Example of the creation of a flexible corporate network
As organizational mergers and departmental integration become more frequent, there are bound to be more opportunities to review corporate networks. With GIGASTREAM TypeG, you can build flexible networks using redundant hub architecture (2.4G/10G ring) that does not affect lines to other offices when adding and consolidating offices or increasing speed. Of course, we offer excellent reliability through redundant end-to-end lines using different paths including access lines.
