The present invention is directed to a system and method of providing an integrated dynamic multipathing filter. A method of providing a data transfer between a host and a target in a network environment may include providing a logical identifier table by an input/output interface. The logical identifier table includes at least one logical identifier suitable for referencing a physical address identifier of a target. Communications between the host and the target are managed by selecting a route by the input/output interface from at least two routes associated with a logical identifier, the at least two routes communicatively coupling the input/output interface to the target so that the host may access the target utilizing the logical identifier.

Integrated dynamic multipathing filter

A circuit comprising a processor and a translation circuit. The processor may be configured to present a first address. The translation circuit may be configured to (i) determine a mask and an offset, (ii) mask the first address to produce a first masked address, (iii) mask a second address to produce a second masked address, (iv) compare the first masked address with the second masked address, and (v) add the offset to the first address to present a third address in response to the first masked address being at least as great as the second masked address.

Address translation circuit for processors utilizing a single code image

An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to obtain a number of service parameters from a network device. The second circuit may be configured to store (i) a first portion of the service parameters in a first group comprising identification parameters, a number of pointers, and a control field and (ii) one or more second portions of the service parameters in one or more second groups, each comprising a communication parameter and a counter. Each of the number of pointers points to a null address or one of the one or more second groups.
