| 发明名称 | Techniques for protecting against denial of service attacks | ||
| 摘要 | Techniques for protecting against denial of service attacks are provided. In one embodiment, a network device can extract one or more values from a Transmission Control Protocol (TCP) ACK packet sent by a client device, where the one or more values encode TCP option information. The network device can further decode the one or more values to determine the TCP option information and embed the TCP option information into the TCP ACK packet. The network device can then forward the TCP ACK packet with the embedded TCP option information to a server. | ||
