Junos Node Slicing Overview

Junos node slicing enables service providers and large enterprises to create a network infrastructure that consolidates multiple routing functions into a single physical device. It helps leverage the benefits of virtualization without compromising on performance. In particular, Junos node slicing enables the convergence of multiple services on a single physical infrastructure while avoiding the operational complexity involved. It provides operational, functional, and administrative separation of functions on a single physical infrastructure that enables the network to implement the same virtualization principles the compute industry has been using for years.

Using Junos node slicing, you can create multiple partitions of a single physical MX Series router. Each partition behaves as an independent router, with its own dedicated control plane, data plane, and management plane. This enables you to run multiple services on a single converged MX Series router, while still maintaining operational isolation between them. You can leverage the same physical device to create parallel partitions that do not share the control plane or the forwarding plane, but only share the same chassis, space, and power.

Junos node slicing supports new deployment models that do not have all components physically located on the in-chassis Routing Engine but still maintain the operational experience of a traditional Junos OS system.

With Junos node slicing, you can achieve network convergence—both horizontal and vertical. Horizontal convergence consolidates router functions of the same layer to a single router, while vertical convergence collapses router functions of different layers into a single router. In both the cases, operational and functional separation is achieved through physical convergence on the same chassis.
