The document discusses a novel cloud service named transparent computing, which enhances the traditional von Neumann architecture by enabling spatio-temporal data storage and program streaming. It outlines the key components of cloud computing, including infrastructure, platforms, and software services, and presents a new model where programs are hosted on central servers and streamed to client devices. This approach reduces hardware costs, enhances personalization, and simplifies maintenance by separating computing from storage.

architecture is
composed of three
distinct components (or
sub-systems): a

(CPU),

interfaces.

• The existing stored program concept the instructions
and data are treated and stored in the same way in the
storage devices.
• This traditional way of storage with local devices is hard
to provide personalized or active services to users.
• The small, limited size embedded devices cannot hold
all the needed programs.
• Programs on the local storage need maintenance,
fighting against malware, and other management jobs.

*Meta OS, to support Oses streaming through a distributed
4VP+ (4Layer 2 Protocols) platform.
*Meeting user demands for any computing services in a
trouble-free way in the right place at right time.
* The essential idea is to spatio-temporally extend the
traditional stored program concept.
*Programs are stored on the central computers
(servers) The programs are streamed computers (embedded
devices or clients).

*A fundamental paradigm shift from traditional
solutions
*Some changes from traditional system:
1. System Architecture
2. Computing Model
3. Separate computing and storage: store
program in server, execute program in client
4. Management
5. Centralization

• One computer(client) is responsible for computing .
• The programs stored on another server streamed via
the network.
• The programs will be streamed back to the client in
small streaming blocks on demand via the network,
to be executed with the local resources, such as
memory and CPU.

mostly installed in a

clients remotely .
• The V-user module is used to
manage users.
• The system has to authenticate
them through a network
authentication protocol, such as
Kerberos

20. Network service access protocol
The core idea of 4VP+ is virtual
disks.
The access of virtual disk images
on the server is through NSAP.
Functions of NSAP:
connection between the V-disk
image on the server side and the
V-disk on the client side.
Each client can maintain two
request queues
Deliver the instructions and data,
including OS codes from the
server to clients
Format of NSAP.
The NSAP uses User Datagram
Protocol (UDP) to deliver data
packages.
Each remote-disk request
has a unique ID,
 The maximum size of data
to be read or written by a
remote- disk request to 32
KB.
To avoid out of order
requests, each client uses
a simple wait-and-send
solution20

21. The core technique of 4VP+ is
the virtualization of devices and
users.
 For transparency to OSes and
users, the virtual I/O is
triggered with virtual disks.
 V-disks are flat addressable
block- based virtual storage
devices located beneath the file
systems.
A V-disk image consists of one
or more files, depending on the
required disk size.
The virtual disk access is
implemented through NSAP
* Virtualizations and management
The 4VP platform classifies
client V-disks into four
different categories to enable
sharing and isolation.
First, 4VP separates software
from data,.
21

22. * 22

23. Second, 4VP+ maintains a “golden image” of a clean system
that contains the desired OS and a common set of
applications.
This “golden image” is thus immutable and can be shared by
all clients
4VP+ adopts a COW approach by having a COW V-disk for
each client.
The file system redirector can filter the file written
operations and redirect them to the COW disk.
Thus, there are four categories of V-disks in 4VP+ :
1. System V-disk (S)
2. Shadow V-disk (H)
3. Profile V-disk (P)
4. User V-disk (U

*Client/embedded devices
require less CPU power and
memory.
* Reduces the hardware cost
*Client devices can run
different programs (including
OSes and applications).
*Reduces the software cost
*Reduce the costs of
maintenance:.
*All computing services and
technologies are transparent
to users. 25

*Select and demand their desired services.
*Moreover, the system based on 4VP+ can achieve a
lower cost than before.
