“…Later work extended the analysis to periodic transactions (groups of messages with offsets) again providing both exact and sufficient schedulability tests [73]. More recent works have investigated robust [34], [37] and extensible [57] priority and message ID assignments for CAN.…”

“…• Extensibility: As shown in [57], the simple analysis facilitates the use of a priority ordering and an initial message ID assignment that maximizes extensibility in terms of future upgrades, i.e., the addition of further messages without having to change the IDs of the existing messages or the software on the other nodes.…”

While academia favours general research that is applicable to a large class of systems, this paper highlights the necessity of research into specific scenarios and aims to increase its acceptance in the real-time systems community. We argue that such research is not only motivated by greater applicability to industry, but that specialization can also provide valuable information from a purely academic perspective. In addition, the trade-offs between generalization and specialization are examined, considering not only theoretical performance, but also the impact on essential non-functional properties that are important for industry, namely composability, robustness, extensibility, and parametric simplicity.• Special Cases: When are special cases useful? Why is the exploration of special cases important and valuable?• General Cases: When are general cases useful? What should be considered when evaluating the quality of solutions and analyses for general cases? We motivate, and provide evidence for, a series of observations that distil the key differences between a focus on special rather than 1 This work covers a broad spectrum of topics related to real-time systems. We assume that the reader is familiar with basic concepts from the realtime systems literature, and therefore, to increase the reading flow, we do not introduce them in detail. Less common concepts and terminology related to a specific sub-problem are introduced in the appropriate section of the paper.

“…most able to accommodate additional messages; however, this is not necessarily the case [23]. Recent work in this area [24] provides an extensibility metric for CAN, and a message ID assignment which optimizes extensibility by assigning IDs according to ID-bands, aligned with timing requirements.…”

Many of the processors used in automotive Electronic Control Units (ECUs) are resource constrained due to the cost pressures of volume production; they have relatively low clock speeds and limited memory. Controller Area Network (CAN) is used to connect the various ECUs; however, the broadcast nature of CAN means that every message transmitted on the network can potentially cause additional processing load on the receiving nodes, whether the message is relevant to that ECU or not. Hardware ilters can reduce or even eliminate this unnecessary load by iltering out messages that are not needed by the ECU. Filtering is done on the message IDs which are primarily used to identify the contents of the message and its priority. In this paper, we consider the problem of selecting ilter conigurations to minimize the load due to undesired messages. We show that the general problem is NP-complete. We therefore propose and evaluate an approach based on Simulated Annealing. We show that this approach inds near-optimal ilter conigurations for the interesting case where there are more desired messages than available ilters.

“…In this context, Cossentino et al [7] estimated modularity and extensibility of "holonic multi agent systems (HMAS)" which is used for the development of software systems that are frequently designed in order to realize complex dynamical behavior for solving complicated problems. Pölzlbauer et al [8] addressed message ID assignment, in a manner that the system can be extensible. In the beginning, they gave an assessment metric that provides a deep insight view of the extensibility of a given ID assignment.…”

Measure extendibility/extensibility quality attribute using object oriented design metric

Software design is one of the very important phases of the software engineering. The costs of software can be minimized if improvements or corrections made during this stage. Several of the current computer aided software engineering (CASE) tools like enterprise architect (EA) v12 do not have the capability to improve the design. This work aims to develop an algorithm that helps the software engineers evaluating the design quality utilizing one of the object-oriented (OO) design models namely quality metrics for object-oriented design (QMOOD) which represents as hierarchical model that describes the relationship between quality attributes such as reusability, extendibility and properties of the design of OO design. This algorithm describesed how the assessment of the extendibility/ extensibility using the software metrics has been done and the impact of the involved metrics in the extendibility value. Results obtained demonstrate the effect of OO design metrics such as inheritance, polymorphism, abstraction and coupling in quality characteristics like extensibility. The results show that lower values of abstraction and coupling, obtain higher value of extendibility which means the class diagram is ready to accept additional improvements. The proposed algorithm has been tested on two different systems (test cases) that vary in their class diagrams, functionalities, and complexities.
