ABSTRACT:
A router comprising a plurality of elements, each having an element identifier, subdivided into a plurality of groups of at least one element. Each group has a common identifier and each member within each group shares redundant capabilities. Each element is capable of communicating with another element by addressing information to the common identifier instead of the element identifier. Optionally, one element can be a member of more than one group. Another option suggests that all elements within a group share essential information associated with a service provided by the group. Another option is implemented through one element of the router identifying a primary element for a group, wherein the primary element serves requests addressed the corresponding common identifier. Yet another option suggests that one element is identified through configuration of the router as a primary element in its group to serve requests addressed to the common identifier.
