Cisco Spotlight Series: Service with a smile
Gary Moore couldn't be prouder. During the past four years, the Cisco Systems Inc. senior vice president has transformed the networking giant's advanced services group from an organization that helps fix products to one that addresses what Cisco calls the product lifecycle. What's the difference? Now, Moore said, Cisco can help any customer with any problem â€“ whether it's products, processes or planning for the future -- better and faster than ever before. SearchNetworking.com spoke with Moore about the state of the professional services industry, how Cisco avoids stepping on its resellers' toes and whether Cisco will become the next Electronic Data Systems Corp. (EDS).
Cisco Spotlight Series: The need for speed
Despite the growth in networking segments like wireless, IP voice and application networking, what has driven the industry from its earliest days is the basic need to transport ever-growing amounts of data from one point to another. At Cisco Systems Inc., those efforts fall under the auspices of vice president and general manager John McCool's gigabit switching business unit, which includes midrange and enterprise products such as the Catalyst 4500 and recently updated 6500 switches. McCool has been a pioneer in Ethernet technology and standards for more than 20 years, and he recently spoke with SearchNetworking.com about the benefits of 10 Gigabit Ethernet, whether old cables can keep up with it and if ATM's time has truly passed.
Cisco Spotlight Series: A router for all seasons
It's no secret that Cisco Systems Inc. is betting heavily on its line of Integrated Services Routers (ISRs). Already one of the top-selling product lines in its history, the devices are built to run simultaneous services such as data, security and quality of service (QoS) at wire speed in one integrated routing platform. In an exclusive interview, Paulette Altmaier, vice president and general manager of Cisco's premises communications business unit, explains the ISR concept, how the devices can cut the cost of VoIP and why it's not risky to depend on a single platform for routing and security.
