PTX10003 System Overview

• Juniper Networks ExpressPlus™ Silicon: The PTX10003 is powered by our custom ExpressPlus silicon, providing predictable IP/MPLS packet performance and functionality, along with inline AES-256 MACsec encryption on all the ports. The MACsec encryption is supported up to 100 GbE line rate.

• Peering Scale: To match the expanding traffic demands, the The PTX10003 delivers a peering scale of up to 4 million Forwarding Information Base (FIB) routes and up to 60 million Routing Information Base (RIB) routes, also known as forwarding and routing tables, respectively.

• QSFP-DD: The PTX10003 supports universal multi-rate QSFP-DD optics, quadrupling aggregate switch bandwidth while maintaining port density. QSFP-DD supports continuing growth in network bandwidth demand and data center traffic. Systems designed with QSFP-DD are backwards compatible, allowing them to support existing QSFP optical modules and provide flexibility for end users and system designers.

• Juniper Networks Junos OS Evolved: The PTX10003 operates on Junos OS Evolved, Juniper Networks next-generation Junos OS. Junos OS Evolved has the same CLI user interface, the same code base for applications and features, and the same management and automation tools as Junos OS. However, the Junos OS Evolved infrastructure is entirely modernized, delivering the high availability, portability, faster innovation, and simplified upgrades you need.

• Interoperability: The PTX10003 provides seamless interoperability with existing Juniper routing deployments.

The PTX10003-160C scales to 16 Tbps in a single chassis. Operating in a fixed core router configuration, the PTX10003-160C has flexible interface configuration options, with universal multirate QSFP-DD for 100 GbE/400 GbE to support 320 (QSFP +) 10 GbE ports, 80 (QSFP +) 40 GbE ports, 160 (QSFP28) 100 GbE ports, 64 (QSFP28-DD) 200 GbE ports, or 32 (QSFP56-DD) 400 GbE ports. Refer to Figure 1.

Using Juniper Networks custom ExpressPlus silicon, the PTX10003 system architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the PTX10003 to achieve high performance.

Control operations are performed by the Routing Engine, which runs Junos OS Evolved. The Routing Engine handles routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Junos OS Evolved is pre-installed on the PTX10003 internal solid-state drives (SSDs).

Forwarding operations are performed by the Packet Forwarding Engines (PFE) on the ports at line rate. The PFE delivers inline MACsec on all the ports up to 100 GbE line rate.

The PTX10003 runs Junos OS Evolved, which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS Evolved runs natively on Linux, giving it direct access to all the Linux utilities and operations. It is designed to be modular, allowing for upgrades to be done on a component-by-component basis without a system reboot. Only those components changed are restarted. Junos OS Evolved is easily portable and minimal work is required to make it work on any platform. It has the same CLI user interface, the same code base for applications and features, and the same management and automation tools as Junos OS. However, the Junos OS Evolved infrastructure is entirely modernized, giving you the high availability, portability, faster innovation, and simplified upgrades you need. Junos OS Evolved software is installed on the PTX10003 200 GB internal NAND solid state flash drive.
