My name is . Today I am applying for the position of network engineer in your company. After graduating from high school, I was not admitted to the ideal university, but I am very interested in computer network, so I came to Beida Jade Bird Huateng Center to learn the skill of network engineer. During the study period, I got the certificate of information system Expert and the certificate of osta Network Engineer from the Ministry of Labor.
During my study in Peking University Jade Bird Huateng Center, I was responsible for the project of rebuilding enterprise network of Beijing Zhongso Network Technology Co., LTD. The adsl mode adopted by several branches of the company has low bandwidth and unstable data transmission, which makes it difficult to realize data synchronization. Companies transmit business-related data over the internet, and financial data is quite insecure; The Intranet of the company is completely exposed to the internet, and no network security devices are installed. Therefore, it is easy to be attacked by hackers, causing huge losses to the company.
Our solution is to configure vlan and ip address planning; Let the firewall filter the traffic; stp and hsrp technologies realize traffic load sharing and device redundancy. The Ethernet channel design can improve the reliability and stability of the network. qos design ensures priority transmission of important data; ospf route planning, fast convergence without loops, and load balancing among multiple links. To enhance network security, configure nat address translation on asa and aaa services such as ssh. Configure ipsec and ssl to implement secure data transmission in different regions.
