Cisco ICS 7750 System Description
78-10360-02
• External data security—IPSec tunneling with DES and 3DES encryption
provide standards-based data privacy, integrity, and authenticity as data
travels through a public network.
• Remote access security—For remote access VPNs, L2F and L2TP combine
with IPSec encryption to provide a secure multiprotocol solution (for IP, IPX,
and AppleTalk traffic). Mobile users can dial in to a service provider’s local
POP. Data is tunneled (or encapsulated inside a second protocol such as IPSec
or L2TP) back to the ASI81 to securely access the corporate network via the
Internet.
• QoS capabilities—RSVP, WFQ, CAR, and IP precedence enable businesses
to prioritize traffic on their networks by user, application, traffic type, and
other parameters, to ensure that business-critical data and delay-sensitive
voice receive appropriate priority.
• Robust voice compression—Up to six voice calls can occupy a single 64-KB
data channel simultaneously, without compromising data performance.
Cisco IOS voice-compression technology integrates data and voice traffic to
enable efficient use of existing data networks.
• High-performance RISC architecture—Supports VPN applications with
tunneling and security, and DSL, cable, and other broadband access
technologies.
