Abstract: Systems, methods, apparatus and mechanism for maintaining an existing UE control session attachment while changing bearers of a UE data session, such as migrating between UMTS and non-UMTS bearers terminating at a common gateway device.

Abstract: Systems, methods, architectures, mechanisms and/or apparatus to manage routing associated with a redundant pair of nodes during a switchover from an old active node to a new active node by establishing a tunnel there between to convey traffic routed to the old active node prior to routing protocol convergence at the new active node.

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.

Abstract: Method, system and apparatus for identifying and binding together in one session multiple data bearing paths through various access technologies between a Packet Gateway (PGW) and Customer Premises Equipment (CPE) to form thereby a bonded service combining wireless and wireline bearers.

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.

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.

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.

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.
