PPT《河南省教育科研网运行汇报》

河南省教育科研网运行汇报 河南 郑州大学2003-08-08 目录河南省教育科研网发展运行情况汇总网络服务 HERNET的发展 HERNET一期建设 入网高校47所,前期绝大多数学校和地市以2M接入建设高速骨干城市节点7个,全部2.

5G连接,并局部构成环路,在网络层上实现线路冗余利用2.5GPOS和EDFA技术实现远距离(最远洛阳-郑州180公里)IP数据传输以千兆/百兆光纤方式接入当地教育城域网的学校逐步达到37所全省出口流量增长至300兆以上,国际流量也大幅度增加 HERNET二期主干网 HERNET二期建设 新增高速城市节点9个,全部以2.5G 互联,并在全省范围内构成四个路由环路,保障骨干网络的畅通全省入网高校达到61所,其中有多所合并高校提供所有地市入网单位1000兆的接入能力全省范围年内开通组播服务,实现更广泛的多媒体资源共享全面推动河南省高校数字化校园的建设 典型网络结构 省主干网 城市节点骨干网交换机 城市节点接入产品 入网高校 网络运行情况(全省出口流量) 网络运行情况(全省至武汉出口流量) 城市节点流量分布(新乡) 城市节点流量分布(周口) 接入高校流量分布(郑州航空管理学院) 郑州市城域网流量分布(教育厅节点) 网络异常时流量表现(病毒及网络侵入造成进出流量不均衡) 网络故障统计 网络故障主要由以上三种组成,另由CERNET主干线路故障引起的网络中断有三次 网络故障统计 2002年7月1日-2003年7月1日,累计发生网络故障15次,累计时间44小时,所统计的故障都是影响到至少一所接入高校,甚至一个接入地市的,各接入单位内部原因引起的故障未计入在内. 主干网络路由(OSPF) E2 202.196.236.64 [110/20] via 210.43.146.18, 00:35:45, POS4/0 [110/20] via 210.43.146.22, 00:35:45, POS6/0O E2 202.196.236.32 [110/20] via 210.43.146.18, 00:35:45, POS4/0 [110/20] via 210.43.146.22, 00:35:45, POS6/0O E2 202.196.236.0 [110/20] via 210.43.146.18, 00:35:45, POS4/0 [110/20] via 210.43.146.22, 00:35:45, POS6/0O IA 210.43.26.0/24 [110/15] via 210.43.146.26, 00:35:45, POS3/0 210.43.147.0/24 is variably subnetted,
