Academic Computing and Communications CenterOﬃce of Educational Cloud
The Oﬃce of Educational Cloud has been established forthe purpose of promoting e-learning at the university andimproving the quality of education through ICT. Its main work
is operating the learning management system (LMS) for theentire university. Furthermore, in an aim to expand educational materials focused on videos that provide better educational

beneﬁts than text-based educational materials that have beenused up until now, the Oﬃce is introducing systems such as aremote lecture and automatic recording lecture system while
producing and distributing various multi-media contents. Inaddition, the Oﬃce operates TSUKUBA Open Course Ware(OCW) programs as a means to externally communicate theuniversityʼ s education and research activities. The Oﬃce of
Educational Cloud serves as the cloud infrastructure thatSpeciﬁcally, the Oﬃce is engaged in the following projects:
1.

Operating the learning management system for the entire
university
2. Constructing an educational cloud system
3. Developing a remote lecture and automatic recording lecture system
4. Supporting the expansion of video educational materials
through coordination between the video distribution
server and LMS
5. Operating TSUKUBA OCW

Academic Computing and Communications Center was established in 2004 by merging Educational
Media Center and Science Information Processing Center, both of which had been in operation since thefoundation of University of Tsukuba. In 2007, the center was restructured to be included in Organization
for Information Infrastructure, which organization is in direct supervision to the university head oﬃce andthe Vice President in charge of the information strategy of the university.
Academic Computing and Communications Center performs R&D relating to information environments
and information services that utilize such environments, as well as maintenance, operation, and service
provision for the information infrastructure. Its main activities include:
1. Formulating information infrastructure maintenance plans
2. Maintaining, operating, and providing services for the backbone information network
3. Maintaining, operating, and providing services for the Zengaku computer network
4. Providing various services based on information infrastructure
5. Promoting environmental sophistication to education, such as with e-learning
6. Ensuring information security
These activities and the related highly-advanced research and developments were promoted by anorganization consisting of four R&D departments. In 2012, the Oﬃce of Educational Cloud was established to develop and to provide educational infrastructure, such as e-learning systems, and to promote
media contents.

１Network Research and Development Department
Network security is enhanced such as by installingﬁrewalls at on-campus and oﬀ-campus connection points andby controlling port accesses. This does not only prevent
unauthorized access at both on/oﬀ-campus. Installation ofanti-virus equipment prevents the infection and spread ofviruses via e-mail.

Network R&D Department mainly performs the following
activities and R&D related to activities in addition to operations
and management of the backbone of the on-campus network.
(1) Operation and management of on-campus backbone network,and operational support of the oﬀ-campus research network
On-campus backbone network access points such as
10gigabit Ethernet and wireless LAN networks installed incommon campus areas are operated and managed by thedepartment. It also operates, supports and connects theon-campus network with SINET6.
(2) Ensuring network security

With the recent deluge of information, information or“content” that passes through a network is being required to beappropriately handled, in addition to handling network. In orderto support such information handling from the perspective ofinformation security and information ethics, the Information
Security R&D Department implements technical countermeasures that respond to the various incidents occurring in thecampus network. This is implemented by collaboration with theother three departments of this center and the committees
related to information security such as the Incident Response
Oﬃce of the Organization for Information Infrastructure. The
department also performs education planning and awarenesseducation related to information security and information ethics
for students and staﬀ for the purpose of deterring the occurrence of incidents and to improve the morals such as in using
network and handling of information. Furthermore, the department is involved in R&D of information security technology thatenables information systems and services to be used safely.

Major department activities regarding education planning andawareness education on information security and information
ethics implemented from the past are indicated below.
1) Producing and displaying posters that indicate “P2P Usage
Prohibited on the University Network”
2) Displaying that P2P usage is prohibited on the login screenof the Zengaku-system
3) Holding seminars related to information ethics for teachersand students
4) Producing “Using Information Systems Safely and Securely,”a pamphlet (in Japanese, English, and Chinese) concerning
information ethics and distributing the pamphlet to allstudents and staﬀ5)
Adopting “INFOSS Information Ethics” e-learning materials
using manaba for new students entering colleges as part ofthe classes for the “Information” common subject and making
sure the students conduct self study

Uniﬁed Authentication System Research and Development Department
Uniﬁed Authentication System Research andDevelopment Department operates a uniﬁed
authentication system, which enables a common
password to be used for authentication in various
on-campus computer systems. Changes to common
passwords for the uniﬁed authentication system andviews of registered information can be made from theuniﬁed authentication system website. Every year
there are more and more computer systems which
use the uniﬁed authentication system. The latest list
can also be found on the website.
