“SBCSession Border Controller

The Session Border Controller provides a mature, proven carrier grade technology packed with feature rich capabilities allowing operators to rapidly deploy services. A flexible licensing model allows clients to meet budget requirements and scale as and when future growth dictates.

At the heart of the SBC lies a core set of features including web based OA&M. 

Flexible licensing provides the choice of Legacy SS7, Next Generation SIGTRAN or 4G/IMS/LTE network support.

 

Session Border Controller Security

 
TICKSecurity:
 
DoS/DDoS Protection
Allow trusted/authenticated users access while under DoS attack   
Dynamically accept or reject traffic based on device behaviour
Throttling and overload protection 
 
TICK Access Control:
Control of max concurrent sessions
Filter devices/networks on a per application basis
Permit access to known devices or networks
Authorise/deny access for registered users; permit or deny access mask users
Accept media only for authorised sessions 
 

TICK Topology:

Hide network topology preventing direct attacks and maintain privacy
Mask user information for privacy and confidentiality
 
 
TICK VPN Support:
 
Secure L2 and L3 VPN customers
Support inter-VPN sessions
IPSEC encryption levels, DES, 3DES, AES
PPTP - PPP (PAP or CHAP), 40, 126bit MPPE
L2TP 
 
 
TICK Fraud Prevention:
 
Perform signalling and media validation by authenticating and authorising users

Redundancy

SBC redundant architecture


TICK 1+1 Dual Plan Worker / Hot Standby
TICK Database and signalling information checkpointed between planes
TICK Replicated hardware and software
TICK Maintain SIP calls in answer on failover
TICK Eliminates single points of failure
TICK Five Nines Uptime (99.999%)
TICK Single IP service address using VIP technology
TICK Real time maintenance upgrades
TICK RTP Failover and Re-Invite

Capacity Growth

For a capacity of more than 10,000 simultaneous calls we offer a distributed architecture model for the SVI_SBC.

The advantages of this model:
TICK Virtualisation of Signalling and Media Planes
TICK Centralised Signalling Plane
      TICK Lower Processor usage support up to 30,000 simultaneous calls
      TICK Can be located in Cloud
TICK Distributed Media Plane
      TICK High processor usage
      TICK Add in additional media planes where and when needed
      TICK Distribute across territories providing shortest path media connections
