Multicast, as a transmission strategy with high spectral efficiency, has not been widely studied in heterogeneous cellular network (HetNet). Meanwhile, in order to overcome the shortcoming of conventional multicast scheme (CMS) that the throughput of multicast group is constrained by the user with lowest data rate, we propose a multicast scheme with subgroups over HetNet to effectively improve the system throughput. We formulate an expression of system throughput of the proposed multicast scheme with subcarrier and power constraints and maximize it by optimizing subgroups configuration. It can be proved to be a NP-hard combinatorial problem, then we decouple it into three subproblems, namely, user association (UA), subgroup formation (SF) and resource allocation (RA). In UA, we present a traffic-oriented access method based on reference signal receiving power (RSRP). In SF, the associated users are divided into several subgroups according to their channel state information (CSI) and the users in one subgroup are served with appropriate rate determinated by the CSI level of the subgroup. In RA, Round-Robin schedule and Equal Power schedule are adopted for subcarrier allocation and power allocation respectively. Simulation results show that the system throughput is significantly improved by using our scheme.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128492285","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}

However, we notice that the shortcoming in networking of this technology, such as complexity in communication between containers in different hosts and the waste of network addresses when directly allocating public IP addresses to containers, limits its availability on complicated scenarios. In order to solve these problems, we propose a solution named SDN-based NGroups Management Scheme (SNMS). In our solution, containers are organized into different NGroups, and public network addresses are allocated to NGroups too. Containers in the same NGroup can communicate with each other using “localhost” as target, and clients outside of an NGroup can fetch services using this NGroup's address. We adopt SDN technology to route traffic in order to accomplish these objectives. In this paper, we present detailed design for the solution and build a prototype based on our design. By using our prototype, container's position has nothing to do with service providing, and public network addresses are greatly saved because containers inside an NGroup share the same network configuration to the outside world. In the meantime, the performance of creating containers and HTTP downloading in our prototype is not bad than, in some case even better than, those in existing solutions nowadays.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124368031","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}

Despite the importance of metadata in the file system, the overhead of maintaining the metadata cannot be taken lightly. It is because the metadata also have to be persisted on the storage device and it consumes IO bandwidth as well as creates journaling overhead. In this paper, we find that the random write with synchronous performance of a storage is significantly affected by not only the hardware performance but also timer interrupt interval of the kernel. Extending the timer interrupt interval allows reducing the write volume and increasing the random write followed by fsync() performance of EXT4 file system. We propose intermittent mtime timestamp update on Coarse grain mtime interval instead of Fine grain mtime interval. The experiment results with mtime update interval of 1 second show that the total write volume is decreased by 75% and 28%, respectively compared to total write volume of 1 ms and 10 ms mtime interval, and the throughput increased 3.1× and 1.2× compared to 1 ms and 10 ms mtime interval. Coarse grain mtime update is resolve to the journaling overhead issues while still logging mtime timestamp.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116577705","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}
