Onload® — 应用加速软件
Onload® 可显著加速和扩展内存数据库、软件负载均衡器和 Web 服务器等网络密集型应用。使用 Onload，数据中心不仅可在其云网络上支持 400% 以上的用户，同时还可实现更高的可靠性、更高的服务质量 (QoS) 以及更高的投资回报，无需对现有应用进行修改。
Onload 允许数据中心实现：
- 更高的弹性和效率，从而降低总体拥有成本 (TCO)
- 更高的峰值事务处理速率，消除服务限制
- 更快的响应时间，带来更低的网络抖动，从而可带来优异的服务质量
特性:
- 增加 400% 以上的用户
- 将消息发送速率提高 100%
- 将服务器占用最小化 25%
- 将时延锐减 50%
- 体验近零抖动
- 最大化资本支出和运营成本
- 提升服务质量
扩大数据中心投资
Onload 允许数据中心为其它任务重新部署 25% 以上的负载平衡服务器，从而可实现资本支出投资的回报。或者，数据中心可通过减少整个服务器占用空间来减少运营开销。
您的应用运行速度有多快？
Onload 几乎可加速所有基于 TCP 的网络密集型应用。采用 Onload 时，典型的性能改进包括：
| 使用案例 | 应用 | 性能提升 | 基准测试文档 |
|---|---|---|---|
| 内存数据库 | Couchbase、Memcached、Redis | 100% | |
| 软件负载平衡器 | NGINX +、HAProxy | 400% | |
| Web 服务器／应用 | NGINX +、Netty.io | 50% |
Xilinx 已编制了一系列使用手册 (cookbook)，其中列出了我们使用过的服务器、完成的配置以及具体完成的测试。这些使用手册旨在帮助客户复制已获得的成果，因为有时这些成果可显现出色的功能性。

Telemetry is the Art Behind Capturing Network Packet Data
In this context telemetry is remotely collecting data on a given network packet. That data can be where a given packet was at a specific point in time along with the abstracted metadata that represents the network flow the data belongs to. Knowing everything about your network data can enable you to tune application performance while also securing your network. Xilinx provides several different methods for capturing network packet telemetry directly from the card itself or through a performance SolarCapture Pro driver.
XtremePacket Engine
Rules based action on incoming and outgoing packets can be time stamped, counted, cloned, dropped, filtered and translated
L2 Switch
Incoming and outgoing packets can switched and Intelligently steered to a collection of cores on the host
SolarCapture Pro Libpcap Driver
Xilinx’s SolarCapture Pro (SCP) is a kernel bypass performance tuned replacement for Libpcap. It is designed to provide a high rate of packet capture to memory, in the 10s of millions of packets per second. SCP supports three operating modes: sniff, steal or both. In sniff mode packets are delivered normally to applications or the network, but a clone of each packet, both transmitted and received packets, is sent to SCP for processing. In steal mode SCP receives all the packets coming into an interface. Finally, both modes can be engaged so that two parallel applications can analyze the same packet streams. To facilitate this SCP has a feature called clustering, which enables the creation of clusters of cores that can then be attached to capture instances for processing. SCP supports Berkley Packet Filter (BPF) which can be applied to capture so that SCP only receives the packets requested while all others follow their normal path.
