摘要： Wireless network interference is mitigated with client devices having wireless network interference mitigation logic and/or utilizing a usable bandwidth channel quality metric. In a described example implementation, a client device includes wireless network interference mitigation logic that monitors at least one channel condition of a wireless network and participates in a wireless network interference mitigation procedure based on the at least one channel condition. In another described example implementation, a usable bandwidth of a wireless channel is ascertained with respect to a native network, the usable bandwidth reflecting a difference between (i) a total channel capacity of the wireless channel and (ii) a portion of the total channel capacity that is consumed by wireless communications of one or more foreign networks. By way of example only, the at least one channel condition may be usable bandwidth. The wireless network interference mitigation logic may also be employed in non-client devices.

摘要： The present technique for automating service discovery and the set-up of a wireless network improves a user's experience when setting-up the wireless network and using one or more services. The technique includes automatic neighbor/service discovery using special beacons transmitted from wireless devices. Each special beacon identifies the wireless device (i.e., host) that transmitted the beacon along with the services provided by the device. For each special beacon that is received, a corresponding host name and the service provided by it are displayed in a graphical user interface. A user may select one or more of the host names and initiate a transmission of a network set-up and service request. The network set-up and service request identifies the selected host names and invites each selected host name to become a member of a wireless network. After the network has been set up, the service may be invoked automatically.

摘要： A spurious timeout (STO) response allows a sending device to conservatively adjust congestion state parameters and maintain the packet flow, after detection of the STO. Since occurrence of an STO may be accompanied by data loss, the STO response couples the spurious timeout and the loss event by maintaining a value of previously available bandwidth and increasing a limit that a sending host can send based on a pattern of returned acknowledgements. In particular, the limit is increased by the maximum size of a data segment that the sending host can send each time an acknowledgement is received from the receiving host indicating a successful transmission of a data packet. Thus, a positive data flow may be maintained conservatively while avoiding further packet losses and an unnecessary re-transmission of data packets that may have been successfully received by the receiving host.

摘要： A method for detecting a spurious timeout in a TCP network which can be used to avoid unnecessarily triggering the TCP rate adaptation is disclosed. Upon detection of a timeout on a given packet, a shortened packet version of the possibly lost packet is retransmitted. The retransmitted packet is at least one byte shorter than the original packet. The node receiving this retransmitted packet will acknowledge the receipt of the packet as specified in the TCP protocol. The acknowledgment will contain the sequence number of the lowest byte the receiving node has not yet received. Because the retransmitted packet is shorter than the original packet, the sequence number of this as yet not received byte will be less than or equal to the last byte of the original packet if the original packet was not received indicating a valid timeout. If the sequence number in the acknowledgment is greater than the last byte of the original packet than the original packet was received correctly and the timeout was caused by a lost acknowledgment and is considered a spurious timeout. In the case of a spurious timeout the congestion control mechanisms in the TCP protocol need not be used.

摘要翻译： 公开了一种用于检测可以用于避免不必要地触发TCP速率适配的TCP网络中的虚假超时的方法。 在检测到给定分组上的超时时，重传可能丢失的分组的缩短的分组版本。 重传的分组比原始分组短至少一个字节。 接收该重发分组的节点将确认在TCP协议中指定的分组的接收。 确认将包含接收节点尚未接收的最低字节的序列号。 由于重传的分组比原始分组短，因此未接收到的字节的序列号将小于或等于原始分组的最后一个字节，如果未收到指示有效超时的原始分组。 如果确认中的序列号大于原始数据包的最后一个字节，而不是原始数据包被正确接收，并且超时是由丢失的确认引起的，并且被认为是虚假超时。 在虚假超时的情况下，不需要使用TCP协议中的拥塞控制机制。

摘要： Systems and methods for Compound TCP are described. In one aspect, a single TCP connection is opened for communication of data over a compound stream between first and second computing devices. The compound stream includes two or more logical data streams to emulate congestion control behavior of multiple separate network (TCP) connections. Data flow over the compound stream is managed with multiple different congestion control schemes.
