Chapter 12 Configuring Quality of Service on the ML-Series Card

Configuring QoS

Table 12-2

Traffic Policy Commands (continued)

 

 

 

Command

 

Purpose

 

 

ML_Series (config-pmap-c)# bandwidth

Specifies a minimum bandwidth guarantee to a traffic class in periods of

{bandwidth-kbps percent percent}

congestion. A minimum bandwidth guarantee can be specified in kbps or

 

 

by a percentage of the overall available bandwidth.

 

 

Valid choices for the ML-Series cards are:

 

 

• Rate in kilobits per second

 

 

• Percent of total available bandwidth (1 to 100)

 

 

If multiple classes and bandwidth actions are specified in a single policy

 

 

map, they must use the same choice in specifying bandwidth (kilobits or

 

 

percent).

 

 

Note When using the bandwidth command, excess traffic (beyond the

 

 

configured commit) is allocated any available bandwidth in

 

 

proportion to the relative bandwidth commitment of its traffic

 

 

class compared to other traffic classes. Excess traffic from two

 

 

classes with equal commits has equal access to available

 

 

bandwidth. Excess traffic from a class with a minimum commit

 

 

might receive only a minimum share of available bandwidth

 

 

compared to excess bandwidth from a class with a high commit.

 

 

Note The true configurable bandwidth in kilobits per second is per port

 

 

and depends on how the ML-Series card is configured. The show

 

 

interface command shows the maximum bandwidth of a port (for

 

 

example, BW 100000 Kbit). The sum of all bandwidth and priority

 

 

actions applied to the interface, plus the cos priority-mcast

 

 

bandwidth, is not allowed to exceed the maximum bandwidth of

 

 

the port.

ONS 15310-CL, ONS 15310-MA, Cisco ONS 15310-MA specifications

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.

In conclusion, the Cisco ONS 15310-MA and ONS 15310-CL models represent sophisticated solutions for modern optical networks. With their versatile features, advanced technologies, and robust design, they empower service providers and enterprises to build resilient, high-capacity networks that meet the demands of today’s data-driven world.
