Appl. No.:

8/352264

Inventors:

Steven M. French - Austin TX
Everett A. McCassey - Florence TX

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15163

US Classification:

39518202

Abstract:

A session-oriented network application dependent on reliable transport of messages on a first system communicates in a new form of connectionless, session-oriented communication called Sideband over a network with a second similar application on a second system. Sideband transport is not guaranteed; Some types of messages and those which are lost must be sent on a reliable, non-Sideband transport. The LAN application contains means to track whether Sideband is both available and enabled on its session with the second application. The application determines whether to disable or reenable the Sideband in its session based on network reliability. As Sideband is fast, but unreliable, the application must be selective about which messages to send Sideband. Messages which would change the state of the receiving system if received twice due to retry of an apparently lost message should not be sent Sideband. The LAN application monitors the responses from the second system to determine whether any messages sent Sideband were lost.

US Classification:

395610

Abstract:

A method for providing files to a remote node including the steps of determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, reserving bandwidth for the requested file if bandwidth is determined to be available, and opening the requested file for transmission only if bandwidth is reserved. In addition, an apparatus for providing files to a remote node including apparatus for determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, apparatus for reserving bandwidth for the requested file if bandwidth is determined to be available, and apparatus for opening the requested file for transmission only if bandwidth is reserved.

US Classification:

39520012

Abstract:

A session-oriented local area network (LAN) application and an ISO 8802-2 protocol driver code will cooperate in a new form of connectionless, session-oriented communication called Sideband. At each session start-up time, the LAN Application will communicate with the enhanced ISO 8802-2 based protocol driver on the local system and the LAN Application and the 8802-2 based protocol driver on the remote system to determine if they all support the Sideband. If Sideband is fully supported by both systems, Sideband will be activated for the session. To communicate on a session which has Sideband active, the LAN Application requests that data is to be sent using the Sideband. A check is performed to see if the data meets Sideband criteria. As Sideband is a connectionless medium, the additional code path needed to set up and track timers and to handle the resend attempts are saved in the protocol. If the LAN Application code is session-oriented, it will keep track of a timer which will cause the data to be resent along a non-Sideband path if a response is not received within a designated amount of time.

International Classification:

G06F 1134

US Classification:

39518213

Abstract:

A system and method for regeneration of certain on disk dynamic control blocks for the file system after failure of access to the control blocks improves auxiliary disk storage system robustness. Regeneration of the dynamic control blocks is achieved without persistent replicas of the blocks on disk and thereby adheres to prior art disk formats. The regeneration control blocks are preferably used to support file system operation during backup of the disk, since loss of access to critical sectors for storing control blocks may portend disk storage system failure.

International Classification:

H04L 12/24

Abstract:

In one embodiment, a device in a network maintains a topology database of one or more topologies of entities in the network. The device identifies a replacement entity that has physically replaced a particular one of the entities in the network. The device determines whether neighbor information regarding one or more of the entities that neighbor the replacement entity matches neighbor information in the topology database associated with the replaced entity. The device determines whether client information regarding one of more clients of the replacement entity matches client information in the topology database associated with the replaced entity. The device sends an alert when the neighbor or client information of the replacement entity does not match the neighbor or client information in the topology database associated with the replaced entity.
