PTX10008 System Overview

 

PTX10008 Hardware Overview

The Juniper Networks PTX10000 line of Packet Transport Routers bring physical and virtual innovations to the service provider core network. These next-generation routers help network operators achieve their business goals while effectively handling current and future traffic demands. For more information, see the following topics:



System Overview

The PTX10008 router provides 3.0 terabits per second (Tbps) per slot fabric capacity for service providers and cloud operators. The PTX10008 router for the core supports the PTX10K-LC1101, PTX10K-LC1102, PTX10K-LC1104, and PTX10K-LC1105 line cards.

The PTX10008 router provides an opportunity for the cloud and data center operators for a smooth transition from 10-Gigabit Ethernet and 40-Gigabit networks to 100-Gigabit Ethernet high-performance networks. This high-performance, 13 rack unit (13 U) modular chassis can provide 24 Tbps of throughput and 16 Bpps of forwarding capacity. The PTX10008 router has eight slots for the line cards that can support a maximum of 1152 10-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, or 240 100-Gigabit Ethernet ports.

The PTX10008 router can be deployed in the core as a label-switching router (LSR).

The PTX10008 (IP core) router is available in both base and redundant configurations for both AC and DC operation. All systems feature front-to-back airflow. This airflow is also know as airflow out (AFO).

Benefits of the PTX10008 Router

  • System capacity—The PTX10008 Packet Transport Router has a 13-U form factor and supports 24 Tbps per chassis or 72 Tbps per standard 19-in. telecommunications rack, with support for up to 240 100-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, or 1152 10-Gigabit Ethernet ports in a single chassis.

  • Full-scale IP and MPLS routing—PTX10008 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 PTX10008 provides additional flexibility per packet source. It has features such as 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.

  • Always-on infrastructure base—The PTX10008 is engineered with full hardware redundancy for cooling, power, switch fabric, and host subsystems. The Routing and Control Boards (RCBs) allow service providers to meet stringent service-level agreements across the core.

  • Nondisruptive software upgrades—The Junos operating system (Junos OS) on the PTX10008 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 PTX10008 router is 13 U tall. Up to three PTX10008 routers can fit in a standard 42-U rack with adequate cooling and power. All key PTX10008 router components are field-replaceable units (FRUs). Figure 1 illustrates the key components visible from the front of the chassis, Figure 2 illustrates the components that are visible from the rear of the chassis, and Figure 3 illustrates the components that are internal to the chassis.

Routing and Control Board

The Routing and Control board (RCB) (see Figure 4) contains a Routing Engine and is responsible for the system management and system control in the PTX10008. See PTX10000 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 configuration has a single RCB. The fully redundant configuration has two RCBs. The RCB also contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec) capable ports. See PTX10008 Components and Configurations.

Line Cards

The PTX10008 has eight horizontal line card slots and supports line rate for each line card. The line cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. PTX10008 line card architecture is based on a number of identical, independent Packet Forwarding Engine slices each with 500-Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line card slots labeled 0 through 7 (top to bottom) on the front of the chassis. All line cards are hot-removable and hot-insertable. After the hot insertion, you have to reboot the line card for the line card to be online.

Four line cards are available for the PTX10008 router:

  • PTX10K-LC1101, a 30-port 100-Gigabit or 40-Gigabit Ethernet QSFP28 line card. By default, the interfaces are created with 100-Gbps port speed. If you plug in a 40-Gigabit or 4x10 Gigabit transceiver, then you have to configure the appropriate port speed manually. Each of the 40-Gigabit ports can be configured as either a native 40-gigabit port or four 10-Gigabit ports using a breakout cable. With breakout cables, the line card supports a maximum of 120 logical 10-Gigabit Ethernet ports.

  • PTX10K-LC1102, a 36-port 40-Gigabit Ethernet line card that supports QSFP+ transceivers. Twelve out of the 36 ports on this line card also support the 100-gigabit QSFP28 transceivers . Each of the 40-Gigabit QSFP+ can be configured as either a native 40-Gigabit port or as four 10-Gigabit Ethernet ports by using a breakout cable. Thus, with breakout cables, the line card supports a maximum of 144 logical 10-Gigabit Ethernet ports.

  • PTX10K-LC1104, a 6-port coherent dense wavelength-division multiplexing (DWDM) with Media Access Control Security (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 QSFP28 line card that can be configured as 100-Gigabit Ethernet or 40-Gigabit Ethernet. The PTX10K-LC1105 line card supports MACsec security features.

  • QFX10000-60S-6Q—provides 60 small form-factor pluggable plus (SFP+) ports, that support 10-Gbps or 1-Gbps port speeds, 2 dual-speed QSFP28 ports that support either 40-Gbps or 100-Gbps port speed, and 4 QSFP+ ports that support 40-Gbps.

See Figure 5 for an example of a PTX10000 line card.

Switch Interface Boards

Five switch interface boards (SIBs) provide the necessary switching functionality to a PTX10008 router (see Figure 6). A sixth SIB is available in the redundant configuration to provide n+1 redundancy. SIBs are installed between the line cards and the fan trays inside the chassis . Each PTX10008 SIB has eight connectors that match to a line card slot, eliminating the need for a backplane. See PTX10008 Switch Interface Board Description.

Cooling System

The cooling system in a PTX10008 router consists of two hot-removable and hot-insertable FRU fan trays (see Figure 7) and two fan tray controllers (see Figure 8).

Two fan tray models and their associated fan tray controllers are available. Both models of fan tray contain 11 fans. The fan trays install vertically on the rear of the chassis and provide front to back chassis cooling. For model differences, see PTX10008 Cooling System and Airflow.

Power Supplies

Power supplies for the PTX10008 router are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each PTX10008 router with a base configuration has three power supplies; redundant configurations hold a maximum of six AC, high-voltage alternating current (HVAC), DC, or high-voltage direct current (HVDC) power supplies. Each power supply has an internal fan for cooling. See Figure 9 through Figure 12 .

Caution

Do not mix power supply models in the same chassis in a running environment. DC and HVDC can coexist in the same chassis during the hot swap of DC for HVDC.

PTX10008 Component Redundancy

The PTX10008 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 PTX10008 router can have one or two RCBs. When two RCBs are installed, one functions as the master and the other functions as the backup. If the master RCB (or either of its components) fails, the backup can take over as the master. See PTX10000 Routing and Control Board Description.

  • Switch Interface Boards (SIBs)—The PTX10008 routers have six SIB slots. 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 PTX10008 Switch Interface Board Description.

  • Power supplies—The PTX10000 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 PTX10000 router indefinitely.

    The PTX10000 router also supports source redundancy. Two sets of lugs are provided for the JNP10K-PWR-AC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each 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 PTX10008 Cooling System and Airflow.
