Background
Information connectivity in today's world is becoming increasingly more ubiquitous and commonplace as businesses and consumers look 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, dial-up, cable TV modem, etc.) and wireless (cell, PCS, 802.11b, etc.) vehicles. The key benefit to this information connectivity is user access to a wide variety of information that can be located anywhere in the world.
Ethernet technology has become ubiquitous as the protocol of choice for the LAN environment. It is also becoming increasingly commonplace in the MAN, with the release of fast- and Gigabit-Ethernet interfaces on DSLAMs, fixed wireless, and PBXs. Thus, the service
provider is being driven to create tariffs to efficiently interconnect to and transport the user's data traffic via Ethernet hand-offs and must deploy metro transport equipment that will enable 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 SP's metro networking equipment must support both the traditional TDM-based services as well as newer Ethernet-based services, without a forklift upgrade, and is why the multiservice provisioning platform has taken hold of the metro marketplace.

industries 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 ONS 15454 ML-Series consists of two interface cards, models ML100T-12 and ML1000-2. The ML100T-12 is a 12-port, 10/100 Mbps Ethernet module. The ML1000-2 is a two-port gigabit Ethernet module utilizing SFP optical interface modules. The 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 an ONS 15454 shelf assembly, and can be mixed and matched within the assembly or network to enable flexible architectures to meet the user's application. 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, enabling efficient matching and scalability of ingress to transport traffic requirements, based upon over-subscription requirements.
The ML-Series cards offer an advanced set of quality of service (QoS) features to allow the network administrator to fine-tune the network and enable the creation and support of a wide range of SLAs. Some of the features and benefits are captured below:
Feature
Benefit
Flexible packet classification Classify packets based upon input port, VLAN, CoS, IP Precedence, or IP differentiated services code points (DSCP). This enables the service provider to tailor the packet handling based upon the user's traffic.
Policing
Highly granular input port policing allows the service provider to contain a user to the SLA bandwidth requirements. Reduces the possibility of a user flooding the network.
Priority marking
Provides a mechanism, when using either .1Q or Q in Q features for a service provider to reclassify (mark) a packet with a wrapper Ethernet 802.1p value, enabling downstream nodes to treat the packet differently. This feature enables the packet's original CoS bits to be transported transparently across a service provider network.
Per class queuing
Provides fair access to excess network resources, allows allocation of bandwidth to support SLAs, and ensures applications with high network resource requirements are adequately serviced.
Weighted deficit round robin Adds additional weighting capabilities to deficit round robin scheduling to provide
(WDRR) Scheduling
fair access to excess bandwidth as well as guaranteed throughput to each class.
Admission control
During service provisioning, the ML-Series card verifies that QoS resources have not been accidentally over-committed.

The ML-Series cards offer key advantages in service provider network architectures, enabling new, profitable services as well as simplifying service activation. Some of these capabilities are outlined below:
Feature Network scaling and flexibility
Packet over SONET Virtual ports (POS) support
Lower interface costs
Benefit
The ML-Series cards support VLAN-ID translation. This capability enables the service provider to change the ingress VLAN tags (802.1Q or 802.1Q in.1Q) to avoid VLAN collisions within their network (resulting from different customers using the same VLAN-ID) and translate them back at the egress of the network.
POS support enables the service provider to transport Ethernet traffic originating on an ML-Series card over an optical interface and terminate the signal on an optical port of existing L2/L3 equipment. Eliminates the need to bookend the ML-Series cards within the network.
The use of the ML-Series cards and shared bandwidth transport allows the service provider to leverage the benefits of statistically multiplexing the edge traffic before handing off a more efficiently filled interface to the core router or switch.
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 diagrams outline a few of the applications that can be met using the ML-Series cards.
Inter-Office Facility (IOF) Networks
All traditional local exchange carriers (LEC) have utilized SONET/SDH technology to interconnect their central offices (see Figure 2). With the explosion of data-related services and the growth of termination equipment, with integrated Ethernet interfaces and protocols, these carriers have a growing need to transport data traffic more efficiently. Leveraging the ML-Series cards to interconnect data traffic between the remote terminal equipment and the central core router will allow transport bandwidth efficiency by statistically multiplexing and aggregating traffic for efficient router port utilization, reducing the quantity of core router interfaces. Management benefits are garnered through the integration of data switching into the optical platform, reducing data communication network (DCN) ports.

Metro Data Services Network
Metropolitan networks deliver services to end user customers. As such, a metropolitan network that supports a wide range of service capabilities will allow the service provider to offer a tariff mix to meet the customers needs. The Cisco ONS 15454 provides the foundation for building an advanced multiservice network over an extremely reliable SONET/SDH infrastructure (see Figure 3). Data services delivery, such as transparent LAN services (TLS) or Internet access, are supported by the ONS 15454 ML-Series cards through the use of 802.1Q in .1Q VLAN protocol, VLAN translation, input rate limiting and the advanced QoS features, including queue bandwidth control and traffic priority marking. These flexible features enable the service provider to build, control, and guarantee the delivery of the SLAs offered for each service type. It is also very important for the network to be manageable and usable by the service provider's technicians. As such, the ML-Series cards integrate Cisco IOS, the industry's most well known Layer 2/ 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. According to the National Cable Television Association (NCTA), data cable subscriptions grew 337 percent from January 2000 to January 2002. The Cisco ONS 15454 with ML-Series cards provides a solution to efficiently transport the growing data requirements of the cable television networks. The Cisco solution will enable the cable operator to aggregate data traffic, using the ML-Series cards, from multiple secondary headends (SHE) and statistically multiplex it onto shared transport bandwidth for handoff to a core router at the master headend (see Figure 4). Cable modem traffic is bursty in nature, and the sharing of bandwidth enables better utilization of optical transport resources versus dedicated point-to-point connections. The ML-Series cards' advanced QoS capabilities enable the cable network engineer to architect the network to support the type of services being offered such as Web browsing, Voice over IP, or video on demand (VOD). The ML-Series cards allow the user to build traffic queues and associate priority and
