In the last decade, companies and organizations have rapidly been adopting network virtualization (NV) in an effort to take advantage of the flexibility offered by software-based computing and storage resources. With software-defined networking (SDN) and network functions virtualization (NFV) promoting decoupling of the control and forwarding planes, more emphasis has been put on NV as of late. For example, Juniper Networks network virtualization is created by the company’s switches, routers, orchestration, and management tools working together to offer an open and automated SDN solution.
How Does Juniper Networks Network Virtualization Work?
Network virtualization for Juniper helps an array of organizations, from service providers and enterprises, to emerging cloud companies. Juniper SDN integrates with orchestration software and results in automation of the entire infrastructure across compute, storage, and the network, enabling applications and services the ability to be set up, as well as scaled up or down on command.
Integrated with OpenStack as a foundation orchestration technology through Contrail for overlay network control, and Junos Space Network Director for orchestration of network management capabilities, Juniper SDN can also connect to third-party orchestration systems with the help of REST APIs. Together, these elements deliver a common platform for physical and virtual orchestration management. Also partnering with VMware to bring NSX Controller capabilities to some of its routing and switching products, Juniper’s aim is to provide users with a broader range of SDN Controller options and features.
The Juniper Networks network virtualization solution also provides network services such as load balancing, WAN optimization, content caching, deep packet inspection (DPI), and security services such as firewalls, distributed denial of service (DDoS) protection, and SSL VPN, to name a few. The forwarding plane can be physical (such as MX Series, EX Series, QFX Series, or PTX Series platforms) or virtual (Contrail vRouter, vMX), and implemented in hardware or software, depending on its location in the network, or on performance and scalability demands.
Benefits of Juniper Networks Network Virtualization
There are several advantages to using Juniper Networks network virtualization. With a solution that covers multiple use cases and several network domains, no “rip and replace” of existing infrastructure is necessary. This allows users to embrace SDN and network virtualization without forgoing past networking investments. Juniper Networks network virtualization also helps users avoid expensive vendor lock-in by using an open architecture that interoperates with a large array of networking and service options, both physical and virtual, either in hardware or software, and brought to you by Juniper or another company. Juniper Networks network virtualization also provides intelligent automation by giving users the power to simplify operations and decrease OpEx with a policy-driven framework.
Based on scale-out distributed software that has high availability, Juniper Networks network virtualization is always-on and elastic. It is also Network Equipment Building System (NEBS)-compliant for service provider deployments in various situations. Better security is integrated with cloud platforms provides perimeter- and hypervisor-level security that leverages open source for transparency.
