Methods and apparatus for real-time traffic steering using real-time user monitoring data
Conventional internet routing is handled using routing protocols such as the Border Gateway Protocol (BGP). However, simple BGP does not account for latency, packet loss, or cost. To address this problem, smart routing systems that route traffic fast and in a cost-effective manner are implemented. In one approach, smart routing systems measure, compare, and analyze round-trip latencies and other metrics between a customer premises and one or more endpoints. Optimal inbound and outbound transit providers are selected for each endpoint based on these measurements. Other smart routing systems collect and analyze Real User Monitoring (RUM) data to predict latency performance of different content origins for serving data to a particular client based on the client's IP address and the content origins' IP addresses, which are ranked by performance. These rankings are used to steer traffic along lower latency paths by resolving Domain Name System (DNS) queries based on the performance associated with the IP addresses. |

Enhanced network stack
Some embodiments of the invention provide a new networking data path framework that employs one or more dedicated kernel threads to process network traffic on a host computer executing multiple machines (such as virtual machines or containers). This new framework is referred to as an Enhanced Networking Stack (ENS) in this document. In some embodiments, the dedicated kernel threads execute on dedicated CPU cores (e.g., one kernel thread per CPU core) to proactively poll physical NICs (PNICs) of the host computer and virtual NICs (VNICs) of the machines (e.g., VMs), and to perform packet processing operations on packets received by the host and packets transmitted by the machines. In some embodiments, each PNIC or VNIC is associated with one dedicated kernel thread, in order to avoid synchronization issues between the kernel threads. In the discussion below, these kernel threads are referred to as fast-path packet processing threads or as logical cores, or Lcores, and the physical and virtual NICs that are polled by the Lcores are referred to as polled network devices. In some embodiments, one Lcore can process multiple polled network devices. This is beneficial because in some embodiments one CPU core is dedicated to each Lcore (i.e., because one Lcore monopolizes the entire computing power of one CPU core), and it would be wasteful to dedicate one Lcore to just one polled network device, which might be underutilized. |
