The Alcatel-Lucent 1870 Transport Tera Switch (TTS) is a new optical core switching platform providing terabit capacity and Optical Transport Network (OTN) capabilities for the next-generation intelligent optical core. It is ideally suited to large-scale backbone transport networks, enabling providers to manage explosive service and bandwidth growth efficiently while transporting traffic at the lowest cost per bit. It also provides the highest availability and resiliency for improved service quality assurance, and offers advanced operational automation that minimizes the total cost of ownership (TCO) of service provider infrastructures.

Leveraging the latest silicon innovation, the 1870 TTS features a set of unique capabilities including an industry-first switching architecture with state-of-the-art 4 Tb/s capacity (ready to upscale to 8 Tb/s) and a 120 Gb/s per slot backplane in a single compact chassis. This provides the highest-density for the lowest power per transported bit. The 1870 TTS integrates OTN with multiple transport networking options, including Carrier Ethernet and SDH and SONET, for the most efficient bandwidth management from low-rate signals (GE/STM-1/OC-3) up to 40G and 100G; and includes GMPLS/ASON control plane intelligence for cross-layer automation, highly resilient transport and dynamic bandwidth provisioning across multiple transport networking layers for the highest network efficiency.

The Alcatel-Lucent 1870 TTS shifts transit traffic-handling burdens away from core routers through OTN based lambda-, port- and sub-port-level IP-traffic grooming, helping reduce the cost of transport according to a service provider’s specific traffic mix and approach to network integration. In combination with the Alcatel-Lucent 7750 Service Router (SR) and Alcatel-Lucent’s portfolio of photonic switches and optical cross-connects, the 1870 TTS supports the Converged Backbone Transformation solution, a key component of Alcatel-Lucent’s High Leverage Network^TM strategy. It offers a flexible range of traffic grooming options that enable efficient core router traffic offload onto the optical network and help scale the IP backbone, facilitating transport at the most economical layer.

Benefits:

• Solves the cost-capacity crunch, scales the IP core
  • Supports traffic growth while controlling the costs with a backbone network architecture that is highly efficient for bandwidth management, handling the traffic explosion at the most economical layer and ensuring proper power efficiency.
  • Shifts transit traffic-handling burdens away from core routers through OTN based lambda-, port- and sub-port-level IP-traffic grooming, helping reduce the cost of transport (IP offload).
  • Introduces intelligence and automation for optimizing network resources and operations—reducing TCO, ensuring the highest availability and quality assurance for higher revenue potential.
• Mazimizes bandwidth monetization
  • As cost per transported bit is reduced, revenues per transported bit are improved by introducing high-level automation and intelligence that maximize reuse of available bandwidth for new, paying traffic.
• Simplifies operations, reduces TCO
  • Introduces GMPLS control plane intelligence for restoration and dynamic bandwidth provisioning.
  • Introduces OTN networking that ensures the transport-grade operational model of SDH/SONET is inherited, allowing for the management of any bit-rate traffic pipes with scalability up to 100G.

Features:

• 4 Tbps capacity single chassis, power efficient switching architecture (ready to upscale at 8 Tb/s and downscale at 1 Tb/s and 2 Tb/s)
  • Supports huge traffic growth in a cost-controlled manner by building large-scale transport infrastructures that offer the capacity for efficient bandwidth management of any traffic mix (TDM/packet) and support the scalable, sustainable delivery of next-generation IP services at the lowest cost per bit.
  • Leverages latest 65 nanometer silicon innovation, switches packet and circuit traffic in their native formats..
• OTN networking
  • Provides the most efficient sub-wavelength bandwidth management capabilities for high bit-rate traffic relations up to 40Gb/s and 100Gb/s.
  • Supports lambda, port and sub-port grooming options for optimized scaling of the IP core (part of the Alcatel Lucent High Leverage Network^TM and Converged Backbone Transformation solution), shifting transit traffic-handling burdens away from core routers and handling the traffic explosion at the most economical layer.
  • Enables individual management of traffic relations that are a fraction of DWDM rates, and that need individual forwarding, operations, monitoring and SLA assurance across the network for efficiency.
  • OTN reuses the same well-known operational model of SDH/SONET bandwidth management, ensuring that transport-grade OAM and protection tools are extended to the new higher bit rates, minimizing the number of transport bearers necessary for each transported service. This simplifies network operations, reuses operational skills and optimizes overall TCO.
  • SDH/SONET networking is supported for seamless integration into existing assets, allowing for smooth evolutionary upgrades of the installed base.
• GMPLS/ASON cross-layer automation
  • Offers highly available transport backbones that are resilient to multiple failures, with multiple restoration options for improved and differentiated SLA assurance.
  • Reduces OPEX, as less intensive on-site interventions are necessary in the event of network failures.
  • Maximizes traffic monetization, as fewer network resources are required for protection and can be reused for improved network efficiency.
  • Enables automated, dynamic service provisioning across the most economical resources in the network for optimized network utilization and power efficiency.
  • Leverages our experience with more than 60 real-world deployments.
