In brief: AT&T and Cisco expand relationship

AT&T and Cisco last week announced an expanded marketing and sales relationship. The companies are working to roll out AT&T's managed data services to customers in the U.S. The companies also will team up on product and technology planning for managed service offerings.

They are collaborating on selling 17 AT&T services, including IP VPN, IP network security, metropolitan optical, metropolitan Ethernet, managed router, managed hosting and voice and data integration services.

BellSouth's Wavelength Service, unveiled last week, offers enterprise customers in BellSouth territory high-speed point-to-point connections. The service is BellSouth's first offering based on Dense Wavelength Division Multiplexing. DWDM uses light beams to create multiple transmission paths on one copper strand. Each beam can support speeds up to 2.5G bit/sec. WaveLength Service will be available throughout BellSouth's Southeast region.

Products that support the IEEE's 802.11i pending wireless LAN security specification likely will not ship for another 12 months, according to an Intel network architect working on the standard.

The 802.11i specification is designed to plug all known security holes in the IEEE's 802.11b wireless LAN specification that also is known as Wi-Fi. The 802.11i specification will include a system for creating fresh keys at the start of each session. It also is expected to provide a way of checking packets to make sure they are part of a current session and not repeated packets that a hacker might use. But in the meantime, wireless experts say users still shoulduse Wired Equivalent Privacy to keep wireless LANs as secure as possible.
