新闻大意：在3年里花掉16亿美刀的研发费用以后，Cisco终于成功推出CRS-3 100G核心网络路由器。CRS-3最多支持1152插槽，支持322Tb/s的吞吐量。已经交付at&t Labs测试，良好处理100G 40G 10G混合网络路由的测试情况令人满意。狂人钱伯斯再次放出狠话“我们是通信领域的Intel，Microsoft，Dell的混合体。”该产品仍在场测中，秋季正式供货，起步价9万美刀。

对于Cisco来说，这是占有100G网络的极其重要的一部，对于他的竞争者，如Juniper来说，是一份无情的挑战书。对于我等来说，这表明100G的网络要真的来了，are u ready?

/ u0 ^5 A. L& z$ o2 X/ S9 j5 LSAN JOSE, Calif. — Cisco Systems announced its next generation core router, the CRS-3. The new system can route 100 Gbit/second streams and sports an aggregate throughput of up to 322 Terabits/second. AT&T Labs said it has tested the system in field trials as part of its plans to transition from 40 to 100 Gbit/s backbone networks over the next few years. In February, industry groups gave updates about the status of work on first generation100 Gbit Ethernet and faster serial links for follow on products. The CRS-3 provides as much as three times the throughput of Cisco's existing CRS-1 core router, more than 5,000 of which are now in use with about 300 carriers. It aims to help service providers handle rising video and mobile data traffic. Cisco said the CRS-3 will provide new levels of intelligence for routing traffic including automated capabilities to set up virtual private networks over cloud services. The system, now in field trials, will be available in the fall at prices starting at $90,000. The CRS-3 is powered in part by a set of six ASICs Cisco called the Quantum Flow Array Processors. The name harkens back to the processor in a Cisco edge router launched in March 2008. In communications, "we are the Intel, Microsoft and Dell combination all together," said John Chambers, Cisco's chief executive in a Web conference launching the CRS-3. "I have always believed you have to do your own silicon," he said. The ASICs include packet, queuing, fabric and interface processors that fit on each line card in the system with as many as 16 cards in a chassis. The CRS-3 is Cisco's first router to span multiple cabinets. Keith Cambron, president and chief executive of AT&T Labs, said AT&T tested the CRS-3 handling a mix of 100, 40 and 10 Gbit traffic on a commercial link between Miami and New Orleans. "I am confident it can handle the traffic load with the error performance we wanted, and no co-channel interference," Cambron said in the teleconference. "In 2008, we deployed a 40G backbone with the Cisco CRS-1 and we are already seeing routes where 40G is not enough," Cambron said. "We are putting in multi-lanes of 40G in some places [but] we are still a few years from finalizing plans [for 100G lanes]," he said. AT&T's network handled 40 percent more traffic in 2009 than it did in the previous year, he added. Cisco spent three years and an estimated 1.6$ billion developing the CRS-3. ; x' G1 Q* v+ B5 n
In October, Cisco competitor Juniper Networks rolled out a new generation of edge router products for service providers and large businesses. The Cisco CRS-3 will compete with core routers from Alcatel-Lucent and others. / ^" q; J1 l$ X! N' C" W

2 O" B, P, ]0 E+ S ~1 T4 zModels include: - Cisco CRS-3, powered by Cisco QuantumFlow Array - a chipset architecture engineered in multiple dimensions of scale, services, and savings
- Cisco CRS-1, built on the Cisco Silicon Packet Processor (SPP)
Packet-based data communications are being replaced by video and rich media crossing the IP Next-Generation Network (NGN) in multiple directions. As part of a medianet, a media-aware Cisco IP NGN, Cisco CRS eases this strain on networks. It efficiently handles the multidirectional traffic of network and data center cloud interactions. # H2 u8 l, N: _+ M2 C7 `) `! {
The Cisco CRS: - Delivers continuous operations
- Scales easily from numerous single-chassis form factors to a massive multichassis system, up to 322 Tbps
- Provides industry-leading efficiency, requiring low power, cooling, and rack-space use for intelligent, service-rich bandwidth capacity
Cisco CRS-3 models build on the CRS-1 models' backward and forward compatibility, protecting your existing and future investments for decades to come.
