Foundation for Next-Generation Transport: The Cisco Carrier Packet Transport System

November 15, 2010 - 0 Comments

SONET and SDH, while well established and highly reliable technologies, were optimized for an era of TDM voice communications – before cloud computing, VoIP, cell phones, mobile tablets, Video CDNs and even the Internet increased network complexity and radically changed traffic patterns. This infrastructure has delivered reliable transport because it is easy to provision, troubleshoot, and provides a high level of resiliency. However, with the increase in IP traffic and changing traffic patterns, a new solution is required: one that provides the ‘trust’ of SONET/SDH with the ‘efficiency’ and ‘agility’ of packet.

Today Cisco is announcing our latest innovation, the Cisco Carrier Packet Transport (CPT) System. Our goal is to enable the transport network in a way that combines the reliability and simplicity of point-and-click provisioning of SONET/SDH along with the efficiency and flexibility of IP/MPLS. 

Service providers generate a lot of revenue from connection-oriented services like leased lines. However the growth of these services from a revenue perspective is slow. New services based on cloud, mobile, and video are IP based and have huge growth potential. Service providers need to address this growing traffic and need to do so profitably. They need to find ways to lower the cost of transport and simultaneously tap into new applications that increase the average revenue per user. The Cisco Carrier Packet Transport System helps them do exactly that!

Of course, new technology can be overwhelming. So, it’s important to deliver all the benefits of packet technology without sacrificing the trust of transport. With the Cisco CPT System, service providers can build a packet transport infrastructure with the same reliability and familiar operational models of SONET/SDH. Standards-based MPLS-TP allows for robust packet connection-oriented control. Cisco’s Premier Integrated Management Experience (PRIME) offers service providers an A-Z point-and-click network management system. Both wavelengths and MPLS-TP label switch paths are provisioned in an easy “point-and-click” fashion autonomously or from a single integrated domain. This integrated solution provides opex savings and eliminates the need for overhaul and extensive employee re-training.

The Cisco Carrier Packet Transport System is truly the industry’s first integrated Packet-Optical Transport System (P-OTS) and “greenest” solution. By integrating DWDM, OTN, Ethernet and MPLS-TP, service providers can consolidate functionality and realize savings anywhere from 60 to 65 percent in space and power. In addition, the CPT 600 or CPT 200 can connect to multiple CPT 50 satellite platforms for cost-effective expansion. The CPT 50 can reside locally or remotely and be managed as one system to provide additional opex savings.

Finally, the Cisco Carrier Packet Transport System supports standards-based MPLS-TP. This allows service providers to interoperate with existing IP/MPLS networks for complete investment protection and longevity.  By allowing service providers to enable new services while supporting existing services, the Cisco CPT System delivers the foundation for next-generation transport networks.

Don’t just take our word for it. Several service providers have voiced their support for the Cisco Carrier Packet Transport System for their networks. Please visit to learn more about the Carrier Packet Transport (CPT) System.
