VoIP Foundation—Advanced QoS and
Bandwidth Management
Advanced QoS—enforce or change traffic priority based on port,VLAN,
t
source MAC,ACL,802.1p,Type of Service (ToS),or DiffServ settings
to prioritize business-critical flows
Ultra-low Latency—industry-leading port-to-port latency of 10 to
t
20 microseconds for superior call quality when using VoIP and other
latency-sensitive traffic such as video
Multiple Queuing Methods—Strict Priority (SP) or Weighted Fair
t
Queuing (WFQ) provides flexibility for network administrators in
enforcing traffic prioritization
Scalable Multicast Implementation
Comprehensive Multicast Feature Set—hardware-based multicast
t
features allow network managers to efficiently deploy streaming media
applications for improved employee collaboration and productivity
Diverse Multicast Protocol Support—IGMP ,DVMRP ,MSDP ,
t
PIM-SM (Sparse Mode),and PIM-DM (Dense Mode) give administrators
the flexibility of supporting a variety of applications with complete
interoperability to existing applications
Superior Multicast Scalability and Performance—Up to 64,000
t
Layer 2 Multicast groups with sub-second join and leave latency for
industry-leading multicast performance and scalability
Cohesive, Unified and Easy-To-Use
Network Management
Centralized Network Management—Foundry's IronView Network
t
Manager
™
is a web-based,graphical interface tool (GUI) that empowers
network operators to seamlessly control software and configuration updates
for any Foundry product from a central station.This dramatically
simplifies network provisioning,diagnostics and resolution,thus reducing
the operational expenses.
MRP—Managed Rim Protocol for the Enterprise rapidly reconfigures
t
for network changes that affect the local ring,and with no need for
network-wide reconvergence.This results in dramatically improved performance.
Command Line Interface (CLI)—is an industry-standard
t
configuration interface,consistent and common throughout Foundry's
entire product portfolio
Web Interface—provides easy to use Graphical User Interface
t
for system configuration from standard Web browsers
sFLow (RFC 3176)—provides scalable,ASIC-based,wire-speed
t
network monitoring and accounting with no impact on network
performance.This allows network operators to gather a variety of
sophisticated network statistics and information for capacity planning
and real-time network monitoring purposes.
IronShield
Security
™
Wire-speed Extended Access Control Lists (ACL)—control packet
t
forwarding and restrict access to the system management interface,while
providing wire-speed switching and routing:
— Feature-Rich ACL Implementation—identify traffic based on
source or destination IP address,IP protocol type,TCP or UDP port,
IP precedence,or TOS values
— Selective ACL Logging—collect statistics for packets matching the
deny or permit conditions
— ACL Scalability—support for up to 4,096 ACLs
— Ease of Administration—identify an ACL by name or number,
or add a comment line for ease of administration
— ACL Syntax Compatibility—uniform ACL syntax across all
Foundry products provides compatibility with syntax of other
major vendors
Wire-speed, fine-grain Bandwidth Management—Traffic classification
t
and bandwidth enforcement based on port,port plus priority,or Layer 4
ACLs,from 1 Mbps up to 1 Gbps in increments as small as 256 Kbps
MAC access control using either MAC registration or IEE802.1x allows
t
for controlling unauthorized or untrusted hosts from accessing the network.
Applying dynamically configured VLANs and Layer 2 filters,or Layer
3/4 ACLs further secures the access.Tunneling a link between host client
and a centralized policy server over the 802.1x EAP protcol allows for a
thorough analysis of the host to ensure it is in a trusted state prior to going
access to the network.
Secure Shell and Secure Copy—provide secure access to the
t
administration and management interface over the network
Protection Against Denial Of Service (DoS) Attacks—prevents or
t
minimizes network downtime and protects against malicious users by
limiting TCP SYN and ICMP traffic and protects against broadcast
storms by limiting broadcast traffic
User Authentication—authentication with AAA,802.1x,RADIUS,
t
TACACS,and TACACS+ to prevent unauthorized network access
Wire-speed Rate Limiting—enforce bandwidth policies to prevent
t
unauthorized network hogging
SFlow (RFC 3176)—provides cost-effective,scalable,wire-speed
t
network monitoring to detect unusual network activity
SNMPv3—Secured SNMP management with RFC 2570 through
t
2575,provides User-Based Security model (RFC 2574) for authentication
and privacy services
Industry Leading Performance
Industry's Highest Switching Performance—non-blocking,distributed
t
switching architecture with a parallel cross-point switch fabric provides up
to 480 Gbps of aggregate switching capacity,and 178 million packets per
second switching performance
State-of-the-art TCAM—provides wire-speed Layer 2/3 switching
t
and policy based routing with industry leading switching capacity
and scalability
Jumbo Frames—support for jumbo frames on Gigabit and 10 Gigabit
t
interfaces allows dramatic scalability in server throughput while
minimizing the impact on server processing resources
