摘要： An article of manufacture, an apparatus, and a method for processing packets in a peripheral component interconnect express (PCIe) network. An article of manufacture includes a computer program product that includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a PCIe posted write packet at a receiving device, the PCIe posted write packet including a received tag identifier and a requesting device identifier identifying a requesting device. An expected tag identifier is determined for the requesting device. The received tag identifier is compared to the expected tag identifier. An error flag is set if the received tag identifier does not match the expected tag identifier.

摘要： A time division multiplexing (TDM) facility is presented for time division multiplexing at least two inter-system channel (ISC) data streams to create a TDM multiplexed data stream. The TDM multiplexed data stream can be forwarded across the network over a single wavelength of a wavelength division multiplexing (WDM) network. The TDM multiplex data stream may be wavelength division multiplexed with one or more other TDM multiplexed data stream. Different protocols are presented for maintaining disparity balance within the ISC data streams depending upon whether a given sequence in one of the data streams is an idle sequence, frame sequence or continuous sequence.

摘要： Performance counters are provided for virtualized network interfaces of communications networks, while minimizing the use of hardware resources. A virtualized network interface includes physical resources, as well as logical resources. Dedicated performance counters are provided for the physical resources of the virtualized network interface, as well as for logical partitions coupled to that interface, while non-dedicated performance counters are provided for the logical resources. This enables the provision of performance counters for virtualized network interfaces, while minimizing hardware resources consumed by those interfaces.

摘要： Communication over a computer network with a node having a first port with a point-to-point link connection to a second node having a second port. The first port transmits to the second port a reliable link layer (RLL) packet over the link. The RLL packet comprises a first RLL header and a first data packet, the first RLL header preceding the first data packet, the first RLL header comprising an RLL start-of-frame (SOF) character and an RLL packet sequence number (PSN). If the first port receives an RLL acknowledgment control packet from the link, it acknowledges receipt of the first data packet, and the first port does not retain the first data packet in the buffer. If the first port does not receive the RLL acknowledgment packet from the link, acknowledging receipt of the first data packet, the first port re-transmits from the buffer the first data packet.

摘要： A method, system, and computer program product for two-sided, dynamic cache injection control are provided. An I/O adapter generates an I/O transaction in response to receiving a request for the transaction. The transaction includes an ID field and a requested address. The adapter looks up the address in a cache translation table stored thereon, which includes mappings between addresses and corresponding address space identifiers (ASIDs). The adapter enters an ASID in the ID field when the requested address is present in the cache translation table. IDs corresponding to device identifiers, address ranges and pattern strings may also be entered. The adapter sends the transaction to one of an I/O hub and system chipset, which in turn, looks up the ASID in a table stored thereon and injects the requested address and corresponding data in a processor complex when the ASID is present in the table, indicating that the address space corresponding to the ASID is actively running on a processor in the complex. The ASIDs are dynamically determined and set in the adapter during execution of an application in the processor complex.

摘要： Dropped packets are recovered in a link layer of a Data Center Ethernet (DCE) network. Data packets for transmission are stored in a replay buffer. Each data packet includes a header having a field including data indicating that the data packet is formatted for reliable recovery at the link layer. The data packets are transmitted to a receiver across a link layer in the DCE network. The receiver determines whether a data packet has been dropped. If a data packet has not been dropped, an acknowledgement signal is sent to the transmitter in another data packet across the link layer, indicating that the data packet has been received. If a data packet has been dropped, a non-acknowledgement signal is sent to the transmitter in the other data packet across the link layer, indicating that the data packet has been dropped. In response to receipt of the non-acknowledgement signal or no receipt of an acknowledgement signal after the timeout period, the dropped data packet is retrieved from the replay buffer and is resent to the receiver across the link layer.
