Location-independent references include a live reference containing a location of a remote object and a universally unique identifier (UUID) which provides a unique global reference to that remote object. If a method call to the remote object using the live reference fails, the UUID is used to obtain a new reference to the remote object and the new reference is then used to make another method call. A new reference can be obtained from an identifier directory that contains a mapping between UUIDs and location-independent references. When a remote object is first created, or when a remote object is moved from one location to another, the remote object registers with any and all such directories that it can find in its environment. These registrations are leased; that is, if they are not occasionally refreshed by the remote object which registered them, they are dropped from the directory.

Method and apparatus for generating and using location-independent distributed object references

In one aspect, a computer-implemented method includes generating a workload using at least one schema defined by combinations of ranges of each of at least two attributes. The computer-implemented method also includes receiving a request to provide content. The computer-implemented method further includes provisioning the content based upon the workload.

Resource allocation and modification using statistical analysis

An access server generates a handshake with storage servers resulting in more rapid access to the stored data, for example, video data, by a user. The handshake also results in load balancing effects.

Arrangements and methods for access to stored data

Systems and methods for securing the content integrity of and access to object data and code in a distributed system. Content protecting URLs provide a mechanism for checking code or data transmitted out-of-band. Dynamic permission grants are supported during program execution for code or users unknown prior to runtime.

Systems and methods for providing object integrity and dynamic permission grants

A system consistent with the present invention reduces the number of redundant class descriptors that are sent during remote method calls by using serialization contexts. 'Serialization contexts' are dictionary objects that map a class descriptor to a corresponding integer handle. When possible, the integer handle, rather than the full class descriptor, is passed, saving processing time in RMI calls.
