The Cisco® Carrier Packet Transport (CPT) 200 and 600 sets the industry benchmark as a carrier-class converged access and aggregation platform for Unified Packet Transport architectures. Cisco CPT product family represents an exciting new paradigm in the world of Packet Transport with exceptional pay as you grow scalability, carrier-class reliability, incredible flexibility, and TDM like ease of packet service provisioning, OAM and protection capability.
The Cisco CPT 200 and 600 Packet Transport Fabric (PTF) Line Card is a non-blocking switch fabric that delivers economical, scalable, highly available, and Packet Transport services through a Unified Multiprotocol Label Switching (MPLS) network layer. The PTF 256 Gigabit non-blocking switch fabric interconnects all Packet Transport line cards over the backplane while providing scalability and high availability active-active architecture. In addition, the PTF delivers four 10-Gigabit Ethernet ports that can be used for User-to-Network Interfaces, Network-to-Network Interfaces, and enables extension of GE interfaces through the CPT 50 satellite architecture. The PTF enable the Cisco CPT 200 and 600 provide a robust MPLS-Transport Profile (TP) infrastructure to deliver scalable Private Line, Business, Residential, Mobile Backhaul, Data Center, and Video Services (Figure 1).

Features and Benefits
Cisco CPT 200 and 600 PTF offers:
• 256 Gbps of non-blocking fully redundant switching fabric
• Distributed forwarding and control planes for higher performance
• Modularized system components in both hardware and software, isolating failure and faults to subsystem and component
• Hardware-based signaling for the fabric: support for near zero packet loss on switchover
• Built-in redundancy in hardware components such as the route switch processor (RSP), switch fabric, control-plane chassis control bus, and power supplies, thereby avoiding a single point of failure
• 4 port of 10Gbps Ethernet Interfaces that operate as UNI, NNI, & Satellite architecture extension
• Hardware based Bidirectional Forwarding Detection (BFD) processing and control that provide transport SLA detection times
With integrated synchronization circuitry and dedicated backplane timing traces for accessing the shelf controllers Stratum-3 subsystem, the CPT 200 and 600 PTF Line Card provides standards-based line-interface functions for delivering and deriving transport-class network timing, enabling support of network-synchronized services and applications such as mobile backhaul and migration of TDM services.
The PTF also consolidating Unified MPLS transport and DWDM networking by integrating the G.709 OTN layer with both I.7 and I.4 Enhanced Forward Error Correction (EFEC) into two 10GE ports. The G.709 provides visibility into the DWDM transmission system to permit rapid detection and recovery from transmission-layer and DWDM impairments and G.709 can also be configured for proactive protection if signal degradation is detected; it prevents traffic loss and link outage. The Enhanced Forward Error Correction extends transmission-layer performance, delivering extended performance over an amplified system without the cost of regeneration or transponders.

Flexible Ethernet services
• Ethernet Virtual Connections (EVCs): Ethernet services are supported using individual EVCs to carry traffic belonging to a specific service type or end user through the network. EVC-based services can be used in conjunction with MPLS-based L2VPNs and native Ethernet switching deployments.
• Flexible VLAN classification: VLAN classification into Ethernet flow points (EFPs) includes single-tagged VLANs, double-tagged VLANs (QinQ and 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists.
• IEEE Bridging: The line cards support native bridging based on IEEE 802.1Q, IEEE 802.1ad, and QinQ VLAN encapsulation mechanisms.
• Resilient Ethernet protocol (REP): The REP provides a resilient, fast-convergence mechanism for aggregating and connecting to Ethernet-based access rings.
• MPLS-TP Circuit with Ethernet over MPLS-TP (EoMPLS-TP): EoMPLS-TP transports Ethernet frames across an MPLS-TP LSPs using pseudowires. Individual EFPs or traffic from an entire port can be transported over an MPLS-TP network using pseudowires to an egress interface or sub-interface.
• Virtual Private LAN Services (VPLS): These services are included in a class of VPN that supports the connection of multiple sites in a single bridged domain over a MPLS-TP network. VPLS presents an Ethernet interface to customers, simplifying the LAN and WAN boundary for service providers and customers, and enabling rapid and flexible service provisioning, because the service bandwidth is not tied to the physical interface. All services in a VPLS appear to be on the same LAN, regardless of location.
• Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire in case of failure.
• Multi-segment pseudowire stitching: Multi-segment pseudowire stitching is a method for interworking two pseudowires together to form a cross-connect relationship.
• Span is a technique of replicating the ingress or egress frames in a specific port to a specified list of destination ports. It is a monitoring feature used to monitor the traffic that is coming out of a port or an EFP. The monitored traffic can be used to debug the network and can also be used by law enforcement agencies.
• MPLS-TP: 1:1 MPLS TP LSP delivers protection switching for networks with sub-50ms APS switching for link, node, path failures.
• Bidirectional Forwarding Detection (BFD): BFD is a detection protocol that is designed to provide fast forwarding path-failure detection times for all media types, encapsulations, topologies, and routing protocols
• 802.3ad Link Aggregation Bundles: The line cards support a bundle of multiple links to provide added resiliency and the ability to load balance traffic over multiple member links.
• IGMP v2 and v3 snooping: This Layer 2 mechanism efficiently tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level or pseudowire level. In residential broadband deployments, this scenario enables the network to send only channels that are being watched to downstream users.
• Multicast VLAN Registration (MVR): MVR optimizes the control plane (IGMP) load between the router and switch. MVR feature enables switch to aggregate different JOINs received on different VLANs (from the receivers) into one JOIN (on a single VLAN, which could be the same as or different from the VLANs of the receiving ports) towards the router. The switch then distributes (replicate) the received content into the relevant ports.
• Connectivity Fault Management (CFM) Ethernet layer OAM protocol provides end-to-end provider edge (PE to PE) and/or customer edge to customer edge (CE to CE) fault management. CFM includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet metropolitan-area networks (MANs) and WANs. CFM is defined by IEEE 802.1ag standard.
• Ethernet Link OAM is a protocol for installing, monitoring, and troubleshooting Ethernet metropolitan-area networks (MANs) and Ethernet WANs. It relies on an optional sublayer in the data link layer of the Open Systems Interconnection (OSI) model. Ethernet Link OAM is defined by IEEE 802.3ah standard.
• Remote Ethernet Port Shutdown. The Remote Ethernet Port Shutdown replicates a local link failure over an EoMPLS pseudowire to a remote link shutdown the remote Ethernet port down. Bot UNI interfaces connected to the EoMPLS pseudowire will shutdown in the event of a pseudowire failure.
• ITU Y.1731 Fault Management and Delay Management. The ITU-T Y.1731 feature provides OAM functions for fault management and performance monitoring functionality for service providers in a large network. ITY Y.1731 includes Ethernet Alarm Indication Signal (ETH-AIS), Ethernet Remote Defect Indication (ETH-RDI), Ethernet Locked Signal (ETH-LCK) functionality for fault detection and isolation. ITU Y.1731 Delay Management (DM) provides a standard Ethernet PM function that includes measurement of Ethernet frame delay and frame delay variation.
• IP/MPLS OA&M: LSP Ping & LSP Trace Route
• Pseudo-Wire: Virtual Circuit Connectivity Verification (VCCV), Ping, Traceroute, Static Status Message to LDP Status Message Translation
• MPLS-TP OA&M: GACH/GAL & MPLS-TP LSP BFD OAM
