QoS-Aware Resource Allocation for Network Virtualization in an Integrated Train Ground Communication System

Table 1

The QoS requirement of different applications in urban rail transit systems.

Number	Application	Throughput	Packet loss rate	Transmission delay	Jitter delay	Reliability
1	CBTC	100 kbps	Less than 0.005	150 ms	None	High
2	CCTV	1 Mbps	None	500 ms	30 ms	Intermediate
3	PIS	4 Mbps	None	500 ms	30 ms	Intermediate
