The QFX5100-24Q-AA Application Acceleration switch speeds the performance of critical time-sensitive applications by processing them within the network fabric using the QFX-PFA-4Q Packet Flow Accelerator (PFA) expansion module, which features a highperformance 320 Gbps fieldprogrammable gate array (FPGA) with 1 million logical elements. The unique combination of 320 Gbps PFAs and a 2.56 Tbps Packet Forwarding Engine (PFE), all powered by Juniper’s robust Junos operating system, makes the QFX5100-24Q-AA the most customizable switch in the industry.

Product Description

The Juniper Networks QFX5100-24Q-AA Application Acceleration switch is a compact, 1 U, high-density 40GbE data center switch. The base unit features 24 quad small formfactor pluggable plus transceiver (QSFP+) ports; with the addition of an optional QFXPFA-4Q Packet Flow Accelerator (PFA) expansion module, the switch can morph into an intelligent application acceleration system. Alternatively, the QFX5100-24Q-AA can expand to support 32 QSFP+ ports by installing two four-port 40GbE expansion modules; when scaled to 32 ports, the QFX5100-24Q-AA supports wire-speed performance with an aggregate throughput of 2.56 Tbps or 1.44 Bpps per switch.

QFX5100-24Q-AA software architecture.

To support application processing on the QFX5100-24Q-AA, the CPU subsystem is enhanced with a quad-core Intel CPU with 32 GB DRAM and additional storage capacity through an onboard 128 GB solid-state drive (SSD). The enhanced CPU provides dedicated resources for applications running in the guest virtual machines (VMs) on the switch and also enables greater flexibility for custom programming of the PFA module.

The QFX-PFA-4Q PFA is a four-port 40GbE expansion module for QFX5100-24Q-AA featuring an Altera Stratix V 320 Gbps FPGA with 1 million logical elements. The PFA supports 160 Gbps high-speed internal connectivity to the Packet Forwarding Engine (PFE) on the QFX5100-24Q-AA platform, while four front-panel QSFP+ ports enable direct external connections to the PFA subsystem.

The QFX5100-24Q-AA CPU subsystem also includes a two-port 10GbE network interface card (NIC) device to support faster downloads of FPGA bit streams into the PFA module, as well as to route between the PFE and the Routing Engine. The PFA module supports 24 GB SDRAM (DDR3) for packet memory and 72 MB of quad data rate static RAM (SRAM) (QDR2+) for low-latency processing. The module also features a high precision oscillator with external packet-per-second interfaces for precision timing support. As an application development module, the QFX-PFA-4Q is intended for customers requiring customized packet processing. However, Juniper does not provide or develop any packaged or customized solutions for the QFX-PFA module.

Similar to other QFX5100 switches, the QFX5100-24Q-AA supports rich Layer 2, Layer 3, and MPLS features. The QFX5100 also runs the same reliable, high-performance Juniper Networks Junos operating system used by Juniper Networks QFX Series switches, EX Series Ethernet Switches, Juniper routers, and SRX Series Services Gateways, ensuring a consistent implementation and operation of control plane features across the Juniper infrastructure. With its diverse set of deployment options, including Layer 3 and spine and leaf, the QFX5100 line is the universal building block for data center switching architectures, enabling users to easily adapt as requirements change over time.

Switch Deployments

Today’s data centers are built with high-performance, small form-factor, multicore blade and rack servers. The greater compute capacity and server densities enabled by these devices are increasing traffic levels, creating the need for high-speed, low-latency, storage- and I/O-converged networking solutions that can maximize performance for physical servers, virtual servers, and storage in the data center.

An immense amount of compute power is required to process these applications, which often need to interact with other applications on different servers to complete a single task. Switching between different compute resources leads to higher application latency—intolerable in use cases such as high frequency trading and Hadoop clusters. The QFX5100-24Q-AA with PFA module accelerates application processing by performing certain compute tasks on a hardware acceleration platform, lowering latency, improving performance, and lowering the cost of procuring additional compute resources.

The greatest benefit of an FPGA is its ability to perform customized processing, as well as the flexibility to change and reprogram logic as needs change. Fixed pipeline ASICs such as the PFE on the QFX5100 are designed for fast switching and routing of packets based on L2 and L3 headers. Functions that typically occur at L4 or above—such as Network Address Translation (NAT), packet encryptions, and load balancing—can easily be implemented on the QFX-PFA-4Q expansion module.

Junos OS

All QFX5100 switches run Junos OS, Juniper’s powerful and robust network operating system. The Junos operating system features the most advanced and robust routing capabilities in the industry. All QFX5100 switches include support for RIP and OSPF for both IPv4 and IPv6 in the base software. Advanced capabilities such as IS-IS, BGP, LDP, RSVP, and BGP-LU are also supported. With additional capabilities like 64-way equal-cost multipath (ECMP) and BGP add path, QFX5100 is an ideal building block for deploying the most robust L3 underlay for software-defined networks (SDN)

In addition to advanced features, Junos OS has the following additional attributes:

  • Software modularity with process modules running independently in their own protected memory space and with the ability to do process restarts
  • Uninterrupted routing and forwarding with features such as nonstop routing (NSR) and nonstop bridging (NSB)
  • Commit and rollback functionality that ensures error free network configurations
  • A powerful set of scripts for on-box problem detection, reporting, and resolution

Junos Space Network Director

The QFX5100 switches can be managed through Junos Space Network Director, a next-generation network management solution that allows users to visualize, analyze, and control the entire enterprise network—data center and campus, physical and virtual, wired and wireless—through a single pane of glass. Network Director incorporates sophisticated analytics for realtime intelligence, trended monitoring, and automation to increase agility as well as faster rollout and activation of services.

For cloud deployments, Network Director provides a set of REST APIs that enable on-demand and dynamic network services by simplifying the consumption of services for multitenant environments. With third-party cloud orchestration tool integration, the Network Director API enables automation and provisioning of Layer 2, Layer 3, and security services in the data center without the need for manual operator intervention.

Features and Benefits:

Topology-Independent In-Service Software Upgrade (TISSU*)

With its Intel core processor, the QFX5100-24Q-AA Application Acceleration switch allows Junos OS to run within a VM on Linux. Junos OS runs in two separate VMs in active and standby pairs; during software upgrade cycles, the switches seamlessly move to the newer software version while maintaining intact data plane traffic. This true topology-independent ISSU, an industry-first software upgrade feature for a fixed-configuration top-of-rack switch, is supported across all L2 and L3 protocols and doesn’t need the support of any other switches to perform an image upgrade.


The QFX5100-24Q-AA Application Acceleration switch supports a number of features for network automation and plug-and-play operations. Features include zero touch provisioning, operations and event scripts, automatic rollback, and Python scripting. The switch also offers support for integration with VMware NSX Layer 2 Gateway Services, Puppet, and OpenStack.

Flexible Forwarding Table

The QFX5100-24Q-AA Application Acceleration switch’s Flexible Forwarding Table (FFT) allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the switch supports 288,000 MAC addresses. In L3 mode, the table can support 128,000 host entries, and in LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a CLI so that each QFX5100 can be optimized for different deployment scenarios.

Intelligent Buffer Management

The QFX5100-24Q-AA Application Acceleration switch has a total of 12 MB shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5100 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.

Cloud Analytics Engine

The QFX5100-24Q-AA Application Acceleration switch supports the Juniper Networks Cloud Analytics Engine, providing critical network performance data to improve application performance and availability. Cloud Analytics Engine performs data collection, correlation, and visualization to help customers better understand workload and application behavior across the physical and virtual infrastructure.

Insight Technology for Analytics

The QFX5100-24Q-AA Application Acceleration switch provides dynamic buffer utilization monitoring and reporting, with an interval of 10 milliseconds to provide microburst and latency insight. It calculates both queue depth and latency, and logs messages when configured thresholds are crossed. Interface traffic statistics can be monitored at two-second granularity. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), comma-separated values (CSV), and tab-separated values (TSV). These files can be consumed by orchestration systems, SDN controllers, or network management applications (such as Junos Space Network Director) to make better network design decisions and identify network hotspots.


The QFX5100-24Q-AA Application Acceleration switch supports a broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. The QFX5100 can be deployed as a low-latency MPLS label-switching router (LSR) or MPLS PE router in smaller scale environments. The QFX5100 is the industry’s only compact, low-latency, high-density, low power switch to offer an MPLS feature set.

IP Clos Fabric

The QFX5100-24Q-AA switches can be used either as a leaf or as a spine and a leaf, depending on the topology (see Figures 2 and 3, respectively).

As a Fibre Channel over Ethernet (FCoE) transit switch, the QFX5100-24Q-AA Application Acceleration switch provides an IEEE data center bridging (DCB) converged network between FCoE-enabled servers and an FCoE-enabled Fibre Channel storage area network (SAN). The QFX5100 offers a full-featured DCB implementation that provides strong monitoring capabilities on the top-of-rack switch for SAN and LAN administration teams to maintain clear separation of management. In addition, FCoE Initiation Protocol (FIP) snooping provides perimeter protection, ensuring that the presence of an Ethernet layer does not impact existing SAN security policies. FCoE link aggregation group (LAG) active/active support is available to achieve resilient (dual-rail) FCoE connectivity.

The FCoE transit switch functionality, including priority-based flow control (PFC), Enhanced Transmission Selection (ETS), and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
