Abstract: A method of correlating events in a stream of data packets in which each data packet includes an event type identifier and an attribute associated with a type of event. A plurality of data packets of the stream of data packets is received and correlation set of selectors is applied to the received data packets. Each selector of the correlation set of selectors is responsive to data packets of a predetermined type of event to extract the attribute from the data packets. The method further includes assessing two or more data packets of the received data packets as correlating events if attributes extracted from the two or more data packets match. Additionally, the method includes accessing a correlation session in a data store for each correlating events match, the correlation session holding data items of tasks that process said correlating events.

Abstract: In view of the connection of a home network to an external network via a home router, using a mechanism that access from the same network is provided with a source MAC address whereas a source address field is rewritten to a MAC address of the router in the case of external access via the router, whether or not access is made from the home network is automatically identified by comparing a MAC address of a device on the other side of communication with a MAC address of the home router. It is capable of suitably managing so that a client terminal uses the contents legitimately acquired on a home server within the scope of private use allowed by the copyright law.

Abstract: A method, system, and program for managing on-demand email storage are provided. An email service provider allocates a predetermined amount of storage space to an intended recipient. When an email is received for the intended recipient at the email service provider, the email service provider determines whether the predetermined storage space has sufficient capacity for storage of the email. If the predetermined storage space is insufficient for storage of the email, then the email service provider allocates on-demand storage space to the intended recipient. The email service provider then stores the email in the on-demand storage space, such that the email is stored, rather than discarded, when the predetermined storage space reaches full capacity. Before allocating on-demand storage space, the email service provider may compare the email characteristics with predefined criteria set by the intended recipient for emails to be stored in on-demand storage space.

Abstract: A technique determines whether configured logical bandwidth allotments for logical channels are supported by maximum available physical bandwidths of physical channels assigned to those logical channels. The technique establishes a bandwidth-constraint directed acyclic graph (DAG) or “BCD” based on novel relationship rules between vertexes of the BCD that represent logical channels or unions of logical channels as well as the underlying physical channels and their maximum available bandwidth constraints. Once the BCD is established, the vertexes of the BCD may be traversed (e.g., from in-neighbor vertexes to out-neighbor vertexes) to determine whether their constraints are met.

Abstract: Techniques for network-initiated session recovery are described. A relationship is maintained between two identifiers both associated with a session between a first device and an access terminal in a wireless network. The first identifier is associated with the first device, and the second identifier is associated with a second device in communication with the first device. After a breach of the session, communications associated with the session are preserved based on the relationship between the first and second identifiers.

Abstract: A system that services international multimedia message calls includes an MMSC that determines from the destination MSISDN of the header of a multimedia message that the call is an international transmission and, at the same time, determines whether or not the forwarding destination supports number portability, by referencing the MSISDN routing table. If number portability is supported, it acquires the IMSI corresponding to the destination MSISDN by inquiring the HLR. Next, the MMSC acquires the domain name of the MMSE of the forwarding destination by referencing the IMSI routing table from the IMSI that has thus been acquired and forwards the multimedia message to this MMSE. If number portability is not supported, it forwards the multimedia message to the MMSE of the domain name acquired by referencing the MSISDN routing table.
