Key Product Differentiators

Increased Scale and Buffer
The QFX5130 provides enhanced scale with up to 1.24 million routes, 80,000 firewall filters, and 160,000 media access control (MAC) addresses. It supports high numbers of egress IPv4/ IPv6 rules by programming matches in egress ternary content addressable memory (TCAM) along with ingress TCAM.

132MB Shared Packet Buffer
Today’s cloud-native applications have critical dependency on buffer size to prevent congestion and packet drops. The QFX5130 has 132 MB shared packet buffer that is allocated dynamically to congested ports.

Programmability
The QFX5130 revolutionizes performance for data center networks by providing a programmable software-defined pipeline in addition to the comprehensive feature set provided in the Juniper Networks QFX5120 Switch line. The QFX5130 uses a compiler-driven switch data plane with full software program control to enable and serve a diverse set of use cases, including in-band telemetry, fine-grained filtering for traffic steering, traffic monitoring, and support for new protocol encapsulations.

Power Efficiency
With its low-power 7 nm process, the QFX5130 consumes a maximum of 973 W, bringing improvements in speed, less power consumption, and higher density on chip.

Features and Benefits:

• Automation and programmability: The QFX5130-32CD supports a number of network automation features for plug-and-play operations, including zero-touch provisioning (ZTP), Network Configuration Protocol (NETCONF), Juniper Extension Toolkit (JET), Junos telemetry interface, operations and event scripts, automation rollback, and Python scripting.
  
  
• Cloud-level scale and performance: The QFX5130 supports best-in-class cloud-scale L2/L3 deployments with a low latency of 630 ns and superior scale and performance. This includes L2 support for 160,000 MAC addresses and Address Resolution Protocol (ARP) learning, which scales up to 64,000 entries at 500 frames per second. It also includes L3 support for 1.24 million longest prefix match (LPM) routes and 160,000 host routes on IPv4. Additionally, the QFX5130 supports 610,000 LPM routes and 80,000 host routes on IPv6, 128-way equalcost multipath (ECMP) routes, and a filter that supports 80,000 ingress and 18,000 egress exact match filtering rules. The QFX5130 supports up to 128 link aggregation groups, 4096 VLANs, and Jumbo frames of 9216 bytes. Junos OS Evolved provides configurable options through a CLI, enabling each QFX5130 to be optimized for different deployment scenarios.
  
  
• VXLAN overlays: The QFX5130 is capable of both L2 and L3 gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN or Open vSwitch Database (OVSDB) for programming the overlays, which can operate without a controller or be orchestrated with an SDN controller.
  IEEE 1588 PTP Boundary Clock with Hardware Timestamping: IEEE 1588 PTP transparent/boundary clock is supported on QFX5130, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5130 supports hardware timestamping; timestamps in Precision Time Protocol (PTP) packets are captured and inserted by an onboard field-programmable gate array (FPGA) on the switch at the physical (PHY) level.
  
  
• Data packet timestamping: When the optional data packet timestamping feature is enabled, select packets flowing through the QFX5130 are timestamped with references to the recovered PTP clock. When these packets are received by nodes in the network, the timestamping information can be mirrored onto monitoring tools to identify network bottlenecks that cause latency. This analysis can also be used for legal and compliance purposes in institutions such as financial trading, video streaming, and research establishments.
  
  
• RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5130 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage-area network (SAN). The QFX5130 offers a full-featured DCB implementation that provides strong monitoring capabilities on the topof-rack switch for SAN and LAN administration teams to maintain clear separation of management. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
  
  
• Junos Evolved features: The QFX5130 switch supports features such as L2/L3 unicast, EVPN-VXLAN, BGP addpath, RoCEv2 and congestion management, multicast, 128- way ECMP, dynamic load balancing capabilities, enhanced firewall capabilities, and monitoring.
  
  
• Junos OS Evolved Architecture: Junos OS Evolved is a native Linux operating system that incorporates a modular design of independent functional components and enables individual components to be upgraded independently while the system remains operational. Component failures are localized to the specific component involved and can be corrected by upgrading and restarting that specific component without having to bring down the entire device. The switches control and data plane processes can run in parallel, maximizing CPU utilization, providing support for containerization, and enabling application deployment using LXC or Docker.
  
  
• Retained state: State is the retained information or status pertaining to physical and logical entities. It includes both operational and configuration state, comprising committed configuration, interface state, routes, hardware state, and what is held in a central database called the distributed data store (DDS). State information remains persistent, is shared across the system, and is supplied during restarts.
  
  
• Feature support: All key networking functions such as routing, bridging, management software, and management plane interfaces, as well as APIs such as CLI, NETCONF, JET, Junos telemetry interface, and the underlying data models, resemble those supported by the Junos operating system. This ensures compatibility and eases the transition to Junos Evolved.

Deployments:

The QFX5130-32CD can be deployed as a universal device in cloud data centers to support 100GbE server access and 400GbE spine-and-leaf configurations, optimizing data center operations by using a single device across multiple network layers (see Figure 1). The QFX5130-32CD can also be deployed in more advanced overlay architectures like an EVPN-VXLAN fabric. Depending on where tunnel terminations are desired, the QFX5130-32CD can be deployed in either a centrally routed (Figure 2) or edge-routed (Figure 3) architecture.

Architecture and Key Components:

The QFX5130 can be used in L3 fabrics and L2 networks. You can choose the architecture that best suits your deployment needs and easily adapt and evolve as requirements change over time. The QFX5130 serves as the universal building block for these switching architectures, enabling data center operators to build cloud networks in their own way.

Layer 3 fabric: For customers looking to build scale-out data centers, a Layer 3 spine-and-leaf Clos fabric provides predictable, nonblocking performance and scale characteristics. A two-tier fabric built with QFX5130 switches as leaf devices and Juniper Networks QFX10000 modular switches in the spine can scale to support up to 128 40GbE ports or 128 25GbE and/or 10GbE server ports in a single fabric.

Junos OS Evolved ensures a high feature and bug fix velocity and provides first-class access to system state, allowing customers to run DevOps tools, containerized applications, management agents, specialized telemetry agents, and more.

Junos Telemetry Interface

The QFX5130 supports Junos telemetry interface, a modern telemetry streaming tool that provides performance monitoring in complex, dynamic data centers. Streaming data to a performance management system lets network administrators measure trends in link and node utilization and troubleshoot issues such as network congestion in real time.

Junos telemetry interface provides:

• Application visibility and performance management by provisioning sensors to collect and stream data and analyze the application and workload flow path through the network
• Capacity planning and optimization by proactively detecting hotspots and monitoring latency and microbursts
• Troubleshooting and root cause analysis via high frequency monitoring and correlating overlay and underlay networks
