an incorrect inbound interface; and helps prevents source spoofing and distributed attacks
IPSec VPN:
supports DES, 3DES, and AES 128/192/256 encryption as well as MD5 and SHA-1 authentication
DVPN:
collects, maintains, and distributes dynamic public addresses through the VPN Address Management (VAM) protocol,
making the VPN establishment available between enterprise branches that use dynamic addresses to access the public
network; compared to traditional VPN technologies, the DVPN technology is more flexible and has richer features, such as
NAT traversal of DVPN packets, AAA identity authentication, IPSec protection of data packets, and multiple VPN domains
Convergence
Internet Group Management Protocol (IGMP)
utilizes Any-Source Multicast (ASM) or Source-Specific Multicast (SSM) to manage IPv4 multicast networks; supports
IGMPv1, v2, and v3
Protocol Independent Multicast (PIM)
defines modes of Internet IPv4 and IPv6 multicasting to allow one-to-many and many-to-many transmission of
information; supports PIM Dense Mode (DM), Sparse Mode (SM), and Source-Specific Mode (SSM)
Multicast Source Discovery Protocol (MSDP)
allows multiple PIM-SM domains to interoperate; is used for inter-domain multicast applications
Multicast Border Gateway Protocol (MBGP)
allows multicast traffic to be forwarded across BGP networks and kept separate from unicast traffic
Internet Group Management Protocol (IGMP) snooping and proxy
o monitors and observes IGMP network traffic, allowing the network device to listen in on the IGMP conversation
between hosts and routers—enabling better IP multicast stream control
o allows a multicast router to learn multicast group membership information; and enables it to forward multicast
packets
Multicast VPN and bidirectional protocol independent-multicasting (PIM)
o allows rich multicast services such as video conferencing and data sharing amongst enterprise VPN-based
deployments
o improves scalability of various applications through the use of bidirectional PIM
Integration
Embedded NetStream
improves traffic distribution using powerful scheduling algorithms, including Layer 4 to 7 services; monitors the health
status of servers and firewalls
Embedded VPN firewall
o provides enhanced stateful packet inspection and filtering
o delivers advanced VPN services with Triple DES (3DES) and Advanced Encryption Standard (AES) encryption at
high performance and low latency
o offers Web content filtering and application prioritization and enhancement
Additional information
Green initiative support
provides support for RoHS and WEEE regulations
OPEX savings
simplifies and streamlines deployment, management, and training through the use of a common operating system,
thereby cutting costs as well as reducing the risk of human errors associated with having to manage multiple operating
systems across different platforms and network layers
Faster time to market
allows new and custom features to be brought rapidly to market through engineering efficiencies, delivering better initial
and ongoing stability
