云网关是云平台的基本组件，其中各种网络功能（例如，L4/L7负载平衡、网络地址转换、状态防火墙和SYN代理）被部署来处理数百万个连接和数十亿个数据包。通过<italic>可扩展的流量管理</italic>机制提供<italic>高性能</italic>和<italic>故障弹性的</italic>数据包处理对于确保云提供商的服务质量至关重要，因此非常重要。为了低成本和高灵活性，现在许多网络功能都是用商用服务器在软件中实现的。然而，现有的基于软件的网络功能框架往往提供了这些功能的一部分，而不能同时满足上述三个需求。为了解决这些问题，在本文中，我们介绍TRIPOD，一个新的网络功能框架，专门为云网关。TRIPOD识别了松散耦合<italic>的流量</italic>、<italic>处理逻辑</italic>和<italic>状态</italic>的基本局限性，通过<italic>简单、高效的流量处理机制</italic>和<italic>高性能的状态管理服务，</italic>将这三个元素与云网关的独特特性结合起来进行管理。TRIPOD采用了多种有效的技术和优化，能够实现<italic>可扩展的流量管理</italic>（即使是~Tbps的流量，流量规则也小于100条）、<italic>高性能</italic>（与现有技术相比，延迟减少了40%）和<italic>故障恢复能力</italic>（与现有技术相比，数据包/连接丢失率相似），即使在非常繁忙的流量下，也具有合理的开销（小于工作负载流量的10%），非常适合用于云网关。
Cloud gateways are fundamental components of a cloud platform, where various network functions (e.g., L4/L7 load balancing, network address translation, stateful firewall, and SYN proxy) are deployed to process millions of connections and billions of packets. Providing <italic>high-performance</italic> and <italic>failure-resilient</italic> packet processing with a <italic>scalable traffic management</italic> mechanism is crucial to ensuring the quality of service of a cloud provider, and hence is of great importance. Many network functions nowadays are implemented in software with commodity servers for low cost and high flexibility. However, existing software-based network function frameworks oftentimes provide part of these features, while cannot satisfy all three requirements above simultaneously. To address these issues, in this paper, we introduce TRIPOD, a novel network function framework specialized for cloud gateways. Having identified the fundamental limitations of loosely coupling <italic>traffic</italic>, <italic>processing logic</italic> and <italic>state</italic>, TRIPOD jointly manages these three elements with the unique characteristics of cloud gateways, which is enabled by a <italic>simple, efficient traffic processing mechanism</italic>, and a <italic>high performance state management service</italic>. Adopting several effective techniques and optimizations, TRIPOD is able to achieve <italic>scalable traffic management</italic> (<100 flow rules for even ~Tbps traffic), <italic>high performance</italic> (reducing 40% of latency compared with state of the art) and <italic>failure resilience</italic> (similar packet/connection loss rate compared to state of the art), with reasonable overheads (less than 10% of the workload traffic) even under an extremely heavy traffic, making it a good fit for cloud gateways.
