Sprint Implements 40 Gbps IP-over-DWDM using Cisco/Ciena

Sprint is deploying 40 Gbps network trunks in its Tier 1 IP backbone using IP-over-DWDM (IPoDWDM) technology.

The implementation of IPoDWDM drives efficiencies by eliminating client connections between the router and DWDM system and increasing bandwidth four times by transmitting 40-Gbps across an existing 10-Gbps DWDM system. The companies said the integration of router and DWDM transponder components reduces network complexity and increases the scalability and resiliency of the backbone. IPoDWDM can also position Sprint to rapidly move to higher data rates (e.g., 100-Gbps) without overhauling the network infrastructure.

Earlier this year, Sprint completed final testing of the 40-Gbps IPoDWDM technology and enabled their first production 40-Gbps circuit. The implementation uses the Cisco CRS-1 Carrier Routing System with built-in transponders along with Ciena's CoreStream Agility platform to transport the wavelength across the fiber-optic network. To date, several 40-Gbps circuits have been deployed, and those are carrying commercial IP-based services.

Sprint, which is deploying the Cisco CRS-1 Carrier Routing System across its global network, conducted the first 40-Gbps technology trial with live-production traffic in 2004. Sprint began deploying them in its IP core network in 2006. Today, Sprint CRS-1 routers are deployed in more than 25 U.S. cities.

Sprint began deploying Ciena's CoreStream platform in its Tier 1 IP backbone in 2000 and currently has more than 1,000 nodes deployed.

Cisco Enhances IP-over-DWDM, Doubling Reach for 40 Gbps

Cisco announced a set of enhancements to its IP-over-DWDM technology (IPoDWDM), which is available on its core Carrier Routing System (CRS-1). These include new modules that can provide data throughput at 40 Gbps across existing 10 Gbps networks. The solution is positioned as a core transport architecture for handling the surge of traffic from video over the Internet.

The list of enhancements includes:

  • Doubling the reach of the Cisco CRS-1 40-Gbps IPoDWDM to 2,000 kilometers without regeneration. The new 40Gbps physical line module interface supports deployments in virtually any geographic area.

  • Extending the power of Cisco IPoDWDM solution to the network's edge on the Cisco XR 12000 and 12000 Series Routers with a new 10 Gigabit Ethernet shared port adapter that enables instant bandwidth up to 10 Gbps over 2,000 kilometers.

  • Reducing provisioning on the Cisco ONS 15454 platform with an omni directional and colorless mesh reconfigurable optical add-drop multiplexer (ROADM). This will decrease truck rolls and lower the requirements for power, space and cooling by more than 50 percent.

  • Increasing resiliency with proactive protection feature that guards video and mission-critical data against fiber cuts by resetting failover benchmarks to 15 milliseconds (ms), three times faster than the industry standard of 50 ms.

  • Enhancing the ability for service providers to deploy with separate data and transport departments with virtual transponder - now transport departments can directly manage the optics integrated into the router.

Alcatel-Lucent Endorses MPLS-Transport Standardization Efforts

Alcatel-Lucent announced its commitment and support for MPLS-Transport Profile (MPLS-TP), building on the standardization efforts by the International Telecommunications Union (ITU) Telecommunication Standardization Sector (ITU-T) and the Internet Engineering Task Force (IETF). Enhancing MPLS with transport operational practices - including operation, administration and maintenance (OAM) and survivability - is expected to help carriers scale their transport networks while adding performance monitoring and multi-domain capabilities.

Alcatel-Lucent said it is committed to enabling seamless transformation of transport networks to converged MPLS-based packet transport. It has already added MPLS techniques to transport networks through its 1850 Transport Service Switch (TSS) portfolio -- where the current version of MPLS-Transport, the ITU-T T-MPLS, is already implemented and under test with several service providers -- and its 7450 Ethernet Service Switch (ESS) portfolio, which is deployed worldwide in carrier networks using MPLS pseudowires. This new effort brings these two related approaches together and delivers one unified set of MPLS-based packet transport standards.

"Alcatel-Lucent believes MPLS is the optimal technology to enable scalable Ethernet transport in carrier networks and has taken a leadership role in implementing MPLS-based packet transport" said Michel Rahier, President of Alcatel-Lucent's carrier activities. "We are fully committed to MPLS and MPLS-TP and will continue to develop a full range of products based on common specifications, working closely with service providers and other vendors to ensure interoperability."
  • In June, Alcatel-Lucent unveiled a network architecture that integrates Provider Backbone Bridging (PBB) and Virtual Private LAN Service (VPLS) technologies to increase the scale and reach of Carrier Ethernet VPN services. Whereas many vendors support PBB on Ethernet Switches and others support MPLS on routers, Alcatel-Lucent's architecture combines the scalability benefits of PBB and the resiliency, traffic engineering and convergence benefits of VPLS and MPLS. The integrated PBB and VPLS solution is especially aimed at enhancing network and service scalability - both in terms of reach and MAC addressing.
