re: Juniper's GGSN Gamble?Ericsson recently signed a wide ranging agreement with Huawei technologies, the chinese router giant. it seems that ericsson is hedging its bets by having an alternative router vendor, in case its alliance with Juniper ends. That could spell some trouble for Juniper as not only Huawei's routers sell for a fractions of Juniper's cost, but combined with Ericsson's dominant position in the wireless space, they could be a force to reckon with..
re: Juniper's GGSN Gamble?Actually, the recent Ericsson Huawei deal was primarily about ERICY licensing Mobile technology to Hauwei - it wasn't about ERICY reselling Huawei gear (although that may be a possible scenario down the road).
re: Juniper's GGSN Gamble?Does Huawei has a wireless router ? To my knowledge not yet they are working on it. The other company in China that may have one by now is ZTE. These guys (ZTE) are a pomping machine of new products, im not sure if they work well thow . Does anybody have any info on them (ZTE) ?
re: Juniper's GGSN Gamble?In GPRS there are two types of GPRS Support Nodes (GSNs) that are part of the core data network. The SGSN (Serving GSN) is the link from the Base Station Subsystem (BTS and BSC combined) to the GPRS intermediate IP backbone and the GGSN (Gateway GSN) is the other side of the intermediate IP network that connects the mobile environment to a standard IP network, e.g. the Internet.
The difference between these products and normal IP routers is the fact that they must support several new, higher layer protocols, as well as handle the mobile aspect of the user. In practice, this means support for the GTP (Gateway Tunneling Protocol) between SGSN and GGSN and the SS7 links to the mobile databases that control the flow of traffic as the mobile user moves from region to region (or maybe even cell to cell) within the GSM/GPRS network.
Many of the SGSN/GGSN products on the market today are based upon standard router products that have been modified to encompass these new protocols, e.g. Nortel's is based upon the Passport platform. Cisco also has offerings in this area, as well as Ericsson, Nokia and all the other major GPRS players, of course.
Most good GPRS references on the web have the requisite diagrams and more detailed explanations ..... although it can a little hairy if you don't understand the wireless/SS7 part of the network.
re: Juniper's GGSN Gamble?> With LR posting more and more about mobile, > shouldn't it change its name as well to > MobileReading?
Speaking about name change, it seems to me that F---ed Industry will be more appropriate.
Also, it seems to me that LR Index found some support around 100, does it make sense to recalibrate back to 1000 now to better reflect on market moves in the sector ?
Don't need to, as LR already owns Unstrung (http://www.unstrung.com) - a dedicated wireless site, which might explain why you're seeing a tad more mobile/wireless stuff on LR.
re: Juniper's GGSN Gamble? An SGSN is more akin to a layer 2 switch that uses IP for transport whereas a GGSN is more akin to a RAS device...which makes me wonder why JNPR would try to make a GGSN from a core routing platform (J20/M20) instead of their recent acquisition of B-RAS technology through Unisphere.
