Computer and printer giant Hewlett Packard (HP) has announced that it has acquired 3Com, a provider of computer network equipment, for $2.7 billion in a deal that is being widely viewed as an assault on networking market leader Cisco Systems. Networking is a rapidly growing market, currently worth around $40 billion each year and dominated by Cisco, which thus far has come up against very little competition. Palo Alto, California-based HP wants to use the acquisition to strengthen its position in the networking and data center sector.
