`
`·1· · · · · · · · · ·MARK CROVELLA
`
`·2· · · Q.· I'm going to direct you to the first
`
`·3· ·sentence where it says, "A CDN edge server
`
`·4· ·is configured to provide one or more
`
`·5· ·extended content delivery features on a
`
`·6· ·domain specific, customer specific basis,
`
`·7· ·preferably using configuration files that
`
`·8· ·are distributed to the edge servers using a
`
`·9· ·configuration system."
`
`10· · · · · · ·Do you see that?
`
`11· · · A.· Yes.
`
`12· · · Q.· What does it mean, the term "domain
`
`13· ·specific, customer specific basis"?
`
`14· · · A.· So in this document, the Devanneaux
`
`15· ·document, as I analyzed it, the phrase
`
`16· ·"domain specific, customer specific"
`
`17· ·referred to actions that were taken with
`
`18· ·respect to the domain or host name within a
`
`19· ·request for the customer associated with the
`
`20· ·request.
`
`21· · · Q.· So when you -- I think you said the
`
`22· ·word "host name"; is that correct?
`
`23· · · A.· Uh-huh.
`
`24· · · Q.· Would an example of a host name be
`
`25· ·www.Amazon.com?

`
`·2· · · A.· Yes.
`
`·3· · · Q.· And when it talks about "customer
`
`·4· ·specific," what does that mean?
`
`·5· · · A.· In the context of this patent, and,
`
`·6· ·again, as I analyzed it, this phrase is used
`
`·7· ·to refer to actions that are taken with
`
`·8· ·respect to the customer associated with
`
`·9· ·content that's being served by the CDN.
`
`10· · · Q.· Okay.· So if I were sitting at my
`
`11· ·computer and I type in the URL that includes
`
`12· ·www.Amazon.com, what would happen next if
`
`13· ·I'm on the internet?
`
`14· · · · · · ·MR. ROWAN:· Objection to form.
`
`15· · · A.· Well, the complete set of actions that
`
`16· ·would occur next is very detailed, and many,
`
`17· ·many things will happen.
`
`18· · · · · · ·I don't know how much detail you'd
`
`19· ·like me to go into.
`
`20· · · Q.· Would there be a connection to a
`
`21· ·server?
`
`22· · · A.· A connection, one or more connections
`
`23· ·to servers would be made.
`
`24· · · Q.· Okay.· And can I call what is
`
`25· ·occurring a request to a server?

`
`·2· · · · · · ·MR. ROWAN:· Objection to form.
`
`·3· · · A.· In the context of the Devanneaux
`
`·4· ·patent, and as I analyzed it, request to
`
`·5· ·servers -- requests, I just want to say
`
`·6· ·requests are the arrival of an HTTP request
`
`·7· ·that specifies some content that the client
`
`·8· ·is interested in transferring.
`
`·9· · · Q.· So in my example with regard to me
`
`10· ·sitting at my computer and typing in the URL
`
`11· ·that includes www.Amazon.com, would there be
`
`12· ·a request as part of that system, part of
`
`13· ·that process?
`
`14· · · A.· After you enter the URL into the
`
`15· ·browser and hit return?
`
`16· · · Q.· Enter, correct?
`
`17· · · A.· What would happen next would be that
`
`18· ·potentially one or more requests, in fact,
`
`19· ·could arrive at the server.
`
`20· · · Q.· So the one or more requests that
`
`21· ·would arrive at the server, would that then
`
`22· ·form a connection --
`
`23· · · · · · ·MR. ROWAN:· Objection.
`
`24· · · Q.· -- with the server?

`
`·2· · · A.· A connection has a separate
`
`·3· ·relationship from what we've been talking
`
`·4· ·about so far.
`
`·5· · · · · · ·A connection to a server refers to
`
`·6· ·setting up the TCP protocol to communicate
`
`·7· ·between the requester and the server, and a
`
`·8· ·connection could be used to carry one
`
`·9· ·request or many requests or no requests.
`
`10· · · Q.· So one connection to a server -- and
`
`11· ·this is not a trick question.· I'm just
`
`12· ·trying to understand.· I'm just trying to
`
`13· ·understand what you just said -- it could
`
`14· ·carry one or many requests, that one
`
`15· ·connection?
`
`16· · · A.· It could carry one or it could carry
`
`17· ·many, that's correct.
`
`18· · · Q.· With that one connection that you
`
`19· ·have?
`
`20· · · A.· With one connection.
`
`21· · · Q.· Okay.· In my example -- give me an
`
`22· ·example of how it would be more than one
`
`23· ·request?· If I've typed in the URL
`
`24· ·www.Amazon.com, hit enter, how would that be
`
`25· ·more than one request?

`
`·2· · · A.· As I said, a lot of things can happen.
`
`·3· ·It's a complicated process, right?
`
`·4· · · · · · ·If the page that is returned from
`
`·5· ·the server contains further embedded
`
`·6· ·content, the result, in some circumstances,
`
`·7· ·would be that further requests could be made
`
`·8· ·to the server.
`
`·9· · · Q.· For the embedded content?
`
`10· · · A.· The entire page consists of content
`
`11· ·that needs to be potentially obtained over
`
`12· ·multiple requests, in some cases.
`
`13· · · Q.· So if you -- let's go further into
`
`14· ·Devanneaux or Exhibit 1004.· In
`
`15· ·Paragraph 21, if you will read Paragraph 21
`
`16· ·to yourself.
`
`17· · · A.· (Witness reviews document.)
`
`18· · · · · · ·Okay.
`
`19· · · Q.· Okay.· So I'm going to direct you
`
`20· ·again to this discussion of "customer
`
`21· ·specific, customer domain specific."· Do you
`
`22· ·see that in the second sentence?
`
`23· · · A.· Yes.
`

`
`25· ·previously in the abstract, does that also

`
`·4· · · A.· Yes.
`
`·5· · · Q.· And further down on this, it appears
`
`·6· ·to give an example, and do you see where it
`
`·7· ·says, "Thus, for example, when an edge
`
`·8· ·server management process receives a request
`
`·9· ·for content, it searches an index file for a
`
`10· ·match on a customer host name associated
`
`11· ·with the request.· If there was no match,
`
`12· ·the edge server process rejects the request.
`
`13· ·If there is a match, the edge server process
`
`14· ·loads metadata from the configuration file
`
`15· ·to determine how it will handle the
`
`16· ·request."
`
`17· · · · · · ·Do you see that?
`
`18· · · A.· Yes.
`
`19· · · Q.· Do you agree with that?
`
`20· · · A.· Do I agree that that's what it says?
`
`21· · · Q.· No.· Do you agree that that is how it
`

`
`·2· ·management process receives a request for
`
`·3· ·content, it searches the index file for a
`
`·4· ·match, and I agree with the rest.
`
`·5· · · Q.· Okay.· So it says it searches an
`
`·6· ·index file for match on a customer host
`
`·7· ·name -- do you see that -- associated with
`
`·8· ·the request.· In my example, www.Amazon.com,
`
`·9· ·is that a host name?
`
`10· · · A.· As I say, the example that you gave is
`
`11· ·hiding a lot of details.· There may be
`
`12· ·different host names.· There may be
`
`13· ·different -- the host name that is put in
`
`14· ·the request may be slightly different from
`
`15· ·Amazon.com or the host name may be
`
`16· ·completely different from Amazon.com.
`
`17· ·There's a lot of possibilities in that
`
`18· ·situation.
`
`19· · · Q.· Okay.· So my example, when I type in
`
`20· ·www.Amazon.com and hit enter, and this
`
`21· ·example, it talks about a customer host
`
`22· ·name, would it be searching on something
`

`
`·2· ·It's just an example.
`
`·3· · · Q.· Now that you have given me that.
`
`·4· ·Let's go back to my question and maybe you
`
`·5· ·can answer my question.
`
`·6· · · · · · · · (The record was read: Q. If you
`
`·7· · · · · · · · had multiple requests within
`
`·8· · · · · · · · that connection, within that
`
`·9· · · · · · · · same connection of
`
`10· · · · · · · · www.Amazon.com, would each
`
`11· · · · · · · · request be searching for a
`
`12· · · · · · · · customer host name associated
`
`13· · · · · · · · with the request?)
`
`14· · · Q.· Within Paragraph 21 of the example
`
`15· ·that's given in Devanneaux.
`
`16· · · · · · ·MR. ROWAN:· Objection to form.
`
`17· ·Incomplete hypothetical.
`
`18· · · A.· There's not enough information in
`
`19· ·Paragraph 21.
`
`20· · · · · · ·To answer your question, you need
`
`21· ·to understand how the Devanneaux system
`
`22· ·works, and it's the case that the Devanneaux
`
`23· ·system might analyze only the first request
`
`24· ·on the connection, or it might analyze all
`
`25· ·the requests in the connection.

`
`·2· · · Q.· So in Paragraph 21, the sentence that
`
`·3· ·begins, "Thus, for example, when an edge
`
`·4· ·server management process receives a request
`
`·5· ·for content, it searches an index file for a
`
`·6· ·match and a customer host name associated
`
`·7· ·with the request.· If there is no match, the
`
`·8· ·edge server process rejects the request.· If
`
`·9· ·there is a match, the edge server process
`
`10· ·loads metadata from the configuration file
`
`11· ·to determine how it will handle the
`
`12· ·request."· And then you can read on the rest
`
`13· ·of that example.
`
`14· · · · · · ·Now I'm going to ask my question
`
`15· ·again and see if you agree with my question
`
`16· ·in this example that's in Paragraph 21.
`
`17· · · · · · · · (The record was read: Q. If you
`
`18· · · · · · · · had multiple requests within
`
`19· · · · · · · · that connection, within that
`
`20· · · · · · · · same connection of
`
`21· · · · · · · · www.Amazon.com, would each
`
`22· · · · · · · · request be searching for a
`
`23· · · · · · · · customer host name associated

`
`·2· ·Incomplete hypothetical.
`
`·3· · · A.· As I say, this paragraph doesn't
`
`·4· ·provide enough information to answer whether
`
`·5· ·every request in the connection would result
`
`·6· ·in a search.
`
`·7· · · · · · ·The only way to answer your
`
`·8· ·question is to look at the Devanneaux system
`
`·9· ·as a whole.· There's nothing in this
`
`10· ·paragraph that makes a hundred percent clear
`
`11· ·whether every request in the connection is
`
`12· ·analyzed or just the first.
`
`13· · · Q.· You're misunderstanding my question.
`
`14· ·What you're saying is subsequent requests,
`
`15· ·there may be no analysis done on that
`
`16· ·request?· Is that your concern about the
`
`17· ·Devanneaux system?
`
`18· · · · · · ·MR. ROWAN:· Objection to form.
`
`19· · · A.· What do you mean by "analysis"?
`
`20· · · Q.· So I'm just going back to this
`
`21· ·paragraph, Paragraph 21, where it says,
`
`22· ·we've been repeating it, "It searches an
`
`23· ·index file for a match on a customer host
`
`24· ·name associated with the request.· If there
`
`25· ·was no match, the edge server process

`
