IPSec DES and 3DES Encryption • Ensure confidential data integrity and authenticity of origin by using
standards-based encryption
• Provide encryption for all users on the LAN without configuring individual PCs
• Encryption available on a single WAN devices allows users to access IP aware
devices such as print servers, IP phones, etc, where as encryption initiated
with PC software clients prevents access to those devices
Cisco Easy VPN Remote • Easy deployment and maintenance of VPN connections with auto-IPSec
tunnel initiation and pushed policy acceptance
Multiuser IPSec Pass-through • Allows IPSec tunnels to pass through the router when VPN PC Software
clients are required
• Support for PPTP tunnels, encrypted or unencrypted, initiated at the PC
PAP, CHAP, and ACLs • Protects network from unauthorized access
Route and Router • Accepts routing table updates from only known routers, ensuring that no
corrupt information from unknown sources is received
NAT/PAT • Hides internal IP address from external networks
• Prevents certain denial-of-service attacks from outside networks on internal
hosts
Integrated Toll-Quality Voice/Data
Four Analog Telephone (FXS)
Interfaces
• Provides toll-quality, award-winning derived VoIP; software-upgradable to
VoATM/AAL2 (Q3 CY’01)
Standards-Based H.323 (H.225)
Signaling
• Allows an ecosystem of third-party vendors to develop applications for a
complete solution; allows rapid low-cost deployment of VoIP
DSPs and Voice-Compression
Codecs G.711, G.729, G.723.1
• Provides hardware-based compressed voice to fit significantly more voice
lines over a single copper-pair without breaking the end-to-end delay budget
Differentiated Classes of Service
IP QoS LLQ, Weighted Random
Early Detection
• Ensures consistent response times for multiple applications by intelligently
allocating bandwidth
• Allows for classification of applications and gives the most important
applications priority use of the WAN line
• Provides congestion avoidance by telling certain TCP sessions depending on
priority to throttle down
• Provides QoS admission control and end-to-end management of bandwidth
reservation and allocation
ATM Traffic UBR, VBRnrt, VBRrt,
and CBR with per-VC Queuing
and Traffic Shaping
• Ensures QoS guarantees for real-time traffic, with ability to send traffic over
the appropriate virtual circuit to provide ATM level shaping andensure thatno
head-of-line blocking can happen between circuits of different or equal traffic
classes
Choice of Encapsulation (PPP
over ATM, PPP over Ethernet and
RFC 1483 (RFC 2684)
• Ensures compatibility with existing network
