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 (Figure 1) 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.
Figure 1. Cisco ML-Series Cards for Cisco ONS 15454 MSPP
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. Some of the features and benefits are listed in Table 1.

APPLICATIONS
The Cisco ONS 15454 ML-Series cards provide the flexibility to meet the demands of a wide variety of network applications found within many service providers' transport networks. The following figures show a few of the applications that can be cost-effectively deployed using the Cisco ONS 15454 with the Cisco ML-Series cards.
Ethernet Service Delivery
The Cisco ONS 15454 with either the Cisco ML100X-8 or ML1000-2 Cisco ML-Series cards can be used for efficient 100BASE-FX and Gigabit Ethernet service delivery over fiber to better reach customers from a central office or point of presence (POP), refer to Figure 2. In addition, when the Cisco ONS 15454 with the Cisco ML-Series cards is placed in a telco wiring closet in the basement of a customer building, fiber from the riser can be used to more efficiently deliver 100BASE-FX and Gigabit Ethernet services. Customers can use the Cisco ML-Series cards to offer a wide range of Ethernet services with Layer 2 switching, RPR, and advanced QoS capabilities.

Interoffice Facility Networks
All traditional local exchange carriers (LEC) have used SONET/SDH technology to interconnect their central offices. With the explosion of data-related services and the growth of termination equipment with integrated Ethernet interfaces and protocols, these carriers increasingly need to transport data traffic more efficiently. Using the Cisco ML-Series cards to interconnect data traffic between the remote terminal equipment and the central core router provides transport bandwidth efficiency by statistically multiplexing and aggregating traffic for efficient router port use, reducing the quantity of core router interfaces. Management benefits are garnered through the integration of data switching into the optical platform, reducing the number of data-communication-network (DCN) ports. Figure 3 shows an interoffice facility (IOF) transport network.

Metro Data Services Network
Metropolitan networks deliver services to end-user customers. A metropolitan network that supports a wide range of service capabilities allows the service provider to offer a tariff mix to meet customer needs. The Cisco ONS 15454 provides the foundation for building an advanced multiservice network over an extremely reliable SONET/SDH infrastructure (refer to Figure 4). Data services delivery, such as transparent LAN services (TLS) or Internet access, are supported by the Cisco ONS 15454 ML-Series cards through the use of 802.1Q in the .1Q VLAN protocol, VLAN translation, input rate limiting, and advanced QoS features, including queue bandwidth control and traffic priority marking. These flexible features allow the service provider to build, control, and guarantee the delivery of the SLAs offered for each service type. To help service provider technicians manage and use the network, the Cisco ML-Series cards integrate Cisco IOS Software, the industry's best-known Layer 2 and Layer 3 technology, reducing training time and cost.

Cable Television Data Transport
Cable television operators are experiencing rapid growth of subscribers to their data services. The Cisco ONS 15454 with Cisco ML-Series cards provides a solution to efficiently transport the increasing data on cable television networks. The Cisco solution allows the cable operator to aggregate data traffic, using the Cisco ML-Series cards, from multiple secondary headends and statistically multiplex it onto shared transport bandwidth for handoff to a core router at the master headend (Figure 5). Cable modem traffic is bursty, and the sharing of bandwidth allows better use of optical transport resources compared to dedicated point-to-point connections. The advanced QoS capabilities of the Cisco ML-Series cards allow the cable network engineer to design the network to support the committed information rate (CIR) necessary for the types of services being offered, such as Web browsing, VoIP, and video on demand (VoD). The Cisco ML-Series cards allow the user to build traffic queues and associate priority and bandwidth with each queue type, allowing the transport demands of each service to be met. The Cisco ONS 15454 platform supports in-service bandwidth upgrades and allows the transport network to scale from 155 Mbps to 320 Gbps using dense wavelength-division multiplexing (DWDM) so that growth demands should be easily met.
