河南省教育科研网运行汇报

1、河南省教育科研网运行汇报河南 郑州大学2003-08-08目录目录 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

2、，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省主干网城市节点骨干网交换机城市节点骨干网交换机城市节点接入产品城市节点接入产品入网高校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CERNE

3、T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
