The nCite� SE and nCite� DE high
performance Session Controllers were designed and tested in
partnership with the world's leading IP Communications
carriers and independent third party labs to ensure the
product meets or exceeds the functional and operational
requirements of service providers worldwide.
These session border controllers resolve the peering,
latency, quality of service, capacity and control issues
preventing widespread commercial deployment of VoIP. The
session border controller is a transparent addition to
existing VoIP networks that enables carriers and service
providers to fully realize PSTN parity - resulting in a
reduction of costs and increased revenue through the
interconnection of VoIP islands. Several current market
drivers point to the increasing demand for IP services that
can only become a reality with native IP interconnection.
VoIP networks are typically built as "island networks" due
to complexities associated with IP interconnection or
peering (such as address overlap and security firewalls).
The lack of scalability in current VoIP deployments is
compounded by the lack of performance parity with the
PSTN.Many indicators include: the tremendous growth of IP
PBXs and the adoption of VoIP and SIP-based products. As the
nCite session controllers enter the market, they will
support three main applications areas for wireline and
wireless networks:
Residential
Carrier to Carrier Peering
Enterprise
Security
Hardware based DoS protection- Deep packet classification
Performs intrusion prevention by detecting and blocking
overflow buffer attacks. CERT Advisory CA-2003-06 test suite
for SIP signaling vulnerabilities
Rogue RTP Detection
Ease of Management
Fully redundant solution purpose-built for carrier market
Reduces VoIP network complexity with a single, compact
system that replaces multiple point solutions
Carrier-Class Redundancy/Reliability
Media Anchoring
Media anchoring configurable on a virtual proxy basis
Modify signaling traffic to accommodate NAT/NAPT
Session Admission Control Solution
Provide a virtual line count for a customer
Bandwidth management and policing
Apply QoS metrics to calls that exceed the virtual line
count
Session Detail Record Solution
Provide start/stop records for both signaling and bearer
traffic
Provide key performance indicators of voice bearer traffic
(latency, jitter, loss)
Interconnection
Carrier to Carrier, Enterprise to Carrier, Residential to
Carrier
nCite is the most cost effective VoIP interconnection,
reducing the need for PRIs
The result is the market leader in carrier-class
performance. Netrake manages from 1,000 to 42,000
simultaneous calls (dependent on codec), with full
redundancy, (in stateless proxy mode or up to 120 calls per
second in stateful proxy mode). In addition the Element
Management System (EMS) leads the market in operational
control, provisioning and management.
The nCite Session Controllers Deliver:
Unmatched Scalability - nCite is designed to more than
satisfy the requirements generated by any economic model,
from small to very large. nCite call capacity ranges from
1,000 simultaneous sessions up to 42,000 simultaneous
sessions, all in a single compact system.
Unequaled Support - nCite reduces infrastructure
requirements by replacing multiple point solutions with a
single, integrated (signaling and media) solution and
reduces VoIP network complexities
Reduces operations costs
Leverages existing investments in networks and back office
systems
High Availability and Reliability - Fully redundant
hardware and software architecture for system processor,
switching fabric and I/O modules ensures no loss of calls
and highest quality of reliability.
Ease of Management - Deployment of nCite Session Controllers
does not require modifications and/or special configurations
to existing network infrastructure including; routers,
gateways, gatekeeper capabilities, or security systems.
