Existing interval-reset-based sketch and hash table approaches are incapable of delivering consistent and high accuracy when operating in heterogeneous scenarios where various applications with different purposes require the flows to be tracked at different time scales, not to mention their dependence on the control plane for data structure management. We propose HashAge and SkAge, novel in-network time-decaying algorithms for hash table- and sketch-based HH detection. We show that our proposed algorithms offer consistent and higher detection accuracy while operating in heterogeneous demands whilst not requiring any data structure management from the control plane at all.","PeriodicalId":396272,"journal":{"name":"Proceedings of the SIGCOMM '20 Poster and Demo Sessions","volume":"328 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114656296","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}

They combine advanced approaches from predecessors such as TCP (e.g., congestion and flow control, reliability) and HTTP/2 (H2) (e.g., stream multiplexing, prioritization), with cutting-edge features (e.g., 0-RTT data, connection migration). As QUIC runs on top of UDP, these intricate systems have to be re-implemented from scratch, often in userspace, which has turned out to be error-prone. QUIC also fully integrates TLS 1.3 and is end-to-end encrypted at the transport layer. This means that, unlike with TCP, elements like packet and acknowledgement numbers are indiscernible to passive observers in encrypted packet traces (e.g., .pcap files analyzed with tools like Wireshark). As such, QUIC requires (ephemeral) TLS keys for even high-level analysis, leading to scalability, privacy and security issues. It is clear that QUIC+H3's overall complexity and heavy security focus make them difficult to implement, debug, observe, analyse, use and teach in practice.","PeriodicalId":396272,"journal":{"name":"Proceedings of the SIGCOMM '20 Poster and Demo Sessions","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134512645","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}

To manage the communication among services, as an emerging microservice deployment paradigm, service mesh goes further.

Data traffic follows the inverse direction of BGP route propagation. For the outbound traffic, an AS can make its own selection in the range of the routes received from its peering neighbor ASes, and change the traffic outbound paths for better performance or bypassing failures. It is more difficult for ASes to control inbound traffic paths because it cannot determine the selection for remote ASes. An AS only has to manipulate BGP path attributes of the advertised prefixes it owns to trigger the potential path change from other ASes to itself.","PeriodicalId":396272,"journal":{"name":"Proceedings of the SIGCOMM '20 Poster and Demo Sessions","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129211278","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}

Existing malfunction detection (MD) approaches are often unable to achieve both simultaneously for large scale networks.

Considering many networks are designed to be symmetric and malfunctions are usually only a small portion, this paper propose A4 - an automatic MD system which combines node embedding based on structural similarity in graphs (Graph-Wave which scales linearly) with density-based spatial clustering (DBSCAN) to distinguish malfunctions as the noises efficiently for original symmetric networks.","PeriodicalId":396272,"journal":{"name":"Proceedings of the SIGCOMM '20 Poster and Demo Sessions","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116265783","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}
