Cisco introduces ‘Carrier Packet Transport System’

Cisco Systems (San Jose, CA, USA) today announced a solution designed for migrating service provider transport infrastructures to support next-generation IP-based services, called Carrier Packet Transport (CPT). The company claims this solution combines the reliability of the transport network with efficiencies of packet technology to deliver current and future services.


Cisco Systems (San Jose, CA, USA) today announced a solution designed for migrating service provider transport infrastructures to support next-generation IP-based services, called Carrier Packet Transport (CPT). The company claims this solution combines the reliability of the transport network with efficiencies of packet technology to deliver current and future services.

According to Cisco, the dynamic and distributed nature of video, mobility and cloud computing services drastically alter network traffic patterns and drive tremendous network traffic growth. Today’s time-division multiplex (TDM) technology, with synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), is no longer sufficient to handle advanced new services efficiently.

The Cisco CPT system merges the traits of a packet network in a transport platform to adapt transport networks to new applications while hopefully reducing capex costs. Cisco says their CPT system also provides robust resiliency, predictability, and comprehensive operations, administration and maintenance capabilities.

This is the first platform in the industry to support standards-based multiprotocol label switching transport profile (MPLS-TP), which interoperates with MPLS offered on routing products like the Cisco ASR 9000 Series Aggregation Services Routers and Cisco CRS-3 Carrier Routing System (CRS).

Cisco reports the CPT system achieves an impressive 60 percent reduction in rack space by combining multiple interface layers into one, which translates into a 65 percent power savings.

CPT models will be available in six-rack units (Cisco CPT600) and two-rack units (Cisco CPT200), along with a satellite device (Cisco CPT50). The Cisco CPT system supports MPLS-TP Ethernet with quality of service and virtual local area network manipulation capabilities, as well as optical transport network and reconfigurable optical add-drop multiplexer functionality.

The system is currently in field trials with several service providers–thought to be Verizon (New York, NY, USA) and BT (London, UK)–and is scheduled to be available in the first quarter of 2011.
