BACKGROUND
Information connectivity is becoming ubiquitous as businesses and consumers look for ways to improve their productivity. Access to this information can be over a wide variety of networks, including the many forms of wire-line (DSL, T1, E1, dialup, cable modem, fiber to the premises, and so on) and wireless (cell, 802.11, WiMAX, and so on) vehicles. The main benefit of this information connectivity is user access to a wide variety of information that can be located anywhere in the world.
Ethernet technology has become the protocol of choice for the LAN environment. It is also becoming increasingly commonplace in metropolitan-area networks (MANs) with the release of Fast Ethernet and Gigabit Ethernet (GE) interfaces on DSL access multiplexers (DSLAMs), fixed wireless, and private branch exchanges (PBXs). Thus, service providers are creating tariffs to efficiently interconnect to and transport users' data traffic using Ethernet handoffs, and they must deploy metropolitan (metro) transport equipment that will permit them to deliver these services cost-effectively and with the reliability required by their service-level agreements (SLAs). Although Ethernet-based services are growing, they are still not the dominant share of the market demand. Therefore, the service provider's metro networking equipment must support both traditional time-division multiplexing (TDM) services as well as newer Ethernet services without a major upgrade - this explains why the multiservice provisioning platform has taken hold in the metro marketplace.

PRODUCT OVERVIEW
The Cisco ML-Series cards for the Cisco ONS 15454 MSPP are industry-leading Ethernet and IP switching modules for integration into a SONET/SDH optical transport platform. The cards extend the multiservice capabilities and flexibility offered by the Cisco ONS 15454 platform.

Through the integration of the industry's most widely deployed and tested Ethernet and IP technology, Cisco IOS Software, with the industry's most successful multiservice provisioning platform, the Cisco ONS 15454, service providers and enterprise customers are provided with a single integrated platform for delivering true carrier-class Metro Ethernet, TDM, and optical transport services and applications.
The Cisco MultiLayer-Series (ML-Series) for the Cisco ONS 15454 consists of three interface cards: the Cisco MultiLayer (ML) 100X-8, MultiLayer (ML) 100T-12, and MultiLayer (ML) 1000-2 models. The Cisco ML100X-8 is an 8-port, 100-Mbps Ethernet interface card that supports the 100BASE-FX short-reach Small Form-Factor Pluggable (SFP) and 100BASE-LX long-reach SFP. The Cisco ML100T-12 is a 12-port, 10/100-Mbps Ethernet module. The Cisco ML1000-2 is a 2-port Gigabit Ethernet module using SFP optical interface modules. The Cisco ML-Series cards use a common hardware and software base, providing the same Layer 2 and Layer 3 feature set. These single-slot cards can be installed in any of the 12 multiservice interface slots in a Cisco ONS 15454 shelf assembly and can be mixed and matched within the assembly or network to provide flexible architectures to meet the user's application needs. Each card has virtual interfaces that are mapped to SONET/SDH optical interfaces for transport with other services between network elements over 155-Mbps to 10-Gbps optical line rates. Packet transport bandwidth over the chosen optical interface is provisionable, allowing efficient matching and scalability of ingress to transport traffic requirements, based upon oversubscription requirements.
The Cisco ML-Series cards support proprietary Resilient Packet Ring (SW-RPR), which provides increased bandwidth usage over a SONET/SDH ring. SW-RPR features also include shortest-path selection and spatial reuse for bridging. The Cisco ML-Series offers standards-based 802.17b RPR. In addition to the features of SW-RPR, 802.17b RPR benefits include steering protection and standardized ring fairness.
The Cisco ML-Series cards offer an advanced set of quality-of-service (QoS) features to allow the network administrator to fine-tune the network and create and support a wide range of SLAs.
