  • Works with fiber-optic cabling to extend operating distances, lower electrical interference, and resist packet sniffing
  • Secures sensitive data at wire speeds - with DES/3DES encryption, MD5 and SHA-1 hashing, RFC 2402 authentication, and up to 75 Security Associations
  • Hardware-enforced security features meet FIPS 140-2 criteria; NIST approval pending
  • Supports larger packets?segments TCP frames for the Ethernet MAC and adds TCP sequence numbers to each packet
  • Uses flow control to reduce lost packets and retransmissions for more efficient data transfer between the NIC and switch
  • Responds to router-based management requests from sleep mode to help resolve IP address-aging issues
