From fiscal 2024, digital textbooks and digital teaching materials will be fully introduced at schools. Accordingly, there are concerns that when multiple learners access digital content all at once, the internet connection will be overloaded and the connection will be delayed. For this reason, we have prepared an edge cache function-equipped model that can temporarily save (cache) digital content on “Tbridge®” and reduce internet traffic.

Content acquired from distribution servers for digital textbooks, etc., is temporarily stored (cached) on “Tbridge®”. When a learner accesses the same content, it is processed on the intranet (within the school) by the cache, which reduces the load on the internet line (external line). This creates a stable environment for using digital content, including digital textbooks.
