  that has its own set of UCLP services.
• A Resource Object (RO) is an abstraction of the
  different physical resources that can be used
  depending on the switch hardware and technology.

• GSAP stands for Grid Services Access Point.
• Provides two grid services (UserFunctionService
  and AdminFunctionService) and their factory
  services that allow grid users to access the UCLP
  system.
• Factory services are responsible for checking the
  users identity and creating service instances
  for authenticated users.
• Once authenticated, the GSAP passes the service
  request to the Jini Service Access Point (JSAP).

• JSAP stands for Jini Services Access Point.
• Jini service that acts as the access point to the
  other Jini services within the UCLP System.
• Manages the user information database.
• Performs the lightpath discovery routines to
  discover the available LPOs needed to set up
  end-to-end connections via the Optical Routing
  Service.
• Depending on the request from the user, the JSAP
  will make service calls to the LPOS and to the
  SCS to complete the request.

• LPOS stands for LightPath Object Services.
• Responsible for managing end-to-end connections
  and lightpath objects.
• End-to-End Connection objects (E2Econnetion) and
  LightPath Objects (LPO) are stored in a JavaSpace
  corresponding to the details of each object.
• All Connections and LPOs are assigned finite
  leases that are managed by the UCLPLeaseManager
  (part of the LPOS).
• The LPOS communicates with one or more SCS(s) to
  setup connections and provision resources on the
  switch(es).

• SCS stands for Switch Communication Services.
• Communicates with and controls a switch or AS
  cloud. The specific details about the underlying
  switch or cloud remain transparent to the upper
  Jini services that call the SCS.
• Has a hierarchy of objects (ROs) that represent
  different types of resources on the switch.
• Has a hierarchy of switch information objects
  that are used to query about the current state of
  a switch.
• Waits for alarms at the switch, and notifies the
  upper layers.
• In order to handle partial failures, the SCS
  implements transactions.

• JS stands for JavaSpace.
• A JavaSpace is a persistent distributed object
  store for Java objects. Objects can be read,
  written and taken from a JavaSpace.
• JavaSpaces are transactionally secure.
• The JavaSpace implementation that is being used
  for the UCLP system is called outrigger and is
  provided in Suns reference implementation of
  Jini.

Software architecture Transaction Manager
Txn Manager

• Txn Manager stands for Transaction Manager.
• Manages and maintains transactions in the UCLP
  system.
• The Transaction Manager uses a two-phase commit
  approach.
• The Transaction Manager that is being used for
  the UCLP system is called mahalo and is
  provided in Suns reference implementation of
  Jini.

• JLS stands for Jini Lookup Service.
• Distributed Jini service registry. Each UCLP Jini
  services must register with the JLS in the same
  federation to advertise the existence of the
  service.
• The client does not have to know the exact
  location of the service it is looking for, this
  information is hidden inside the service proxy
  that is registered with the JLS.
• The Jini Lookup Service that is being used for
  the UCLP system is called reggie and is
  provided in Suns reference implementation of
  Jini.

20
Software architecture Federation Manager
Fed. Manager

• Federations use their local JLS to communicate
  with each other.
• Each JLS discovers the location of the other JLSs
  through a discovery process orchestrated by a (or
  a group of) master JLS, called the Federation
  Manager.

• Using the current implementation of

57
Transparent LAN Services (TLS) on UCLP 1.4 (II)

• The main drawbacks of the current implementation
  are
• A VLAN ID must be agreed between edges.
• Trunking is not currently supported.
• No QoS or traffic shaping is done, the bandwidth
  of the LightPath is guaranteed using an entire
  interface for each VLAN.

58
Managing Ethernet over MPLS with UCLP
Step 1- abstract the MPLS Backbone as a switch.
Step 2- assign an SCS to each switch.

• Step 3- abstract ports and slots as resource
  objects.

Step 4- abstract fibres strands as LightPath
Objects.
