Abstract
Aiming at the problem of low interconnection efficiency caused by the wide variety of data in SWIM (System-Wide Information Management) and the inconsistent data naming methods, this paper proposes a new TLC (Type-Length-Content) structure hybrid data naming scheme combined with Bloom filters. This solution can meet the uniqueness and durability requirements of SWIM data names, solve the “suffix loopholes” encountered in prefix-based route aggregation in hierarchical naming, and realize scalable and effective route state aggregation. Simulation verification results show that the hybrid naming scheme is better than prefix-based aggregation in the probability of route identification errors. In terms of search time, this scheme has increased by 17.8% and 18.2%, respectively, compared with the commonly used hierarchical and flat naming methods. Compared with the other two naming methods, scalability has increased by 19.1% and 18.4%, respectively.
Highlights
The core goal of SWIM is to promote efficient and safe information sharing between different business systems or applications of civil aviation software and hardware [1]
The hierarchical content naming scheme solves the issue of aggregations, it requires users to know the encoding rules used by the content owner or naming authority to map readable names to object identifiers (OID)
This paper proposes a new naming and aggregation scheme, in which the content identifier OID is composed of a set of variable-size information elements (IEs), and each IE is encoded as TLC (Type-Length-Content)
Summary
The core goal of SWIM is to promote efficient and safe information sharing between different business systems or applications of civil aviation software and hardware [1]. Data communication and exchange mechanisms are not timely and effective, which severely restricts the efficient sharing of civil aviation information [2] Because of these problems, it is necessary to design an applicable naming method for the business system and data of SWIM to solve its data transmission, sending and receiving, and interaction problems. The content router can flexibly control the degree of aggregation or the popularity of content objects according to the distance to achieve a balance between the required resources and the compression of routing information [8] This hybrid naming scheme is superior to prefix-based aggregation in the probability of routing discrimination errors and achieves an improvement in search time and scalability.
