Multi-access Edge Computing (MEC) is gaining momentum as it considered one of the enablers 5G ultra-Reliable Low-Latency Communications (uRLLC) services. MEC deploys computation resources close to end user, enabling reduce drastically end-to-end latency. ETSI has recently leveraged architecture run all entities, including applications, Virtual Network Functions (VNF) in a Virtualization (NFV) environment. This evolution allows taking advantage mature and tools NFV, potential apply variety...
Internet Service Providers are becoming more involved in the audiovisual content delivery chain. One manifestation of this trend is emergence telco CDNs, i.e., networks operated by telecom service providers. In work, we make case for opening CDN infrastructure to providers means network function virtualization (NFV) and cloud technologies. We design implement a CDN-as-a-Service architecture, where can lease resources on demand at regions ISP has presence. Using open northbound RESTful APIs,...
We present the design and implementation of a content-delivery-network-as-a-service (CDNaaS) architecture, which allows telecom operator to open up its cloud infrastructure for content providers deploy virtual delivery network (CDN) instances on demand, at regions where has presence. Using northbound REST APIs, can express performance requirements demand specifications, are translated an appropriate service placement underlying substrate. Our architecture is extensible, supporting various...
We address the fundamental tradeoff between deployment cost and service availability in context of on-demand content delivery provision over a telecom operator's network functions virtualization infrastructure. In particular, given specific set preferences constraints with respect to cost, computing resource capacity, we provide polynomial-time heuristics for problem jointly deriving an appropriate assignment resources virtual instances placement latter subset available physical hosts....
We focus on the provision of Content-Delivery-Network-as-a- Service (CDNaaS) functionality for video distribution and, in particular, how to appropriately decide amount computing resources allocate a CDNaaS instance satisfy Quality Experience (QoE) and resource capacity constraints. Our work is put context telco cloud environment, which open content providers request dynamic deployment virtual CDN infrastructure top it, cover target user demand with desired service quality at regions where...
We focus on the problem of optimal compute resource allocation and placement for provision a virtualized Content Delivery Network (CDN) service over telecom operator's Functions Virtualization (NFV) infrastructure. Starting from Quality Experience (QoE)-driven decision necessary amount CPU resources to allocate satisfy virtual CDN deployment request with QoE guarantees, we address distributing these machines placing latter physical hosts, optimizing conflicting objectives management cost...
Nowadays, 4G services are evolving towards the fifth generation (5G) cloud native ones. In particular, Mobile Network Operators (MNOs) need to integrate and test multiple components from orchestration infrastructure level, including applications terminals. These perspectives imply reducing Operational Expenditures injecting automation in MNOs' mobile network infrastructure. From this perspective, we present paper an integrated networking system based on Open Source Software (OSS). As part of...
We present in this paper the 5G EVE European project which aims at interconnecting multiple sites order to form a single end-to-end facility. Each partner of proposes solution elements that will host use-cases brought by verticals. In particular, we detail architecture French testbed includes four nodes different locations. also used technologies and how plan implement network slicing within 5G-EVE highlight some recommendations sharing our experience building federated testbed.
In this paper we present a 5G design and deployment framework within the 5G-EVE European project which aims at interconnecting multiple sites in order to form single end-to-end facility. Each partner of proposes solution elements that will host use-cases brought by verticals. Plug'in as allowing different partners verticals create test innovative components for 5G. We also how such VNFs are on-boarded finally give quick overview vertical's workflow.
