The Virtual Network must be open.

As virtual networks become increasingly complex, users cannot rely on end-to-end solutions provided by a vendor to meet service agility and scalability requirements. Brocade vyatta provides an open platform for cloud and telecom operators to regain control over the network.

In the journey towards the software network, brocade (brocade) has ushered in a new turning point-the release of the brocade vyatta platform. The Brocade vyatta platform is an open and modular software network platform for cloud service providers and telecom operators. Its release clarifies that the brocade software network is characterized by "Openness". It also shows that, building an open software network platform will lead brocade in the next 5 ~ The overall program of development over the past 10 years will be centered on brocade's investment and technological innovation.

　　Flexible Deployment of software networks

The Brocade vyatta platform meets the requirements of etsi nfv isg, including network function Virtualization (NFV) and software defined network (SDN) technologies based on open standards and open source plans. The Brocade vyatta platform uses mature core components, including brocade vyatta vrouter and brocade vadx, as well as open-source software projects related to opendaylight and openstack.

Liu Weicheng, director of the business and strategic business relationship department of the North Asia operator of brocade Corporation, said that the architecture of the brocade vyatta platform includes three core layers: NFV Connection Service, SDN structure service, and function orchestration. Each layer of this open platform is modular. You can select a suitable module as needed to build a data center network.

Specifically, the NFV connection service layer uses brocade vyatta vrouter, brocade vadx, and service products including third-party elements to deploy 3rd ~ Layer-7 network functions. The SDN architecture service layer relies on the rapid development of opendaylight projects involving many vendors. It implements centralized control through SDN and simplifies the network. The function orchestration layer manages the entire network architecture by introducing a wide range of functions of openstack and third-party configuration and software orchestration layers that are interoperable. Liu Weicheng said: "The most important feature of the brocade vyatta platform is openness. All products and services that comply with opendaylight, openstack standards, and frameworks can access brocade's open software network platform ."

Many telecom operators in Europe and the United States are already deploying NFV because it can quickly respond to business needs, quickly build network functions, and simplify data center operations, it allows telecom operators to get more revenue by quickly launching new services.

　　Faster NFV implementation

SDN and NFV constitute two important parts of the software network. According to the current situation, NFV is faster than Sdn. Liu Weicheng shares the same feeling: "NFV is only a function and does not need a complete system like Sdn. When deploying NFV, you do not need to implement Sdn. If SDN is not deployed, you can also directly introduce the NFV function to the existing network. This is what many large cloud service providers do. NFV does not have to be mixed with openstack ."

NFV is a software-based network function that must be previously implemented using dedicated hardware. NFV includes functions such as virtual routers and virtual firewalls. SDN and NFV are two different concepts. SDN is a network control platform, and NFV is a network virtualization function that can immediately replace physical routers and switches. A software network only needs one controller, but there may be a large number of NFV. Therefore, the growth of NFV is larger than that of Sdn. The technical standards of SDN are still unknown, which also creates some obstacles for the launch of SDN-related products. The main feature of the NFV ecosystem created by brocade is openness. Software networks must be built on open and standard hardware platforms.

　　Openness is the most important

Brocade provides an open and modular architecture in terms of software networks. If you want to transition from a traditional network to a software network, brocade can provide a complete set of solutions, including connection services, structural services, and feature orchestration. If you have already deployed SDN, then, brocade can only provide other modules that constitute the software network, such as NFV or software orchestration module. Liu Weicheng stressed that brocade can provide users with flexible modules in terms of software networks.

In addition to actively switching to the software network market, IT vendors such as VMware and HP are also involved in SDN and NFV. Brocade's software network platform supports a variety of virtual machines and connects virtual network functions with different hypervisor to give users more choices. For example, the brocade vyatta system supports five types of virtual machines, including VMWare, Microsoft, and open-source virtualization software.

"We need to leverage our expertise in IP network technology on the basis of virtual machines. Our company has just hired 120 engineers. Their main job is to better achieve the virtualization of physical network devices through independent R & D or joint development, add more network virtualization functions to the open software network platform." Said Liu Weicheng.
