Network & Communication

The Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at the lowest cost per bit. Two fixed-configuration platforms are available: the PTX10001-36MR Packet Transport Router, a compact, power-optimized 400GbE platform based on custom Express4 silicon; and the PTX10003, the industry's first 3U 400-GbE enabled packet transport routing device. These transport routers give cloud and communication providers the freedom to develop and deliver new virtualized services anywhere in the network with elastic architectures and precise traffic controls, without compromising the service experience.

The Evolving Landscape

New traffic dynamics such as mobility, video, and cloud-based services are transforming traditional network patterns and topologies. Stratified, statically designed, and manually operated networks must evolve to support the constantly growing volumes of traffic quickly and economically. Many operators have seen their profits stagnate and TCO grow under the burden that these growing traffic volumes are imposing. Cloud and service providers need to become more agile in order to optimize their existing network resources, shorten planning cycles, and remove rigid network layers.

Operators are facing the following challenges under the current environment:

• Static scale: The cloud and communication providers' backbone handles the full weight of network traffic. Therefore, it is paramount that core networks are inherently designed for scalability and efficiency. The 400GbE-capable platforms, 100/400GbE inline MACsec, silicon, system, and SDN innovations for the core empower network operators to scale faster than the traffic in an elegant, elastic, redundant package- without requiring forklift upgrades.
• Static architecture: Virtualized services and the explosion of cloud-based applications are creating increasingly unpredictable traffic patterns. To handle this unpredictability, service providers need a dynamic, scale-out architecture across all layers to create programmable, traffic-optimized networks that support any service, anywhere.
• Power costs: For cloud and communication providers, the operational cost of transmitting a packet through the core is less than the cost of the power required to move that packet. In fact, projections suggest that over a few short years, the total power draw will exceed the cost of deploying the entire network infrastructure. Efficient power utilization by the core router requires a holistic ground-up engineering approach.
• Facility limitations: Service providers cannot grow their facilities exponentially forever. They need innovations that provide a low-touch deployment model optimized around space availability, facility power requirements, and floor weight thresholds.

The QFX5210 is a flexible, 64- port, fixed-configuration switch designed for spine-and-leaf applications in next-generation IP fabric networks. Featuring line-rate, high-density QSFP+/ QSFP28 ports supporting 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE connections, the QFX5210 offers an advanced L2, L3, and MPLS feature set. This allows network operators to build large, high-density IP fabrics that support network virtualization and intelligent traffic forwarding based on proven, Internet-scale technology, while enabling easy upgrades to 25GbE and 50GbE servers.

Product Description

Network operators are increasingly deploying scale-out spine-and-leaf IP fabric architectures built with fixed-configuration switches to support growing east-west traffic in the data center. The Juniper Networks® QFX5210 Switch is a next-generation, fixed-configuration spine/leaf switch that offers flexible, cost-effective, high-density 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE interfaces for IP fabric networks, providing deployment versatility, investment protection, and future-proofing for today's data centers. The QFX5210 Switch's high port density also contributes to simplified Clos architectures, eliminating network tiers while reducing complexity and cost.

Like other QFX Series switches, the QFX5210 supports advanced Layer 2, Layer 3, and MPLS features. For large public cloud providers-among the first to adopt 25GbE and 50GbE servers to meet explosive workload growth-the QFX5210 enables very large, dense, and fast IP fabrics based on proven Internet scale technology.

The QFX5210 runs the same reliable, high-performance Juniper Networks Junos® operating system used by network operators around the world.
