1005 Exhibit: Exhibit 1005 Francis Yallcast

Document IPR2017-01600, No. 1005-8 Exhibit - Exhibit 1005 Francis Yallcast (P.T.A.B. Jun. 16, 2017)
Viewed this way, the majority of what gets transmitted over the internet is distribution: mail, news, web pages (HTML) and files of all types (jpg, mp3, etc.), chat, channels, DNS records, audio-video broadcasts, and so on.
In addition to open standards like NNTP, IRC, ICP, RFC822 mail headers, and so on, many companies offer proprietary server-based systems: Pointcast for its channels, Tivoli for its software distribution, Tibco for its publish/subscribe stuff, RealNetworks for its audio-video broadcasts, and on and on.
In fact, a key objective of most reliable transport protocols for IP multicast is to build a tree (among routers or among hosts, depending on the scheme) over which acks or naks can be sent.
Recently the IETF chartered an ad hoc group, called maddogs, to explore ways to overcome the problems of IP multicast and to make it more suitable for commercial products and services.
All other intent to joins are stamped as rejected and replicated, with one copy going back the way it came over the reverse path to flush it from the loop detection maps, and the other going directly to the originator.

1031 Exhibit: Exhibit 1031 Ballardie Francis Core Based Trees

Document IPR2017-01600, No. 1031-34 Exhibit - Exhibit 1031 Ballardie Francis Core Based Trees (P.T.A.B. Jun. 16, 2017)
Most LANs and more recent wide-area network tech nologies such as SMDS (12) and ATM [7) specify mul ticast as part of their service, but perhaps the most apparent and widespread growth in multicast applica tions is being experienced in the IP Internet.
IP Module ,ll 11, Local Network Service Interface Figure 2: Protocol Relationships CBT operation is invoked whenever a router receives a group membership report as part of IGMP from some host on a directly attached subnetwork.
owever, a ne~~t1ve ac owledgement (JOIN-NACK) may be sent 1n reply to a Join request for various reasons, for example, in the event of loop detection, or simply because the router does not wish to become part of a CBT tree for that group.
We consider the development of a dedicated mul ticast directory service which would be responsible for all aspects of group management, a long term goal of internetwork multi casting in general.
Also, Joel Halpern (Network Systems Corpora tion), Steve Deering (Xerox Pare), and Scott Brim (Cor nell University) for their general constructive comments and suggestions since the conception of CBT.

1003 Exhibit: Exhibit 1003 Declaration of Dr Nicholas Bambo, PhD

Document IPR2017-01600, No. 1003-48 Exhibit - Exhibit 1003 Declaration of Dr Nicholas Bambo, PhD (P.T.A.B. Jun. 16, 2017)
For these reasons, and as described in greater detail below, it is my opinion that the methods recited in the subject claims were known and obvious to one of ordinary skill in the art prior to the filing of the ’069 patent.
In my opinion, a person of ordinary skill in the art seeking to improve or modify the system taught in Francis would have looked to similar concepts discussed in Gilbert for inspiration.
Additionally, a person of ordinary skill in the art seeking to further improve the system in Francis by increasing the efficiency of the join process would have also been inspired by Gilbert’s use of a network manager to identify and contact an existing member node.
A person of ordinary skill in the art would have been further inspired by the efficiencies achieved by Gilbert’s teachings of having the portal computer sending the connection request to existing nodes on the network.
A person of ordinary skill in the art seeking to advance Francis’s objective that “each member establishes the same number of mesh links” would have looked to Gilbert for inspiration on how to maintain such a topology while adding new nodes.
