Mobile IP bulk registration revocation

A computer implemented method in a mobile agent for revoking services to a first mobile node and a second mobile node, the method comprising:

• a first mobile agent of a mobile IP network receiving a single registration revocation message to a second mobile agent of the mobile IP network, the single registration revocation message including information identifying at least two home IP addresses of the first mobile node and information identifying at least two home IP addresses of the second mobile node, wherein registrations of the first mobile node and the second mobile node are to be revoked;
• in response to the registration revocation, the first mobile agent terminating bindings of services associated with the first and second mobile nodes identified by the multiple home IP addresses and sending an acknowledgement message to the second mobile agent,
• negotiating between the first agent and the second agent to indicate whether both the first agent and second agent support a bulk revocation, wherein a bulk revocation is performed only if both the first and second agents support the bulk revocation, and
• setting a bit field in a revocation support extension associated with at least one of a registration request and a registration reply message to indicate whether a specific node that sends at least one of a registration request and a registration reply message supports the bulk revocation.

A non-transitory tangible machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor perform a method in a mobile agent for revoking services to a first mobile node and a second mobile node, the method comprising:

• a first mobile agent of a mobile IP network receiving a single registration revocation message from a second mobile agent of the mobile IP network, the single registration revocation message including information identifying at least two home IP addresses of the first mobile node and information identifying at least two home IP addresses of the second mobile node, wherein registrations of the first mobile node and the second mobile node are to be revoked;
• and
• in response to the registration revocation, the first mobile agent terminating bindings of services associated with the first and second mobile nodes identified by the multiple home IP addresses and sending an acknowledgement message to the second mobile agent,
• negotiating between the first agent and the second agent to indicate whether both the first agent and second agent support a bulk revocation, wherein a bulk revocation is performed only if both the first and second agents support the bulk revocation, and
• setting a bit field in a revocation support extension associated with at least one of a registration request and a registration reply message to indicate whether a specific node that sends at least one of a registration request and a registration reply message supports the bulk revocation.

A computer implemented method performed by a mobile agent for revoking services to a first mobile node and a second mobile node, the method comprising:

• a first mobile agent of a mobile IP network sending a single registration revocation message to a second mobile agent of the mobile IP network, the single registration revocation message including an address range field to specify a range of home IP addresses associated with the first mobile node and information identifying a range of home IP addresses associated with the second mobile node, wherein registrations of the first mobile node and the second mobile node are to be revoked and wherein the registration revocation message causes the second mobile agent to terminate bindings of services associated with the first and second mobile nodes identified by the multiple home IP addresses;
• receiving an acknowledgement message from the second mobile agent indicating that the bindings of services associated with the first and second mobile nodes have been terminated by the second mobile agent;
• negotiating between the first agent and the second agent to indicate whether both the first agent and second agent support a bulk revocation, wherein a bulk revocation is performed only if both the first and second agents support the bulk revocation;
• and
• setting a bit field in a revocation support extension associated with at least one of a registration request and a registration reply message to indicate whether a specific node that sends at least one of a registration request and a registration reply message supports the bulk revocation.
