On the boundary of data center, the gateway needs to execute a series of network functions for each incoming packet. The Network Function Virtualization (NFV) technology leverages commodity servers to flexibly implement network functions. This solution provides satisfying processing and storage capability. However, state-of-the-art NFV platforms can merely process network functions at the line rate of 10~40Gbps. Supporting throughput of terabits per second requires dozens or even hundreds of servers operating exclusively for network functions, which is not only expensive but also difficult to maintain. On the other hand, programmable packet processing hardwares proposed in recent years offer a new platform for implementing network functions. They can execute user-defined packet processing logics at ultra-high line rate while containing limited processing and storage resources. The software network function platform and programmable packet processing hardware own complementary features, which inspire us to combine them together to propose the heterogeneous gateway platform called FlexGate. Based on the observations of traffic pattern and function features, we propose an efficient way to deploy network functions and matching rules in hardware/software to give full play to their respective advantages. In programmable hardware, to further optimize resource utilization, a new load balance scheme is proposed to spread load. Experiments show that FlexGate can execute realistic workload at the rate of at least 1.5Tbps, and the average latency is 1.28μs.","PeriodicalId":107260,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Workshop on Networking","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125641550","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}

Beginning with Receive Side Scaling (RSS), various schedulers have been proposed to steer packets to cores while preserving locality. However, these techniques are either too inflexible (randomly steering traffic at the NIC) or slow (bottlenecked by a central CPU-based scheduler). In this paper, we present Elastic RSS (eRSS), a system that extends traditional RSS by scheduling packets and cores using emerging programmable NICs with new abstractions (e.g., map-reduce). Operating at the NIC with minimal intervention from the host CPU, eRSS responds to load shifts at line rate and on a per-packet basis. eRSS also supports distributed packet stealing and fast preemption per-core to improve tail latency under heavy-tailed service time distributions. Our preliminary evaluation shows that eRSS increases CPU efficiency while responding to rapid load changes and meeting real-world tail latency constraints of 100 μs.","PeriodicalId":107260,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Workshop on Networking","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125834165","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}

Network operators must also ensure high utilization of network capacity to reduce cost. Existing approaches that statically partition network capacity, in either time or space, provide good isolation but suffer from under-utilization. Existing schemes that dynamically allocate capacity to tenants incur either decreased fairness or high tail flow completion times. To overcome these limitations, we propose Ether. Ether is able to overcome these limitations because it can prioritize bursty flows during short congestion episodes while still ensuring fairness at long timescales. In this paper, we present a preliminary design of Ether and discuss its feasibility in today's programmable switches. Our evaluations show that, at high loads, Ether achieves 23% improvement in tail flow completion times (FCT) when compared with idealized fair queueing (FQ) while still providing similar fairness as FQ. In contrast, pFabric, which optimizes FCT, worsens fairness by a factor of 1.8 when compared with Ether.","PeriodicalId":107260,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Workshop on Networking","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130728901","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}

In multi-tenant environment, however, the newly introduced ECN-enabled TCP greatly impairs the performance of applications with out-dated and miscon figured TCP stacks. The reason is that the ECN-enabled datacenter switch fails to treat the mixed TCP traffic fairly, causing the distinguished performance gap between the ECN-enabled and ECN-disabled TCPs. This paper proposes DDT (Dual Dynamic Thresholds), an active queue management algorithm (AQM) that aims to achieve the flow-level fairness when the heterogeneous TCP traffic coexists. DDT monitors the switch queue in real time, and dynamically tunes the distance between ECN-marking and packet-dropping thresholds to mitigate the competitiveness difference between the ECN-enabled and ECN-disabled TCP. Our preliminary real implementations and testing results show that DDT elegantly fills the competitiveness gap of heterogeneous TCP traffic without disturbing their own control loops, while only introducing acceptable deployment overhead at the switch.","PeriodicalId":107260,"journal":{"name":"Proceedings of the 3rd Asia-Pacific Workshop on Networking","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129613181","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}
