摘要： Methods and systems are provided for improving a firewall implemented at a WLAN infrastructure device (WID). The WID includes a stateful firewall that implements firewall rules based on an ESSID of the WID to specify whether traffic is allowed to or from the ESSID. For example, in one implementation of such a firewall rule, packets that are required to be sent out on all wired ports can be blocked from being flooded out on WLANs (e.g., the packet is allowed to pass only to the wired ports). A method and system are provided for preventing a malicious wireless client device (WCD) that is transmitting undesirable traffic from using RF resources by deauthenticating the malicious WCD to remove it from the WLAN and blacklisting it to prevent it from rejoining the WLAN for a time period. Method and systems are also provided for either “on-demand” and/or predicatively communicating state information regarding an existing firewall session.
摘要翻译：提供了用于改进在WLAN基础设施设备（WID）实现的防火墙的方法和系统。 WID包括一个状态防火墙，其实现基于WID的ESSID的防火墙规则，以指定流量是否允许来自或来自ESSID。例如，在这种防火墙规则的一个实现中，可以阻止在所有有线端口上发出的分组在WLAN上被洪泛（例如，该分组被允许仅通过有线端口）。提供了一种方法和系统，用于防止恶意无线客户端设备（WCD）通过解密恶意WCD将其从WLAN中移除并将其黑名单以防止其在一段时间内重新连接WLAN，从而使用RF资源发送不期望的流量。还提供方法和系统用于关于现有防火墙会话的“按需”和/或预先传达状态信息。

摘要： A method and apparatus of establishing a connection between a wireless device and a second device includes maintaining a state of the connection between the wireless device and the second device, and receiving an indication that a wireless link to the wireless device has been lost or may be lost. In response to the receiving the indication that the wireless link to the wireless device has been lost or may be lost, the state of the connection is transitioned from a first state to a second state.

摘要： The present disclosure provides systems and methods improving Transmission Control Protocol (TCP) network congestion avoidance in wireless networks. Specifically, the present disclosure decouples wired and wireless TCP connections at a wireless access point, thin access point, wireless switch, etc. The wired TCP session is terminated on the wireless access device and a wireless TCP session is automatically started for the last hop to a mobile unit. Advantageously, the wireless TCP session may utilize a congestion avoidance algorithm optimized for wireless network. Furthermore, wireless local area network (WLAN) information may be tied to the TCP stack for improved performed, e.g. an IEEE 802.11 Acknowledgement (ACK) may be considered as equivalent to a TCP ACK from the mobile unit. By splitting a TCP downstream connection into two—wireless and wired, high-jitter, high-loss wireless hops may be hidden from the remote host's TCP socket.
摘要翻译：本公开提供了改进无线网络中的传输控制协议（TCP）网络拥塞避免的系统和方法。具体地，本公开在无线接入点，小接入点，无线交换机等上去耦合有线和无线TCP连接。有线TCP会话在无线接入设备上终止，并且无线TCP会话被自动启动用于最后一跳一个移动单元。有利地，无线TCP会话可以利用针对无线网络优化的拥塞避免算法。此外，无线局域网（WLAN）信息可以被绑定到TCP堆栈以用于改进的执行，例如。可以将IEEE 802.11确认（ACK）视为等同于来自移动单元的TCP ACK。通过将TCP下游连接拆分为双无线和有线，高抖动，高损耗无线跳数可能会从远程主机的TCP套接字中隐藏。
