`
`
`
`
`
`
`
`
`
`
`I, Mahadev Satyanarayanan, hereby declare and state the following:
`
`I.
`
`
`
`
`
`
`
`
`
`
`
`
`
`I am a Professor in the School of Computer Science at the Carnegie
`
`
`
`Mellon University.
`
`
`
`
`
`
`
`I received my Bachelor of Technology in electrical
`
`
`
`
`
`
`
`
`
`
`
`engineering and Master of Technology in Computer Science from the Indian
`
`
`
`
`
`Institute of Technology in Madras, India.
`
`
`
`
`
`
`I was awarded First Class with
`
`
`
`
`
`
`
`
`
`
`
`
`Distinction, the highest honor category, for both my Bachelor and Master degrees.
`
`
`
`
`
`
`
`
`
`
`I obtained my PhD. in Computer Science from Carnegie Mellon.
`
`
`
`
`
`
`
`
`
`
`
`
`
`I have engaged in decades of research at Carnegie Mellon, as well in
`
`,)
`
`
`
`
`
`
`
`
`companies such as IBM, Digital Equipment Corporation and Intel.
`
`
`
`I have
`
`
`
`
`
`
`
`
`
`
`
`participated in system design and development of mobile computing, pervasive
`
`
`
`
`
`
`
`
`computing, and distributed systems, including distributed operating systems.
`
`.1
`
`
`
`
`
`
`
`
`3. My design and development work includes designing enterprise—grade
`
`
`
`
`
`
`
`
`
`
`distributed file systems. For instance, I was a principal architect ofthe Andrew
`
`
`
`
`
`
`
`
`
`
`
`
`
`File System (AF S), which was the first file system to employ scalable file
`
`
`
`
`
`
`
`
`
`caching, security through Access Control Lists, and volume—based system
`
`administration.
`
`
`
`
`
`
`
`
`
`
`
`I leveraged the experience I gained in designing AFS as one of
`
`
`
`
`
`
`
`
`
`
`
`
`
`the principal architects ofthe Coda distributed file system. Coda was the first file
`
`
`
`
`
`
`
`
`
`
`system designed to address problems of disconnected client operation and
`
`
`
`
`
`
`
`
`
`bandwidth—adaptive file synchronization between clients and servers where the
`
`
`
`
`
`
`
`
`
`network connection was intermittently available or low in bandwidth.

`
`
`
`
`
`
`
`Since 1986, l have been on the faculty of the Computer Science
`
`
`
`
`
`Department at Carnegie Mellon University.
`
`

`
`
`
`
`
`
`I have authored two books, as
`
`

`
`
`
`
`well as a chapter in a third book.

`
`
`
`
`
`
`
`
`In addition to publishing, 1 have occupied numerous leadership
`
`
`
`
`
`
`
`
`
`positions in scientific organizations, such as the Institute ofElec-trical and
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`Through my publishing and leadership experience in the IEEE and
`
`
`
`
`
`
`
`
`
`
`
`ACM, 1 have gained familiarity with their publication procedures. The IE-EE and
`
`
`
`
`
`
`
`
`
`
`
`ACM regularly publish numerous journals that are focused on technical topics,
`
`
`
`
`
`
`
`
`
`including many within the field of computer science. These organizations”
`
`
`
`
`
`
`
`
`
`publications are considered highly prestigious and professors, researchers, and
`
`
`
`
`
`
`
`
`
`
`
`
`industry professionals seek to have their research published in IEEE and ACM
`
`
`journals.
`
`7.
`
`
`
`
`
`
`
`
`
`
`
`
`The IEEE and ACM also host conferences and workshops, generally
`
`
`
`
`
`
`
`
`
`
`organized by committees of the organization. The conferences are attended by
`
`
`
`
`
`
`
`
`
`
`academics, researchers, students, and industry professionals having an interest in
`
`
`
`
`
`
`
`
`
`
`
`
`the particular topic. Many months before a conference is held, the committee will
`
`
`
`
`
`
`
`
`
`
`
`
`make an announcement, called a “call for papers,” that solicits topical papers for
`
`
`
`
`
`
`
`
`
`
`
`
`presentation at the conference. A committee receives all the papers that are
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`submitted in response to the call and reviews the content for novelty and potential
`
`
`
`
`
`
`
`
`
`
`
`impact. The committee conditionally selects a certain number (typically about 20-
`
`
`
`
`
`
`
`
`
`
`
`30) for presentation at the conference. The conditionality of the acceptance for
`
`
`
`
`
`
`
`
`
`
`
`
`presentation may be based on the author performing edits requested by the
`
`committee.

`
`
`
`
`
`
`
`
`
`
`
`
`
`Authors have a deadline by which they must make the requested edits
`
`
`
`
`
`
`
`
`
`
`
`
`
`and resubmit their papers. If the committee is satisfied with an author’s edits, the
`
`
`
`
`
`
`
`
`
`
`
`paper is then finally selected for presentation at the conference.
`
`9.
`
`
`
`
`
`
`
`
`
`
`Papers that are selected for presentation are generally collected into a
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`bound “conference proceedings” publication that is distributed to all attendees of
`
`
`
`
`
`
`
`
`the conference. Conference proceedings are typically then sent to libraries that
`
`
`
`
`
`
`
`
`
`
`
`
`have relevant subscriptions from the host organization. Research universities with
`
`
`
`
`
`
`
`
`
`
`computer science departments typically have subscriptions to numerous technical
`
`
`
`
`
`
`
`
`
`journals and receive proceedings publications from many IEEE and ACM
`
`
`conferences.
`
`
`
`
`
`
`
`
`
`
`
`
`
`10. Most conferences hosted by IE-EE and. ACM give awards for the best
`
`
`
`
`
`
`
`
`
`
`
`
`
`papers (often called “best paper” or “outstanding; paper”) to a small subset of
`
`
`
`
`
`
`
`
`
`authors whose papers are presented at the conference. The organizing committee
`
`
`
`
`
`
`
`
`
`
`
`determines which of the presented papers receives an outstanding paper award.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Frequently, the authors of a paper that receives such an award. will be invited to
`
`
`
`
`
`
`
`
`
`
`
`republish that paper in a more prestigious, more frequently published journal of
`
`
`
`the host organization.

`
`
`
`
`
`
`
`
`
`
`
`
`
`“Disconnected Operation in the Coda File System,” which is the paper that was
`
`
`

`
`
`
`
`
`
`
`
`
`
`Systems Principles (“SOSP”) in October 1991. As a paper presented at an ACM
`
`
`
`
`
`
`
`
`
`
`
`
`conference, it followed the submission, acceptance, and publication process that I
`
`
`
`
`
`
`
`
`
`
`
`described above in paragraphs 7-9. The paper was collected, along with the other
`
`
`
`
`
`
`
`
`
`
`
`
`papers presented at SOSP, into a bound volume that was distributed to all
`
`
`
`
`
`attendees of the Symposium.
`
`

`
`
`
`
`1 have maintained a record of the conference
`
`
`
`
`
`
`
`
`
`
`
`
`attendees. According to my records, around 300 people attended the conference.
`
`
`
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`“Disconnected Operation in the Coda File System” was given an
`
`
`
`
`
`
`
`
`
`
`
`
`Outstanding Paper award by the organizing committee of SOSP and was also
`
`
`
`
`
`
`
`
`
`forwarded to ACM’s Transactions on Computer Systems (“TOCS”), ajournal
`
`
`
`
`
`
`
`
`
`
`
`
`which has been published about four times per year since 1983, with a
`
`
`
`
`
`
`
`
`
`
`
`
`recommendation that the paper be published in TOCS as well. The TOC S journal
`
`
`
`
`
`
`
`
`
`
`
`
`
`accepted “Disconnected Operation in the Coda File System" for publication, and
`
`
`
`
`
`
`
`
`
`the paper was published in the February 1992 issue.

`
`
`
`
`“Disconnected Operation in the Coda File System" has been

`
`frequently been an assigned reading in graduate and undergraduate courses
`
`
`
`
`
`
`
`
`
`
`
`dealing with operating system design principles. Even today, the paper continues
`
`
`
`
`
`
`
`
`
`
`
`to be referred to in the classroom and in publications, and still receives praise
`
`
`
`
`
`
`
`
`
`
`
`
`from the research community. For instance, in 2015, “Disconnected Operation in
`
`
`
`
`
`
`
`
`
`
`the Coda File System” was awarded ACM’S Special Interest Group on Operating
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Systems” (“SIGOPS”) “Hall ofFame” award. And in 2016, the paper was given
`
`
`
`
`
`
`
`
`
`
`
`ACM’S Special Interest Group on Mobility of Systems, Users, Data and
`
`
`
`
`
`
`Computing‘s (“SIGMOBILE”) Inaugural “Test—of-Time” Award.
`
`
`
`
`
`
`
`
`
`
`15. After “Disconnected Operation in the Coda File System” received the
`
`
`
`
`
`outstanding paper award at SOSP, professors from a number of universities
`
`
`
`
`
`
`
`
`
`
`contacted me seeking a copy of the paper.
`
`
`
`
`
`
`
`
`
`
`in response to these inquiries, I
`
`
`
`
`
`
`
`
`
`
`emailed copies of the paper to several professors before the publication of the
`
`
`
`
`
`
`
`paper in TOC‘S in February 1992.
`
`
`
`
`
`
`I have examined Exhibit 1006 and it is the
`
`
`
`
`
`
`
`

`
`
`same document that l sent in response to emails requesting a copy of the paper.
`
`

`
`
`
`
`
`
`
`
`
`I distributed and that has been submitted as Exhibit 1006 was a version that was
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`nearly identical to the version published in TOCS, save for three minor
`
`
`
`
`
`
`
`
`
`
`
`differences. First, the version I sent stated the Coda system had successfully
`
`
`
`
`
`
`
`
`
`
`
`
`
`operated while disconnected for “four to five hours.” By the time the TOCS
`
`
`
`
`
`
`
`
`
`
`
`version was published, we had obtained better results and were able to report the
