Motorola, Hughes to Demo Network Processor-based ATM Switch

3/25/2003 - Motorola Computer Group, a part of Motorola, Inc. (NYSE: MOT), and Hughes Software Systems Limited (HSS), specialists and leaders in convergent network software, will be demonstrating the separation of the data and control planes in a network processor-based ATM switch controlled via the General Switch Management Protocol (GSMP).

The demonstration uses a general-purpose processing blade based on PowerPC® architecture to provide GSMP control and run the Asynchronous Transfer Mode (ATM) control plane and Motorola's award-winning Packet Processor Resource Board (PPRB) to do the switching. The demo, which also features Motorola's award-winning Multi-Service Packet Transport Platform (MXP3121), uses GSMP to set up and tear down the ATM connections.

Key benefits of the GSMP solution developed by HSS include:

The Motorola and HSS application allows a user to add, delete and move connections; receive port statistics; report connection activity; and receive asynchronous event reports for the switch. The flexible nature of the MXP and GSMP architecture enables network equipment providers to quickly incorporate other protocols, such as IP routing and Multi-Protocol Label Switching, in the same platform.

"This application is the first step toward having a unified control plane architecture that will work with multiple bearer plane cards in a single chassis," said Keith Williamson, system architect, Motorola Computer Group. "This also allows for centralized system management, coherent resource reservation, virtual partitioning and load balancing. Further, it allows our OEM customers to change the underlying bearer-plane hardware without having to change the control plane interfaces to the external world."

"This demo showcases the ability of HSS control-plane software to leverage Motorola bearer-plane network processing for delivering flexible solutions to network equipment providers," said Manoranjan Mohapatra, chief operating officer, Hughes Software. "This solution demonstrates HSS's capability in delivering leading edge technology solutions for new product design which enable Motorola's customers to achieve a higher return on investment while enhancing their new services and making the infrastructure future-proof."

About the MXP3121
The MXP3121 supports the PICMG® 2.16 CompactPCI Packet Switching Backplane (CPSB) standard. The platform addresses the need for network equipment providers to handle different types of traffic over different networks including Internet Protocol (IP), Asynchronous Transfer Mode (ATM) and circuit-switched (TDM). With the ability to support an embedded dual star Gigabit Ethernet switching topology, the MXP3121 allows for embedded Ethernet solutions that eliminate the need for external switching and cables associated with legacy platform architectures. This enables the PPRB network processing subsystem, for example, to communicate over the backplane at high data rates in a highly available environment.

To support the potentially heavy processing requirements for this traffic, the MXP platform supports up to 18 slots for network processors or general-purpose processors.

About the PPRB
The Packet Processor Resource Board (PPRB) is a network processing subsystem that combines the power of ASIC-built data plane solutions with the flexibility of a programmable system. The PPRB combines the power and flexibility of Motorola's C-Port C-5 network processor with the general-purpose processing power and connectivity to provide a wirespeed blade capable of manipulating up to 2.5Gb/s of multi-protocol traffic from layer 2 to layer 4 and beyond.

About HSS GSMP Solution
The General Switch Management Protocol (GSMP) is a general-purpose protocol to control any label switches like ATM, FR or MPLS. GSMP has been selected by the Multi-service Switching Forum (MSF) as a protocol of choice for the Switch Control Interface identified in their architecture.

This general-purpose protocol that controls label switches, is an asymmetric protocol that allows one or more external switch controllers to establish and maintain the state of a label switch. It allows control of both unicast and multicast, switch connection-state as well as control of switch system resources and QoS features.

This solution has been seamlessly integrated with the above state-of-art Motorola platforms.

About HSS Software
HSS provides data-plane, control-plane and application protocol stacks and integrated interfaces required to build the RNC, Node B, SGSN, GGSN, MSC/VLR, HLR, BSS, CGF, SCP, etc., and to build telecom systems across the Voice over Packet, SS7 and Broadband domains. By acting as a global hub for standards-based protocol stack development and as a guarantor for multi-vendor interops, HSS avoids the duplication of investments across firms and hence improves the efficiency of the telecom industry as a whole.
