Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 932

US Classification:

713201, 709223

Abstract:

A method and apparatus for use in data processing system for selecting rules to filter data for a tunnel. A request is received to create a tunnel to another data processing system. A granularity of information about the data processing system is identified to form an identified granularity. The identified granularity of the information about the data processing system is used to select a rule, which matches the identified granularity. This rule is placed in a filter, wherein the filter associates data packets with the tunnel.

International Classification:

G06F 15/16

US Classification:

709228, 709226, 709227, 709206

Abstract:

A session bundle allocation capability enables dynamic allocation of bundles of sessions being handled by a network element to modules of the network element (e. g. , modules such as processing modules configured to perform one or more of traffic processing, traffic switching, and like functions). A bundle of sessions may be allocated by associating a plurality of sessions to form thereby a bundle of sessions, and assigning the bundle of sessions to a processing module group including one or more processing modules configured for processing traffic for the sessions of the bundle of sessions. A bundle of sessions may have a bundle identifier associated therewith and may be migrated from a first processing module group to a second processing module group by changing a mapping of the bundle identifier from being associated with the first processing module group to being associated with the second processing module group.

International Classification:

H04L 12/56

US Classification:

370389

Abstract:

Various embodiments provide a method and apparatus for processing incoming packets in an efficient manner. A service ID bitmap indicating available services associated with the user is established. The available services are grouped into service set. Common service set having common set of rules is determined. A user associated with common service set and incoming traffic is identified. The incoming traffic is processed according to the common set of rules indicated by the service ID bitmap. The efficient use of Ternary Content Addressable Memory (TCAM) results in faster search result, lower power consumption and chip footprint among others.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04J 116

US Classification:

370229

Abstract:

A rate based flow and congestion control mechanism for packet communications whereby the acceleration and deceleration of the sending rate is moderated to be responsive to the traffic encountered. The method of the present invention also reduces oscillation in the transmission rate by being responsive to the characteristics of the network traffic and allowing burst intervals to be borrowed on a periodic basis.

James P. Gray - Chapel Hill NC
Frank D. Smith - Chapel Hill NC
Kevin Jeffay - Chapel Hill NC

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 1256

US Classification:

370236

Abstract:

A flow control system for packet transmission networks is centered in the user applications supplying data to the network. Changes in control are responsive to changes in the transmission parameters of the network, measured in the network and transmitted to the user application. The user application specifies desired ranges of Quality of Service parameters and, when the measured network parameters fall outside of the desired range, the user application modifies the transmission strategy to match the available transmission parameters. Measurements of network parameters are made over a pre-selected observation period to average the values of the transmission parameters.

International Classification:

H04L 1266
H04L 2906

US Classification:

370401

Abstract:

In order to more fully support the need to interconnect dissimilar networks, methods and apparatus are set forth which allow a transport gateway between a native (SNA/APPN) network and a mixed or non-native network to preserve the dynamic functions of the native network. The functions of fully dynamic directory and route selection are supported, in addition to the ability to use parallel gateways when connecting a native network to a mixed network. The ability to route information through a gateway from a dependent LU requester in a non-native network to a dependent LU server in a SNA/APPN network is also demonstrated. This allows concatenation of native and non-native networks while maintaining the addressability and accessibility of the native network.

International Classification:

H04W 8/20

Abstract:

This disclosure relates to supporting handling of state information for a stateful network function of a communication network. The network function of the communication network is provided by a network function environment including a set of network function instances configured to provide the network function, a scheduler configured to receive messages of subscribers of the communication network and to distribute the messages to the network function instances for processing by the network functions instances in accordance with the network function, and a state information storage device configured to store state information of the subscribers. The network function instances are configured to temporarily store state information of the subscribers locally at the network function instances while subscribers are associated with the network function instances and to transfer state information of the subscribers to the state information storage device when the subscribers are no longer associated with the network function instances.

Abstract:

The disclosure relates generally to supporting bonded services at non-anchor nodes. A non-anchor gateway device is configured to support service bonding for a user device and communication with an anchor node of the user device. The non-anchor gateway device is configured to associated a set of user device data plane connections of the user device to form a bonded session for the user device where the set of user device data plane sessions includes a first user device data plane connection associated with a first access network and a second user device data plane connection associated with a second access network. The non-anchor gateway device is configured to map user device traffic of the user device between the user device data plane connections of the bonded session and a user device data plane session between the gateway device and the anchor node for the user device.
