Opportunity
This particular assignment demanded a full range of Frame
Relay and ATM equipment interconnection, spanning campus and
wide area applications by using private lines and/or public
ATM services. The project also had the daunting task of designing
a complex ATM-based backbone network.
Aricent Solution
Aricent had been involved extensively in the development of this
Switch to form a core design team for architecture designs,
hardware and software design of the components, network design,
protocol design, design and implementation of drivers, diagnostics
and provide support for operating system services.
Aricent was primarily involved in the following, design of Adaptation
modules to support multiple access offerings such as Native
ATM, FR based on ATM UNI 3.0 and FR Forum standards, design
of ATM services based on Traffic Types (UBR, CBR, VBR, VBR-nrt,
VBR-rt), Connection Admission Control, Congestion Management,
Traffic Policing, design and specification of the hardware
architecture for the ATM switching and adaptation modules.
Other important modules comprised defining System Software
Architecture and specification of protocols for nodal protocols,
definition of Core APIs to allow transparent network access
to multiple access protocols, implementation of IP over ATM
for switch management (RFC 1577), fast redundancy switchover
to optimize the time taken by the backup module to take-over
from the primary module.
Network Management and Access Services
The product is provided with a comprehensive package of network
management tools, supporting and enhancing its basic functionality.
The product family provides a wide selection of network access
services.
- Frame Relay to Frame Relay PVC (via Broadband
Switch) and Frame Relay to ATM PVC (via Broadband Switch)
- ATM to ATM PVC (via Broadband Switch)
- T1 to T1 circuit transport (via Broadband
Switch) and T1 to ATM circuit emulation service (via Broadband
Switch)
- E1 to E1 circuit transport (via Broadband
Switch) and E1 to ATM circuit emulation service (via Broadband
Switch)
- Frame Relay PVC, SVC and Transparent PVC
(via Interface Switch)

- X.25 PVC and X.25 SVC (via Remote node or
Interface Switch)
- IP over Ethernet or Token Ring (via Remote
node or Interface Switch)
Success Story
The productline Aricent assisted the client with turned
out to be an award winning ATM Network Switch (BX5000), which
at present is used as enterprise wide area backbone network
for data, voice and video applications. It supports full redundancy,
hot swappable modules, robust permanent virtual connection
routing and state-of-the-art network management ensuring that
mission critical applications are not interrupted.
