LINE Planet and VPN

A virtual private network (VPN) is a network that creates a secure network over an existing network that is less secure, such as the internet.

LINE Planet enables real-time voice or video communication over the internet, so network characteristics are crucial to user experience. A VPN changes network characteristics, which affects LINE Planet services in several ways.

Considerations for using a VPN

If you use LINE Planet under a VPN, check the items below.

1. Latency

VPNs cause additional latency. Latency is a crucial network characteristic for a real-time communication service. Generally speaking, the lower the latency, the better the user experience.

VPNs can also cause jitter. LINE Planet will increase latency to compensate for VPN network jitter.

2. Network bandwidth

VPN inserts additional headers into existing packets, so the size of the packets increases. The size of the additional headers varies depending on the VPN configuration.

For your reference, LINE Planet has recommended bandwidth for reasonable service quality.
