`
`1 The infringement contentions provided herein are based on information obtained to date and may not be exhaustive. Alacritech's investigation of Intel's infringement is ongoing. Alacritech reserves the right to
`supplement and/or amend these disclosures to identify additional Asserted Claims (P.R. 3-1(a)), to identify additional Accused Instrumentalities (P.R. 3-1(b)), and to further identify where each element of each
`Asserted Claim is found in each Accused Instrumentality (P.R. 3-1(c)), including on the basis of discovery obtained from Intel and from third-parties during the course of this litigation.
`
`2 All infringement contentions set forth herein for any independent patent claims are hereby incorporated by reference into the infringement contentions alleged for any dependent patent claims that depend on such
`independent claims, as if fully set forth therein.
`
`3 The Accused Instrumentalities and associated exhibits discussed and/or cited for any claim herein are representative in all material respects of all other Accused Instrumentalities identified for that claim (e.g.,
`although various servers may have immaterial differences in their hardware, firmware, and/or software configuration, the cited references are believed to be illustrative of all such accused server models).
`
`4 Alacritech's inclusion of any claim preamble in this claim chart should not be interpreted as an admission that the preamble is limiting. Alacritech reserves the right to take the position that the claim preambles are
`limiting or not limiting on a claim-by-claim basis.

`
`The Intel Accused Instrumentalities, as used and tested in connection with a server or computer, are capable of establishing, at a host
`computer, a transport layer connection, including creating a context that includes protocol header information for the connection.
`
`Each of the Intel Accused Instrumentalities constitutes or has an LSO-capable network controller, such as the Intel 82599 10 GbE
`Controller, and is tested and used with a host computer (e.g., a server). See, e.g., "Dell PowerEdge C6320 Rack Server Spec Sheet,"
`BATES ALA00000029-30, describing a server compatable with the Intel Accused Instrumentalities.5

`In connection with infringing LSO functionality, the host computer establishes a transport layer (e.g., TCP) connection, including
`creating a context (e.g., a set of information about the connection) that includes protocol header information for the connection. For
`example, the host computer operating system includes a protocol stack (e.g., a TCP/IP stack) that establishes a TCP connection,
`including creating a context that includes protocol header information for the TCP connection, which the host computer provides to the
`network controller in a pseudo header (also called a prototype header) for the connection. See, e.g., Next Generation TCP/IP Stack in
`Windows Vista and Windows Server 2008, BATES ALA00009427-29 ("Microsoft Stack"), depicting TCP/IP stack and related
`architecture that establishes a TCP connection, including creating a context that includes protocol header information for the TCP
`connection.

`
`feature enables the TCP/IP stack to pass to the network device driver a message to be
`transmitted that is bigger than the Maximum Transmission Unit (MTU) of the medium. It
`is then the responsibility of the device driver and hardware to divide the TCP message
`into MTU size frames that have appropriate layer 2 (Ethernet), 3 (IP), and 4 (TCP)
`headers. These headers must include sequence number, checksum fields, options and
`flag values as required. Note that some of these values (such as the checksum values)
`are unique for each packet of the TCP message, and other fields such as the source IP
`address is constant for all packets associated with the TCP message.
`
`7.2.4.2 Transmission Process
`The transmission process involves the following:
`
`
`• The protocol stack receives from an application a block of data that is to be
`transmitted.
`• The protocol stack calculates the number of packets required to transmit this block
`based on the MTU size of the media and required packet headers.
`• The stack interfaces with the device driver and passes the block down with the
`appropriate header information: Ethernet, IP, optional IPSec and TCP / UDP headers.
`• The stack interfaces with the device driver and commands the driver to send the
`individual packet. The device driver sets up the interface to the hardware (via
`descriptors) for the TCP / UDP segmentation.
`• The hardware transfers (DMA's) the packet data and performs the Ethernet packet
`segmentation and transmission based on offset and payload length parameters in the
`TCP/IP or UDP/IP context descriptor including:
`— Packet encapsulation
`— Header generation and field updates including IPv4/IPv6 and TCP/UDP checksum
`generation.
`• The driver returns ownership of the block of data to the NOS when the hardware has
`completed the DMA transfer of the entire data block.

`
`7.2.4.4 Packet Format
`Typical TCP/IP transmit window size is 8760 bytes (about six full size frames). Today the
`average size on corporate Intranets is 12-14 KB, and normally the maximum window size
`allowed is 64 KB (unless Windows Scaling — RFC 1323 is specified). A TCP / UDP
`message can be as large as 256 KB and is generally fragmented across multiple pages in
`host memory. The 82599 partitions the data packet into standard Ethernet frames prior
`to transmission. The 82599 supports calculating the Ethernet, IP, TCP, and even UDP
`headers, include checksum, on a frame-by-frame basis.

`See also, e.g., Offloading the Segmentation of Large TCP Packets, BATES ALA00009420-24 ("Microsoft LSO"), depicting LSO
`functionality, which is enabled by default in Windows Server, including creating a context that includes protocol header information for a
`TCP connection provided in a template header.

`
`
`The network controller of each of the Intel Accused Instrumentalities comprises an interface device that, in connection with infringing
`LSO functionality, transfers the protocol header information for the TCP connection from the host computer to local memory. For
`example, the network controller DMA transfers the pseudo header (also called a prototype header) containing protocol header
`information from host memory (e.g., host transmit buffers) to the network controller using host-provided descriptors. See, e.g., Sections
`7.2.4.2, 7.2.4.4, 7.2.4.5, 7.2.4.7, 82599 Datasheet, BATES ALA00002071-3136, describing DMA transferring a pseudo header for a
`connection from the host computer to the network controller in connection with infringing LSO functionality.7
