Campus network
 Hokkaido University’s campus network known as HINES (Hokkaido University Information NEtwork System) is an important information base for research, education and support activities. Sapporo Campus has an ultra-high-speed core network, which connects the southern, central and northern areas and is linked with five departmental nodes, as well as the departmental nodes of Hakodate Campus. This core network is structured using multi-protocol label switching (MPLS) and links approximately 33,000 machines to HINES via a number of connecting devices. Hokkaido University is also interconnected with Science Information NETwork 4 (SINET4) as one of its node universities, enabling high-speed domestic and international connections.

Security of HINES
 HINES has introduced security systems to improve the safety and reliability of the entire campus network from both software and hardware aspects, including those for protection against illegal access/attacks from the outside, checking for viruses in all e-mails received and sent and monitoring access to the node rooms. VPN connection has also been introduced to allow the use of HINES from facilities in remote areas.

HINES services
 HINES provides the following network services.
● HINES mail
 The service provides e-mail addresses and 20GB mailboxes on request by users, and is IMAP compatible. It also provides a mailing list service.
● Virus checker/spam mail filtering
 E-mails received and sent are checked constantly to determine the presence of viruses and infected ones are removed. Spam mails from within and outside the university are also filtered by an original HINES method.
● Intrusion prevention system
 A defense system has been introduced to protect the network from unauthorized access, intrusion and destructive attacks from the inside and outside. Monitoring of P2P software is also performed to prevent information leakage.
● Vulnerability examination system
 To prepare for unforeseen circumstances, there is a system to examine the presence/absence of security holes and vulnerability of devices linked to HINES.
● Wireless LAN system in shared spaces
 A wireless LAN system has been introduced in shared spaces on campus, including the Conference Hall and Multimedia Education Building. The university has also joined the International Academic Wireless Roaming Network (eduroam) for use by visitors from other universities and countries.
