Thank u for ur reference. But I think there should also be some wireless telecom tech and I think it is very important, while Cisco's document someone recommanded is quite old. By the way, any one had idea of Cisco's C&S CCIE track? Is it a replacement of the old WAN or something? How about Juniper's JNCIE? Thank u all again By the way, I'd check the book list of both Cisco and Juniper. Some of them are the same. The unfortune is I can't find all of them in China bookstores.
