摘要： The invention includes a method and apparatus for use with a system including networked resources where communication between resources is via a dual packet protocol wherein a first protocol includes a frame that specifies a destination device/resource and a data field and the second protocol specifies a final destination device/resource and includes a data field and where the second packets are encapsulated in the first protocol packet frames the method including the steps of specifying access control information for resources, for each first protocol packet transmitted on the network, intercepting the first protocol packet prior to the first protocol destination resource, examining at least a subset of the additional embedded packet information to identify at least one of the intermediate path resources and the final destination resource, identifying the access control information associated with the identified at least one of the intermediate path resources and the final destination resource and restricting transmission of the first protocol packet as a function of the identified access control information.
