To achieve an efficient global delivery of content, today content providers usually employ content delivery networks (CDNs) located at the edge of ISP networks from where content is delivered to end users via IP unicast. Many OTT services could benefit from a better support within the ISP's network, e.g. by packet duplication to deliver OTT video streams. While traditional solutions like IP multicast did not prevail, SDN-based alternatives have started to gain attention recently. In contrast to traditional approaches, SDN enables ISPs to support network services in a more manageable and flexible manner. However, the approaches proposed so far are quite rigid and keep state at every network device, independent of the multicast group size. To alleviate this problem, this paper proposes a new approach termed ASDM enabling ISPs to dynamically adjust the tradeoff between bandwidth and state for any multicast service. It is shown that, given ISP-defined bandwidth and state cost functions, the optimal parameter for ASDM can be derived and applied for a transparent multicast-to-unicast conversion achieving the desired characteristics. The proposed approach results in up to 30% bandwidth reduction compared to unicast while using only a seventh of the network state compared to traditional multicast.","PeriodicalId":426452,"journal":{"name":"Proceedings of the 2015 1st IEEE Conference on Network Softwarization (NetSoft)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114702079","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}

Due to a lack of analytical tools, one cannot simply justify the worthiness of outsourcing network functions. This paper proposes a decision support framework for network function outsourcing, called Location-aware Network Function Outsourcing (LawNFO), aiming to identify which network function is worth to be outsourced to the cloud. LawNFO constructs a network-function graph and maps the cost of network function processing units and the data transmission between any network-function pairs onto the graph. The network function outsourcing problem is formulated as an optimization problem targeting on the minimum network cost. To solve the optimization problem based on the graph input, we develop an efficient and fast heuristic algorithm, called Node-weighted Contraction (NowCont), that encompasses the graph partitioning and graph augmentation techniques. This paper performs simulation to evaluate the performance of LawNFO with NowCont algorithm in two aspects: 1) the closeness ratio to the optimal solutions and 2) the network cost comparing to that of all-in-house and most-in-cloud network function placement models. The simulation results illustrate that the NowCont algorithm yields the solution closest to the optimal solution. The evaluation through two use cases show that LawNFO is of benefit to the enterprises for the decision of network function outsourcing.","PeriodicalId":426452,"journal":{"name":"Proceedings of the 2015 1st IEEE Conference on Network Softwarization (NetSoft)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931844","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}
