200 articles on TechPost
After three years of activity, we passed the 200 articles mark last month. Writers have been extremely prolific, let's try to build a page with links to all these posts with a short abstract.          
200 Articles on TechPost

Introduction

Juniper Networks, now HPE Juniper Networking, is, at its very foundation, a technological company. When we opened the TechPost platform with the motto "Byte-Sized Articles on Juniper Solutions by Network Engineers, for Network Engineers", we wanted to create a place where Juniper engineers could share their knowledge and experience on technologies, products and protocols with no marketing fluff.
Three years later, I'm proud of the result, we published the 200th TechPost article last month. And it's now becoming challenging to display a "tile" for each article on the home page.
This post lists the 205 articles published (in November 2025) with a short abstract, sorted in different categories.
Thanks to the 70+ writers who often took on their free time to share their knowledge, and thanks to you, the readers who provided useful feedback and encouragement during these years.

Traffic-Engineering (RSVP, SRTE)

  • Inter-domain On-demand SR-TE LSPs with BGP-LS (By Anton Elita)
  • SR Tactical Traffic Engineering in Junos (By Moshiko Nayman)
    • https://community.juniper.net/blogs/moshiko-nayman/2025/02/19/sr-tactical-traffic-engineering-in-junos
    • Junos OS 23.4R1 introduces Segment Routing Tactical Traffic Engineering (SR-TTE), a unique and innovative solution designed to address temporary network congestion by dynamically adjusting traffic flows in real-time, directly within the router. SR-TTE leverages existing mechanisms to alleviate congestion without requiring interoperability between different router vendors or with external controllers. 
  • SR-TE LSPs Through a Multi-Domain Network (By Ricardo Dominguez)
  • Wholistic Design Approach for MPLS Backbone Class of Service (By Kashif Nawaz)
  • Class Based Forwarding over RSVP LSPs Design Consideration (By Kashif Nawaz)
    • https://community.juniper.net/blogs/kashifnawaz1/2025/06/23/class-based-forwarding-over-rsvp-lsps-design
    • While Class of Service (CoS) ensures that priority traffic receives preferential treatment on congested interfaces, it does not inherently provide a mechanism to reduce transit latency for delay-sensitive traffic flows. Class-Based Forwarding (CBF) addresses this gap by enabling network operators to steer high-priority traffic over the shortest or most optimal paths, while directing low-priority traffic over longer or less optimal routes.
  • Adaptive Resource Control in TE Networks (By Kashif Nawaz)
    • https://community.juniper.net/blogs/kashifnawaz1/2025/07/02/adaptive-resource-control-in-te-networks
    • In modern MPLS networks, managing traffic flows with precision is essential for maintaining performance and reliability. RSVP-TE provides a robust framework for establishing traffic-engineered paths that align with specific resource requirements. As network conditions fluctuate, static bandwidth reservations often fall short. To address this, dynamic mechanisms like auto-bandwidth allow the network to adapt in real time, ensuring efficient use of available capacity.
  • Adaptive Resource Control with Container LSPs (By Kashif Nawaz)
    • https://community.juniper.net/blogs/kashifnawaz1/2025/07/21/adaptive-resource-control-with-container-lsps
    • Modern MPLS networks must support highly dynamic traffic patterns, especially in cloud and service provider environments. While RSVP-TE provides engineered path control, traditional single-LSP scaling is often insufficient. Auto-bandwidth helps, but as demand grows, deploying parallel LSPs across ECMP-eligible paths becomes essential. These parallel LSPs improve load distribution, enabling more scalable and resilient transport.

  • PTX and ACX7000 FIB Compression (By Nicolas Fevrier)
    • https://community.juniper.net/blogs/nicolas-fevrier/2022/09/19/ptx-fib-compression
    • How the PTX and ACX7000 routers running Junos EVO are currently implementing FIB compression. Principles and concrete real-life examples.
  • BGP RIB Sharding (By Ravindran Thangarajah)
    • https://community.juniper.net/blogs/ravindran-thangarajah/2022/10/24/bgp-rib-sharding
    • Principles of sharding for Multithreaded BGP (update threads, shards, …) and real-life examples, customer deployments.
  • Mastering BGP PIC on JUNOS (By Moshiko Nayman)
    • https://community.juniper.net/blogs/moshiko-nayman/2023/10/24/mastering-bgp-pic-on-junos
    • Optimizing Failover Convergence for Enhanced Network Resilience with BGP PIC implementation in JUNOS.
  • BGP FlowSpec “Exclude Interfaces” on Express2 Platforms (By Jordan Head)
    • https://community.juniper.net/blogs/jordan-head/2023/06/07/bgp-flowspec-exclude-interfaces-express2-platforms
    • BGP FlowSpec is one of the mechanisms that allows a network to protect itself against DDoS attacks. A common mitigation tactic is to redirect malicious traffic to a scrubbing center for further analysis. If any of the analyzed traffic is found to be legitimate, it can be re-injected into the network. However, we must make a few considerations to ensure the re-injected traffic is properly forwarded to its original destination.
  • Time Synchronization and Class D Clocks Support (By Rafik P)
    • https://community.juniper.net/blogs/rafik-p/2023/06/20/time-synchronization-and-class-d-clocks-support
    • Timing and synchronization requirements and capabilities are continually evolved to drive the ultra-low latency, mission critical and advanced radio applications for 5G and beyond. Satisfying the new enhanced ITU-T and other standards for time accuracy in network equipment requires careful planning of the timing architecture.
  • G.8275.1.enh: Juniper's Advancements in Timing and Synchronization (By Vladimir Moki)
