摘要： The described embodiment provides storage control (PSCF) for overlapping the handling of processor store requests between their generation by an instruction execution means (IPPF) and their presentation to system main storage (MS).The embodiment uses a store counter, an inpointer counter, an outpointer counter, a translator pointer register, an output counter and a plurality of registers sets to process and control the sequencing of all store requests so that the PSCF can output them to MS in the order received from the IPPF. The embodiment uses the counters to coordinate the varying delays in PSCF processing of plural store request contained in different register sets and the translator.The store counter obtains independence between plural IPPF operand address (OA) registers which send the store requests and plural PSCF register sets which handle the store request. The number of OA registers is made independent of the number of register sets. The store counter is also used for serializing instruction control.

摘要： A terminal adapter interfaces between a Data Terminating Equipment (DTE) and either a Frame Relay or a Switched Multimegabit Data Service (SMDS) telecommunications network so that the type of network over which the DTE is communicating is transparent to the DTE. The terminal adapter performs mapping from one protocol to another so that a native frame relay DTE can access an SMDS network and so that a native SMDS DTE can access a frame relay network. The address mapping method performed by the terminal adapter uses a parallel table look-up technique which reduces the chance of collision (when two or more addresses hash into the same table entry), eliminates the traditional comparison function to detect a collision, and eliminates the traditional pointer technique when a collision occurs.

摘要： The system and method of the present invention provide a mechanism, for the purpose of efficiently interconnecting local area networks (LANs) across a frame relay network, by which LAN stations provide data flow control when the frame relay network becomes congested. The system of the invention comprises a Station Manager at the network end point internetworking unit (IWU) for managing the IWU, a LAN Manager for managing one or more LANs connected to the end point IWU, and Station Managers at each of the LAN stations managing the respective LAN station. In operation, the IWU receives from the frame relay network a congestion notification and the IWU Station Manager broadcasts this notification to its managed LAN station Station Managers. The LAN station Station Managers each examine the notification against its outstanding data to be transmitted and slows down data traffic that is destined for the congested portion of the frame relay network.

摘要： The system and method of the present invention provide a seamless approach for providing ATM connectivity for a Frame Relay DTE using an intelligent Terminal Adapter (TA). Using the system and method of the present invention, an enhanced Frame Relay protocol runs between the DTE and the ATM TA, the Frame Relay DTE is provided with not only the connectivity to the ATM network but also the full advantages of ATM transport mechanism. For instance, the FR DTE can choose to transmit its data using ATM Adaptation Layer (AAL) 1,3/4 or 5. Using the system and method of the present invention, a FR DTE may communicate with another FR DTE or to an ATM DTE through wide area or local area ATM network. The Frame Relay DTE can send data, image, voice, or video traffics across the ATM network via the FR/ATM terminal adapter.

摘要： A method and apparatus for protecting the integrity of data in a multi-loop communication network is disclosed. A source station generates and forwards a frame with a unique format and a frame check sequence (FCS). At each bridge, an algorithm is provided to process the frame. If the frame is at a source bridge and not discarded, the FCS is preserved by encapsulating it in the Information field. The source bridge generates a new FCS, appends it to the frame and forwards the frame. Thereafter, each intermediate bridge generates its own FCS, appends it to the frame and forwards the frame. At the target bridge, no FCS is generated. The preserved FCS is forwarded as the FCS of the frame.

摘要： To efficiently diagnose local and remote adapters without using dedicated hardware in a communication network to which a plurality of terminals are connected through associated adapters, a local logical address which is different from logical addresses reserved for communication between the terminals, is assigned to communication with a local adapter, and a frame including the local logical address and a diagnostic command is transmitted to the local adapter. When a remote adapter is to be diagnosed, a frame including a logical address assigned to communication with a remote terminal associated with that remote adapter, a diagnostic command, and at least one invalid character, is sent out from the local adapter to the network.

摘要： The system and method of the present invention provide a seamless approach for providing ATM connectivity for a Frame Relay DTE using an intelligent Terminal Adapter (TA). Using the system and method of the present invention, an enhanced Frame Relay protocol runs between the DTE and the ATM TA, the Frame Relay DTE is provided with not only the connectivity to the ATM network but also the full advantages of ATM transport mechanism and, in particular, the connectivity through the ATM network using the SVC connection mechanism. Using the system and method of the present invention, a FR DTE may issue commands to the terminal adapter to set of calls, or connections, with other DTEs (FR or ATM). The terminal adapter then communicates with the ATM network and the destination DTE using the ANSI Q.2931 call establishment procedure (using commands such as Call.sub.-- Set-up, Call.sub.-- Accept, and Call.sub.-- Disconnect) to establish an SVC connection between the communicating DTEs. In addition, the FR DTE sends parameters such as quality of service (QOS), peak bandwidth, etc., so that the Frame Relay DTE can send real-time data, image, voice, or video traffics across the ATM network using the less expensive SVC mechanism.

摘要： The architecture provides a frame format and procedure for routing messages through a single ring or multi-ring communication system. Stations associated with the exchange of messages are located on the single ring or on different rings of the multi-ring communication system. The rings are connected by bridges to form a local area network. The frame format includes a plurality of control bits positioned within a Routing Information (RI) field, a frame control field and a frame status field. Messages are generated and structured in accordance with the frame format. A group of the control bits, in each message, is set with initial values according to the message type. Thus, different messages are characterized by a different sequence of control bit settings. A routing algorithm analyzes the message and depending on the status of the control bits, the message is processed and ultimately switched to its proper destination.

摘要： The disclosed embodiments filter out many unnecessary interrogations of the cache directories of processors in a multiprocessor (MP) system, thereby reducing the required size of the buffer invalidation address stack (BIAS) with each associated processor, and increasing the efficiency of each processor by allowing it to access its cache during the machine cycles which in prior MP's had been required for invalidation interrogation. Invalidation interrogation of each remote processor cache directory may be done when each channel or processor generates a store request to a shared main storage.A filter memory is provided with each BIAS in the MP. The filter memory records the cache block address in each invalidation request transferred to its associated BIAS. The filter memory deletes an address when it is deleted from the cache directory and retains the most recent cache access requests.The filter memory may have one or more registers, or be an array. Invalidation interrogation addresses from each remote processor and from local and/or remote channels are received and compared against each valid address recorded in the filter memory. If they compare unequal, the received address is recorded in the filter memory as a valid address, and it is gated into BIAS to perform a cache interrogation. If equal, the inputted address is prevented from entering the filter memory or the BIAS, so that it cannot cause any cache interrogation. Deletion from the filter memory is done when the associated processor fetches a block of data into its cache. Deletion may be of all entries in the filter memory, or of only a valid entry having an address equal to the block fetch address in a fetch address register (FAR). Deletion may be done by resetting a valid bit with each entry.
