Table 6 Comparison of the two options to implement tunnels between MCE and WCE for mobility support as depicted in Figure 11

From: A novel network architecture for train-to-wayside communication with quality of service over heterogeneous wireless networks

 

Option 1

Option 2 (preferred)

Tunnel socket per

Service Class

Network interface

Scheduling by

Tunneling protocol

Scheduler module

Links per Multiple active socket

links (multi-path)

One link + back-up links (multi-homing)

Contention per link

Yes

Only during link failure

Data traffc fow over multiple links

Yes (risk for jitter)

No

Protocol suggestions

MP-TCP

SCTP

 

MMP-SCTP
