5、53A High Speed Network for MIL-STD-1760 RATIONALEThe AS5653A standard defined a High Speed Fibre Channel Network to improve the capability of MIL-STD-1760 to transfer information. That activity was initiated at the request of the US Navy in 2001. This standard AS5653B - is a followup to AS5653A init
6、iated to correct some technical issues discovered in AS5653A as well as to include some additional useful features. This revision completely replaces the previous AS5653A version. FOREWORDAS5653 makes extensive reference to Fibre Channel standards. In the context of the MIL-STD-1760 interfaces, AS56
7、53 is referred to as a “bus”. In the context of Fibre Channel, AS5653 is referred to as a “network”. To aid comprehension of AS5653 explanatory text is included, as illustrated below.

15、OPE AS5653 may be applied to Air Vehicles and Stores implementing MIL-STD-1760 Interface Standard for Aircraft/Store Electrical Interconnection System. 1.1 Purpose This standard defines the characteristics and requirements for a high speed data bus incorporated within a MIL-STD-1760 interface to pro
16、vide improved transfer capabilities and an alternative command and control path. The high speed data bus is based on Fibre Channel standards. This document (AS5653) is a profile of Fibre Channel standards. This standard identifies the network topology in examples. Supported topologies include Fabric
17、 Switched and Point-to-point. The Fibre Channel Arbitrated Loop topology is prohibited.This standard contains the minimum interoperability requirements necessary to define a standardized transport mechanism for video, audio, data files, and command and control transfers. This standard assumes knowle
18、dge of Fibre Channel communication concepts - reference should be made to the Fibre Channel standards where appropriate. 2.

28、itions The following definitions are used in Fibre Channel profiling documentation and are adopted for consistency. REQUIRED: If a feature or parameter value is Required, it means that it shall be used between compliant implementations. Compliant implementations are required to implement the feature
29、. Interoperability is not guaranteed if Required features are not implemented.INVOCABLE: If a feature or parameter value is Invocable, it means that compliant implementations are required to implement the feature. Invocable is different than Required in that an implementation may invoke (i.e., use)
30、the feature if needed, but it is not required to invoke it.ALLOWED: If a feature or parameter value is Allowed, it means that it may be used between compliant implementations. Compliant implementations are not required to implement the feature. Typically, the potential user of an Allowed feature may
31、 determine if an implementation supports it via an Invocable discovery process.PROHIBITED: If a feature is Prohibited, it means that it shall not be used between compliant implementations. Table 2 summarizes the above definitions. TABLE 2 - SUMMARY OF IMPLEMENTATION AND USE OF FEATURES Term Implemen
32、tation Use Required Shall Shall Invocable Shall May Allowed May May Prohibited May Shall Not These definitions are re-used from Fibre Channel to give a consistent approach.

GENERAL REQUIREMENTS 3.1 Port
38、 Designation The ports shall provide 1.0625 Gbaud Fibre Channel Port functionality as defined in FC-FS-2 and FC-SW-4 and allocated in Table 3. Examples are given in Figures 1 and 2.

39、 Functionality ASI AE_Port or F_Port or N_Port MSI N_Port CSI AE_Port or N_Port CSSI AE_Port or F_Port or N_Port A Fibre Channel Port may be capable of multiple functionalities. The functionality used depends upon the initialization sequence followed, and is determined by responses to link initializ
40、ation commands. After initialization, a Fibre Channel port has a single functionality. In this profile, an ASI connected to an MSI is an F-port or N_Port, and an ASI connected to a CSI is an AE_Port or N_Port. The same logic applies for a CSSI.
