3:40 -- London is hot this week, as the sunshine breaks British records and Light Reading's Ethernet Expo: Europe 2007 rolls into town.

The two-day event is shaping up to be a humdinger, with keynote presentations from BT Group plc (NYSE: BT; London: BTA), Colt Technology Services Group Ltd , Extreme Networks Inc. (Nasdaq: EXTR), and the MEF , and plenty of panel representation from other carriers, including Belgacom SA (Euronext: BELG), Exponential-e Ltd. , Global Crossing (Nasdaq: GLBC), Interoute Communications Ltd. , Masergy Communications Inc. , Virgin Media Business Ltd. , Videsh Sanchar Nigam Ltd. (VSNL) (NYSE: VSL), and Yipes Enterprise Services Inc. .

Then there's the Ethernet Service Provider of the Year Awards, and the prospect of a lively discussion during Wednesday's "Hot Topic Roundtable: PBT vs MPLS/VPLS." (See European Ethernet Service Provider of the Year Finalists.)

Keep up with all the news and debate on Light Reading during the next few days.
