RPR - UTStarcom NetRing 10000R

The NetRing 10000R is deployed as Tier-1 & Tier-II RPR in BSNL Multi Play Project. NetRing 10000R is a Resilient Packet Ring (RPR) transport system designed to address the requirements of data-centric networks,

dramatically reducing both operational and capital expenditures. It empowers networks with the advantages of RPR in conjunction with the

flexibility of Ethernet.One 10000R chassis can provide either two 10G RPR rings, four 2.5G RPR rings, or a combination of both. It also employs a fully distributed

design, which includes dual power inputs, dual control modules, and dual packet-processing modules. The platform converges legacy Ethernet with

emerging metro Ethernet technologies. Together with UTStarcom GEPON or DSLAM products enables end-to-end Metro Ethernet solutions

for IPTV, VoIP, and the next generation of multimedia services. It is an excellent solution designed to meet the rapidly evolving industry

requirements for 10G/GE RPR Metro Ethernet networks.

Challenges from Metro Ethernet Network

• No guaranteed bandwidth– Limited ports density of core network– Low uplink bandwidth of convergence layer– Low expansibility of BRAS, especially when supporting PPPoE– Limited access bandwidth for ATM DSLAM

• Lack of carrier-class intelligence services– Limited flow control– No carrier-class service protection < 50ms– Uncontrollable delay and jitter (especially with high throughput）– Lack of end-to-end QoS guarantee

• Low quality security– Isolation per different access users– Security deficiency of convergence layer, liable to be hacked

• others– Not supports multicast completely– Huge L2 network with limited VLAN address… …


RPR is Perfect for Metro Ethernet

• Simple and stable physical topology and logical topology– Compared with traditional mesh topology, the RPR ring based

topology greatly simplifies the physical topology, substantially reduce the fiber connections and router ports.

– From logical point of view, all nodes on a RPR ring are directly connected, thus reduces the routing table amount. In case of a link failure or a node failure, there is no need to re-calculate the routing path which has significant meaning to a large scale IP backbone.

• High quality services at low cost– Native QoS -- four types service A0/A1/B/C corresponds to ATM

CBR 、 VBR-rt 、 VBR-nrt 、 UBR– Carrier class reliability -- < 50ms fast protection switch


Protection

• RPR has the ability to protect the network from single pan failures. When a failure occurs, protection messages are quickly dispatched to all nodes in a ring.

• RPR has two protection mechanism.– Wrapping– Steering


Protection

• Wrapping:

Nodes neighboring the failed span will direct packets away from the failureby wrapping traffic around to the other fiber (ringlet). This mechanism requiresthat only two nodes participate in the protection event. Other nodes on the ring can send traffic as normal.


Steering

• Steering – The protection mechanism notifies all nodes on the ring of the failed span. Every node on the ring will adjust their topology maps to avoid this span.

• Regardless of the protection mechanism used, the ring will be protected within 50 ms.


RPR Benefits

Bidirectional transfer at full bandwidth between 2 nodes

Rest of ring span idle and available for traffic

Metsolve OSS an Overview

Components of OSS (Metasolv):a) Order Management System (OMS)b) Inventory Management (IM) OMS Order management system streamlines provisioning processes. It automates the generation and scheduling of tasks. Order Management system covers workflows & processes from the time a

subscriber is identified as a lead in the front end system (web portal) to the time the customer is active on the network.

Order Management system shall facilitate service delivery in areas including: Manual–including installing equipment in a point of presence. Automated–including triggering billing once the service is activated in the

network. Fulfillment of service orders.

IM Helps to manage all the resources required to deliver communications services Facilitates the tracking of all physical resources ranging from access mediums to

physical equipment to asset locations and addresses


• Customer request is entered into an order entry system

• Service order is created and passed to Service Activation

• Service Activation activates service on “required equipment”

Postpaid Flow

Process Step Description

STEP 1. Subscriber will be provisioned in the LDAP system.

STEP2. To connect the service, the subscriber will enter Username & Password. The request is received by the Proxy AAA from NAS/BRAS. Proxy AAA will do AA functionality locally.

STEP 3 To complete AA functionality Elite Radius will have to check the Credit Limit of the subscriber.

Step 4 If necessary Credit Limit is available, Elite Radius will get other attributes from Subscriber LDAP Profile along with the Credit Limit..

Step 5 Subscriber will successfully connect the service.

Step 6 When the subscriber disconnects the service, NAS/BRAS will send Accounting Stop request to Elite Radius and Elite Radius will generate CDRs.

Netsweeper solutions to BSNL

• Netsweeper will provide controlled internet service by forwarding the user web request to the internet policy server. The requested URL will be examined by policy server by checking the URL database and it is allowed or denied based on the policy set.

• Netsweeper will provide restricted URL database as per the requirement divided into 20 categories.

• BSNL can create or set its own policy to their users and the users using this policy cannot access the restricted category.

• The URL database can be updated simultaneously to all servers on real time.

• Access restriction is based on URL database either part or complete URL.

• Netsweeper solution is sized to support BSNL requirement of 100,000 requests per second and will not introduce delay more than 50ms per request

Hardware for Netsweeper – BSNL Solution

• Each Netsweeper Policy server will replicate the data to the other

systems via a Parent - Child replication method using MySQL.

• All servers will be managed, configured and updated from a central

location at once.

• Netsweeper will provide managed, reported and administrable internet

service by redirecting the upstream traffic to the policy server

• The proposed filtering solution is very much scalable for the future

needs.

• Policy server can handle one or more policies with different category

settings so that the user cannot access websites that fall under the

restricted category.
