Huawei Replaces AlcaLu at Sunrise
Huawei Technologies Co. Ltd. has struck a five-year managed services deal with Swiss operator sunrise , taking over a role previously held by Alcatel-Lucent (NYSE: ALU).Huawei has been named as the sole managed services provider for sunrise's fixed and mobile networks. An unspecified number of staff will transfer to Huawei from sunrise and from the operator's "previous technology partner," which is AlcaLu.Sunrise originally struck a seven-year managed services deal with AlcaLu in 2008, but, under new private equity ownership and with an aggressive broadband services strategy in place, the operator terminated that contract in August 2011, with the deal coming to an end in February this year. (See TDC Sells Swiss Sunrise for $3.2B and Euronews: Sun Sets on AlcaLu's Sunrise Deal .)In April this year, sunrise announced a major fixed and mobile network modernization plan, with Huawei as its technology partner, and introduced a network quality program called TQ Net (Top Quality Network). From September, Huawei will operate and maintain the networks, with sunrise retaining strategic network planning and customer care responsibilities.Sunrise has more than 2.1 million mobile customers, giving it a mobile market share of 24.1 percent, and 369,000 fixed broadband customers. The operator generated first-quarter revenues of 509.3 million Swiss francs (US$530 million).Why this matters Huawei may be having a tough time politically in Europe, but it's getting ever stronger as a partner to the region's operators and as a rival to the incumbent vendors -- AlcaLu, Ericsson AB (Nasdaq: ERIC) and Nokia Siemens Networks .Those three European vendors have strong, experienced professional services businesses, but this deal shows that Huawei is making ground even in this sector.The big question now is whether sunrise and Orange SA (Orange Switzerland) will finally merge and whether Huawei will also become the dominant equipment and services supplier at that operator too.
Comcast: More IPv6 Traffic Please
World IPv6 Launch Day reached the halfway point Wednesday without any cataclysmic problems, but Comcast Corp. (Nasdaq: CMCSA, CMCSK) wouldn't mind seeing a few more v6 bits traveling on the network."From my point of view, I'd like to see a lot more traffic," says John Brzozowski, a Comcast distinguished engineer and the operator's chief architect for IPv6, told Light Reading Cable earlier today.Comcast has already v6-enabled sites such as xfinity.comcast.net and xfinitytv.comcast.net. "We think there's a pretty significant opportunity to increase the numbers for other kinds of off-network content from the Googles, Yahoos and Facebooks of the world," Brzozowski adds.Among ISPs, Comcast has been among the most aggressive with IPv6, so it's understandable that it would like to see how its work holds up under more stress. It's launched v6 to about one third of its broadband network, which would equate to about 6 million users, if they all had the capability turned on. In reality, about 5 percent of Comcast's high-speed Internet subscriber base has been able to use the new addressing scheme "out of the box," Brzozowski says.To beef up those numbers, he'd like the ISP community and the consumer electronics industry to work together so home networking equipment and other connected devices for the home support IPv6 by default.Although Brzozowski would like to see more IPv6 traffic, the numbers are increasing. Comcast hasn't published any specific numbers yet, but Brzozowski says v6 traffic was up 25 percent at the half-day point Wednesday. "What we want to see right now is a 24-hour cycle period of time go by and then we'll have a better read on usage patterns," he adds. "But I think there's more to come there as we go toward the end of this day."And, so far, the day has been "largely uneventful, which is certainly what we had expected," Brzozowski says. (See IPv6 Launch Day: Should Milestones Be Boring?)Looking ahead, Comcast expects to complete its IPv6 deployment on Arris Group Inc. (Nasdaq: ARRS) cable modem termination systems (CMTSs) this summer, and begin further work on the Cisco Systems Inc. (Nasdaq: CSCO) platform, work that will likely spill into next year. "Our expectation is that we'll have some nationwide [IPv6] capabilities in the 2013 time frame," the Comcast engineer adds.Wi-Fi meets IPv6 So far, Comcast's IPv6 activities have centered on its wireline broadband platform, but it's also been active with on-the-go Wi-Fi access, which has become a key component of Comcast's voice and cable modem services and is also central to a new roaming deal between several major U.S. MSOs. (See Cable Goes Big With Wi-Fi Roaming and Comcast Gives Wi-Fi a Voice .)Comcast hasn't enabled v6 on its Wi-Fi hot spot deployments yet, but at The Cable Show in Boston last month, the operator, in conjunction with Alcatel-Lucent (NYSE: ALU) and Ericsson AB (Nasdaq: ERIC), did demonstrate Wi-Fi services with native IPv6/IPv4 dual stack capabilities at the show's "Imagine Park" area. Here's what Brzozowski had to say about that.
Docsis Flirts With 5Gbit/s
While Docsis vendors work on refreshing the technology to reach 10Gbit/s downstream speeds, a recent field trial shows that current gear can get almost halfway there.Ahead of next week's ANGA Cable Show in Cologne, Kabel Deutschland GmbH and Arris Group Inc. (Nasdaq: ARRS) demonstrated downstream speeds of 4.7Gbit/s on live Docsis 3.0 plant connected to a school in Schwerin, Germany.It's considered a new Docsis land speed record, achieved by bonding 96 8MHz-wide EuroDocsis channels (that's 768MHz total spectrum). The trial used 12 Arris cable modems, each capable of bonding eight downstream channels (the latest generation of Docsis 3.0 modems can bond up to 24). (See Intel's New Docsis 3.0 Chip Guns for 1-Gig .)To complete the kluge setup, Arris and the operator inserted a Layer 2/3 switch and aggregated and multiplexed those 96 channels into a 10Gbit/s feed linked to a PC. Out on the network, the trial was fed by Arris's flagship CMTS, the C4, which was outfitted with four 24-downstream port line cards (plus one upstream card with 12 ports for good measure).Some good timing also played a part. KD and Arris conducted the trial just as the operator was about to open up a new fiber node, so there was no other traffic running on that portion of the recently upgraded 862MHz plant. "For a short window of time, they (KD) saw an opportunity to try something," says Arris CTO Tom Cloonan.The 4.7Gbit/s demo isn't anything near practical, but it does show what the current equipment generation can do. "We think this is just the starting point," Cloonan says, noting that cable modems capable of bonding 32 or 48 channels could be the next possible step, and maybe 64 after that.The road to Docsis 4.0?Converting most or all of cable's spectrum into one giant Docsis IP pipe is the sort of thing that Arris, Cisco Systems Inc. (Nasdaq: CSCO) and Motorola Mobility Inc. (NYSE: MMI) are proposing with a next-generation Docsis that they claim could support 10Gibt/s downstream and 2Gbit/s upstream. But with the number of tweaks and additions on the table, such as spectrum upgrades to possibly 1.7GHz, it amounts to a quantum leap for the technology. (See Does Docsis Have a 10-Gig Future? )Other ideas aim for nitty-gritty efficiency boosts, squeezing out more bits per Hertz. For example, the Docsis vendors are keen on OFDM (orthogonal frequency-division multiplexing), a modulation scheme already popular in mobile world, that would essentially take today's 6MHz channels (for North American Docsis) or 8MHz channels (for EuroDocsis) and chop them up into much narrower, 10KHz-wide channels. The thinking is that the smaller widths would let cable operators utilize noisy pockets that are otherwise unusable.Another idea being pushed is low density parity-check (LDPC), a new forward-error correction flavor that would aid data transmissions in noisy plant conditions by reducing the amount of bandwidth overhead required for the current technique, called Reed-Solomon. The combo of LDPC and OFDM could improve spectral efficiency by 18 percent to 24 percent, some believe.Docsis vs. EPoC Those techniques are also being considered for EPON Protocol Over Coax (EPoC), an emerging Institute of Electrical and Electronics Engineers Inc. (IEEE) standard that some view as a competitor to a next-generation Docsis platform. (See Huawei Looks Beyond Docsis.)"There's not a reason to pick one over the other in terms of performance; they're virtually identical," Cloonan says. "But cable will need to look at it from other attributes, other than performance."Cloonan says backwards compatibility is one area where a next-gen Docsis platform would have an edge over EPoC. Of course, Arris, like Cisco and Motorola, has other good reasons to favor Docsis -- they own the bulk of the CMTS market and have some sizable turf to protect.But Cloonan doesn't completely discount EPoC as a long-term option. EPoC, he said, could serve as a "stepping stone" for cable's eventual move to fiber-to-the-home, "if MSOs want to prepare for a 2030 timeframe."Still, Docsis might also be made to play a role in that FTTP transition. In one possible scenario, a new version of Docsis could be paired with Radio Frequency Over Glass (RFoG), a cable industry standard that lets operators pull fiber to the premises while preserving their headends, backoffice and provisioning systems, and cable modems and set-tops.Cloonan believes most cable operators will go with a next-gen Docsis system "if it's defined." That's still an open question, as CableLabs has yet to make any decisions about what comes after Docsis 3.0. (See The Docsis Addendum and Costs Could Keep RFoG a Niche Player .)And those decisions may depend on geography. Cable operators in China and India are already using Ethernet-over-coax technologies to serve high-density areas, so a standard like EPoC could cater to those markets, says Infonetics Research Inc. analyst Jeff Heynen.Heynen does agree that EPoC makes sense as an FTTP transition technology for cable but still thinks Docsis will reign for the foreseeable future. "We're at least ten years away from Docsis exhaust," he says. "And maybe that's conservative."
