specific technology. It is a network design concept. It plans the software, hardware, forwarding plane and control plane of the network and the interaction between them, the network architecture is redefined and divided into forwarding layer, control layer, business orchestration layer, and application layer. We often say that SDN controller refers to the control layer software that sends a stream table to

supports this strategy by making software and hardware improvements to the entire data center network portfolio. In addition, brocade has strengthened its commitment to open software management, Orchestration and SDN controller plans by providing new technologies that support the OpenDaylight Project and OpenStack. The OpenDaylight Project and OpenStack Project are strategic open-source software projects d

NFV white Paper, and proposed the NFV objectives and action plan, which aims to decouple the software and hardware of traditional telecommunications equipment, based on common computing, Storage and networking devices enable telecom network functions, improve management and maintenance efficiency, and enhance system flexibility.After more than 3 years of development, NFV technology has become increasingly mature, into the rapid development period, standards organizations, open source organizati

communication and workload flow between multiple clouds are maintained, is extremely important. Only in this way can disaster recovery and high availability be ensured. If you want to create a hybrid cloud environment to deploy your workloads and transfer the workload securely between public and private clouds, you need to learn from Google, A way to convert virtual identifiers within a single data center is designed. There are many such examples. For example, because VPN (Virtual Private Netwo

, log off, and move a virtual machine at any time, depending on the load. This rigid demand is a product of VMware's range of products, as well as the orchestration systems represented by OpenStack and Cloudstack. But these systems are only managing servers, and the physical network is irrelevant to them. When a virtual machine is migrated from one host to another, the physical network sometimes has to be adjusted accordingly (such as reconfiguring th

allows the network to view and respond to traffic and dynamic adjustments, such as "Denial of Service Attack" (DDOS) or elephant stream, and implement it automatically. Any service of the physical or virtual network they have created can be controlled in a fully programmable manner by an SDN controller. They can standardize YANG and NetConf data modules and use REST APIs to mix and match suppliers in their networks. However, networks are only an impo

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 capabilities of NFV Traditional carrier networks evolve to NFV Study Questions and retrieval What is NFVThe definition from Huawei: NFV, Network function virtualization (Fu

NFV needs to be commercially available on several fronts When talking about networks, there are two words that cannot be bypassed at all, namely SDN and NFV. SDN emphasizes the separation of forwarding and control. By introducing a new control plane, it shields details of forwarding plane from different manufacturers and realizes intelligent and centralized network control functions; NFV emphasizes the dec

, especially in the public cloud environment, how does the PAAs service access the container? A: We are now public cloud PAAs per user is a virtual machine, the virtual machine internal communication using the default network mode overlay, in the case of large concurrency is not obvious. Q: Are containers bare metal deployment, container orchestration, and scheduling tools? A: Our private cloud products are bare-metal deployments,

The red part is the custom Logic Abstraction section, which can be summed up into the following microservices in terms of functional responsibilities (described in more detail later): Authentication Resource Management Application Orchestration Elastic Scaling Log Collection Monito

Not long ago a PhD student and blogger who studied Sdn complained: "Now the Open Source SDN controller performance is poor Ah, 2K a new stream per second will prompt packet-in too much, stop working." The blogger asked how he defined a stream, which he said with TCP 5 tuple. The blogger asked him how he produced such dense packet-in, he said, using a server to send packet-in directly to the

software focusing on NFV than cloud. At present, less than half of the vendors that claim to be able to provide NFVI have their own orchestrations. Most vendors rely on customers to find the integrated orchestrator themselves. Role of OPNFV in NFVI Development With VIM and the orchestration tool, the open source platform (OPNFV) of the open source project NFV can play a role first. To correctly define VIM-related interfaces, OPNFV must define what NF

About routing service in OpenFlow Network (1) Here, the so-called OpenFlow network refers to a set of OpenFlow switches connected to each other, and all these switches are placed under the management of an OpenFlow Controller or an OpenFlow Controller cluster. The routing service of OpenFlow network refers to simply sending a Packet from one Host to another, rather than implementing layer-3 IP routing protocol. The host is also the destination of the route. It can be a physical server or Virtu

It may be easy to think that the word "Cloud" is always illusory for technical clusters. However, the benefits of large-scale virtualization and other plans are visible, such as network convergence, greater economies of scale, and concentrated resources. These changes provide a new way of working and the colle

Io, it can create a virtual network to connect docker containers deployed on multiple hosts. All the containers via weave are like being connected to the same network switch. The applications using the network do not need to configure port ing and links. External devices can access the services provided by application containers on the weave network, and existing inter

ABSTRACT The security and dependability of the SDN is still an open issue. Argue for the need to build secure and dependable sdns by design. First Step:describe Several threat vectors that may enable the exploit of SDN vulnerabilities. Then:sketch the design of a secure and dependable SDN control platform as a materialization of the concept.

, and it is difficult to implement on ordinary commercial products, which is a difficult solution for most designers who want to adopt the Clos architecture. Perhaps with the development of SDN technology such as OpenFlow, more progress can be made in this area. Juniper Qfabric To some extent, also similar to a centralized control and scheduling of Clos network architecture, many of the details of the design is not disclosed, the actual use of the eff

Tags: OpenStack network open source Neutron Virtual SwitchNow, when it comes to virtual switches, it's common to think of using open vswitch as a virtual switch because both individuals and businesses that support open vswitch want an open model to integrate their services into OpenStack. The open Vswitch community has done a lot of work to improve the position of open vswitch as the primary virtual switch. The community expects open vswitch to provide all the best possible switching services wh
