The Cisco® Carrier Ethernet (CE) Card (Figure 1) for the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP) helps enable the delivery of true carrier-class, private-line Ethernet services. Through its portfolio of Ethernet service cards, the Cisco ONS 15454 has helped enable service providers and enterprises to effectively and efficiently migrate their networks from offering/transporting only time-division-multiplexing (TDM) services to networks capable of multiservice delivery over a single, converged architecture and eliminating the need for multiple overlay infrastructures. The introduction of the CE-Series module, with generic framing procedure (GFP), virtual concatenation (VCAT), and link capacity adjustment scheme (LCAS) helps service providers and enterprises maximize bandwidth utilization and promote industrywide interoperability for Ethernet private line services. The Cisco ONS 15454 MSPP is the optical industry’s first metro optical transport platform. The Cisco ONS 15454 combines supercharged SONET/SDH transport, integrated optical networking (ITU grid wavelengths and dense wavelength-division multiplexing [DWDM], for example), and unprecedented multiservice interfaces on demand (TDM, Ethernet/IP, and storage, for example) to deliver radical economic benefits. The Cisco ONS 15454 provides the functions of multiple network elements in a single platform. As a critical component of a complete, end-to-end advanced service architecture from Cisco Systems®, the Cisco ONS 15454 delivers a scalable optical transport mechanism and intelligent Ethernet/IP support required to cost-effectively deliver next-generation voice and dataservices. Cisco continues its tradition of converged network services leadership with the introduction of the CE-Series and the Cisco ONS 15454 MSPP CE 8-port 10/100Base-T Ethernet Card, which helps enable the efficient delivery of private-line Ethernet services without a major overhaul or redesign of existing transport infrastructure. The Cisco CE 8-port Ethernet Card is a single-slot line card offering 8-port, 10/100-Mbps Ethernet via standard RJ-45 interfaces. Traffic from the eight interfaces is encapsulated into a SONET/SDH payload using either GFP or framing based on high-level data link control (HDLC). The resulting packet-over-SONET/SDH (POS) traffic is then mapped into a SONET circuit for transport across the network. These circuits form a one-to-one relationship with the eight front-panel ports and are referred to as virtual concatenated groups (VCGs). Each VCG uses low-order or high-order contiguous and/or virtual concatenation mechanisms to determine circuit sizing. The card also supports LCAS, which allows hitless dynamic adjustment of SONET/SDH link bandwidth. Additionally, each card supports packet processing, classification, queuing based on quality of service (QoS), and traffic-scheduling features, all required for supporting advanced services delivery.
