Technical geek driven-> backed by big firms, OSS running more like

company in a more professional way

Trend5：De-facto Standard

DSO -> OSS+DSO, another fight field for standardization

Trend1：Number Exploding

Open source as a tool to tackle technology challenges

• Software is exploding in #LOC. Impossible and unnecessary to re-invent and make a wheel, where to put resources to CONTROLL external code efficiently, how to spend minimal on commoditized software while invest in differentiations…

• 1998，one Huawei switch product has 100K LOC, a GSM MSC stack has 300K LOC;

• 2007，software switch in Huawei product is about3.34M LOC;

• 2011年，a BSP for Huawei mobile SoC is 34M LOC

• But a developer can still only write 30-50 LOC/day

• OSS as a platform to cooperate

• In 3GPP era, SDO is the way for cooperation;

concept->product takes years；

• Nowadays，IT: code is far ahead of standard; CT: code is interworking with and even driving standard;
