Main goal: To adapt UCLPv1.5 system to HEAnet's networks.
•
Create a UCLP release compatible with HEAnet’s network elements and
architecture
•
HEAnet uses MPLS in its core network. This project will adapt UCLP to
Manage Ethernet over MPLS connections.

UCLP-HEAnet
Introduction
•
This project attempts to allow HEAnet network users to manage its
own connections.
•
Provide software to establish and control 2 connection types:
– ERS (Ethernet Relay Service) MPLS connection in VLAN mode using
subinterfaces
– EWS (Ethernet Wire Service) MPLS connection PORT mode with Q-in-Q
encapsulation
•
The software will provide a web-based GUI to establish, manage and
query these types of connections controlled directly by the user.

UCLP-HEAnet
Introduction
•
Cisco E-DI (Enhanced Device Interface) will be integrated in UCLP in
order to manage network devices with an E-DI Server.
•
The objectives will be achieved through 2 deliverables:
– the first one will implement ULCPv1.5 with a new GUI over HEAnet.
– the second one will integrate UCLPv1.5 and E-DI and its implementation
over HEAnet network.
•
As a result of this work HEAnet will test this new UCLPv1
implementation, compare it with its current provisioning software and
evaluate the possibility of deploying UCLP on its network.

What’s UCLP?
What’s UCLP?
• UCLP stands for User Controlled Lightpath Provisioning.
• As Bill St. Arnaud (senior director of Research Networks,
CANARIE) says:
'UCLP can be very simply though of as a configuration and partition
manager that exposes each lightpath in a physical network and each
network element associated with a lightpath as an 'object' or 'service' that
can be put under the control of different network users to create their own
IP network topologies'.
• This way several network operators can make part of their
resources available to end users so that they can decide when
they want to create/delete end to end connections or change the
network topology (that's why the system is called User
Controled Lighpath Provisioning).
10
What’s UCLP?
UCLP Objectives
•
UCLP was born to satisfy the requirements of certain number of applications that cannot be
implemented using centralized network management tools. Some of this applications are:
•
Customer controlled and managed networks.
Universities, regional networks and large enterprises/institutions acquire their dark fiber/lambdas
and they light them.
These organizations want to manager the new resources with the ones they own in a transparent
way and under a single management domain.
Each institution must be able to implement its own topology discover or protection mechanisms.
•
Dedicated IP networks. Aplications and disciplines with high bandwidth requeriment:
Current IP networks are optimized for thousands of clients with relatively small traffic flows
All over the world are emerging small comunities who need to interchange high amounts of traffic
at a high bit rate (grid applications, e-science, sensor and instrument networks).
•
User controlled traffic engineering:
Allow local and/or regional network managers to apply their own traffic engineering policies.
Using UCLP they can create new BGP paths between two networks creating a direct optical
connection.
Big companies and regional networks can be interconnected directly using a peering point instead
of a hierarchical IP network.
11
What’s UCLP?
Definitions
• A LightPath Object (LPO) is an abstraction of one or more
lightpaths (represents a connection between two
consecutive nodes).
• A Resource Object (RO) is an abstraction of a network
interface (Ethernet, SONET/SDH, wavelength WDM).
• An End-to-End Connection Object (E2ECO) is
abstraction of an e2e connection in the UCLP system.

Services types
• The two key layer 2 Ethernet Virtual Circuit (EVC) services
that HEAnet shall provide are:
• Ethernet Wire Service (EWS) is a point-to-point port-based
transparent EVC that is used primarily to connect
geographically remote LANs over the HEAnet network.

HEAnet’s UCLP
Services types
• Ethernet Relay Service (ERS) is a point-to-point VLANbased EVC. It is presented to the user as an 802.1q trunk
which filters customer Layer 2 control protocols and uses
the different customer VLAN IDs to direct customer traffic
to different destinations. ERS is a non-transparent service,
which means that the customer Layer 2 control protocols
are dropped.

HEAnet’s UCLP
Resource partitioning
•
In order to offer ERS/EWS services, network resources have to be
partitioned accordingly to the needs of each connection, since several
connections can use the same port or link.
•
This implies that “parent” ResourceObjects and LightPathObjects
have to be partitioned in several sub-resources, one for each
connection that uses them.
•
Manually-generated ROs and LPOs are called “parents”, and do not
participate in any connection, only have information about the physical
resource and the remaining capacity in that resource.
•
Each time a connection is requested, parent resources partition
themselves to generate sub-resources with enough capacity for the
connection. After that the parent resources updates its current
available bandwidth.

Supported devices
• UCLP’s adaptation for HEAnet supports the following devices:
– Cisco 7600 routers (created from scratch)
– Cisco Catalyst 3750 switches (modification of an existent package,
keeping full compatibility)
• Moreover, a new pseudo device has been implemented to
support connections across MPLS networks (MPLSCloud). This
pseudo device contains instances of the edge devices of the
cloud
• In addition to the MPLSCloud, a new type of resource object
has been defined (MPLSRO). This kind of resource object
represents edge interfaces of an MPLSCloud
• New devices can be added simply by adding a Java package to
the SCS layer

E-DI
•
E-DI stands for Enhanced Device Interface
•
Cisco E-DI provides a comprehensive management interface for Cisco
devices and offers interfaces for two categories of users:
– the human user interacting with network
devices through CLI
– management application programs interacting
with network devices through an XML
programmatic interface.
•
Cisco E-DI provides a CLI user interface (CLI-UI) and
an XML programmatic interface (XML PI). Cisco E-DI
can be deployed in conjunction with a management
application, or in a stand-alone configuration.
•
E-DI has been integrated in ULCP in order to give
the possibility to manage equipment with the E-DI
XML PI.
