UCLP-HEAnet Introduction
5
• 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).
11
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.

LightPath
Slot / Port
• 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 an abstraction of an e2e connection in the UCLP system.

• 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.

• Ethernet Relay Service (ERS) is a point-to-point VLAN-based 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.

HEAnet’s UCLP 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
21
HEAnet’s UCLP E-DI
– 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.
• 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:
