Comcast has finally started its rollout of Docsis 3.0 in the northwest. Comcast will be offering this service in Seattle, Spokane, and surrounding areas in Washington, and Eugene in Oregon. How about the subscription cost? I must say that Comcast haas lived to its standards, it is extremely pricey. Here are the subscription costs I got from an article in Lightreading:For its initial wideband

Arista Networks released a joint whitepaper with Intel on 10 GigE performance technologies and penetration of 10 Gig Ethernet into SANs using the iSCSI protocol. The whitepaper is available here. The whitepaper discusses a bunch of Intel technologies for 10 GigE such as I/O Acceleration Technology (IOAT) and Virtual Machine Data Queues (VMDq). Also mentioned is how iSCSI is helping 10 GigE

Neterion has an excellent whitepaper on IOQoS, a technology that enables multiple virtual channels to have independent QoS parameters while sharing the same Neterion 1- GigE adapter. OpenSolaris has a similar project, Crossbow which lets virtual streams have independent QoS parameters while sharing the same 10 GigE interface.

According to a Lightreading report, Telcordia is trying to bring optical security at 100 Gbps using Photonic Layer Security (PLS). PLS changes an optical signals' phase by different amounts at different points, and then applying a similar iteration on a combined optical signal. That mixes things up, but the number of phase changes involved is small enough to be cracked by trying enough possible

Here is an interesrting article from Google about our need to reduce the dependence on ISPs to deploy advanced fiber based broadband access services such as PONs. This coincides with Google chief Internet evangelist Vint Cerf criticizing ISPs for not deploying PON like infrastructure in the US (See article here). Google has also bought considerable mobile spectrum recently sold in the US. These

Brocade announced yesterday its intent to buy Foundry networks for $3 billion, a considerable premium over Foundry's current market cap. This deal is interesting in a variety of ways, but it definitely points towards the importance of Ethernet, particularly Fiber Channel over Ethernet (FCoE) in the future. And in many ways it could be the turning point of the ethernet revolution in the data

PMC-Sierra has released a white paper on their 10 Gig reference design. While the paper does not talk about much technical details on 10 GigE, it does try to motivate 10 GigE the obvious way, IPTV. It talks about the growing demand for HDTV, and how people with multiple set top boxes would require bandwidth that can be provided by 10 GigE solutions. Nothing much new, but may be interesting read

Fiber Channel over Ethernet (FCoE) is a technology which aims at I/O consolidation over Ethernet (mainly 10 Gig Ethernet) by encapsulating Fiber Channel frames over Ethernet. FCoE's success will ensure 10 Gig Ethernet's penetration into the Storage Area Network (SAN) market which has been till now mainly dominated by Fiber Channel and iSCSI. The main challenges to FCoE are (i) Encapsulating Fiber

Three days ago, Comcast announced that it is reversing its policy of blocking peer to peer (P2P) traffic selectively during peek hours of traffic. Although Comcast had never announced this as a stated policy, numerous studies in last year or two had showed P2P performing substantially poor over Comcast compared to competing ISPs. So the question of Internet neutrality has become an immensely

Intel today released open source code for encapsulating Fiber Channel packets in Ethernet Frames which can be then transported over 10 Gig Ethernet. The software designed for linux is available on Open-FCoE.org. I expect that this will bring in more 10 Gig Ethernet stuff in SANs and data center environments where Fiber Channel has been pretty dominant till now.

Although I do not follow hot chips, and have never blogged about microprocessors, I would love to talk about Sun's UltraSparc T2 launched last week, the first microprocessor ever to support an integrated network I/O support. Yes, UltraSparc T2 which I would prefer to call by its moniker Niagara 2, supports multithreaded dual 10 Gig Ethernet. From product brochures, this chip seems to be a true

With the advent of 10 Gig Ethernet, network I/O has become unbelievably fast. This poses substantial challenges for kernel designers, because the erstwhile thinking that I/O is not CPU intensive does not apply any more. With 10 GigE, you can easily exhaust all the CPU in your box just transmitting or receiving raw packets without doing anything substantial.This poses an interesting dillema, (i)

LightReading has an interesting article here on Meriton's plans for a new technology called Carrier Ethernet Transport (CET). The idea is to switch Gigabit Ethernet tunnels directly on the WDM layer instead of doing it a layer 3. The article talks about end-to-end Ethernet delivered via backbone networks and the Ethernet PON. If anyone has some more insights into this technology please post a

This is an interesting article at Lightreading reporting cable companies facing a bandwidth crunch. This is not unexpected, since residential broadband bandwidth consumption is increasing rapidly, particularly downloaded video traffic, such as from YouTube. Moreover, the data channels available in DOCSIS 2.0 are limited, DOCSIS 3.0 will still take some time to deploy.What I found more
