Course Internship Report

1 Purpose of Probation

L train our students in communication engineering to work in a variety of basic skills and hands-on abilities.

L Consolidate and apply the knowledge of communication principles we have learned, and carefully observe, analyze and solve the common campus network troubleshooting methods and team discussion cooperation ability.

L Training theory with practice, from the reality, the use of computer communication to immediately analyze problems, research problems and problem-solving ability.

L Cultivate the work style of loving labor, not taking pains, not fearing tired.

2 Trainee Content

L Understand the history of the campus network

The first phase of the project from 1997 onwards, a total investment of more than 1 million yuan, connecting the school five teaching, office buildings, networking nodes more than 200, the backbone network bandwidth of 100M, export speed 64k;2000 years later completed the third teaching building and art building access, The number of networked nodes increased to more than 300, and the export speed increased to 2M.

Phase II ,2002 began implementation, October 2003 Network Center moved to a site-the Prime Minister building, this phase of the project completed the Jishou three campus interconnection, the main speed reached the gigabit, hundred trillion to the desktop;

the third phase of the project is the Zhangjiajie Campus network construction, began construction in June 2006, investment of about 2.7 million, Zhangjiajie campus at 1000M speed to connect to Jishou headquarters.

The fourth issue is mainly for the 2013 central finance to support local university construction projects, a total investment of 5.5 million yuan, this phase of the project mainly completed the campus network backbone network Gigabit upgrade and the main public areas of the campus wireless coverage.

The present situation of campus network --Network topology

L The current situation of campus network --daily operation and maintenance

The present situation of campus network --Desktop virtualization

L Digital /Smart Campus

3 Apprenticeship Process

From the beginning, the teacher introduced the campus network is a broadband multimedia network which provides teaching, scientific research and comprehensive information service for the school teachers and students. First, the campus network should provide advanced information-based teaching environment for school teaching and scientific research. This requires: Campus network is a broadband , with interactive functions and a strong local area network. Multimedia teaching software development platform, multimedia demonstration Classroom, teacher preparation system, electronic reading room and teaching, examination database, etc., can be run on the network. If a school includes more than one discipline (or multiple departments), it can also form multiple local networks and be wired or wirelessly connected. Secondly, the campus network should have educational, administrative and general management functions.

Then we explain the campus network failures we often encounter:

For example: Authentication failed, indicating "the maximum number of connections has been reached"

Cause: The account may be stolen (or the account is logged in to the school's wireless system is not retired).

For example: Unable to authenticate, prompt "Nic not Connected"

Cause: Network cable Connection is not accurate, the network cable quality is poor, or the switch is not working

Wait a minute...

Finally, the teacher explained to us the campus network machine room equipment, for example HUAWEI8512 is a core switch that can be accessed only by administrators, and allows administrators to partition the entire courtyard VLAN. Then took us to the computer room practice visit.

4 Completing the Task

1) Understand the history of the campus network

2) Current situation of campus network

1. Network topology
2. Daily operation and Maintenance
3. Virtualization of

3) Digital/Smart Campus

4) The development trend of campus network

5 Internship Experience

in the campus network of online probation, so I know the composition of the campus network and know the computer can not access the Internet roughly what is the possibility: System IP settings, network cards, line failures, and so on. At the same time through the teacher to the school network topology explanation, learned a lot of knowledge, this for our communications engineering students after graduation work closely related.

In the field visit Campus Network room when I found a lot of equipment we have never met, this shows that we learn theoretical knowledge at the same time should also step up our practical learning, we are led by the teacher to visit the campus network room equipment, while the teacher also actively for us to explain the questions we ask. This internship thanks to teacher Li, the teacher's careful planning, so that we know more about the status of the communications industry, but also aroused our love of communications professionals!
