摘要： An end host in a peer-to-peer system stores identifiers for both its peers and the neighbors of its peers. When the IP address of the end host and one of the peers changes, the end host's new IP address can be sent to each neighbor of the peer so that communication between the end host and the peer will not be lost. The order in which the neighbors of the peer are stored can be prioritized for faster delivery of the end host's changed IP address to the peer. The prioritizing can be by available bandwidth of the neighbors, proximity of the neighbors, trust between the peer and its neighbors, the probability that the IP address of the neighbors will change, etc. Proximity of the peers from each other and the end host can be a function of the identifier, which can be generated from a public key.

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.

摘要翻译： 假超时（STO）响应允许发送设备在检测到STO之后保守地调整拥塞状态参数并维护分组流。 由于STO的发生可能伴随着数据丢失，STO响应通过维持先前可用带宽的值并且增加发送主机可以基于返回的确认的模式发送的限制来耦合虚假超时和丢失事件。 特别地，每当从接收主机接收到指示数据分组的成功发送的确认时，发送主机可以发送的数据段的最大大小增加限制。 因此，可以保守地保持正数据流，同时避免进一步的分组丢失和可能已经被接收主机成功接收的数据分组的不必要的重新传输。

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.
