1. Juniper JUNOS software architecture
The Juniper JUNOS software architecture is a modular and scalable architecture that provides a high-performance, secure, and flexible platform for building and operating network devices such as routers and switches.
The JUNOS software architecture consists of several main components, including the following:
1. Kernel: The JUNOS kernel is the core of the operating system and provides low-level services such as process and memory management, device management, and network stack support.
2. Routing Engine (RE): The Routing Engine is responsible for the control plane functions of the JUNOS software, including routing protocol processing, firewall filtering, policy enforcement, and other control-plane functions.
3. Forwarding Engine (FE): The Forwarding Engine is responsible for the data plane functions of the JUNOS software, including packet forwarding, Quality of Service (QoS), and other data-plane functions.
