Not much to see in terms of DEMO.
So, this session focuses on architecture and
best fit for your environment.

an office
exists in a branch location.
Businesses today need cost-effective solutions that don’t
necessarily require on-site hardware.
However, such solutions should be “future proof”,
e.g. scalable with hardware if needed in the future.
Solution: BranchCache!
transparently
automatically
BranchCache’s services operate “below” the
SMB/HTTP/BITS stack.
This means that any tool (Robocopy, WMP, IE, Flash, Silverlight,
etc) that uses SMB/HTTP is transparently and automatically
cached.
previously
generated content
previously
generated content
Call it…“content metadata”.
Content is broken into blocks, or “chunks of data”.
For each block, block and segment hashes are computed (using SHA-256).
Compression ratio of hash to original content is around 2000:1.
One file == many blocks. Discrete content chunking.
Its faster to compare content “chunks”
than actual content.
All of this is transparent to both you
and the user.
The previous example used a Distributed Cache
the hosted
cache server connects to the client and
downloads the content to store in its cache
Notice:
Initial access in each example is always
to the Main Office’s content server.
Thus:
No change in user behavior.
Why?
Eliminates need for multicasting
Protocol
Used For
SHA-256
Hashing data on content server.
HTTP / SMB / BITS
Initial client communication with content (file,
web, application) server.
BranchCache Discovery Protocol
Used by clients to search local network for
content.
WS-Discovery
Used by BranchCache Discovery Protocol
(Web Services, Multicast, UDP)
BranchCache Retrieval Protocol (MSPCCRD)
Used by clients to obtain content (HTTP)
BranchCache Hosted Cache Protocol (MDPCHC)
Used by clients to advertise to Hosted Cache
that they have content for storage.
