PTX10016 System Overview

The Juniper Networks PTX10016 Packet Transport Routers bring innovations in the physical and virtual environments to the service provider core network. These next-generation routers help network operators achieve their business goals. The routers effectively handle current traffic demands and are scalable for future traffic demands.

PTX10016 Packet Transport Router Description

PTX10016 routers provide cloud and data center operators with the highest levels of scale and throughput. PTX10016 is a next-generation modular router that offers ultra-high system capacity in a 21 U platform. It provides 230.4 Tbps per chassis. The PTX10016 has 16 slots for line cards that allow for a smooth transition from 10GbE, 40GbE, and 100GbE networks to 400GbE high-performance networks.

Figure 1: PTX10016 Packet Transport Router PTX10016 Packet Transport Router

You can deploy the PTX10016 in various network designs and fabrics, including:

  • Label-switched core routing

  • IP core

  • Peering

The PTX10016 routers come with either JNP10016-SF Switch Interface Boards (SIBs) or JNP10016-SF3 SIBs. If your PTX10016 has JNP10016-SF SIBs, it will come preinstalled with Junos® operating system (Junos OS). If your PTX10016 has JNP10016-SF3 SIBs, it will come preinstalled with Junos OS Evolved.

The PTX10016 is available in base and redundant configurations for operation with both AC and DC inputs. All configurations support front-to-back airflow, which is also known as airflow out (AFO).

Here is a brief overview of the PTX10016 router:

Benefits of the PTX10016 Router

  • System capacity—The PTX10016 has a 21-RU form factor and provides 230.4 Tbps per chassis.

  • Full-scale IP and MPLS routing—The PTX10016 delivers the distributed peering scale of 2.9 million forwarding information bases (FIBs) and 30 million routing information bases (RIBs) (also known as forwarding tables, and routing tables, respectively), 3000 OSPF adjacencies, and 4000 BGP sessions that are required to match expanding traffic demands.

  • Source Packet Routing in Networking (SPRING)—SPRING on the PTX10016 provides additional flexibility per packet source. SPRING provides network path and node protection to support:

    • MPLS fast reroute (FRR) mechanisms.
    • Enhanced network programmability.
    • Operation, Administration, and Maintenance (OAM) functionality.
    • Simplified network signaling, load balancing, and traffic engineering functions.
  • Nondisruptive software upgrades—The Junos OS running on the PTX10016 supports high availability (HA) features such as graceful Routing Engine switchover (GRES) and nonstop active routing (NSR), providing software upgrades and changes without disrupting network traffic.

Chassis Description

The PTX10016 is 21-U tall. Two PTX10016 chassis can fit in a standard 42-U rack with adequate cooling and power. All key PTX10016 components are field-replaceable units (FRUs). Figure 2 illustrates the components visible from the front of the chassis, Figure 3 illustrates the components that are visible from the rear of the chassis, and Figure 4 illustrates the components that are internal to the chassis.

Routing and Control Board

The RCB (see Figure 5) contains a Routing Engine and is responsible for the system management and system control in the PTX10016. See PTX10016 Routing and Control Board Description. RCBs are FRUs that are installed in the front of the chassis in the slots labeled CB0 and CB1. The base configurations have a single RCB. The redundant configurations have two RCBs. Each RCB contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec) capable ports. See PTX10016 Components and Configurations.

Figure 5: PTX10016 Routing and Control Board PTX10016 Routing and Control Board

The PTX10016 supports the following RCB models:

  • JNP10K-RE0

  • JNP10K-RE1

  • JNP10K-RE1-LT

  • JNP10K-RE1-128G

Line Cards

The PTX10016 features 16 horizontal line card slots and supports a maximum line rate of 14.4 Tbps for each line card. The line cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. The line cards are FRUs that you can install in the line card slots labeled 0 through 15 (top to bottom) on the front of the router chassis.

The PTX10016 with JNP10016-SF SIBs installed in it supports the following line cards:

  • PTX10K-LC1101, a 30-port 100GbE or 40GbE quad small form-factor 28 (QSFP28) line card. By default, the interfaces are created with 100-Gbps speed. Using the CLI, you can set up the interface to run at 40 Gbps. You can use the interface as either a native 40-Gbps interface or four independent 10-Gbps interfaces using a breakout cable. With breakout cables, the line card supports a maximum of 96 logical 10-Gbps interfaces.

  • PTX10K-LC1102, a 36-port 40GbE line card that supports quad small form-factor plus (QSFP+) transceivers. Twelve out of the 36 ports on this line card also support the 100GbE QSFP28 transceivers. You can configure each of the QSFP+ ports as either a native 40-Gbps interface or channelize the port as four 10-Gbps interfaces by using a breakout cable. When you channelize the 40GbE port, the line card supports a maximum of 144 logical 10-Gbps interfaces.

  • PTX10K-LC1104, a 6-port coherent dense wavelength-division multiplexing (DWDM) line card with MACsec. The line card features built-in optics that support flexible rate modulation at 100-Gbps, 150-Gbps, and 200-Gbps speeds.

  • PTX10K-LC1105, a 30-port flexible configuration line card that supports QSFP+, QSFP28, QSFP28-DD, QSFP56, and QSFP-DD transceivers. You can configure the line card either as 100GbE interfaces or as 40GbE interfaces. The line card also supports MACsec security features.

The PTX10016 with JNP10016-SF3 SIBs installed in it supports the following line cards:

  • PTX10K-LC1201-36CD, a 36-port line card that has 36 QSFP56-DD ports that support 400-Gbps speed. You can channelize the ports to operate at 200-Gbps, 100-Gbps, 50-Gbps, 25-Gbps, or 10-Gbps speeds by using breakout cables.

  • PTX10K-LC1202-36MR, a 36-port line card that has 32 QSFP28 ports that support 100-Gbps speed and 4 QSFP56-DD ports that support 400-Gbps speed.

See Figure 6 for an example of a PTX10016 line card.

Switch Interface Boards

Switch Interface Boards (SIBs) create the switch fabric for the PTX10016 router. The PTX10016 supports two models of SIBs:

  • The JNP10016-SF SIB supports Junos OS and has a switching capacity of 14.4 Tbps in one direction.
  • The JNP10016-SF3 SIB supports Junos OS Evolved Release 21.2R2 and later, and has a forwarding capacity of 45.9 Tbps in one direction.

You must install the SIBs between the line cards and the fan trays inside the chassis. Each SIB has 16 connectors that match to a line card slot, eliminating the need for a backplane. When six JNP10016-SF SIBs are installed, the PTX10016 has a routing capacity of 96 Tbps. When six JNP10016-SF3 SIBs are installed, the PTX10016 has a routing capacity of 565 Tbps. See PTX10016 Switch Interface Board Description.

Figure 7: JNP10016-SF SIB JNP10016-SF SIB
Figure 8: JNP10016-SF3 SIB JNP10016-SF3 SIB

Each SIB model has a set of unique connectors to mate the line cards and the RCB to the switch fabric. Some system components are also designed to operate with a specific switch fabric. See Table 1 for the components that each switch fabric supports.

Power Supplies

The PTX10016 routers support AC, DC, high-voltage alternating current (HVAC), and high-voltage direct current (HVDC) by offering the following power supplies:

  • JNP10K-PWR-AC

  • JNP10K-PWR-AC2

  • JNP10K–PWR-DC

  • JNP10K-PWR-DC2

Power supplies for the PTX10016 router are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each PTX10016 base configuration has five power supplies; redundant configurations hold the maximum of ten AC, HVAC, DC, or HVDC power supplies. Each power supply has an internal fan for cooling. You can install the power supplies in any slot. See Table 2 and Figure 13 through Figure 16.

PTX10016 Component Redundancy

The PTX10016 router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components in the redundant configuration provide redundancy:

  • Routing and Control Board (RCB)—The RCB consolidates the Routing Engine function with control plane function in a single unit. The PTX10016 routers can have one or two RCBs. When you install two RCBs, one functions as the primary and the other functions as the backup. If the primary RCB (or either of its components) fails, the backup can take over as the primary. See PTX10016 Routing and Control Board Description.

  • Switch Interface Boards (SIBs)—The PTX10016 routers have six SIB slots. In configurations that support JNP10016-SF SIBs, five SIBs are required for base operation, and the sixth SIB provides n+1 redundancy. All six SIBs are active and can sustain full throughput rate. The fabric plane can tolerate one SIB failure without any loss of performance. See the PTX10016 Switch Interface Board Description. You must not mix the two types of SIBs in the same chassis.

  • Power supplies—The PTX10016 routers require three power supplies for minimum operation (two RCBs, two fan trays, six SIBs, and no line cards). Additional power supplies provide n+1 redundancy for the system. AC, DC, HVAC, and HVDC systems tolerate a single power supply to fail without system interruption. If one power supply fails in a fully redundant system, the other power supplies can provide full power to the PTX10016 indefinitely.

    The PTX10016 routers also support power source redundancy. Two sets of lugs are provided for the JNP10K-PWR-DC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each JNP10K-PWR-AC and JNP10K-PWR-AC2 power supply.

  • Cooling system—The fan trays have redundant fans, which are controlled by the fan tray controller. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely. See PTX10016 Cooling System and Airflow.
