Juniper Networks Introduces the Next-Generation Core Router for the New Network
Industry’s Fastest Core Router Designed to Support Multimedia and Advanced Cloud Services for the New Network with Unmatched Investment Protection
SUNNYVALE, Calif., Nov. 15, 2010 — Juniper Networks (NYSE: JNPR) today introduced its next-generation and the industry’s fastest core routing platform that delivers breakthrough levels of performance with the new network economics necessary to support service provider business models into the next decade. Juniper Networks(R) T4000 Core Router, powered by the Junos(R) operating system, provides the scalability and flexibility required to meet rapidly expanding bandwidth requirements, while extending the unprecedented investment protection of the T Series platform, the most widely deployed core routing platform in the world.
At 240 Gbps/slot, the T4000 is the industry’s fastest and densest IP/MPLS router, built and optimized for transport networks, the service provider backbone and major peering points around the world. With four terabits of line rate throughput in a half rack chassis, the T4000 is purpose-built to facilitate the continued rapid increase in multimedia applications, including enterprise collaboration and mobile video conferencing as well as new and emerging cloud and research applications.
‘At Comcast, we are committed to delivering more and more compelling entertainment and communications experiences to our customers,’ said Kevin McElearney, vice president of network engineering at Comcast, one of the leading providers of entertainment, information and communication products and services in the United States. ‘Juniper has been an important technology partner in helping us grow and evolve our network to meet increasing customer demands, and the capabilities of Juniper’s T4000 look promising in helping us expand even further.’
The T4000 is being introduced as Internet traffic patterns are increasingly more dynamic with video, cloud computing and mobile applications placing new demands on the network. ABI Research projects that U.S. mobile data traffic will grow more than 500 percent in the next four years to reach more than 3,200 petabytes by 2014. With Internet traffic expected to increasingly include some form of video, the higher network core capacities of the T4000 will be essential to meeting subscriber expectations of reliable connectivity to rich media content.
‘Our number one priority is meeting the expectations of our customers around the world as our core network experiences year-over-year growth,’ said Kempei Fukuda, senior director, Global Business Division, NTT Communications Corporation, a global leader in delivering broadband communications. ‘With the demand for 100G approaching, the capabilities of Juniper’s T4000 would help us deliver the reliable bandwidth our customers require.’
T4000 Extends Unmatched History of Investment Protection
The T4000 extends Juniper’s history of flexibility, performance and investment protection by enabling existing T640 and T1600 core routers to be upgraded to T4000 without service disruption or changing customer-facing interfaces. All generations of the T Series have multichassis capability built into the architecture and support the same consistent Junos operating system deployed in every one of the top 100 service providers worldwide.
‘Juniper is the clear leader in innovative, next-generation networking technologies, including being the first to announce and deliver 100G,’ said Stefan Dyckerhoff, executive vice president and general manager, Infrastructure Products Group, Juniper Networks. ‘With the T4000, Juniper is now the first to provide clear investment protection for three generations of core routers since the introduction of the T640 more than eight years ago.’

这篇报道没写出来啥，看来还是得首席等人分析一下有啥新的东西。
如果说做得更快了，就这一点是对半专业人士可能更感兴趣的东西。但是很多业内人士可能更想看看别的东西。比如是否对整个网络的架构啊啥的有真正的update。
我想是应该有的，只不过看来记者没写出来。
aban3rd 于 2010-11-16 1:07 上午
这个发布信，感觉有中兴的风格，只讲大容量，没有讲具体的发布时间，够虚的！！
不知道T4000和中兴T8000是什么关系
asr1k 于 2010-11-16 1:39 上午
我记得讲了的啊 2011 2H
asr1k 于 2010-11-16 1:43 上午
反正大概也就是这样了， LC上用了Trio的套片 ， 然后Fabric的Chip从F16又升级了一下频率。 机箱没换大改不可能， 到2011 2H发布的主要原因很有可能是高频率下Matrix机箱的链接可能有问题。

100G就是亮点。asr1k是怎么分析出来的？频率升级一下就行，有这么简单吗？结构不变，升级频率，更高性能，chip厂商的日子这么好过？

好像没有看到40G和100G的接口板卡？

The T4000 will support a diversity of interfaces, optimized to deliver the benefits of 10/40/100GE. In addition to supporting all existing T640 and T1600 interfaces, the new interface cards include:
12×10GE
1×100GE with CFP
2×40GE with CFP
The T4000 will be showcased in a live demonstration at the Supercomputing conference in New Orleans, November 15-19. The T4000 will be available in 2H 2011.

哎呀, 实在是抱歉.下午一边开会一边打字有些快了没说清楚. 仔细说说吧:
我们注意到以前的T640的架构, 首先看Fabric是4:1. 那么T4k应该是1T的单块SIB. T640 到 T1600是采用多块混合加提升频率构成的. 而T4k的亮点很有可能是一块单chip 1T的 16×16的crossbar ASIC. 这是其一.
其次是Linecard, 我们注意到Linecard都是半高的(以前有全高或者1/4高), 也就是说FPC上可以同时插两个PIC. 某种意义上来说很有可能是4块 Trio分别提供两个 120Gbps的PIC支持. Trio的优点其实也是很明显的, 原有的结构上I-chip / scheduler /Q and memory ASIC需要多块chip完成的活已经让 Trio搞定了. 所以多搞几块trio套片是蛮正常的. 因为某种意义来看, J不可能在Trio后短时间流片另一块chip. 复用Trio也很好的继承了原有的架构.
接口卡可能有两种, 一种是40/100G的卡, 另一种是10个10G的接口卡.
至于难点, 可能还是要说说Matrix机箱了. J是CLOS架构.也就是说可能需要到明年2H release的主要原因是因为 CLOS架构的FCC机箱ASIC还在diag或者还有什么问题.
最后, 为啥要今天发布这个消息呢. 因为CRS3今天正式FCS.
大致汇报完毕, 很粗糙, 欢迎J家出来指正错误:)
