Juniper Networks and the Network Automation Market

About 80% of network failures are due to human errors, according to the 2021 “Network Automation Market Report.” For delivering top experiences, network automation is essential. Companies cannot depend on manual or semi-automated network management, as the risk of network failure is increasingly high. Besides, as the traffic patterns change frequently, they also require real-time configuration changes.

Other associated issues are: failed service deliveries; costly outages; lengthy repairs; and delayed service activation.

Implementing network automation can address these issues and promise faster, more agile, and more efficient service delivery at optimized costs. It also raises IT productivity by standardizing processes and streamlining network changes.

As a result, more organizations are turning to network automation solutions. The 2022 “Network Automation Statistics” says that by 2027, the global network automation market size will reach $22.58 billion.

In the sector, Juniper Networks has been developing solutions for transforming network experiences to maximize user efficiency and operational performance. These efforts have, for instance, led Juniper Networks to be named a leader in the Gartner “Magic Quadrant” for indoor location services in 2022.

Paragon Pathfinder Features

Paragon Pathfinder is a software-defined networking (SDN) controller that helps businesses to orchestrate network functions for flawless operations, acting as an interface between the network infrastructure and the organization. It uses a centralized control pane for improved network management. MPLS/RSVP capabilities, network slicing, or segment routing can be implemented for mapping traffic flows onto an existing physical topology.

Segment routing is an effective solution to simplify traffic engineering and management across diverse network domains, as it relies on a source-based routing architecture that can remove state information from network nodes and transit routers. As a result, the network design gets simplified.

Paragon Pathfinder also helps centralize path communication for effective network implementation and operations. It can identify potential issues associated with the network and receive real-time performance monitoring through Junos Telemetry Interface. It then streams data to a performance management system to measure link and node utilization trends. It can also troubleshoot network congestion issues.

Its other key features also include:

  • Provides network optimization with path computation algorithms
  • Offers an intelligent interface between SR-enabled networks and RSVP-TE networks
  • Addresses multilayer optimization
  • Plans maintenance events for rerouting traffic
  • Provides detailed insights, like node status, link utilization, segment routing paths, and label-switched paths (LSPs), through live network topology maps
  • Helps with real-time monitoring of IP/MPLS paths along with provision segment routing
  • Offers solutions for complex interdomain path-computation

Key Benefits of Paragon Pathfinder
