310 Border Gateway - Product Specification

Benefits

See Also 1460 Performance tests PDF 310 Border Gateway Data Sheet

• The ability for SIP and H.323 controlled media to traverse corporate, consumer and core network NAPT and Firewall devices.
• Quality of Service enforcement using media session policing to prevent users from exceeding their negotiated session bandwidth.
• Border media security protecting the core network, customers, and service revenue.
• Regulatory compliance providing Lawful Intercept of media.

The 310 BG is provided in a single 4U high 19" chassis and supports from 1,000 to over 25,000 concurrent calls.

All variants support a call establishment rate of up to 140 media sessions per second.

Security

Network Address and Port Translation (NAPT) provides media address privacy and ensures connectivity to networks that use private or un-routable addressing schemes. Randomised port allocation prevents malicious media access through port scanning attacks. Policing of RTCP as well as RTP streams is performed to ensure that users only pass media traffic in their RTP stream.

Quality of Service

Media Policing prevents fraudulent or faulty sessions from exceeding agreed bandwidths, protecting the QoS of other clients. Media policing is performed per media flow within a session.  The policing policy is passed to the 310 Border Gateway from the 1460 BC or 3rd party SoftSwitch on call setup.

DiffServ Code Point (DSCP) re-marking enables media flow differentiation based on a quality policy to be enforced on a per-user and per-session basis

Carrier Grade

310 BGs are protected in two ways:

• In the case of complete 310 failure, the controlling 1460 BC or Softswitch detects the 310 failure and directs all subsequent media sessions to alternative BG media resources.  This resilience at the network level allows the operator to optimise their BG resources.
• The 310 supports physical link aggregation (802.3-2002) ensuring that failure of a link does not result in traffic loss.  Optionally the 310 BG supports link aggregation across interface cards ensuring that traffic is not lost if an interface card fails.

The 310 BG (with 1460 BC) support the secure traversal of corporate and network based firewalls and NAT devices, without deploying additional customer premise equipment or replacing existing firewalls and NAT devices.

Regulatory

The 310 Border Gateways acts as part of a Lawful Intercept solution providing media interception.  When used in conjunction with a 1460 BC, a turnkey Lawful Intercept solution can be provided intercepting all required signalling and media paths and providing Handover Interfaces that are fully compliant with local regulatory requirements.

Standards

The Newport Networks 310 BGs are future proof and comply with the architectural requirements of the 3GPP IMS and ETSI TISPAN standards. At the subscriber edge of the core network, the 310 BG provides the TISPAN Access to Core Border Gateway Function (A/C-BGF) capabilities. At interconnect points, the 310 BG provides the TISPAN Interconnect Border Gateway Function (I-BGF).
