An Efficient Addressing Scheme for Flexible IP Address

Along with the popularization and adoption of IP in various emerging scenarios, challenges also arise with the ossified address structures. The reason is that conventional IP address is designed with fixed length and lacking extensibility, while the demand for IP varies greatly in different scenarios. Flexible IP (FlexIP), as a variable-length IP address, proactively makes address structure flexible enough to adapt to various network cases and solves the problem of low transmission efficiency faced by current IP addresses. However, due to the variable length of FlexIP, the conventional routing addressing scheme is not suitable for it. In this paper, we propose a new Bloom filter addressing scheme suitable for FlexIP address. We use controllable prefix extension to limit the prefix distribution of FlexIP, and use one-hashing to improve the computational overhead of the Bloom filter. Simulations show that the addressing scheme we proposed is more suitable for FlexIP than other schemes, and has better query efficiency.
