Despite a negative GDP report coming in at -0.3% to begin that start of the recession, stocks actually spent most of the day in the black. The Treasury has finally started paying TARP funds out to large banks, and the second tier banks are next in line. Oil is contained, and an old and haggard looking T. Boone Pickens gave an interview this morning saying he was out of oil but thinks oil will go back to $100.00 next year.

The Brocade Communications (NASDAQ: BRCD) deal is interesting for a couple reasons. First of all -- hey it's a deal. So yes, deals can still get done, even in this market.

Second, and more importantly, BRCD is paying $3 billion or almost exactly three times the cash and investments on Foundry Networks' (NASDAQ: FDRY) books. So in essence, 1/3 of the deal price is being funded by the liquidity of Foundry Networks balance sheet. Looking at the technology landscape, there are a whole bunch of companies that look like FDRY from a balance sheet perspective.

Also, this deal highlights the fact that even in a market full of angst, companies do look forward to see what business trends they want to exploit. My take is BRCD is seeing it wants a bigger part of the bandwidth pie going forward and the two companies may have complementary technology to help extend their current reach.

Foundry Networks, Inc. (NASDAQ: FDRY), which builds networking technologies, went public in 1999. With the Internet surge, the stock price went over $200.

Of course, that was a temporary thing. Since then, Foundry's shareholders have suffered.

However, this week they got some cheery news. Foundry agreed to sell out to Brocade (NASDAQ: BRCD). The deal comes to about $2.91 billion in a combination of cash and stock.

Essentially, the deal blends some key technologies. While Brocade has a strong footprint in fiber channel systems, Foundry is a top player in switches and 10-gigabit Ethernet offerings.

If anything, it's a necessary step to deal with the intensely competitive environment, especially against the mighty Cisco (NASDAQ: CSCO).

No doubt, Brocade has demonstrated success with M&A, such as with its acquisition of McData. However, networking deals can be tricky. After all, Brocade operates primarily on an OEM basis whereas Foundry has a large direct sales force.

There is some financial risk too as Brocade needs to borrow about $1.4 billion.
