glad to help, L.
interestingly, i wonder how that AMCC partnership for physical-layer interfaces will continue to evolve ... <g>
fwiw, i did some digging on their three products QoSCore, AnyLCore and ATMLCore. not that i firmly grasp it all, mind you (e.g., WTF is a "leaky-bucket shaper?").
QoSCore is a queuing and interworking engine; chip includes an ATM AAL-5 segmentation-and-reassembly (SAR) device, an ATM/frame relay interworking circuit and a dual leaky-bucket shaper. can be used alone in some applications for SARing, shaping and scheduling traffic or in conjunction with the other two products.
AnyLCore is a capsulation/decode and search engine capable of translating between Ethernet, frame relay, Point to Point Protocol and ATM protocol stacks.
ATMLCore is AnyLCore's "ATM cousin"; uses hardwired state machines to support 256,000 secure flows, embedding all operations, administration and maintenance support for ATM virtual circuits.
each will sample at OC-48 (2.5-Gbit/second) speeds; design of OC-192 (10-Gbit) versions has begun, however, they are not expected to be completed until early 2001.
evaluation samples of QoSCore and AnyLCore are due in may; ATMLCore to follow in july. manufacturing partner is NEC. |
