Release 9.2.1 of this tool has evolved significantly from the original, simpler version, to support the new and advanced functions provided by the Cisco ONS 15454 MSTP.

This tool was originally developed to help create BoMs for customer-specific designs. The Cisco Transport Planner tool supports you from the design phase to the deployment phase of a DWDM network. The Cisco ONS 15454 MSTP solution can help you design, maintain, and optimize your DWDM network to maximize network performance and save on operational costs.Ĭisco Transport Planner Product Overview and Applications These benefits surpass those that are available from a simple hardware-based solution.

Cisco Transport Controller: You can use this integrated tool to support installation and provisioning at the network level.

Intelligent optical transmission software: Each network element can automatically support transport functions in the DWDM domain similar to those in the SONET, SDH, and data domains, defining what is now considered next-generation DWDM transport.

DWDM units: A complete set of DWDM transport and aggregation units helps deliver simple, fast, and intelligent optical capabilities.

Cisco Transport Planner: This Java-based application helps users model and design DWDM networks based on the Cisco ONS 15454 MSTP.

The Cisco ONS 15454 MSTP offers a complete solution for designing, provisioning, and maintaining an optical DWDM network, including: The network design tool needs to account for and support this flexibility to verify and support the different optical paths existing in the network. ROADM in DWDM networks is expected to provide complete flexibility in the traffic pattern. When fixed OADM units are used for capacity add/drop in the different sites of the network, the design needs to optimize the numbers and types of units used in each node to reduce overall network cost.

Type and number of services required in each network locationīased on these constraints, a DWDM network design should optimize the hardware placement in the different network nodes to minimize the cost of the design.

Distance and insertion loss of the network spans.

The design and optimization of a DWDM network is an interactive process that requires consideration of all the constraints of the system: Metro and metro-regional DWDM networks, which usually require many add/drop locations, have an additional layer of complexity because the same network supports different optical paths that must use the same common optical units (such as optical amplifiers and dispersion compensation units). Linear effects include noise accumulation, optical power budget, and chromatic dispersion effects nonlinear effects include cross-phase modulation, self-phase modulation, and four-wave mixing.

Many different parameters must be accounted for because of linear and nonlinear effects.

The intelligent DWDM functions of the Cisco ONS 15454 MSTP dynamically monitor and adjust wavelength power and signal conditions to help ensure optimal compliance with service-level agreements (SLAs), giving providers proactive control over a customer’s service experience.ĭesigning DWDM networks has always been a complex task because of the intrinsic nature of optical transmission, which is based on analog technology despite the transport of digital signals. The benefits of designing with Cisco Transport Planner extend beyond deployment to the in-service phase supported by MSTP features that significantly reduce the operating expenses (OpEx) traditionally associated with wavelength-division multiplexing (WDM) networks and optical add/drop multiplexers (OADMs) by automating labor-intensive operations. The output from Cisco Transport Planner provides content beneficial to both the design and deployment phases, including system performance reporting, bill-of-materials (BoM) generation, graphical layouts of racks and shelf configurations, optical connections between nodes, and downloadable provisioning and configuration settings for each optical node. Cisco Transport Planner uses the latest in optical transport technologies from the Cisco Optical portfolio, featuring the Cisco ONS 15454 MSTP with fully integrated multidegree ROADM technology, to help engineer the optimal DWDM infrastructure capable of any-to-any service delivery for linear, ring, multiring, and mesh networks. The Cisco Transport Planner is a fully comprehensive DWDM network design and design management tool (for example, delta planning, rack layout definition, and cabling procedure) that allows Cisco ONS 15454 MSTP customers to concentrate on service definition and availability while radically simplifying the process of comparing alternative service-delivery and investment scenarios.
