摘　　要：多链路用户自由选择问题是多链路校园网设计的难点之一。结合PPPoE(PPP over Ether-net)和VLAN(Virtual Local Area Network)设计实现的黑龙江大学校园网络,在拥有CERNET和CNUNINET双上行链路的情况下,实现了上行链路的自由选择,同时也满足了对用户管理和计费的相应要求。此设计的成功为高校校园网多上行链路环境下的网络设计开拓了思路,具有一定的参考价值。How to choice different up links freely for users is one of difficulties in campus network design in the condition of many up links. Integrating PPPoE（PPP over Ethemet） and VLAN （Virtual Local Area Network） into Heilongjiang university campus network has realized the up link free choice on the situation of holding CERNET and CNUNINET pair of up links, at the same time has also satisfied the user management and network costing request . This design proposal can expand the way of thinking for designing the university campus network with many up links environment, it has the certain reference value.
