Q
What is the throughput capacity of the Juniper PTX1000 router?
A
The Juniper PTX1000 delivers up to 2 Tbps of full-duplex forwarding capacity, supporting high-density 100G and 400G interfaces for scalable edge and aggregation deployments.
Q
How does the PTX3000 differ from the PTX1000 in performance and scale?
A
The PTX3000 offers up to 6 Tbps of forwarding capacity—three times that of the PTX1000—while maintaining the same compact form factor, ideal for medium-scale core and peering applications.
Q
What are the key scalability features of the PTX5000 router?
A
The PTX5000 supports up to 32 Tbps of forwarding capacity, modular slot design, and up to 80 line-card slots for flexible port density and future growth.
Q
Which use cases are best suited for the Juniper PTX10000 series?
A
The PTX10000 series is optimized for large-scale IP/MPLS core networks, high-performance peering, and massive data center interconnects requiring over 100 Tbps of aggregated throughput.
Q
Do Juniper PTX series routers support 400G interfaces?
A
Yes, PTX1000, PTX3000, PTX5000, and PTX10000 platforms support pluggable 400G QSFP-DD and CFP2-ACO optics, enabling ultra-high-speed connectivity for demanding applications.
Q
What software architecture do Juniper PTX routers use?
A
All PTX models run the carrier-grade Junos OS with separated control and packet forwarding planes, ensuring high reliability, programmability, and feature consistency across the portfolio.
Q
How does Junos OS enhance performance on PTX routers?
A
Junos OS leverages the Trio chipset’s deep buffering and deterministic packet processing, delivering sub-50-microsecond latency and zero packet loss under full load.
Q
What redundancy and high-availability features are available on PTX platforms?
A
PTX routers support dual Routing Engines, redundant power supplies and fans, nonstop software upgrade (NSSU), and hitless SR-IOV failover for uninterrupted service.
Q
How can I automate and manage Juniper PTX routers?
A
PTX routers integrate with Juniper Apstra for intent-based network automation, support native REST APIs, NETCONF, and Ansible modules for seamless orchestration.
Q
What is the typical power consumption per line-card slot in the PTX series?
A
PTX line cards consume between 200W and 600W per slot, depending on port density and optics, with efficient power-scaling features to minimize operating costs.
Q
Which licensing model applies to Juniper PTX1000/3000/5000/10000 routers?
A
Juniper offers a base software feature set with optional licensed feature bundles—such as advanced MPLS, segment routing, and timing services—on a perpetual or subscription basis.
Q
How do PTX routers address ultra-large routing table scale?
A
Powered by the Trio chipset and dedicated route processing, PTX platforms support up to 2 million IPv4/IPv6 routes, ensuring high-scale Internet peering and backbone services.
Q
What built-in security features protect Juniper PTX routers?
A
PTX routers include control-plane policing, MACsec encryption on line cards, co-located threat intelligence, and RPKI validation for robust network security.
Q
What is the return on investment when deploying Juniper PTX series routers?
A
Juniper PTX reduces CAPEX by consolidating multiple tiers, lowers OPEX with efficient power and cooling, and accelerates service rollout to maximize ROI within 12–18 months.
Q
How can I integrate PTX routers into my existing network fabric?
A
PTX platforms support seamless interoperability with any IP/MPLS network, Barco-based DC fabrics, and industry-standard APIs, enabling smooth migration and hybrid cloud connectivity.
Q
What support and warranty options are available for Juniper PTX series?
A
Juniper offers a one-year hardware warranty, optional Juniper Care with 24x7 support and advanced replacement, and premium support tiers for rapid issue resolution.
