    摘要: A method of operating a network subnet manager, in particular Infiniband network subnet manager in a subnet of a network. 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 loses 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 proposed method 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: In the method for management of data transmissions in a network, switching means are provided, by means of which a change can be carried out between a first data transmission type and a second data transmission type, as alternative data transmission types between a transmitter and a receiver. The change is carried out on the basis of at least one respectively predetermined criterion. The first data transmission type corresponds to a transport protocol based on rate-based overload control. The second data transmission type corresponds to a transport protocol based on RTT-based overload control.

    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: 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: 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.
