While hard network slicing with strict isolation is a promising candidate for addressing such requirements, it might be overly restrictive and hard to scale, hence leading to an inefficient use of available resources. In contrast, soft slicing can help balancing isolation and determinism by allowing a configurable degree of resource sharing between slices. In this work, we follow a simulation-driven approach to study and quantify the trade-offs between variable isolation and the degree of delay-related determinism in a single-hop environment with multiple applications. The results from this scenario will serve as a foundation towards assessing the end-to-end problem.","PeriodicalId":294749,"journal":{"name":"Proceedings of the ACM SIGCOMM Workshop on Future of Internet Routing & Addressing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133418242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Questions of which the anser may help us in understanding if the evolution of the edge will subsume the Internet itself, marking the rise of a new communication infrastructure with different properties? Or will the Internet exist and prosper as an essential foundation for other network architectures and applications?.","PeriodicalId":294749,"journal":{"name":"Proceedings of the ACM SIGCOMM Workshop on Future of Internet Routing & Addressing","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123846393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three areas are proposed as areas to be studied and developed. First, bringing the application compiler/runtime environment and the distribution orchestrator closer together such that they can share information of namespaces and mapping to lower level addressing. This would allow greater flexibility in application development and much greater optimisation of the distribution at runtime. Second, developing semantic routing as a layered framework based on information understood within a layer and information transparent to a layer. This allows semantic routing to be introduced in an evolutionary fashion. Third, embracing private networking as a primary construct of future Internet routing and addressing. This meets many practical requirements including security. The second and third also give a framework where the current widespread use of L4 and L7 switching in microservices frameworks can be clearly understood and the role they play fully incorporated for in future Internet routing and addressing.","PeriodicalId":294749,"journal":{"name":"Proceedings of the ACM SIGCOMM Workshop on Future of Internet Routing & Addressing","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123497349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a new system, Acila, to classify packets based on the identity of a workload at network devices, by marking packets with necessary information extracted from the identity that is usually stored in cloud controllers. We implement Acila and show that packet filtering and priority control work with Acila, and entries for them with Acila is more efficient than network based identifiers approach, with little overhead on performance.","PeriodicalId":294749,"journal":{"name":"Proceedings of the ACM SIGCOMM Workshop on Future of Internet Routing & Addressing","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133969873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
