re: Juniper's GGSN Gamble? Speaking about name change, it seems to me that F---ed Industry will be more appropriate.

"Failed Industry"? :)

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 ?

Yea, let's have a reverse stock split on the LR index!

re: Juniper's GGSN Gamble? Nortel has a Passport SGSN, and Shasta for the GGSN. I believe there's also a Contivity-based GGSN, offering different features or performance.

I thought Nortel's GGSM offering was based on their Contivity product. Do they offer two types of GGSMs? If so, why?

re: Juniper's GGSN Gamble?
Belzebutt is correct - the SGSN is based on Passport, GGSN on ... etc. Also ... Nortel's PCUSN is based on the Passport platform (> holds breath and waits in anticipation of the next, somewhat obvious, question <)

re: Juniper's GGSN Gamble? PCUSN=Packet Control Unit Support Node

Performs radio functions in GPRS network, linked to the base station.

There's a taxonomy explaining how some of this stuff fits together on Unstrung.

BTW, looking into Cisco's GGSN plans. They have some mobile kit based around the 6500 series (Mobile Comms Works is it?) and Alcatel has based GGSNs on 7200 series, but they need to come out with some new product to compete w/ the startups etc.

Or maybe they'll just buy one of the start-ups.

re: Juniper's GGSN Gamble? The original work was done on the Contivity,
then moved to the Shasta product.

re: Juniper's GGSN Gamble?
Just as an FYI, some of the main links on the taxonomy page on Unstrung are 'bent' but not 'broken' .... they go to the wrong descriptor page ....

'Current' wisdom out there right now seems to be that the SGSN/GGSN product set is somewhat of a commodity (i.e. little differentiation in price or feature set), and unless you can add some significant value to the process the current crop of startups will find enormous barriers to entry in terms of ousting the radio vendors who might be prepared to give the xGSN away to get the more lucrative radio infrastructure business.

Ps. the PCU converts the data over frame relay traffic from and to the SGSN into the subrate channels that are sent to the radio system for over-the-air transmission. As part of the BSS it usually sits behind the BSC so that it can aggregate data traffic from many individual Base Stations (BTS's) in an efficient and cost-effective manner.
