Introduction

Juniper Networks Contrail Service Orchestration (CSO) transforms traditional branch networks, offering opportunities for high flexibility of the network, rapid introduction of new services, automation of network administration, and cost savings. The solution supports both Juniper Networks and third-party virtualized network functions (VNFs) that network providers use to create network services.

CSO Release 4.1.0 is a secure software-defined WAN (SD-WAN) solution that builds on the existing capabilities of CSO and the Cloud CPE solution. The following are the highlights of the features available in Release 4.1.0:

CSO can be implemented by service providers to offer network services to their customers or by Enterprise IT departments in a campus and branch environment. In these release notes, service providers and Enterprise IT departments are called service providers, and the consumers of their services are called customers.

The solution offers the following deployment models:

CSO can be deployed in three deployment types—small, medium, or large. Table 1 shows the number of sites and VNFs supported for each environment.
