nfv architecture

Editor's note: This article is following the Service-aware network architecture based on SDN,NFV For further analysis of DPI , the three deployment scenarios that may occur in SDN are analyzed, and the 4-7 The business requirements of the tier and the business-aware network architecture are described in depth. 650) this.width=650; "src=" http://s3.51cto.com/w

Does the NFV service require big data, small data, or both ?, Both nfv and nfv Operating NFV-based services and networks is the next service focus of progressive communication service providers (CSPs). However, it is not easy to achieve this goal. In fact, CSP indicates that it takes a lot of time and effort to build

After completing this course, you will be able to: Describe the basic concepts of NFV Understand the development trend of NFV network technology Understanding the NFV Architecture Describe the relationship between NFV and SDN Understand the key capab

network elements must be far beyond the deployment scale of control network elements. The cost of NFVI is closely related to the IT infrastructure scale, server shipments directly affect the purchase price. Therefore, the economic benefit of NFV depends on large-scale deployment. Only after the virtual deployment of forwarding network elements can NFV be implemented on a large scale. From this point of vie

absorbed by NFVO. The concept of a network service disappears or is absorbed into a wider range of service concepts. The VNF we are familiar with is further divided into fine-grained network functions in the management system architecture. Operators need to figure out when and where standards are needed, and manufacturers are thriving in differentiation. Operators need to take advantage of the advantages of standardization while ensuring service

functions. The challenge here is whether the general x86 hardware server platform can meet the capability, reliability, and latency requirements of dedicated hardware, which are very important to telecom operators. Here, I would like to praise Intel, the other end of the industry chain, because over the past 20 years, Intel has been constantly improving its chip processing capabilities and enriching its chip features. Taking DPDK as an example, this technology solves the forwarding capability i

that NFV and SDN will be used to support different RAN and different business types running on these RAN. In addition, the commercial introduction of SDN and NFV is expected to grow significantly over the next few years, so that network Slicing can provide flexible network installation to meet the needs of various applications and services. In addition, SDN can be used to provide an overall

to have multiple cores, better memory bandwidth and efficiency, and a range of performance options. As a result, ONP has become a solid foundation for future continuous predictable system performance improvements. § Virtualization (for example, compute and IO) optimizations can improve the efficient use of existing and future server platforms. § regular improvements in microarchitecture and instruction sets can improve network load performance. § Reliable compute platform support enables the

is postponed due to incomplete implementation of NFV specifications. Distributed architecture creates uncertainty in the responsibility of vendors to identify and resolve network problems. Therefore, the most cautious part of a distributed architecture is the head of network operations. Communication service providers are also facing huge organizational chan

At this time of 14, we also debated whether NFV was OpenStack in the OpenStack community. Now the controversy has been resolved. OpenStack has become an important part of the NFV discussion, as reflected in the ETSI Mano Conceptual architecture diagram below, OpenStack is the primary performer of the Virtualization Infrastructure Management (VIM) layer. OPNFV is

NFV has the potential to help operators strengthen network security, but NFV is a double-edged sword that also creates new security risks while strengthening security. The panel discussed the issue at the NFV everywhere workshop held last week.Admittedly, network function virtualization (NFV) can indeed help network op

officials say it is good for the industry and Opendaylight, though they will face some challenges in the short term. Note: ONOS is made by on. Lab uses Java and Apache to deliver the first open Source SDN network operating system, primarily for service providers and Enterprise backbones. Onos is designed to meet the needs of the network to achieve high reliability, good performance and flexibility. In addition, Onos's north-to-interface abstraction layer and API support simple application devel

Each successful NFV must have an NFVI supporting it. NFV's biggest advantage is its virtualization network function, which can fundamentally change the delivery methods of services and applications. However, behind these features, there must be a network function virtualization infrastructure (NFVI) that supports it, and this technology is not yet clearly defined. Many vendors claim that they can provide NFVI, but there is a big difference between th

Editor's note: With the deep development of cloud computing,SDN and NFV have been on the ground in the world with cloud-like concepts, and have a certain scale of application in enterprise network and telecom network, but standardized, Security issues are becoming more prominent. The "NetEvents2015 Global Cloud Computing Innovation Summit" was held in San Francisco, USA, and the summit gathered all aspects of the cloud computing industry chain, includ
