Motorola today revealed the details on three upcoming devices in its C-Port Network Processor Family: the 3 Gbits/second C-3e Network Processor (NP), the Q-3 Traffic Management Coprocessor (TMC) and the TDM Channel Adapter.
The new products are specifically targeted for access networking equipment such as 2.5G/3G Wireless Infrastructure, Media Gateways, Cable Modem Termination Systems (CMTS), DSLAMs, and Multiservice Access Platforms.
The C-3e NP architecture uses eight Channel Processors for physical interface connections, packet/cell data parsing, and protocol transformation. The Channel Processors also integrate Ethernet MACs (10/100, Gigabit) and SONET/SDH framers (OC-3/STM-1, OC-12/STM-3) that can help lower overall system costs.
The C-3e NP also includes eight Services Processors that can be used concurrently for processing more advanced functions (such as SARing, traffic management, and encapsulated protocol processing), and built-in coprocessors for accelerating classification, buffer management, and traffic management tasks.
The architecture can address and adapt to virtually any protocol, such as: AAL-1, AAL-2, AAL-2 SSSAR, AAL-5 SAR, ATM TM 4.1, IMA, IPv4, IPv6, UDP, RTP, GTP, Header Compression, L4 Port Classification, VoIP, ICMP, PPP (Multi-Class, Multi-Link, PPP-MUX), IP DiffServ, MPLS, PoS, Frame Relay, and HDLC.
For access applications requiring advanced flow-based traffic management – from 4Kbits/second up to 1 Gbit/second – system designers can add the Q-3 TMC, which provides ATM TM 4.1 and IETF Diffserv-compliant policing, shaping, monitoring, and scheduling of up to 64k flows/connections.
The Q-3 TMC can support up to 4096 virtual channels that can be rate limited to conform to a particular downstream link bandwidth, such as an xDSL link, or have minimum bandwidth guarantees with weighted fair sharing on the excess bandwidth available at the virtual port or interface.
For aggregating many TDM interfaces into the C-3e NP, Motorola’s forthcoming TDM Channel Adapters will aggregate 8 to 16 TDM lines consisting of multiple, independent, logical channels into a single C-3e NP Channel Processor, enabling the C-3e NP to support aggregation of up to 256 T1/E1 lines with up to 2048 logical channels of HDLC, ATM, and transparent data.
Tools and applications that support C-3e NP development are available today in the C-Ware Software Toolset version 2.1, allowing OEMs to start coding and simulating C-3e NP applications now.
The C-3e NP is expected to sample in the third quarter of 2002 with the suggested list price of $225 in 10K quantities. The Q-3 TMC is expected to sample in the third quarter of 2002 with the suggested list price of $235 in 10K quantities. The first of Motorola’s TDM Channel Adapter products is expected to sample in the fourth quarter of 2002.
