Advantages

Cost Savings: FR offers reduction of physical local loops over private line network as frame uses a virtual circuit for each new connection
Higher circuit utilization: FR makes use of physical circuit by statistically multiplexing multiple PVCs over a single physical circuit
Higher network availability: FR network employs switches that support automatic routing of PVC around circuit failure
Extended Technology Life Duration: FR is backwards compatible with older technologies like X.25 and forward compatible with newer technologies like ATM and MPLs
Protocol Independence: Supports wide variety of application transports and meets the throughput requirements.
Performance: FR services offers higher speed with lower delay as compared to X.25

Disadvantages

44.736 Mbps data rate is not enough for protocols with higher data rates
Allows variable length frames
Create varying delays for different users
Not suitable for sending delay sensitive data such as real; time voice or video or teleconferencing.
