Checkpoint-based fault-tolerant methods have been widely used to enhance the reliability of stream processing systems. To ensure exact data recoveries upon failures, full-backup mechanisms are used to store a complete copy of data, which introduces substantial runtime overhead and increases output latency. In the meantime, a wide range of online processing applications prefer quick-and-dirty results with a slight degradation inaccuracy to delayed exact results. This paper introduces a novel approximate fault-tolerant problem (OAFP) with the objective of reducing the failure-free fault-tolerant overhead and ensuring user-defiled output accuracy requirement upon failure at the same time. We present an approximate fault-tolerant scheme based on sampling backup mechanism and study the trade-off between fault-tolerant overhead and output accuracy in stream processing systems. We proposed two algorithms to compute backup plans for both single-node failure and correlated failure scenarios. Extensive experiments with different types of stream topologies are conducted on our simulator to verify the correctness and effectiveness of our approach. We prove our solution guarantees the output accuracy requirement with minimum FT latency for directed acyclic graph (DAG) stream topologies with single-node failures.","PeriodicalId":137835,"journal":{"name":"2020 29th International Conference on Computer Communications and Networks (ICCCN)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130236011","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}

These models are usually resource-consuming due to the large number of processors required and long execution time. Although the performance and scalability of individual physical system model have been improved over the past years, coupled climate systems still suffer from low efficiency when sharing resource across models. This paper focuses on the process scheduling strategy of Coupled Earth System Model (CESM), a widely applied coupled system model. Instead of pursuing best speedup efficiency for individual component, the proposed resource allocation strategy allows components to execute on compromised sub-optimal setup and still maintains relatively high parallel speedup. With this flexible resource allocation strategy, we further propose a Coordinated Process Scheduling Algorithm (CPSA) to make efficient resource sharing configurations, including resource allocation and process layout of components. We integrate CPSA as a tool into CESM program, and deploy it on Huawei Kunpeng Platform. Speedup curves of CESM components are prepared in advance based on sampling tests. Experimental data show that our algorithm reduces up to 52.6% of execution time compared with CESM default strategy. We also present simulation data to show that our algorithm is efficient for the platforms with up to a million cores.","PeriodicalId":137835,"journal":{"name":"2020 29th International Conference on Computer Communications and Networks (ICCCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130288589","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}

Leader-followers formation is a widely used swarm management scenario where a leader drone frequently broadcasts controlling messages to all follower drones to achieve collaboratively a common mission. However, managing such a UAV swarm, especially when the member drones dynamically join and leave the swarm, introduces significant security challenges and performance overhead.In this work, we propose a Swarm Broadcast Protocol (SBP) to facilitate the security protection of leader-followers formation based UAV swarms. SBP contains a security key management scheme that manages a broadcast key among the swarm for leader to broadcast encrypted messages to followers. When swarm membership changes, the broadcast key will be updated and synchronized among the swarm to maintain both backward and forward secrecy. The overhead of SBP is small that only constant computational overhead is needed for both swarm leader and followers to achieve key synchronization when a new drone joins regardless of the current swarm size. This feature would highly reduce the overhead when there are many individual drone joining events. Through experiments on network emulator, we show that SBP achieves lowest bandwidth overhead and CPU utilization to handle multiple swarm membership changing events, comparing with two public-key-based swarm management protocol baselines.","PeriodicalId":137835,"journal":{"name":"2020 29th International Conference on Computer Communications and Networks (ICCCN)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131553194","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}

The middleboxes offer proprietary solutions and encrypted traffic poses a challenge when middleboxes employ packet payload inspection techniques for connection establishment. Session key sharing and decryption followed by re-encryption of the traffic, for correctly routing to the private host, increases the connection latency and also poses a higher threat in case of traffic interception by a malicious third-party.In this paper, we present a novel open-source ALG, called Sec-ALG, for providing secure end-to-end communication to the web servers situated in the private address space. Sec-ALG relies on the technique of light Deep Packet Inspection (DPI) for protocol detection and session establishment using a novel parser-lexer generator called YaLe. The proposed approach offers increased security by maintaining end-to-end encryption for an HTTPS connection. Our experimental analysis demonstrates that Sec-ALG reduces the HTTPS connection latency in comparison to the NGINX reverse proxy using a 24-core host machine. Moreover, Sec-ALG handles requests at a three-fold increased rate than NGINX proxy when tested with 100 concurrent connections. The ALG can be used either as a standalone solution or a component of the Realm Gateway, that is a generic interworking solution between public and private networks. The presented work is part of an extensive ongoing research at Aalto University focusing on embedding policy based trust into the network.","PeriodicalId":137835,"journal":{"name":"2020 29th International Conference on Computer Communications and Networks (ICCCN)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131925951","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}
