100Gbit/s Ethernet Router Test: Alcatel-Lucent
The 100Gbit/s architecture is of course just as much a question of the interface line card as it is of the chassis, if not more so. For the tests, Alcatel-Lucent used their 100Gig-capable version of their Integrated Media Module (IMM) cards -- one with a single 100GbE interface and one with 12 10GbE interfaces (oversubscribed). They explained that the same network processor is used in both the 100GbE IMM card and the 10GbE IMM card and both are 100Gbit/s ready. The code version running on the router throughout the tests was TiMOS-C-8.0.R9. We were told that operators who already have a 7750 SR-12 in their network can upgrade to 100GbE by only purchasing the 100GbE interface card and potentially also a new power supply. The optics used in this test were of the LR10 type, but Alcatel-Lucent explained this was based on availability and that they support LR4 CFPs in their 100GbE interface card as well.
