17 17 100 G link up? Challenges in setting up the testbed: Light between the two DWDM systems at Jülich and Karlsruhe Huawei developer saw light at both ends after several hours of work Installation and “booting up” of the Cisco CRS-3 Router Setting-up 100GE Interface between Cisco Routers and Huawei Transponders - preproduction CFPs - optical interfaces of one vendor - new releases will solve the vendor incompatability Bruno Hoeft -- SCC/NET 19.10.2010 07/22/2010 Time

18 18 Challenging – Interface errors Input errors increased at 100GE „KIT“ interface Standard ping (MTU 1400 Byte)  2% packet loss Error investigation result: bad input signal at Cisco CRS-3  resulting in „link flap“ After the link was stable (initially) Parameter adjustment caused “link flap” (link instable over weekend) Further adjustment at transmission system stabilised link (2 days of work) Link was stable for the duration of the testbed (3 weeks) Input error at KIT resolved and a small input error ratio at „FZJ“100GE (less than 10 -7 ) cause: old preproduction CFP at KIT First tests of testplan were executed: „Ramping up UDP load on `routing loop´” Bruno Hoeft -- SCC/NET 19.10.2010 07/23/201007/27/2010 Time
