US Patent:

61222895, Sep 19, 2000

Filed:

Aug 29, 1997

Appl. No.:

8/920974

Inventors:

Patrick G. Brown - Raleigh NC
Kimi A. Cousins - Apex NC
John R. Flanagan - Poughkeepsie NY
Maurice Isrel - Raleigh NC
Balachandar Rajaraman - Cary NC
Arthur J. Stagg - Raleigh NC

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04J 316

US Classification:

370465

Abstract:

Methods, systems (apparatus) and computer program products are provided that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter. The control of the data rate may be accomplished by assigning to guaranteed bandwidth connections, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. Guaranteed bandwidth connections are then limited to this amount of data in a time interval. Furthermore, an outbound data threshold for data sent tot he adapter and a total data threshold for data to or from the adapter may be established and best efforts data not sent to the adapter if either of these thresholds are exceeded within the time interval.

US Classification:

370235

Abstract:

Methods, systems (apparatus) and computer program products that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter are provided. The data rate is controlled by assigning to the guaranteed bandwidth connection, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. The amount of data transmitted through the communications adapter for the guaranteed bandwidth connection is then counted so as to provide a connection data count associated with the guaranteed bandwidth. Data transmitted for the communications adapter associated with the guaranteed bandwidth connection is not transmitted to the communications adapter if transmission of the data would cause the connection data count to exceed the maximum threshold value assigned to the guaranteed bandwidth connection. The connection data count is then reset after expiration of the time interval.

Appl. No.:

16/801291

Inventors:

- Armonk NY, US
Mooheng Zee - Dutchess NY, US
John R. Flanagan - Chapel Hill NC, US
Christopher J. Colonna - Ossining NY, US

International Classification:

H04L 9/08
H04L 29/08
H04L 29/06

Abstract:

Aspects of the invention include receiving a request from an initiator channel on an initiator node to initiate a secure communication with a responder channel on a responder node. The receiving is at a local key manager (LKM) executing on the initiator node. A security association is created at the LKM between the initiator node and the responder node. An identifier of a shared key assigned for communication between the initiator node and the responder node is obtained, and a message requesting initialization of the secure communication between the initiator channel and the responder channel is built. The message includes the identifier of the shared key. The message is sent to the initiator channel.

H04L 29/06

Abstract:

Aspects of the invention include generation of a secure key exchange (SKE) authentication response by a responder node of a computing environment. A computer-implemented method includes receiving an authentication request message at a responder channel on the responder node from an initiator channel on an initiator node to establish a secure communication, the receiving at a local key manager (LKM) executing on the responder node. A state check is performed based on a security association of the initiator node and the responder node. A validation of the authentication request message is performed. A proposal list of the authentication request message is checked. An authentication response message is built based at least in part on a successful state check, a successful validation, and selecting an encryption algorithm from the proposal list. The authentication response message is sent from the LKM to the responder channel.
