Extending the researches on wavelength switched optical networks (WSON), efficient integration of the novel optical
packet switching network and wavelength switching-based optical circuit switching network technologies which offers
both best-effort packet delivery and QoS guaranteed lightpath services has been being studied. In addition, researches on
the optical-layer transparent data processing, such as all-optical wavelength multicasting, all-optical 3R regeneration, etc,
are conducted simultaneously. It is believed that future innovative optical network services (INSes) would be built on
these novel future-proof technologies, and foster colorful applications in the new generation networks. Before the wide
applications of INS in different fields, there would be a foreseeable strong requirement for INS firstly posed by pioneer
grid applications, e.g., e-science, e-government, and e-banking, etc, which would require the high-performance
underlying networks. Our research here is motivated to glue the optical networks and grid applications by integrating
lightpath, geographically distributed INS systems and grid resources (e.g., computers, storages, instruments, etc.), and
finally offering an easy-to-use high performance networked grid computing environment-optical grid network (OGN)
to user applications. In this paper, we introduce our research activities of a distributed optical grid network infrastructure
(OGNI), and the creation of the future easy-to-use INS based on OGNI. The proposals have been validated through fieldtrial
experiments over a developed WSON testbed.
