    摘要: A comfortable method and device for searching databases are required. Thus, a database access concept including an interface descriptor is proposed. The interface descriptor may be a XML-file which describes interface categories and database access strategies. The database interface machine may comprise a standard category display method and a standard database access method. The database interface machine can use the definitions contained in the interface descriptor to set up a categorized interface to the database and to perform complete database searches.

    摘要: In the method for operating a multi-port bridge for the routing, differentiated in accordance with traffic classes, of data packets which are subdivided into different priority classes in accordance with the IEEE802.1D standard, an additional traffic class “isochronous channel” is introduced. The multi-port bridge is configured in such a manner that at least one predetermined port in the case of unidirectional transmission and at least one predetermined port pair in the case of bidirectional transmission is operated in the “forwarding” state in which the predetermined port or the predetermined port pair forwards data packets of the additional traffic class IC from a queue. During the forwarding, all ports are deactivated with the exception of the predetermined port or port pair. The isochronous data stream is not restricted to one port or port pair but can be executed several times in dependence on the data rate of the transmission channel.

    摘要: The invention relates to a new type of quality of service architecture for a network assembly and a corresponding computer network system. The Internet technology as approved by the IETF organization has defined different services. One is the integrated services (IntServ) and the other the differentiated services (DiffServ) architecture. Another is the RSVP Protocol according to which Quality of Service can be implemented with accuracy and richer functionality.The invention shows a way how less sophisticated QoS managers inside the network with only DiffServ or Intserv capability, can be used for enhancing the QoS functionality based on so-called RSVP shadowing messages, and easy to implement RSVP shadowing stacks.

    摘要: A method of managing a packet administration map for data packets to be received via a network. A receiver in the network monitors sequence numbers and stores missing sequence numbers within an internal data structure, called a packet administration map. A reversed keying is used which means that the upper limit of the range of contiguous missing data packets is used as the key entry in the administration map.

    摘要: The invention relates to a method of operating a network subnet manager, in particular Infiniband network subnet manager in a subnet of a network.The subnet manager is a software entity with the task of managing, for example Infiniband subnet and can reside on any one node. The subnet manager discovers the topology of the subnet that it manages, assigns a subnet ID to each port, assigns an address to each port in the subnet, establishes the possible path between all end nodes in the subnet, sets QoS parameters and sweeps the subnet on a regular basis looking for topology changes. Only one subnet manager entity can be master within a subnet.A problem related with this specification is that a specific vendor implementation may exist with many features and internal functionality that are not specified in the network specification. If such a subnet manager looses its exclusivity because another subnet manager enters the subnet, having higher priority, the additional features from the vendor implementation can no longer be used in the subnet.The solution according to the invention solves this problem by allowing a subnet manager that has a lower hierarchy level and thus lower priority to maintain its managing operation by becoming the master subnet manager again.

    摘要: A method and apparatus for file access in a storage access network (SAN) wherein a portion of a first file is accessed and an access rate computed based on time and amount of data accessed. If the computed access rate is less than an expected rate, a problem is identified and analysis performed. A first analysis accesses the first file through a second link to determine if the link is the problem. If the first file is accessed at an expected rate, the first link is identified as the problem and the file is accessed through an alternate link. A second analysis accesses a second file through the first link. If the second file is accessed at an expected rate, the first file is identified as the problem and the second file is accessed through the first link.

    摘要: Modern computers (10, 20) come with different timers having different attributes like time resolution, supported time range and time reference. Some are local timers, representing relative time values like the TSC counter (11, 21) counting CPU cycles from the power on or reset of the computer. Some are global timers, representing an absolute or real time. Having different classes of timers in the computer (10, 20), a number of computations need to be performed to tie the different timers to each other.It is the idea of the invention to define a single high resolution timer structure wherein the time value is represented with a digital number and a flag clarifies whether the timer is a global timer or local timer. The invention enables a much faster processing of the time values. The global time, tied to a high-resolution timer can be tracked much faster. This means better precision of scheduling of time critical jobs, like packet scheduling for data transport.
