The Information distribution (I)

• Existing model Unicast distribution
• Advantages
• File reception is ensure, since it is a
  bi-directional process, connection oriented.
• Open and integrated solutions (e. g., FTP).
• Inconveniences
• Every distribution to each remote node consumes
  a determined bandwidth, in such a way that the
  available bandwidth is allocated among the number
  of simultaneous distributions.
• Delivery time is proportional to the number of
  nodes.

The Information distribution (II)

• Existing model Multicast distribution
• Advantages
• It is possible to distribute a file to n
  remote nodes using the same time and bandwidth
  than the needed for a single node in a unicast
  distribution (FTP).
• Inconveniences
• File reception is not ensure, since this is an
  unidirectional process not connection oriented.
  The only way to assure the reception is by
  retransmitting the file (data carrousel).
• Closed and hardly integrable solutions.

MultiFTP System (III)

• Multicast transmission
• - MultiFTP server uses multicast method for file
  transmission. This means that the information is
  send only once to all the clients, instead of one
  per client. This allows savings in bandwidth as
  well as in transmission time.
• Delivery guarantee
• MultiFTP client uses a return channel to confirm
  to the server the correct file reception. In case
  a client has not received the file correctly, it
  notifies to the server the lost packages of that
  file, in such a way that the server resends to
  that client ONLY the lost data, without necessity
  of carrying out a complete retransfer of the
  file.
• Costs saving
• In a distribution, at the request of the
  MultiFTP server, the receiver is connected to the
  server at the beginning and at the end of the
  transmission through any IP network (Internet,
  VPN, etc.). This type of system allows to save
  costs when dial up connections (such as PSTN or
  ISDN) are used to connect the client to the
  server. The server will not sense network
  congestion and will always transmit using the
  same bandwidth.

MultiFTP System (IV)

• Multiple Network Topologies
• - MultiFTP adapts itself to any network topology
  (LAN, WAN), but it is specifically designed for
  IP networks with an existing broadcast channel
  (satellite, LMDS, cable).
• The MultiFTP client's return channel can be any
  (dial up or dedicated) that can communicate with
  the MultiFTP server through an IP network
  (Internet, VPN).
• Multiple Service Topologies
• The information can be send directly from a
  server to the clients or using a series of
  intermediate servers as a chain, distributing
  the data firstly to those servers and finally
  from these to the clients.
• Due to its flexibility MultiFTP adapts to any
  desired topology, according to the transmission
  needs central node, regional nodes and clients.
  Each one of the nodes would transmit the files to
  those clients defined within their coverage.

Functionalities Actual Version (I)

• Centralized and secure management
• MultiFTP is based in centralized, open and
  secure management system
• Data Base Organized
• Everything MultiFTP topology, tasks,
  statistics, etc.- is organized in a single
  relational and completely open data base, making
  easier its integration with third systems
  (billing, SLA, etc.). This data base resides in
  the service central MultiFTP server
• Security
• MultiFTP establishes different platform
  management capacities. Likewise, verifies that
  the user trying to send a file has the rights
  granted to access the file in the server as well
  as in the clients computer. MultiFTP security is
  integrated in NT/2000 security. In order to avoid
  security problems the passwords are never send to
  the network. Instead a mechanism similar to NTs
  challenge/response is used.
• Remote Management
• - MultiFTP servers and clients can be manage from
  any computer connected through a TCP/IP network.
  The connected user must have the access rights to
  perform each action.

12
Functionalities Actual Version (II)

• File transmission management by means of tasks
• MultiFTP organizes file transmission by means of
  distribution tasks. There are different types of
  tasks
• Schedule task
• - A task that can be schedule to be accomplished
  in a determined moment.
• Periodic task
• A task can be schedule to be accomplished every
  certain time.
• Automatic task (folder synchronization)
• A task to send all the files from a specific
  folder, either with a schedule or periodic
  execution. Thereby the user will only have to
  copy the files into that folder and they will be
  transmitted to the clients according to the
  schedule.
• Task in star
• The information can be send directly to all the
  clients from a single server or from a server to
  several servers and/or clients. When the clients
  servers receive the files they could, at once,
  distribute them among their own clients,
  performing that way a star distribution. MultiFTP
  uses this feature to take advantage of networks
  topology.

Functionalities Actual Version (III)

• Service management
• MultiFTP facilitates powerful management tools to
  ease and ensure a quality service.
• Bandwidth management
• - A maximum bandwidth can be specify in each
  MultiFTP server. The computer will share the
  bandwidth between all the tasks, thus there will
  never be sent more information than the network
  can accept. Additionally, for each task it is
  possible to allocate an extra (BURST) and
  guaranteed (CIR) bandwidth.
• Process launching
• Each task transmission can be assigned to a
  process list to be launch, either sequential or
  simultaneously once the files are already at the
  client. The processes are launched using the user
  corresponding account and the results are
  registered in the central data base.
• Results analyzer
• MultiFPTs results analyzer would be constantly
  controlling the data base in order to help the
  user to find bottlenecks, mistakes in the
  transmission tasks, reports of use, etc.
• Clients list
• - MultiFTP administrator can define clients
  lists according to the service transmission needs
  and to the own tasks definition.

14
Functionalities Actual Version (IV)

• Ease of integration in the network
• MultiFTP has been designed in such a way that
  facilitates the manager all tasks related with
  the integration of the system in the IP network.
  
• IP Multicast group addresses management
• MultiFTP servers have guaranteed a group of IP
  multicast addresses to be used in their
  transmissions. A special dynamic link library can
  be supply so that the server could communicate to
  all external devices, to control the use of a
  specific IP multicast address and the broadband
  used. Thereby, the broadband could be
  automatically provisioned in the external
  devices, such as IP encapsulators.
• Independent access and broadband channels
• MultiFTP can use different downstream broadband
  channels in diffusion. MultiFTP client can
  connect unattended by dial-up, without user
  intervention, to any type of IP network that can
  connect him with the server PSTN, ISDN,
  Frame-relay or even Internet.
• Network services provision support
• MultiFTP server provide a middleware that allows
  a dynamic provision of multicast circuits and
  bandwidth for the distribution tasks, available
  for a large number of devices such as IP-DVB
  encapsulators.

15
Functionalities Actual Version (V)

• Friendly and intuitive interfaces
• MultiFTP incorporates different interfaces that
  help and facilitates the management task and the
  access to the services offered by this platform.
• Management Interface integrated with Microsoft
  Management Console
• - MultiFTP Management Interface is composed by
  several MMC Snap-Ins. This way administrators
  with Windows NT and/or 2000 knowledge will get
  familiar with it from the very beginning. It
  also allows an easy extensibility and integration
  with third party management applications.
• Powerful assistants
• MultiFTP management console incorporates
  powerful assistants that facilitates the task
  definition, remote connection to MultiFTP servers
  and/or clients, results extraction, etc.
• User Web interface
• MultiFTP incorporates a user web interface
  compatible with navigators such as Netscapes
  Communicator or Microsoft Internet Explorer. This
  interface is easily installable and customisable
  and incorporates functionalities such as task
  provision and management, file upload and
  transmission results report.
