    We received the following question!

    Can I see network topology with Paragon?

    Yes, Network topology acquisition is implemented using BGP-LS or OSPF/ISIS which advertise node and link attributes such as IP addresses, link color, maximum bandwidth, reservable bandwidth, unreserved bandwidth by priority, metric, TE metric, Adj. SID and label , Router ids, ABR/ASBR flag, attached bit flag, overload flag, hostname, area ID, Spring capabilities.

    LSP information is also collected using PCEP (Path Computation Element Protocol)

    Can I use Telemetry and SNMP for collection traffic information?

    yes,  Paragon Insights accepts data from various types of telemetry sensors and from traditional network management protocols like syslog and SNMP. 

    Data can be collected following two models: the traditional 'pull' data-gathering model where data is requested from network devices periodically, at a user-defined interval and the push' data-gathering mode which is now the preferred method, where devices send or push data to the collector regularly.

    Within this push model Paragon supports NetFlow, OpenConfig, Syslog which can report RPM test results, SNMP, netflow, and Junipers own propiertary GBP model.  These are referred to as Junipers Telemetry Interface (JTI)

    Within this push model Paragon supports CLI/NETCONF (referred to as iAgent, and SNMP.

    Absolutely, Paragon Insights can capture log information from network elements of interest, parse it like an expert system and create alerts, and run ML analytics on numeric data (anomaly detection/outlier detection/prediction).

    Our next question we received is:

    We are operating NorthStar and HealthBot products today, will the GUI for Paragon Pathfinder, Planner and Insights be the same or updated?

    Also, for HealthBot and NorthStar, can I still run the applications in standalone installs after upgrading to Paragon?

    Great questions! We have integrated the products under a common and fresh UI. You should find all what you need if you have been a previous NorthStar or HealthBot user easily.  And yes, you can still run the products standalone, but it will be much easier and more convenient if you operate them from a common runtime.

    Yes, Anuta ATOM is part of the Paragon Automation Portfolio and we are driving integration with ATOM and the other Paragon components as an equal citizen. It does however retain its name as it is a partner product.

    Hi Experts!

    I was wondering, what is the difference between Pathfinder and Planner?

    Thanks in advance!

    Pathfinder uses real time data from BGP-LS and PCEP, Planner on the other hand uses snapshots of the network. With Pathfinder you can make changes in the actual network, like modifying the path of LSPs, or provision new LSPs.  In Planer you can simulate all kinds of situations like a node failure, link failure, traffic demands increases, and so on, without affecting the actual user traffic. Planner is basically a sandbox. You can have multiple network models in Planner to test different things. In Pathfinder there is only one network model, the one: the network model that is live and carrying real user traffic

    In addition, Pathfinder can export snapshots of the currently deployed topology and statistics into Planner, so one can work of fresh data to do the planning and simulation. A perfect pair to have.

    Thanks Experts! I have another question for you.

    What are the differences between using a JVM and using cRPD in NorthStar? Does Paragon have the JVM option?

    JVM runs in a virtual machine and can communicate with the topology server via NTAD (Network Topology Abstractor) or BMP. cRPD - Containerized routing protocol daemon  is Juniper's routing protocol daemon (rpd) decoupled from Junos OS and packaged as a Docker container to run in Linux-based environments. cRPD has a smaller footprint, is faster, and more scalable.  The current NS controller supports both options, in Paragon the JVM will no longer be an option.

    Also, the JVM supports both NTAD and BMP while cRPD only suports BMP.

    The JVM receives BGP-LS updates and forwards this topology data into to the Toposerver using (NTAD), which is a server daemon that runs in the JunosVM.

    BGP Monitoring Protocol (BMP) can be used as an alternative to NTAD. BMP runs automatically when you install NorthStar, thought is not used unless you configure NorthStar and the JVM.   BMP is standard based, and only supports BGP topology acquisition. It is the recommended method running on cRPD.

    The NTAD process on junosVM is actually end of life and will eventually be not supported. Another reason to  chose cRPD.

    We received the following question:


    How is Paragon Active Assurance different to using ICMP Pings?

    While ICMP Ping is a useful application to verify that there is connectivity between one IP host and another, Paragon Active Assurance is a complete solution for both testing and real-time monitoring of data plane KPIs unavailable with Ping. This includes UDP metrics for one-way delay and jitter, packet reordering, packet loss, and multicast performance -- with support for TWAMP (RFC5357). For TCP, the solution measures stateful TCP throughput and efficiency (based on RFC6349). For services, metrics include HTTP and DNS response times, HTTP throughput, voice MOS quality, multicast performance, and HTTP streaming video quality.

    While ICMP is limited to sending 5 packets per second (for non-root users), Paragon Active Assurance can generate active synthetic traffic and measure one-way jitter down to tens of nanoseconds using hardware time-stamping features of Intel NICs.

    Also, all automation capabilities and metrics in Paragon Active Assurance are exposed through NETCONF or REST APIs of the controller, which can be either SaaS or on-premises.

    So our active assurance solution is much more than just basic ICMP Pings. I hope that explains.

    What are my options for installing NorthStar? Would they change with Paragon?

    In NorthStar, there are 4 different options using bare metal or virtual machines. 

    JVM will not be an option in Paragon, so the only options is to use cRPD in a container. Other components will also be implemented using containers. The NTAD process on junosVM is end of life.

    yes, we will honor preexisting valid Northstar and Healthbot licences and convert them to Paragon licences so you can upgrade.

    Paragon Pathfinder, Planner and Insights are on-prem / on-site software at present. Paragon Active Assurance is offered as on-prem and as well as a SAAS / Cloud product.

    Within Paragon Pathfinder you can see link and LSP related data for latency, not jitter.  Paragon Active Assurance gives you the ability to measure end-to-end or do network segment measurements at high fidelity for latency,  jitter and packet loss.
