摘要： A method in a node for managing authorized attempts to access the node. A packet is received from a source, wherein the packet includes a first key. A determination is made as to whether the first key matches a second key for the node. The packet is dropped without a response to the source if the first key does not match the second key. Information from the packet is stored in response to this absence of a match. The information is sent to a selected recipient in response to a selected event, which may be, for example, either immediately or in response to polling to see if the information is present.

摘要： A method for enabling a Q_key that is tamper proof from applications on a distributed computer system to protect selected network operations is provided. Applications and an operating system (OS) execute on the end nodes and each may access various network resources. In the invention, the network resources are configured for selective access by particular applications or OS.In a preferred embodiment, a control bit of a Q_key, which allows applications to authenticate their use of particular communication resources, i.e., the send and receive queues, is reserved and utilized to signal whether a particular application is allowed access to the resources. Setting the control bit to 0 allows the Q_key to be set by an application directly. When the control bit is set to 1, the Q_key cannot be set by an application and can only be set using a privileged operation performed only by the OS.

摘要： A method for associating reliable datagram queue pairs with an underlying end-to-end context of a channel adapter is provided. The method comprises storing a reliable datagram domain (RDD) within the context of a reliable datagram queue pair (RD QP). The same RDD is stored within an end-to-end context (EEC). A partitioning key (P—key) is also stored within the EEC. The RDD cannot be accessed by consumer processes. In the case of incoming messages, the P—keys of the incoming data packet and EEC are compared. If P—keys match, then the RDD's of the RD QP and EEC are compared. If the RDD's match, the packet is processed normally. In the case of outgoing messages, the RDD's of the RD QP and EEC are first compared, and if they match, the P—Key of the EEC is inserted into the transport header of the data packet.

摘要： An apparatus and method for implementing multicast in system area network channel adapters are provided. With the apparatus and method, a multicast packet is received in a channel adapter of an end node. The channel adapter determines which local queue pairs are party of the multicast group identified by a destination local identifier in the multicast data packet. Based on this determination, the channel adapter replicates the data packet and delivers a copy of the data packet to each local queue pair that is part of the multicast group.

摘要： A method and system are provided for dynamically informing an operating system (OS) of a distributed computer system, when a (new) device is added on the network. An OS registers with the subnet administrator (SA) to be notified when a new component is added to the subnet and placed in a partition to which the OS has access. The subnet manager (SM) initializes and configures the new component that is added and, through the partition manager, associates the component to one or more partitions of the subnet. The SA then notifies the OSs with access to the partition(s) to which the component is associated and that have a right to access the new component that the new component is available to the OS. Following, the OS updates a database of available components to include the new component and establishes communication with the new component.

摘要： A method for routing System Area Network (SAN) packets to multiple partitions within a single end node is provided. A range of Local Identification addresses (LIDs) are assigned to a channel adapter port within the SAN. Lower order bits within the LID are then assigned to select the particular partition in the end node. The Local ID Mask Control (LMC) field is used to assign multiple LIDs to a single port, using those low order bits to then route the message to the appropriate partition in the end node.

摘要： A method in a network computing system for managing a plurality of subnet managers in the network computing system. An identification is received of a set of subnet managers within the plurality of subnet managers. The set of subnet managers is allowed to participate in a master election to select a master subnet manager. Subnet managers other than the set of subnet managers are placed in a dormant state. The master subnet manager is elected from the set of subnet managers through the master election, wherein other subnet managers within the number of subnet managers poll the master subnet manager to allow the other subnet managers to elect a new master subnet manager if the master subnet manager fails.

摘要： A method in a network computing system for managing configuration information for a set of components in a network computing system. The configuration information is stored for the set of components in the network computing system to form stored configuration information. In the depicted examples, the components may be nodes or devices within nodes. Current configuration is obtained in response to a power cycle. The current configuration information is compared with the stored configuration information to form a comparison. The stored configuration information is updated if a difference is present in the comparison. The stored configuration information is used to configure the components when a power cycle occurs.

摘要： A method for managing allocation of network resources within the distributed computer system is provided. Specifically, the network traversal time and the end node response time for requests and/or packets being routed in a switch-connected system area network are utilized to determine the total round trip time for completion of the particular network operation. The sum of the timeout values for all switches that participate in routing the request from a requester (source) to the receptor node (target) is provided to the requester's channel adapter (CA). The time-out values are provided by the switch manufacturer and are sent to a network Subnet Manager (SM) via SM packets (SMP). The timeout values added together represent the SubnetTimeout. The time-out value of the target channel adapter (CA), the ResponseTime, is also provided to the requester. The requester then utilizes one of two timeout equations to calculate the overall response time required for the request to be completed. A timer is started and the elapsed time to complete the request is monitored and compared with the overall response time calculated. When the timer expires before a response is received at the requester, the operation is assumed to have failed and the network resources being utilized by the request may be reallocated to another network operation.
摘要翻译：提供了一种管理分布式计算机系统内网络资源分配的方法。具体地，利用在交换机连接的系统区域网络中路由的请求和/或分组的网络遍历时间和终止节点响应时间来确定完成特定网络操作的总往返时间。参与将请求从请求者（源）路由到接收节点（目标）的所有交换机的超时值的总和提供给请求者的信道适配器（CA）。超时值由交换机制造商提供，并通过SM数据包（SMP）发送到网络子网管理器（SM）。添加的超时值表示SubnetTimeout。目标通道适配器（CA）的超时值ResponseTime也提供给请求者。然后，请求者使用两个超时方程之一来计算请求完成所需的总体响应时间。启动定时器，并监视完成请求的经过时间，并与计算的总响应时间进行比较。当定时器在请求者接收到响应之前到期时，假设该操作已经失败，并且该请求所利用的网络资源可能被重新分配到另一个网络操作。

摘要： A method and apparatus is provided in which Pipelined Packet Transfers (PPT) are implemented. The PPT methodology includes a request phase and a response phase. The PPT request phase involves a PPT request master delivering to a PPT request target a source address, a destination address and an information packet for the interrupt being requested. The PPT response phase involves the PPT request target becoming a PPT response master with the PPT response master delivering to a PPT request master a destination address and a data packet which includes the interrupt processing information. Pipelined Packet transfers (PPT) are ordered in accordance with a predetermined processing priority to improve performance and avoid deadlock.
