摘要： A resolver queries a DNS server for any network addresses associated with the particular domain name. If the resolver detects a response for the DNS server with multiple network addresses for a particular domain name, then the resolver creates and sends a shortest path query to at least one router enabled to receive and respond to shortest path queries. The shortest path query indicates at least one source address and the multiple destination addresses returned by the DNS server for the particular domain name. The router detects a separate length for each path accessible between each source address and each of the multiple destination addresses. The router then orders the destination addresses from shortest path to longest path and returns the ordered destination addresses to the requesting resolver. The resolver caches the ordered network addresses in the local cache in association with the particular domain name, such that for future requests for the particular domain name, the resolver retrieves from local cache the shortest path network address as ordered by the router. In addition, the resolver, responsive to receiving the ordered destination addresses, selects the shortest path network address for a response to an application requesting the resolution of the particular domain name.

摘要： DHCP lease negotiation is performed in advance of a specified time when the IP address is needed. The client sends a DHCP discover message with an advance lease option indicating a future time when an IP address is needed. The DHCP server reserves an IP address available at the requested time for the requesting client and sends a DHCP acknowledgment of the reservation. Thereafter, the client sends a DHCP discover message requesting the reserved IP address, and the DHCP server assigns it to the client at the scheduled time.

摘要： A method and system for self-healing of routers within a distributed computer network. In response to a detected communication error at a local router over a primary communication path to a distant router, an alternate path is established. Thereafter, a diagnostic process is initiated in the distant router via the alternate path. Communication settings are then reconfigured in the distant router and communication via the primary communication path is tested. If communication is restored, the new communication settings are made permanent. If communications via the primary path are not restored, alternate communication settings are attempted in the local router and communication is tested again. If communication is re-established via the primary path, the new communication settings are made permanent.

摘要： A method, system, and program for accessing data processing systems behind a NAT enabled network are provided. According to one aspect of the present invention, a NAT data processing system is located behind a NAT enabled network with a NAT device as a gateway to the NAT enabled network. A client system located outside the NAT enabled network queries the NAT device for the address of the NAT data processing system located behind the NAT enabled network. The query is automatically routed through the NAT device to a DNS server. The DNS server then returns an address for the NAT data processing system and source routing for the NAT device. The NAT device forwards the address and source routing to the client system. Then, the client system sends packets to the NAT data processing system at the address with source routing through the NAT device, such that the NAT data processing system behind the NAT enabled network is directly accessed by the client system from outside the NAT enabled network.

摘要： A receiving host in a TCP/IP network sends an acknowledgment indicating a received data packet is corrupt. The sending host will begin transmitting with a new field set in the IP header called a check-TCP-checksum bit, thereby requesting that all routers in the TCP/IP network perform a checksum on the entire received packet. Routers in the TCP/IP network will perform a complete checksum on an entire packet with the check-TCP-checksum bit set, and not just on the IP header. The routers continuously monitor the ratio of corrupt packets received on a particular port that fail the entire packet checksum to the total number of packets received on that port. If the ratio of corrupt-to-received packets exceeds a corruption threshold, the router assumes that the associated link is causing data corruption and issues a routing update indicating that the link is bad and should be avoided. Once the retransmission rate between the sender and receiver drops below a threshold level, the bad link has been detected and avoided within the TCP/IP network and the check-TCP-checksum option in the IP header is no longer set in data packets transmitted to the receiver host.
摘要翻译： TCP / IP网络中的接收主机发送指示接收到的数据包已损坏的确认。发送主机将开始使用称为检查TCP校验和位的IP报头中设置的新字段进行发送，从而请求TCP / IP网络中的所有路由器对整个接收到的数据包执行校验和。 TCP / IP网络中的路由器将对整个数据包执行完整的校验和，同时检查TCP-checksum位，而不仅仅是在IP报头上。路由器连续监视在特定端口上接收的损坏数据包的总数与在该端口上接收的数据包的总数之间的比例。如果损坏的数据包的比例超过了破坏阈值，则路由器假设相关联的链路导致数据损坏，并发出路由更新，指示链路不良，应该避免。一旦发送方和接收方之间的重传速率下降到阈值以下，就会在TCP / IP网络内检测并避免不良链路，并且IP报头中的check-TCP-checksum选项不再被设置在发送到接收主机。
