KDDI Flexible Private Leased Circuit Service

Recommended for companies requiring a low-latency and bandwidth-guaranteed network for business communication between corporate facilities, such as a link between headquarters and data center!

Overview & Features

KDDI Flexible Private Leased Circuit Service is a bandwidth-guaranteed network service utilizing MPLS-TP (Multi Protocol Label Switching - Transport Profile) technology.
MPLS-TP technology expands label switching using the conventional MPLS and offers quality and functionality equivalent to the existing Private Leased Circuit service by combining routing control and high-quality OAM function [1].
With a wide variety of bandwidth menus, flexible interface menus that even allow for the use of the existing telecommunication devices, and access multiplexing option that integrates multipoint communications, this high-quality and highly-reliable KDDI Flexible Private Leased Circuit Service enables the construction of a large-scale PLC network.
