`
`4.2.1. Layers and Sessions
`The following conceptual layering model is used to specify initiator
`and target actions and the way in which they relate to transmitted
`and received Protocol Data Units:
`- The SCSI layer builds/receives SCSI CDBs (Command Descriptor
`Blocks) and passes/receives them with the remaining Execute
`Command [SAM2] parameters to/from
`- the iSCSI layer that builds/receives iSCSI PDUs and
`relays/receives them to/from one or more TCP connections; the
`group of connections form an initiator-target "session".
`Communication between the initiator and target occurs over one or
`more TCP connections. The TCP connections carry control messages,
`SCSI commands, parameters, and data within iSCSI Protocol Data Units
`(iSCSI PDUs). The group of TCP connections that link an initiator
`with a target form a session (equivalent to a SCSI I_T nexus; see
`Section 4.4.2). A session is defined by a session ID that is
`composed of an initiator part and a target part. TCP connections can
`be added and removed from a session. Each connection within a
`session is identified by a connection ID (CID).
`Across all connections within a session, an initiator sees one
`"target image". All target-identifying elements, such as a LUN, are
`the same. A target also sees one "initiator image" across all
`connections within a session. Initiator-identifying elements, such
`as the Initiator Task Tag, are global across the session, regardless
`of the connection on which they are sent or received.

`iSCSI targets and initiators MUST support at least one TCP connection
`and MAY support several connections in a session. For error recovery
`purposes, targets and initiators that support a single active
`connection in a session SHOULD support two connections during
`recovery.

`Datasheet"), at Sections 1.4.4.1, 7.11, describing interaction between the network controller and the host computer's protocol stack in
`connection with infringing RSC functionality.6
`
`1.4.4.1 Receive Side Coalescing (RSC)
`RSC coalesces incoming TCP/IP packets into larger receive segments. It is the inverse
`operation to TSO on the transmit side. It has the same motivation, reducing CPU
`utilization by executing the TCP/IP stack only once for a set of received Ethernet packets.
`
`The 82599 can handle up to 32 flows per port at any given time. See Section 7.11 for
`more details on RSC.
`7.11 Receive Side Coalescing (RSC)
`The 82599 can merge multiple received frames from the same TCP/IP connection
`(referred to as flow in this section) into a single structure. The 82599 does this by
`coalescing the incoming frames into a single or multiple buffers (descriptors) that share a
`single accumulated header. This feature is called RSC. Note that the term Large Receive
`is used to describe a packet construct generated by RSC.
`
`The 82599 digests received packets and categorizes them by their TCP/IP connections
`(flows). For each flow, hardware coalesces the packets as shown in Figure 7-41 and

`Figure 7-42 (the colored parameters are explained in the RSC context table and receive
`descriptor sections). The 82599 can handle up to 32 concurrent flows per LAN port at any
`given time. Each flow handled by RSC offload has an associated context. The 82599
`opens and closes the RSC contexts autonomously with no need for any software
`intervention. Software needs only to enable RSC in the selected receive queues.
`
`Figure 7-41 shows a top level flow diagram that is used for RSC functionality. The
`following sections provide a detailed explanation of this flow as well as the memory
`structures and device settings that support the RSC functionality.
`
`See also, e.g., Receive Segment Coalescing, BATES ALA00009425-26 ("Microsoft RSC"), describing RSC functionality, which is
`enabled by default in Windows Server.
`
`RSC is a stateless offload technology that helps reduce CPU utilization for network processing on the receive
`side by offloading tasks from the CPU to an RSC-capable network adapter. CPU saturation due to
`networking-related processing can limit server scalability. This problem in turn reduces the transaction rate,
`raw throughput, and efficiency. RSC enables an RSC-capable network interface card to do the following:
`
` Parse multiple TCP/IP packets and strip the headers from the packets while preserving the payload of
`each packet.
`Join the combined payloads of the multiple packets into one packet.
`
` Send the single packet, which contains the payload of multiple packets, to the network stack for
`subsequent delivery to applications.
`
`The network interface card performs these tasks based on rules that are defined by the network stack
`subject to the hardware capabilities of the specific network adapter. This ability to receive multiple TCP

`segments as one large segment significantly reduces the per-packet processing overhead of the network
`stack. Because of this, RSC significantly improves the receive-side performance of the operating system (by
`reducing the CPU overhead) under network I/O intensive workloads.
`
`Here are some key facts about RSC:
`
` RSC is enabled by default for clean installations of all editions of Windows Server 2012 on computers
`that have RSC-capable network adapters. You do not need to take any action to enable RSC when you
`have an RSC-capable network interface card installed in your physical computer or used by a virtual
`machine that is running Windows Server 2012. In addition, you can track RSC status and usage by
`using relevant Performance Monitor counters.
`
`Each of the Wistron Accused Instrumentalities that includes a non-Intel network controller also supports RSC functionality.7 On
`information and belief, each of the non-Intel controllers performs infringing RSC functionality in substantially the same manner as the
`Intel controllers, including with respect to interacting with the host computer's protocol stack with a session layer portion.
`
`[205.1b] and a network interface device
`coupled to the host computer,
`
`The Wistron Accused Instrumentalities comprise a network interface device coupled to the host computer.
`
`Each of the Wistron Accused Instrumentalities comprises at least one RSC-capable network controller, such as the Intel 82599 10 GbE
`Controller, that is coupled to the host computer and that supports session layer protocols (e.g., iSCSI). See, e.g., "CA AppLogic and

`(P.R. 3-1(b)-(c))
`information and belief, each of the non-Intel controllers of the Wistron Accused Instrumentalities performs infringing RSC functionality
`in substantially the same manner as the Intel controllers, including with respect to accelerating iSCSI traffic through performance of
`infringing RSC functionality.
`
`[205.1c] the network interface device
`receiving from outside the apparatus a
`response to a solicited read command,
`the solicited read command being of the
`session layer protocol,
`
`The Wistron Accused Instrumentalities comprise a network interface device coupled to the host computer, the network interface device
`receiving from outside the apparatus a response to a solicited read command, the solicited read command being of the session layer
`protocol.
`
`The network controller of each of the Wistron Accused Instrumentalities receives responses from outside the apparatus to solicited read
`commands of the session layer protocol (e.g., iSCSI). For example, when the host computer sends an iSCSI solicited read request
`command via the network controller to another device located outside the apparatus (e.g., another server on the network), the network
`controller receives a response (the requested data) from the external device, just as it receives all of the host computer's network traffic.
`See, e.g., Sections 1.2.5, 7.1, 82599 Datasheet, BATES ALA00002071-3136, describing functionality for receiving data from a
`network.11
`
`1.2.5 Network Interfaces
`The 82599 interfaces the network through the Multi-Speed Attachment Unit Interface
`also referred to as the MAUI interface.
`
`7.1 Receive Functionality
`Packet reception consists of:
`
`• Recognizing the presence of a packet on the wire
`
`
`converged network adapter (ALA00007595-ALA00007597); Q-Logic 57800S quad-port SFP+/ BASE-T (2x10GbE + 2x1GbE) rack converged NDC (ALA00007583-
