-cluster deployments
in a manner that is aligned with the requirements of XR services
