温州日报报业集团成立于2003年,集团下设日报、晚报、都市报、商报、岸望杂志社、温州新闻网、发行中心、财务中心等机构。在技术部门合并之前,各单位的信息化建设由各报、网、刊自行实施,各单位独自拥有一个独立的二层网络、独立的互联网出口和独立的私有IP地址段,互联互通极为不便。随着网络应用的不断深入和用户的不断增加,原有网络传输带宽较低、系统运行速度缓慢等问题已逐渐显现出来。因此,建立一个能解决集团内各单位互联互通问题的集团网络迫在眉睫。为此我们在日报大楼内新建了一个IDC中心机房,各分支机构与总部IDC机房之间采用两条1000M(由2家运营商提供)裸光纤进行互联;并用2台Extreme-BD 8810核心交换机、7台X450汇聚交换机、30台Summit200全三层的楼层交换机搭建了我们高性能的集团城域网,统一从总部出口到互联网;对所有电脑的IP地址进行重新分配,网络划分了VLAN,并对其权限做了很好的设置。以下就这次改造中的IP和VLAN划分、网络协议选择以及各单位间的ACL设置做一简单分析。
Wenzhou Daily Newspaper Group was established in 2003, the group consists of daily, evening, city newspaper, business newspaper, shore magazine, Wenzhou news network, distribution center, financial center and other institutions. Prior to the merger of technical departments, the informatization construction of each unit was carried out by newspapers, websites and magazines. Each unit had its own independent layer 2 network, independent internet outlet and independent private IP address segment, which made it extremely inconvenient for interconnection. With the continuous deepening of network applications and the increasing number of users, problems such as low original network transmission bandwidth and slow system operation have gradually emerged. Therefore, it is imperative to establish a group network that can solve the interconnection problems among various units in the group. To this end, we have built a new IDC center room in the daily newspaper building. Each branch office has two 1000M (provided by two operators) bare fibers for interconnection with the headquarters IDC room. Two Extreme-BD 8810 core switches, 7 X450 aggregation switch, 30 Summit200 all three floors of the floor switch built our high-performance group metropolitan area network, a unified export from the headquarters to the Internet; all the computer’s IP address to re-distribute the network VLAN, and Its permissions made a very good setting. The following transformation on the IP and VLAN division, network protocol selection and the ACL settings between the units to do a simple analysis.
