BCM5840

Gigabit Security Processor

The BCM5840, the world's first single chip Gigabit security processor, removes barriers to providing efficient, wire-speed security across an entire LAN or WAN network infrastructure at multi-Gigabit data rates. Broadcom's latest security processor sustains throughputs of 2.4 Gbps for wirespeed IPsec encryption and authentication, regardless of packet size. The BCM5840 provides breakthrough performance, until now, unavailable in commercial products, thereby enabling ubiquitous wirespeed security in routers, firewalls, switches and accesses servers at data rates up to full-duplex OC48 (4.8 Gbps) using a BCM5840 in each direction.

The innovative BCM5840 sustains multi-Gigabit performance for 3DES-CBC and HMAC-SHA-1 or HMAC-MD5 IPsec processing. The unprecedented performance levels of the BCM5840 are quickening the pace at which the Internet, in the form of virtual private networks (VPN), is replacing expensive, dedicated networks for remote access to corporate Intranets and business-to-business transactions.
