Systems and methods for performing intelligent replication of production data on a source storage device. In certain examples, a full backup of the production data is first performed and stored on a destination system. A journal module on the storage device (e.g., a shared storage device), or on at least one source system, tracks files on the storage device that change during a particular period of time. Following this period, a snapshot is taken of the production data. Upon mounting the snapshot, the replication system uses the journal information to identify modified files, conduct a block-level comparison of only the modified files with corresponding files on the destination system, and identify the particular data blocks that changed. The replication system then replicates only the changed blocks to the destination system. Certain systems further store information indicating a source system time of a known good state of the production data.

Embodiments of the invention provide a system that predicts network events and triggers a pre-emptive response. An example implementation predicts network link failures and creates a change in the network before the failure actually happens by instigating policy-based adjustment of routing parameters. In particular, an embodiment of the invention operates in two phases. In the first phase the historical operation of a network is observed (B.4.2), to determine observed relationships between link or cluster failures that have occurred, and subsequent failures of different links or clusters. From these observed relationships failure rules can be derived (B.4.4) that are then applied to control routing in the network during a second, control, phase. That is, in the second, control, phase, the derived failure rules are applied such that if a link or cluster failure occurs, then from the rules a prior knowledge of what additional links may fail in the next a time period is obtained, and remedial action can then be taken such as routing data traffic away from the links that are predicted to fail (B.4.6).

Computer-assisted procedure (501 / 502) to communicate data in a transportation system (90) that physically transports objects (800) from first to second locations (10, 20). The objects (800) have write / read memory tags (300). Prior to communicating data is separated into meta-data M and content-data C. Communicated are: C on the tags (300), M through a computer network, and type-data T (representing M) on the tags. System computers (901, 902, 900) perform complementary methods for forwarding (501) and retrieving (502).

To retrieve (502) data at the second location (20) where the objects arrive, a second computer (902) reads T from the (300), queries (550) the exchange computer (900) with T for M according to the same table, and reads (560) C from the tags (300).

An error handling apparatus and method, and a computer-readable medium storing a computer program for executing the error handling method are provided. According to the method, in a case where a number of errors in object IP packets that are consecutively detected, each within a first predetermined time since a previous error detection, exceeds a maximum allowable number of errors, communication with a sending node of the erroneous IP packets during a second predetermined time is discontinued. Also, errors can be handled with reference to a cache unit including more than one entry identified by an address of a corresponding erroneous IP packet. Therefore, a network load of a receiving node can be reduced by not transmitting an internet control message protocol (ICMP) packet to a sending node where indiscriminate IP packet manipulations or denial of service (DoS) attacks are suspected during the second predetermined time.

A system for delivering content at varying qualities from a server to multiple client across a network has a server side converter and a client side converter. The server side converter makes unicast requests to a server for representations of content and converts these to multiple representations to be delivered as multicast streams. The client side converter receives a request for content from clients, determines a representation of content to obtain and subscribes to an appropriate multicast stream. The client side then converts the multicast stream back into segments available to a client by unicast request. In this way, data is delivered efficiently across a network from a server side to a client side whilst maintaining compatibility that client devices can issue traditional unicast requests.
