Transferring system identities
First Claim
1. A method of transferring a host identity between a first host system and a second host system, wherein a host identity can belong to only one host system at a time, the method comprising:
- i) designating the second host system as a destination host system for the host identity;
ii) the first host system encoding the host identity to be transferred using a parameter;
iii) the first host system divulging the result of the encoding and removing the host identity from its repository;
iv) the second host system, which also includes a host identity repository, decoding the host identity to be transferred using the parameter, and adding the host identity to be transferred to its repository.

Abstract
First and second host systems can each include a respective repository of host identities. The first host system can encode a host identity to be transferred to the second host system using a parameter, for example a property of the second host system. The first host system can divulge the result of the encoding and remove the host identity from its repository. The second host system can decode the host identity to be transferred using the parameter, and can then add the host identity to be transferred to its repository.

17. A method of transferring a host identity between a first host system and a second host system, wherein a host identity can belong to only one host system at a time, the method comprising:
-
a) in a first phase, i) an administrator system designating itself as an intermediate destination for the host identity to be transferred, ii) the first host system, which includes a host identity repository, encoding the host identity to be transferred using a first parameter, iii) the first host system divulging the result of the encoding and removing the host identity from its repository, and iv) the administrator system decoding the host identity to be transferred using the first parameter, and buffering the host identity to be transferred; and
b) in a second phase, i) the administrator system designating the second host system as a destination for the host identity to be transferred, ii) the administrator system encoding the host identity to be transferred using a second parameter, iii) the administrator system divulging the result of the encoding and removing the host identity from its buffer, and v) the second host system, which also includes a host identity repository, decoding the host identity to be transferred using the second parameter, and adds the host identity to be transferred to its repository.

19. A computer system comprising a first host system and a second host system, wherein:
-
the first host system comprises a host identity repository;
the second host system comprises a host identity repository;
a host identity can belong to only one host system at a time;
the first host system is operable, in response to the second host system being designated as a destination host system for a host identity to be transferred, to encode the host identity to be transferred using a parameter, and to divulge the result of the encoding and to remove the host identity from its repository; and
the second host system is operable, when presented with the encoded host identity, to decode the host identity using the parameter, and to add the host identity to be transferred to its repository. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A computer system comprising an administrator system, a first host system and a second host system, wherein:
-
the first host system comprises a host identity repository;
the second host system comprises a host identity repository;
a host identity can belong to only one host system at a time; and
wherein the system is operable, in order to transfer a host identity from the first host system to the second host system such that;
a) in a first phase, i) the administrator system designates itself as an intermediate destination for the host identity to be transferred, iv) the first host system encodes the host identity to be transferred using a first parameter, v) the first host system divulges the result of the encoding and removes the host identity from its repository, and vi) the administrator system decodes the host identity to be transferred using the first parameter, and buffers the host identity to be transferred; and
b) in a second phase, i) the administrator system designates the second host system as a destination for the host identity to be transferred, v) the administrator system encodes the host identity to be transferred using a second parameter, vi) the administrator system divulges the result of the encoding and removes the host identity from its buffer, and vii) the second host system decodes the host identity to be transferred using the second parameter, and adds the host identity to be transferred to its repository.

36. A computer system comprising first host and second host to which can be allocated a host identity, wherein a host identity can belong to only one host at a time, the computer system comprising:
-
means for designating the second host as a destination for a host identity to be transferred;
means for encoding, at the first host, the host identity to be transferred with a parameter, means for divulging the result of the encoding and means for removing the host identity from repository means of the first host;
means for decoding, at the second host, the host identity to be transferred using the parameter, and means for adding the decoded host identity to repository means of the second host.

37. A computer readable medium comprising instructions for causing a host identity to be transferred between a host systems, where a host identity can belong to only one host system at a time, the instructions being operable to cause, in response to designation of a destination host system for the host identity:
-
i) a source host system for the host identity to encode the host identity to be transferred using a parameter, to divulge the result of the encoding and to remove the host identity from a repository of the source host system; and
ii) the destination host system to decode the host identity to be transferred using the parameter, and to add the host identity to be transferred to a repository of the destination host system.
