Connectivity Briefs: 3Com, 802.11g, Intel

New NICs from 3Com

3Com has announced network cards with embedded firewall technology and made available its previously announced secure NIC products and policy server for locking down PCs and servers. The hardware-based firewalls for 3Com's 10/100Base-T NIC could help IT security staff prevent unauthorised access to network servers or PCs from inside and outside a network. The embedded firewall on the NICs works independently of the operating system running on the host machine and can filter traffic based on IP address or virus and Trojan signatures.

802.11g adds to WLAN

Chipmaker Intersil and networking giant Cisco have announced that they are releasing a reference design, sort of a basic recipe, for building wireless network interface cards based on the draft IEEE 802.11g standard. The idea is that wireless LAN equipment vendors will take the Intersil-Cisco design, which exploits Cisco software features for wireless clients and for advanced security, to build interface cards. The cards, in various sizes, would fit into laptops, PDAs and other devices and use a radio link to connect with a wireless access point. The 802.11g area is touted as a way to help enterprises shift from current relatively slow 802.11b wireless LANs to faster nets that still operate in the same 2.4GHz band.

Intel expands GE lineup

Network managers who need fast pipes to servers, workstations and PCs will see Gigabit Ethernet become less expensive and more widely available with the introduction of three Intel Gigabit Ethernet interface chips. The vendor has unveiled a high-performance interface controller for workstations, a controller for servers that integrates two interfaces for failover and load-balancing, and a controller optimised for desktop PCs. All are single chips that control a system's communication with the network. Gigabit Ethernet, the next step up from 10/100Mbps Ethernet, offers a maximum 1000Gbps connectivity.
