BRAS (Broadband Remote Access Server) is a key building block of the new generation of broadband access networks. BRAS' act as an aggregation point for subscriber traffic. It provides aggregation capabilities (e.g. IP, PPP, ATM) between the Regional/Access Network and the NSP(Network Service Provider) or ASP(Access Service Provider). Beyond aggregation, it is also the injection point for policy management and IP QoS in the Regional/Access Networks.
Validating the functionality, scalability, and reliability of BRAS is of critical concern to service providers that are rolling out broadband and “triple play” services.
The Agilent N2X provides the most comprehensive solution for testing the scalable performance of BRAS' through:.
- Industry's leading multi-protocol emulation and traffic generation environment,
- Unparalleled scalability of both control plane and data plane.
- Extensive interface coverage (from 10/100/1000 Ethernet, OC3/12 ATM to 10GE/POS).
- Patented real-time measurements,
- Powered through a versatile GUI
- Fully featured API
Versatility
BRAS' are required to handle a wide range of network protocols and QOS policies. Only Agilent N2X can comprehensively validate performance limits of BRAS'.
- Full support of access protocols, PPPoE, PPPoA, PPPoEoA, L2TP, DHCP, Stacking VLAN.
- Full support of IPV4/V6 Routing protocols, MPLS, L2/3 MPLS VPN, VPLS, IGMP and multicast routing protocols
- Complete hardware interface to accomodate the widest range of BRAS test scenarios.
- Simultaneously emulate and validate PPPoX, L2TP, Routing, MPLS, VPN and QOS through an easy to use GUI. Also emulate both unicast and multicast traffics simultaneously from the one interface.
Scalability
Only Agilent N2X, with the industry's highest layer 2/3 traffic and protocol
scalability can test the ultimate performance of the BRAS.
- Industry highest stream scalability through the generation and measurement of over 32,000 unique streams per port simultaneously. Validate:
- Over 32,000 Unique streams representing customers levels (QoS) with detailed statstics for each stream
- Over 32, 000 PPP sessions per port, 128k per module, with detailed statstics for each session
- Over 32,000 L2TP tunnels per port, 128k per module, with detailed statstics for each session
- Over 2000 BGP sessions per port
Innovation: Industry Leading solutions
N2X builds upon Agilent's long established reputation of innovation through
continuous industry leadership in test methodologies and test
capability. Agilent N2X provides the most advanced testing functions to verify the most sophisticated features of BRAS.
- PPPoE over 10GE interface
