The Business Need


8/59 2012 Cisco and/or its affiliates. All rights reserved. Cisco PublicPresentation_ID 8

The Business Need

The demand for bandwidth is increasing- The drive for bandwidth intensive multimedia applications

- The need to centralize storage and servers and implement remote businessstrategies (Cloud)

- The need for flexible upgrade capabilities

- Wholesale /open networks to other providers

The demand for sophisticated services is increasing. Carriers need to staycompetitive, as customers looking for solutions that:

- Provide Collaboration & service consolidation - run Data, Voice & Video onone network with QoS

- Ensure the best performance (SLAs) for the always on connected world

- Ensure Privacy & Security, as the level of concern imposed by new servicesincreases

All of the above fast and efficiently @ a click

Bandwidth and Sophistication @ competitive prices




hellas online operates a 2500Km Metro Area fiber network for corporatecustomers with Nortel equipment. For this, the company was awardedthe MEF "Outstanding Innovation" award in 2005

In 2009 we decided to renew the equipment

The challenge was quite high as the service already provided was moreadvanced in features from the competition

hellas online Cisco ME The Project and Solution



hellas online Cisco METhe Project

Scope: 5 core nodes, >1000 CPEs, >4000 CircuitsTimeline: Over 1 year project preparation and testing

Selection Process- Discussions with most of the major vendors

- Down to two possible vendors- Over 5 months in house lab testing (POC)

Primary goal: A network architecture that supports all features required

Secondary goal: Support provisioning @ a click- Existing Operations teams not Cisco friendly

- Launch immediately, no time for extensive Cisco IOS training

- Northbound Interface to CRM and Business Assurance tools

Cisco IP Solution Centre (ISC)



ISC Provisioning Facts

Definition : Cisco IP Solution Centre is a family of intelligent networkmanagement applications for planning, provisioning, and automateddiagnostics of MPLS and Carrier Ethernet networks

Key Idea : The operator will select the end-points of a service and ISC willdeploy this service configuring every device in the path with theappropriate commands

NOTE : ISC is not an NMS, just a provisioning tool

The Challenges


22/59



Existing Metro Network infrastructure Nortel devices CLI vs.GUI- Operators accustomed to GUI provisioning

- No CLI or Cisco IOS experience

- Smooth Transition KISS principle

Mapping of marketing/sales Metro Services Offerings to ISC Policies- 3 Starter Services ISC Policies

- Basic Premium Gold

- Differentiation in CoS marking, MAC numbers, L2 tunneling

The Challenges Business


23/59



FlexUNI/EVC Policies for provisioning E-Line and E-LAN Ethernetservices over a VPLS core

- Not out of the box solution

- Integration / Customization phase

- Configuration Templates chosen by Operators or attached to Policies

Dual attached rings not supported in 5.2 (later in 6.0)- Workaround provided by second ES+ LC (pseudo links)

All configurations must be done by ISC and not by CLI- Device configs must be in sync with ISC for smooth operation

- CLI is more error prone

- CLI is not a scalable solution

The Challenges Technical


24/59



Reduction in provisioning errors- Service Design through planning

- Automatic deployment of commands to all relevant devices

Speed Time to Market

- Quick deployment of services on the network

Device Awareness- Automation of which commands to what devices

Services Assurance

- Easy to identify the services deployed for customers

E-Line Service- UNIs on SW2 and SW6

- Commands for SW1-SW2-R1-R2-R3-R4-SW5-SW6

Internet Feed Service- UNI on SW7

- Direct Connect Link on R5

- Commands for R5-R3-R4-SW7-SW8

Step by step


39/59


ISC Provisioning

1. Select a Policy- Set of predefined commands and values configured

based on design (Gold service, OAM, number of MAC addresses allowed)

2. Select End-points- Which devices participate in the service

3. Select Interfaces- Specify the UNI interfaces

4. Fill in the service attributes- Service Instance, Bridge Domain, S-Vlan, VLAN

manipulation, UNI type

5. Select additional templates- Extra commands to complete the service (QoS)

ISC ProvisioningDeployment Action

ISC will check the LOGIC for inconsistencies- Mismatched attributes, UNI encapsulation

ISC will collect all parameters of the SR and combine them with the attachedtemplates to produce configlets per device

ISC will try to download the configlets to all appropriate devices in the network

Once finished it will gather the latest configuration from devices

It will perform a configuration audit for the commands provisioned bycomparing configurations files
