Changing market dynamics have intensified the challenge of accommodating growth with traditional products and architectures. Juniper's secure and automated multicloud solution helps cloud-based networks quickly react to these evolving conditions, accelerating service delivery with world-class products and innovative architectural components. PTX Series Packet Transport Routers with custom ExpressPlus silicon are an integral part of this solution, delivering a massively scalable and efficient core architecture across space- and power-constrained service provider and enterprise networks, reducing TCO with innovative, highly flexible, highperformance platforms that are easy to deploy.
Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at a low cost. Three fixed-configuration platforms are available: the PTX1000 Packet Transport Router, the industry's first 2 U packet transport routing device; the PTX10001 Packet Transport Router, the industry's first 1 U packet transport device optimized for cost-optimized transit routing, the PTX10002 Packet Transport Router, a secondgeneration device that doubles the density of the PTX1000 with Juniper Networks ExpressPlus™ silicon in addition to the PTX10003, the industry's first 3U 400-GbE enabled packet transport routing device. These packet transport routers give cloud and communication providers the freedom to develop and deliver new virtualized services anywhere in the network. They can also create an elastic architecture with precise traffic control 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. 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:
In order to address these challenges, cloud and communication providers need an innovative core router that satisfies three defining principles: performance, deployability, and SDN programmability. The PTX1000, PTX10001, PTX10002 and PTX10003 fixed-configuration packet transport routers provide the foundation for a scale-out core backbone architecture, ensuring a consistent user experience across geographies. The PTX1000, PTX10001, PTX10002 and PTX10003 meet all existing traditional core requirements, easily fitting into cloud and communication provider networks that require transitfocused IP/MPLS applications such as Internet peering, scaleout metro and backbone topologies, and label-switching router (LSR) optimized deployments.
The PTX10001, which offers MACsec on all 10GbE, 40GbE, and 100GbE interfaces, is designed for low-buffer, lowforwarding information base (FIB), low-power, and high-density LSR core applications.
The PTX1000, PTX10001, PTX10002 and PTX10003 fixedconfiguration packet transport routers bring physical and virtual innovation to the service provider core network, addressing concerns about operational expenditures while scaling organically to keep pace with growing traffic demands with the following features:
Physical innovations at the core silicon level enable the PTX Series fixed-configuration routers to reduce OpEx. Powered by ExpressPlus silicon, these devices build upon the Juniper Networks Junos® Express silicon concepts of low consistent latency and wire-rate packet performance for both IP traffic and MPLS transport, without sacrificing the optimized system power profile. These concepts are incorporated into the PTX Series design along with full IP functionality, preserving the spirit of the original Junos Express chipset. The ExpressPlus silicon is the first purpose-built telecommunications silicon to engineer a 3D memory architecture into the base design for more than 1.6 billion filter operations per second, dynamic table memory allocation for mammoth IP routing scale, and enormous power efficiency gains. While the PTX10001 has inbuilt MACsec, it does not have external memory. The PTX10003 supports inline MACsec on all 10/100/100/400GbE interfaces.
The PTX1000, with its rich IP/MPLS feature set, lets service providers organically distribute peering points throughout the network without sacrificing performance and deployability-the main contributors to eroding TCO for service providers when peering. The PTX1000 expands the applications scope that the PTX Series architecture addresses, enabling service providers to implement a distributed core architecture for interconnecting growing cloud services. Service providers can distribute peering points to match traffic demand with an optimized core router without sacrificing performance or deployability. The PTX1000 is a first-generation fixed-configuration core router in a compact, 2 U form factor, making it easily deployable in space-constrained Internet exchange locations, remote central offices, and embedded peering points anywhere in the network, including cloud-hosted services.
The PTX1000 operates at 2.88 Tbps in a fixed core router configuration and supports flexible interface configuration options, including 288 10GbE ports via a quad small form-factor pluggable plus transceiver (QSFP+) breakout, 72 40GbE ports via QSFP+, and 24 100GbE ports via QSFP28.
The PTX10001 is a MACsec-enabled LSR core router featuring a compact, 1 U form factor that is easy to deploy in spaceconstrained backbone environments. Operating at 3.6 Tbps in a fixed core router configuration, the PTX10001 supports flexible interface options, offering 36 physical QSFP28 100GbE ports, 36 QSFP+ 40GbE ports, and 144 10GbE ports via QSFP+ breakout cables. MACsec is enabled on all interfaces.
The PTX10002 is a second-generation PTX Series fixedconfiguration core router featuring a compact, 2 U form factor that is easy to deploy in space-constrained Internet exchange locations, remote central offices, and embedded peering points throughout the network, including cloud-hosted services.
The PTX10002 operates at 6 Tbps in a fixed core router configuration. It supports flexible interface configuration options, offering 60 physical quad small form-factor pluggable 28 (QSFP28) 100GbE ports, 60 QSFP+ 40GbE ports, and 192 10GbE ports via QSFP+ breakout cables.
The PTX10003 is a fixed-configuration core router featuring a compact, 3 U form factor that is easy to deploy in spaceconstrained Internet exchange locations, remote central offices, and embedded peering points throughout the network, including cloud-hosted services. The PTX10003 uniquely addresses power-constrained environments by providing unprecedented power efficiency of 0.2 watts/Gbps. Two versions of the PTX10003 are available, supporting 8 Tbps and 16 Tbps respectively in a 3 U footprint.
Operating in a fixed core router configuration, the 8 Tbps model features flexible interface configuration options with universal multi-rate QSFP-DD for 100GbE/400GbE/FlexE to support 160 (QSFP+) 10GbE ports, 80 (QSFP28) 100GbE ports, 32 (QSFP28- DD) 200GbE ports, and 16 (QSFP56-DD) 400GbE ports.
The 16 Tbps model also offers universal multi-rate QSFP-DD for 100GbE/400GbE/FlexE to support 320 (QSFP+) 10GbE ports, 160 (QSFP28) 100GbE ports, 64 (QSFP28-DD) 200GbE ports, and 32 (QSFP56-DD) 400GbE ports.
Performance is one of the guiding design principles for the PTX Series Packet Transport Routers. This focus empowers service providers with superior scale to match increased traffic levels and network engineering challenges with predictable system latency to improve the overall service experience, deliver best-in-class resiliency, and ensure that services meet strict customer servicelevel agreements (SLAs). Deployability is the other guiding design principle for the PTX Series routers, focusing on power, space, and weight-fundamental concerns that impact service providers' operational budget with respect to growing traffic.
Infinite programmability with automation and telemetry brings virtual innovations to the service provider core, while the NorthStar Controller is an open, standards-based solution that optimizes both the IP layer and the transport layer with precise SDN control, allowing service providers to automate and scale operations
