QoS for Ethernet, ISA-Ethernet Switch ISA-ES

When the ubiquity of the optical- network platforms deployed today is considered, optical technologies represent one of the most compelling opportunities for service providers to leverage their installed base and deliver new revenue-generating services (see Figure 2).

Alcatel-Lucent OMSN products can be deployed with traditional MSPPs from the Alcatel-Lucent portfolio and emerging packet optical transport devices in the Alcatel- Lucent 1850 Transport Service Switch (TSS) portfolio.

ISA-Ethernet Switch (ISA-ES)

modules enable new, highly-available

Layer 2 Ethernet service delivery

in the metro network through their MPLS-enabled Ethernet.

With the ISA-ES equipped Alcatel- Lucent OMSN nodes, service providers can enhance their service offerings with Metro Ethernet Forum (MEF)- certified Ethernet services for business and residential customers.

QoS for Ethernet

As well as mapping Ethernet customer flows onto SDH network resources through standardized mechanisms, the ISA-ES series cards introduce wire-speed classification, policing and scheduling capabilities on a carrier-class Ethernet switching blade. These capabilities provide

a cost-effective solution for building multiservice aggregation infrastruc tures that are scalable, reliable and capable of per-service SLA/QoS support with:

•Scalable service delivery based on virtual local area network (VLAN), Q-in-Q or MPLS technologies, extended by efficient SDH bandwidth- management capabilities

•Sub-50 ms service resilience based on SDH

•Per-flow and per-service SLA guarantees offer accurate band width profiles according to different customers’ applications, to create a measurable, differen tiated Ethernet service portfolio and increase service profitability by ensuring QoS-specified Ethernet service delivery in any network condition, including faults and congestion.

The ISA-ES blades allow service

providers to deliver more than just Ethernet connectivity service over the optical metro infrastructure.

These modules enable service providers to climb up the value chain and offer the new revenue-generating services that both business and residential users are demanding.

1662, 1660 specifications

The Alcatel-Lucent 1660 and 1662 series are pivotal elements in the realm of optical networking, designed to meet the increasing demands for bandwidth while providing flexibility and scalability. These platforms are part of Alcatel-Lucent’s comprehensive portfolio of networking solutions, emphasizing the need for efficient communication in a rapidly evolving digital landscape.

One of the key features of the Alcatel-Lucent 1660 series is its support for multiple services across a unified platform. This versatility allows service providers to deliver a range of services, including traditional voice, data, and newer, bandwidth-intensive applications, all within a single infrastructure. The ability to handle various wavelengths and protocols ensures that the system can adapt to varying customer requirements without necessitating significant hardware changes.

The Alcatel-Lucent 1660 is built upon the Dense Wavelength Division Multiplexing (DWDM) technology, which significantly increases the capacity of optical fibers. By allowing multiple signals to travel simultaneously over a single fiber, the 1660 series can maximize existing networks and reduce the cost per bit of data transmission. This is particularly advantageous for service providers looking to expand their offerings and reach without extensive investment in new infrastructure.

In terms of characteristics, the series is known for its modular architecture. This design enables operators to easily upgrade and expand their systems as demand grows. The platform can be configured with a variety of plug-in cards and modules that support different data rates and protocols, allowing for a customized solution tailored to specific operational needs.

Moreover, reliability is at the forefront of the Alcatel-Lucent 1660 and 1662 series. With built-in redundancy options and robust fault management capabilities, operators can ensure uninterrupted service, a critical factor in today’s always-on society. The systems are designed to provide high availability and low latency, crucial for applications such as video conferencing, telemedicine, and cloud services.

Another noteworthy aspect is the management capabilities facilitated by the Alcatel-Lucent management software. This software provides operators with advanced monitoring and troubleshooting tools that enhance overall operational efficiency. The intuitive interface allows for easy configuration and maintenance, reducing the operational burden on network administrators.

In conclusion, the Alcatel-Lucent 1660 and 1662 series epitomize modern optical networking solutions that combine flexibility, scalability, and reliability. By leveraging DWDM technology and providing modularity, these platforms are equipped to handle current and future bandwidth demands, making them an excellent choice for service providers seeking to enhance their telecommunications infrastructure. Whether for urban deployments or long-haul applications, the Alcatel-Lucent 1660 and 1662 series represent a forward-thinking investment in networking technology.
