The Junos OS is a powerful network operating system that is widely used in Juniper Networks devices. It is designed to provide high availability, security, and scalability. Two key design goals of the Junos OS are:
Clean separation of control and forwarding planes: The Junos OS separates the control plane, which is responsible for managing the device's routing protocols and other services, from the forwarding plane, which is responsible for processing packets and forwarding them to their destination. This separation allows for better performance, scalability, and security. For example, if a problem occurs in the forwarding plane, the control plane can continue to operate without interruption, which ensures that the network remains stable and available. In addition, this separation also helps to prevent malicious attacks that target the control plane by isolating it from the forwarding plane.
Modularization of multiple software processes: Another design goal of the Junos OS is the modularization of multiple software processes. Each process performs a specific function, such as routing protocol management or interface management, and operates independently of the other processes. This modular design provides several benefits, including improved performance, better fault tolerance, and easier troubleshooting. For example, if a problem occurs in one process, it does not affect the operation of other processes, which ensures that the network remains stable and available. Additionally, the modular design also allows for the addition or removal of functionality without affecting the overall operation of the device.
While the Junos OS does support a variety of hardware platforms, it does not rely on a single hardware platform for all software applications. Instead, the Junos OS is designed to be hardware-agnostic, meaning it can run on a variety of devices, including routers, switches, and security appliances. This allows Juniper Networks to provide customers with a range of hardware options to choose from, based on their specific needs and requirements.
Finally, the Junos OS does provide a clean separation of security and routing policies, which is important for ensuring that security policies are enforced consistently across the network. However, this is not one of the two primary design goals of the Junos OS.
