An efficient multipath routing schema in multi-homing scenario based on protocol-oblivious forwarding

With the advent of 5G, multi-homing will be an increasingly common scenario, which is expected to increase transmission rates, improve transmission reliability, and reduce costs for users. However, the current routing methods are unable to fully utilize the resources of networks to achieve high-performance data transmission for multi-homed devices. In the current routing mechanism, there is only one destination address in the packet forwarded to the multi-homed host. Thus, the packet is difficult to adjust its path on the fly according to the status of the network to achieve better performance. In this paper, we present an efficient routing schema in multi-homing scenario based on protocol-oblivious forwarding (POF). In the proposed schema, the packet forwarded to the multi-homed host carries multiple destination addresses to obtain the ability of switching the transmission path; meanwhile, the router dynamically adjusts the path of the packet through the perception of the network status. Experimental results show that our schema could utilize the alternative paths properly and significantly improve the transmission efficiency.
