Net-Net Session Director
(SD)
High-performance, high-capacity session border
controller integrates signaling and media control
using back-to-back session agent architecture for
SIP, H.323 and MGCP
Security
–
Access control including signaling-controlled
media pinhole firewall
–
Network topology hiding – NAPT at layers 3 (L3)
and 5 (L5)
–
Customer/supplier hiding – route stripping
–
DoS protection – L3 IP attacks, L5
attacks/overloads including
signaling rate limiting
Service reach maximization
–
Hosted NAT traversal including distributed media
release
–
VPN bridging/interworking overlapping address
spaces via VLANs including RFC 2547 MPLS VPNs
–
Interworking – static and policy-based SIP-H.323
and H.323-H.323 versions and configurations, SIP
RFC 3261-2543, SIP UDP-TCP signaling, DMTF in-and
out-of-band (RFC 2833), T.38 fax
–
Translations – address/number, error messages
SLA assurance
– Session
admission control – bandwidth constraints, session
agent signaling constraints and/or observed QoS
–
L2 and L3 QoS marking/mapping – IEEE 802.1p and q
(VLAN),
ToS, DiffServ, MPLS
–
QoS reporting – SLA reporting, problem alerting
and isolation,
session auditing, admission control
Revenue and profit assurance
– Service
theft protection – bandwidth policing, CODEC
stripping, signaling-controlled QoS
marking/mapping for QoS theft protection
– Softswitch
scalability – redirect support, load balancing and
failover, UDP-TCP SIP signaling interworking
–
Accounting – real-time RADIUS CDRs with QoS
metrics, session
timers
Law enforcement and regulatory compliance
–
Lawful intercept – intercept access point – call
data and/or call
content; intercept access point anonymizer
–
Emergency (E911) services support
High performance, availability, capacity,
manageability
– Performance
– 5 Gbps packet filtering, 15 microseconds media
latency, 5-10 milliseconds signaling latency, over
100 call set-ups per second
– High
availability – active/standby systems, media and
signaling state check-pointing – no loss of active
calls or call state required for session handling
(transfer, hold, etc.), NAT traversal and accurate
CDR generation, in-service software and
configuration upgrades
– Capacity
– up to 32,000 concurrent sessions, up to 2 Gbps
bandwidth
via (8) 10/100 or (2 or 4) 1000 Mbps Ethernet
interfaces
– Manageability – CLI, EMS, XML, SNMP, syslog,
telnet
Net-Net Session Router (SR)
High-performance SIP and H.323 routing engine
selects optimum border point or session agent
Rich policy and network constraint-based routing
–
Net-Net SD, softswitch, application server load,
etc.
–
Source/destination URI/telephone number or realm
–
Cost, time, media profile, service provider
preference
–
Telephone Routing over IP (TRIP) (RFC 3219)
dynamic route
exchange
–
ENUM service for telephone number:SIP URI
resolution
–
Accounting – real-time RADIUS CDRs, session timers
High performance, manageability
–
CLI, EMS, XML, SNMP, syslog, telnet
Net-Net SR functionality
is also available on Net-Net SD.
Net-Net PAC
Performance, Availability, Capacity
PACk of up to nine 1U Net-Net session border
controllers performs as one logical session border
controller, scales to industry-leading
performance, availability and capacity in only 9U
of rack space
Performance
–
Up to 900 call set-ups per second (CSPS),
equivalent to 3.24
million busy hour call attempts (BHCA)
–
Up to 400 calls per second (CPS) – typical SIP
seven message call flow including call set-up and
tear-down
Availability
–
Five nines design using active/standby systems
–
Media and signaling state check-pointing – no loss
of active calls or call state required for session
handling (transfer, hold, etc.), NAT traversal and
accurate CDR generation
–
In-service software and configuration upgrades and
Net-Net PAC
expansion/contraction
Capacity
–
Single or multiple signaling interface per PAC,
network or subscriber group 256,000 concurrent
sessions
–
1024 VLANs for customer/subscriber segregation
including VPN
support
–
800K endpoint registrations, 256K hosted NAT
traversal registrations
–
16 Gbps bandwidth
Manageability
–
EMS, XML, SNMP, syslog, telnet, CLI
