Isocore Validates Alcatel-Lucent's Service Router

Isocore has tested and verified the Alcatel-Lucent 7750 Service Router (SR) as a Broadband Network Gateway (BNG) for Residential Service Delivery. Isocore tested the Alcatel-Lucent 7750 SR BNG functionality, including subscriber management, IPv6, video quality assurance and terabit forwarding capabilities necessary to deliver rich streaming video content that consumers demand from their broadband service providers.


Specifically, the test bed mirrored a deployable network comprised of two Alcatel-Lucent 7750 SRs configured as BNGs and another two 7750 SRs configured as a core node (supporting LTS) and an Internet gateway node (supporting LNS) respectively. This configuration is typical of a service provider offering both retail and wholesale Internet services. Using external linkIxia test solutions, 250,000 stateful subscriber hosts were emulated using a mixture of PPPoE and DHCP-based subscriber management protocols. A mixture of routed and bridged residential gateways were configured along with a mixture of IPv4 (with CG-NAT), IPv6 and dual stack (IPv4 and IPv6) address models. This configuration is typical of a service provider supporting customers at various stages of legacy and next generation technologies.


Hierarchical quality of service was used for all subscribers to simulate tiered service offerings. Application assurance was enabled on one BNG by emulating 125,000 IPTV STBs that collectively generated 4,000 requests per second for FCC and RET. The other BNG was configured with PerfectStream delivering 700 video channels by monitoring and selecting video packets between active and backup flows. Forced control plane switch-overs were trigger throughout the tests to demonstrate high availability and non-stop service delivery. This configuration is typical of a service provider delivering the highest quality of experience.
