Multi-access Edge Computing (MEC) is a type of network architecture that provides cloud computing capabilities at the edge of the network. We consider the use case of video surveillance for an university campus running on a 5G-MEC environment. A key issue is the eventual overloading of computing resources on the MEC nodes during peak demand. We propose a new strategy for distributed orchestration in MEC environments based on how load balancing strategies organize processing queue. Then, we elaborated a strategy for deadline-aware queueing prioritization that organizes requests based on pre-established thresholds. We introduce a simulation-based experimentation environment and conduct a number of tests demonstrating the benefit of our approach by reducing the number of referrals and improving the effectiveness in meeting deadlines.

Load-balanced Service Function Chaining in Edge Computing over FiWi Access Networks for Internet of Things
服务功能链(SFC)有望为物联网(IoT)实现灵活且可扩展的虚拟网络基础设施。边缘计算被认为是处理大量物联网应用数据的有效解决方案。为了在分布式边缘计算节点(ECN)之间统一为物联网应用提供服务,提出了一种基于SDN和NFV协调的统一SFC编排框架,该框架通过利用FiWi接入网络的连接性提供协同边缘云平台。此外,我们研究的VNF部署问题在我们的协同框架下,我们制定了一个混合整数非线性规划(MINLP)问题,共同考虑负载均衡的网络和计算链VNF。我们还提出了两个近似的最优部署算法贪婪二分多路径(GBMP)和KSP多路径(KSMP)利用部署在ECN的多实例虚拟网络功能(VNF)和FiWi接入网络的多路径能力。在两种类型的物联网应用场景中进行了广泛的仿真,在EC over FiWi接入网络。数值结果表明,在两种典型场景下,我们提出的算法在负载均衡、业务接受率和网络利用率方面均优于单路径和基于ECMP的部署算法.
