摘要： A method includes receiving a command to migrate a workload partition from a source machine to a target machine. The source machine and the target machine are communicatively coupled to a first subnetwork and a second subnetwork, respectively. The workload partition has a source network address defined by network addressing of the first subnetwork. The method also includes determining a socket connection providing network communication between the workload partition and a host. The method includes notifying the host that the workload partition is migrating from the source machine to the target machine, wherein in response to the notifying the host is on alert to receive, through a network tunnel communication, an identification of a target network address that is assigned to the workload partition after the workload partition is migrated to the target machine. The workload partition is migrated from the source machine to the target machine.

摘要： A method identifies a network socket on a machine by assigning a non-IP address socket anchor and a port number to the network socket. A socket anchor may comprise a globally unique number. In some embodiments, a socket anchor comprises a number having a preselected number of bits. The number having the preselected number of bits may comprise a selected number associated with the machine concatenated with a number of randomly generated bits. The number of bits of the selected number plus the number of randomly generated bits is equal to the preselected number of bits. In some embodiments, the selected number associated with the machine is a Media Access Control (MAC) address of a network interface associated with the machine.

摘要： Mechanisms are provided for assigning addresses for use in communications between computing devices. With these mechanisms, a centralized domain name registrar server assigns a unique global identifier to a domain of a site such that the unique global identifier uniquely identifies the domain. The unique global identifier is received in a data processing system from the centralized domain name registrar server. The site is divided into a plurality of sub-domains and a unique sub-domain identifier is assigned to each sub-domain in the site such that the unique sub-domain identifier uniquely identifies a corresponding sub-domain in the site. The global identifier for the domain of the site and the sub-domain identifiers of the sub-domains in the plurality of sub-domains are provided by the data processing system to routers of the site for use in associating addresses with devices of the site.

摘要： A new instance of a connection that is in the wait state can be established while mitigating connection identifier collisions. Based on a connection identifier in a connection request received at a server from a client, it is determined that a previous instance of a connection represented by the connection identifier is in a wait state. An acknowledgement message comprising wait state parameters associated with the connection identifier and original connection parameters associated with the previous instance of the connection in the wait state is provided from the server to the client. In response, the server receives a compliance message comprising updated wait state parameters and updated connection parameters from the client. The new instance of the connection represented by the connection identifier that previously represented the previous instance of the connection is established based, at least in part, on the updated wait state parameters and the updated connection parameters.

摘要： Mechanisms are provided for resolving a domain name. The mechanisms send a request, from a resolver executing on the data processing system, to a name server requesting a resolution of a domain name into an address. A response to the request is received that includes a local address. The local address has a scope that is local to a site and is not global in scope. A determination is made as to whether the local address corresponds to a domain associated with the resolver. Communications are then performed with a device corresponding to the domain name using the local address in response to a determination that the local address corresponds to a domain associated with the resolver.

摘要： A method, computer program product, and apparatus for transmitting a message over a network are presented. A processor unit receives the message for transmission over the network and a portion of an address for a source from which the message is to be transmitted. The processor unit identifies an interface configured to transmit messages from the source onto the network using the portion of the address. The processor unit then transmits the message from the source onto the network using the interface.

摘要： Mechanisms are provided for determining a path maximum transmission unit of a path between a source node and a destination node of the path. These mechanisms transmit an echo request packet from the source node to the destination node along the path. The mechanisms further determine, by at least one intermediate node along the path, whether a size of the echo request packet is greater than a maximum transmission unit (MTU) of a next link of the path from the intermediate node to a next node along the path. Moreover, the mechanisms record, by the at least one intermediate node, the MTU of the next link in the echo request packet in response to the determination that the size of the echo request packet is greater than the MTU of the next link.

摘要： Blind attacks on a protocol connection, such as a TCP connection, are prevented by inserting checksums computed during protocol connection establishment handshake into data sent through the connection and invalidating data sent through the connection that lacks the protocol setup information checksums. Reset attacks are prevented by invalidating reset requests unless a master checksum computed from the protocol setup information checksums is included with the reset request. Checksums computed from protocol setup information have improved robustness by including a random number with the protocol setup information.
摘要翻译： 通过将在协议连接建立握手期间计算出的校验和插入通过连接发送的数据，并使通过缺少协议设置信息校验和的连接发送的数据无效，可以防止对协议连接（例如TCP连接）的盲目攻击。 除非重置请求中包含从协议设置信息校验和计算的主校验和，否则无效复位请求可以防止复位攻击。 从协议设置信息计算的校验和通过将协议设置信息包括随机数来改善鲁棒性。
