Cisco Cisco ONS 15454 M6 Multiservice Transport Platform (MSTP) 데이터 시트

Page 3 of 8

The Cisco ONS 15454 M2 MSTP provides capital and operational efficiency by addressing the increasing demand

for bandwidth and multiple services at the edge of the network. It uses the existing Cisco Transport Controller

management and integrates well with other optical transport platforms. With innovative technology, the Cisco ONS

15454 M2 MSTP pushes intelligence to the edge of the network, thus allowing the optimization of next-generation

networks across multiple layers and removing costly optical-electrical-optical (OEO) devices for network

segmentation or regeneration.

The Cisco ONS 15454 M2 MSTP carries on the existing features such as multilayer graphical network, node, and

card visibility; A-to-Z network-based service provisioning; and graphical software wizards to simplify and speed

user operations for such tasks as initial network turn-up; service provisioning; and network, node, and bandwidth

upgrades. The Cisco ONS 15454 M2 MSTP takes advantage of the embedded software architecture and control

plane to introduce a level of operational simplicity unheard of in DWDM networks.

In addition to the integrated software features, the Cisco ONS 15454 M2 MSTP is supported by an easy-to-use but

powerful network design tool, the Cisco Transport Planner. The Cisco Transport Planner is a user-friendly, Java-

based application (fully developed and tested by Cisco) for modeling and optimizing DWDM networks based on the
user’s network parameters.

Topology Flexibility

One recent core network trend is the consolidation of multiple Layer 2/3 networks into a single IP/Multiprotocol

Label Switching (IP/MPLS) infrastructure. In spite of this Layer 2/3 convergence, however, the underlying transport

layer (Layer 1) of many service provider core networks has continued to use SONET/SDH. Many service provider

networks globally still use SONET/SDH today, creating OpEx and CapEx concerns for service providers as well as

the challenges of profitability and return on investment (ROI). Some network inefficiencies result from the way core

transport networks are built out today to support the IP or service layer over the SONET/SDH layer, supported by

an underlying DWDM infrastructure. The OEO conversions and the associated electrical processing directed by the

layered network architecture result in an additional cost in terms of space, because many racks of shelves may be

required in a service provider point of presence (POP), as well as the additional power and cooling that is

necessary because of the active electronics components that they contain.

You can configure the Cisco ONS 15454, ONS15454 M6, and ONS 15454 M2 MSTP chassis to support any edge,

metro, regional, or core DWDM topology, allowing you to use a unified solution for the overall network,

independently from the topology and reach. The ultimate topology flexibility is achieved through a set of fully

reconfigurable optical add/drop multiplexers (ROADMs). Multidegree ROADMs (2 through 8 degrees of freedom)

allow wavelengths to remain in the optical domain while being passed from one ring or network segment to

another, further eliminating the need for OEO conversions and using the ability of core routers to initiate DWDM-

compatible wavelengths.

The Cisco ONS 15454 M2 MSTP with the single-module ROADM offers a tremendous decrease in footprint, power

requirements, and patch-cable complexity over the first-generation ROADM. You can use the SM-ROADM in an

M2 for edge DWDM solutions where east and west are on separate nodes.
