Table 1 below provides a hardware feature summary describing both features and benefits of the Enhanced Gigabit Ethernet Optical Services
Module:
Table 1.
Hardware Feature Summary
Feature
Benefit
Support for 4 WAN Gigabit Ethernet interfaces per module, each of
which delivers high-performance packet services, with up to 8000
traffic queues per module
Delivers sophisticated packet service capabilities on a per-user basis
over high-performance Gigabit Ethernet interfaces
Support for an additional 2 LAN Gigabit Ethernet interfaces per
module
Provides simultaneous WAN and LAN access to satisfy diverse
applications
Throughput of up to 6 Mpps per Parallel Express Forwarding (PXF) IP
services processor, with 2 PXFs per module, for a total of 12 million
packets per second (Mpps) per module
Delivers high throughput while simultaneously supporting
sophisticated packet services, such as QoS and traffic shaping
Upgradable programmed feature set using a Cisco PXF Network
Processor
Provides greater flexibility than traditional ASIC-based interface cards,
while delivering performance similar to application-specific integrated
circuit (ASIC)-based designs
Compatibility with either the Cisco 7600 Series Internet Router or the
Cisco Catalyst® 6500 Series Switch chassis (system requirements
defined below)
Provides investment protection for customers, whether they have an
installed base of Cisco 7600 Series or Catalyst 6500 Series chassis
ENHANCED OPTICAL SERVICE MODULES
The Enhanced Gigabit Ethernet OSM interface card is a member of the new family of Enhanced OSMs for the Cisco 7600 Series. This family
of interface cards supports all features of the original Cisco 7600 Series OSM interface cards, but takes the Cisco 7600 Series platform to a
higher level of performance and functionality. Some of the primary feature differences between the original and the Enhanced OSMs include
those listed in Table 2.
Table 2.
Comparison of the Original and the Enhanced Cisco 7600 Series OSMs
Enhancement
Benefit
Increase in direct memory access (DMA) memory from 64 MB to 256
MB per PXF network processor
Support for larger traffic-shaping queues. The Enhanced OSMs
support a minimum of 8000 QoS queues per OSM module.
Increase from 256 to a maximum of 1023 VRFs (VPN [virtual private
network] routing/forwarding) per chassis for MPLS Layer 3
configurations
Increased service density per chassis for support of MPLS VPN
services for end users.
Support for enhanced QoS features, such as Weighted Random Early
Detection (WRED), Class-Based Weighted Fair Queuing (CBWFQ),
Low Latency Queuing (LLQ), and traffic shaping
Improved delivery of service-level agreements to end customers.
Future support for Layer 2 network services, such as (VPLS) Virtual
Private LAN Service based on MPLS technologies
Ability to deliver Layer 2 services, such as Frame Relay, Ethernet,
and ATM, and Layer 3 services, such as Internet access and 2547
VPNs, in a consolidated network architecture.
