SINET3 has five service categories: transfer layer, secure (VPN), quarity-of-service(QoS), bandwidth-on-demand(BoD), and network performance monitoring.

 Comparison of SINET/Super-SINET and SINET3

Multiple Layer Services

SINET3 is an integrated network providing all transfer layer services. Users can freely choose the best transfer layer for their applications. SINET3 enables economical service provision and flexible network resource assingnment for everchanging and unpredictable service demands.

Multiple VPN Services

A closed user group environment (virtual private network: VPN) is essential for ensuring the security of collaborative research. Users can choose from L3VPN(IP), L2VPN/VPLS(Ethernet), and L1VPN.

Multiple QoS Services

SINET3 provides QoS by identifying applications, VPNs, and physical/logical ports. Layer-2/3-based QoS has four priority classes: expedited forwarding(EF), network control(NC), assureed forwarding (AF), and best effort(BE). Layer-1-based QoS has the smallest packet delay, no delay variance, and no packet loss.

Bandwidth-on-demand(BoD) Services

SINET3 provides bandwidth-on-demand(BoD) services on layer-1. Users can specify destination, duration, bandwidth with a granularity of 150Mbps, and route option. The BoD server receives reservation requests, schedules accepted reservations, and triggers layer-1 path setup.

Network Performance Monitoring Service

SINET3 will give users network information, such as backbone traffic and delay. Access to this information should help to improve usability and facillitate network research.
