Is Huawei ie global or national?

Different certification. This was basically the case before 2006, because Huawei and H3C were still a company at that time. Later, 3com acquired H3C, and then HP acquired H3C. Therefore, the current H3C can be regarded as the network department of HP. Huawei's data communication department certification should be level 3 in 2009, and IE is the highest level certification, which is generally for agency engineers.
