Alcatel-Lucent Tests 100GE Performance with Isocore and Ixia

Isocore has tested and verified the Alcatel-Lucent 7750 Service Router's (SR) 100 Gigabit Ethernet (100 GE) performance using Ixia's K2 100 GE test solution. The tests validate the Service Router's ability to handle high-touch service connections at 100 Gbps line-rate speeds. The companies said the test results also demonstrate the viability of 100 GE for broad deployment throughout carrier networks, extending beyond the IP core and into the service edge and metro, where services meet the network.

This test is the first 100 GE demonstration of line-rate, loss-less transmission using a diverse mix of service traffic types with thousands of queues and service attributes, which are critical for service assurance. Ixia's K2 and IxNetwork were used to emulate the Ethernet and IP traffic seen on business VPN services offered to corporate customers who have stringent performance and service level agreement (SLA) expectations.

Specifically, Isocore and Ixia tested configurations that emulated large-scale connection and service attributes in service provider networks which offer high-touch IP and Ethernet VPN services. Isocore used Ixia's K2 100 GE test solution to transmit, capture and perform real-time analysis with full line-rate 100 GE Internet mix (IMIX) traffic in conjunction with layer 3 Virtual Private Networks (L3VPN), layer 2 VPNs, QinQ double tagging at the customer edge, and Ethernet Virtual Private LAN Services (VPLS).

The test emulated both customer edge (CE) and provider edge (PE) routers with OSPF (Open Shortest Path First), LDP (Label Distribution Protocol) and MP-iBGP (multiprotocol-Interior Border Gateway Protocol) sessions. The Alcatel-Lucent 7750 SR was configured with 8,000 IP-VPNs, 4,000 Virtual Private LAN Service (VPLS) links, and 20,000 layer 2 VPNs. The 7750 SR maintained comprehensive quality of service (QoS) on each flow while operating at 100 Gbps line rate.

Ixia noted that its Higher Speed Ethernet (HSE) solutions are the only full-production test products available today that validate IEEE 802.3ba standards-based network elements. Ixia's K2 modules generate and analyze 40 GE and 100 GE BERT and layer 2-7 line-rate traffic, with up to one million distinct flows. K2 modules are compatible with Ixia's testing applications, which allowed Isocore to initially develop its configurations using 10 GE interfaces and then to quickly adapt as needed to support Alcatel-Lucent's 100 Gbps service routing interfaces.
