Juniper Networks ATM and ATM2 IQ
Physical Interface Cards (PICs) offer flexible, highly-available
solutions for the termination of ATM access networks, and provide
support for the progressive transition to an all-IP/MPLS infrastructure.
The ATM2 IQ PICs provide a very rich and robust set of quality
of service (QoS) and traffic management features aimed at facilitating:
- The seamless and progressive network transformation from a legacy ATM backbone to an all-IP/MPLS infrastructure
- The introduction of new revenue-generating IP services to ATM-connected enterprises, such as Layer 2 and Layer 3 provider-provisioned
VPNs
ATM2 IQ Physical Interface Cards (PICs)
Supported by both the Juniper Networks M-series and T-series
routers, the ATM2 Intelligent Queuing (IQ) PICs are available
in 4-port DS3, 2-port and 4-port E3, 2-port OC-3, 1-port OC-12,
and 2-port OC-12 versions. The ATM2 IQ PICs leverage the JUNOS
operating system's MPLS traffic engineering and hardware-based
QoS capabilities to deliver seamless transport of multiservice
traffic over the IP/MPLS infrastructure. Designed to provide
rich, granular ATM QoS and signaling functionalities, the
ATM2 IQ PICs are a key element in the delivery of a guaranteed
high-quality, end-to-end user experience.
Features and Applications
As bandwidth needs continue to increase, migrations of legacy data service and voice traffic to a converged IP/MPLS infrastructure must maintain the premium-quality service levels that users expect and rely upon. Hard-won brand equity and service revenues must be protected, and service degradation is intolerable.
Juniper Networks understands these critical considerations,
and delivers the hardware and software-based solutions to
gracefully migrate business-critical traffic from ATM environments
to a converged IP/MPLS network infrastructure. The ATM and
ATM2 IQ PICs are central enablers of this network transformation,
and are based upon a very robust set of JUNOS IP/MPLS and
ATM service capabilities.
Examples of applications enabled by the ATM and ATM2 IQ PICs
include:
Multiservice transport over MPLS
- Circuit Cross-Connect for multiservice transport over an IP/MPLS infrastructure
- Comprehensive support for "draft Martini" encapsulation
- Ethernet over ATM (per RFC 2684)
VPN Services
- Support for Layer 3 provider-provisioned VPNs over ATM interfaces
- Support for Layer 2 provider-provisioned VPNs
- Support for Virtual Private LAN Services (VPLS)
- Full suite of additional VPN services
