1. E1-E2 CFA Module PAN TECHNOLOGY OVERVIEW For internal circulation of BSNL only

2. LEARNING OBJECTIVES For internal circulation of BSNL only PAN overview PAN switches and OCPAN

3. WHAT IS PAN For internal circulation of BSNL only Packet Aggregation Network (PAN) is designed to work between access and the core network. PAN switches aggregate voice, video, and data (Any type of traffic STM1, Ethernet, IP, ATM) from the access network and hands it over to the core (IP-MPLS/OTN). PAN equipment works in ring topology to provide protection to the traffic.

4. AGGREGATION NETWORK DEPLOYED PRIOR TO PAN SWITCHES BSNL has deployed a RPR technology based Aggregation Network for aggregating the Metro IP Traffic BSNL has also deployed a LAN Switch Based Aggregation Network for aggregating the traffic from the other small cities (OCLAN switches )

5. Architecture of Multiplay network prior to PAN For internal circulation of BSNL only

6. FUNCTIONAL REQUIREMENTS OF PAN SWITCH For internal circulation of BSNL only PAN switches in the aggregation domain are expected to collect the customer traffic from access network elements like DSLAM, MSAN or FTTH and hand over to the IP-MPLS core network. MNG-PAN shall have functionality like ability to create Ethernet Layer 2 VPN such as point to point, point to multipoint as well as multipoint to multipoint to isolate the customer traffic into their own logical virtual network. Switching fabric plane of PAN switch shall be bidirectional and non-blocking. MNG-PAN switches shall support built in power diagnostics to monitor optical SFP/XFP ports and system diagnostics for hardware failures

7. For internal circulation of BSNL only PAN switch c hassis shall have high availability and redundancy features, rack mountable and support easy expansion through addition of tributary cards within the same chassis (Carrier class equipment) Aggregation switch should be designed in such a way that there is no single point of failure. For this, the architecture shall provide 'packet switching fabric‘ redundancy. Resiliency of the equipment shall be sub 50msec recovery in Ethernet rings for aggregation layer. Equipment shall interface to the existing BNG and nationwide MPLS core network wherever required. FUNCTIONAL REQUIREMENTS OF PAN SWITCH

8. FUNCTIONAL REQUIREMENTS OF PAN SWITCH For internal circulation of BSNL only MNG-PAN switches shall support point to point, point to multipoint and multipoint to multipoint traffic in full duplex mode of working. MNG-PAN switches shall be able to function in terminal mode, hub/star, mesh, and ring topology MNG-PAN switches shall provide managed multi-service integration viz voice, video, and data

9. DEPLOYMENT ARCHITECTURE OF PAN SWITCHES For internal circulation of BSNL only

10. Types of switches in PAN For internal circulation of BSNL only PAN-COAU – “ Packet Aggregation Network – Central Office Aggregation Unit” switch. (for connecting to BNG or to MPLS routers) PAN - “ Packet Aggregation Network” switch ( for connecting OCPAN with PAN- COAU) OC-PAN – “Other City Packet Aggregation Network” switch ( for connecting CE equipments with PAN switch)

11. Features of PAN Network For internal circulation of BSNL only PAN network is based on Pseudo Wire over MPLS-TP technology that supports an efficient Ethernet aggregation. PAN platform offers wide range of protocols, standards and interfaces coupled with highest reliability . Carrier-class set of features, including the carrier class sub 50ms recovery resiliency. Hard QoS /SLA guarantees End to end and multi-layer OAM, network-wide time/clock synchronization

12. For internal circulation of BSNL only Efficient multicast data distribution . Range of interfaces up to 10GE. Low power consumption. Centralized management Features of PAN Network

13. Advantages of PAN Network For internal circulation of BSNL only Scalability : Support of electrical and optical Ethernet interfaces from FE to 10GE. Large switching capacity. Reliability : Carrier class reliability with fully redundant hardware architecture. Resilience : Various protection schemes, sub-50ms failure recovery. Manageability : Enhanced OAM capability with end-to-end service management. NMS-based operation.

14. Advantages of PAN Network For internal circulation of BSNL only Inter-operability: Compliant with ITU-T MPLS-TP standard. Easy integration with core IP/MPLS or OTN networks. Bandwidth Efficiency : Packet nature of the network with flexible data-pipes enables users to request the service in smaller increments and provides better utilization at the aggregation level. Lower TCO : Low power consumption; bandwidth efficiency due to optimized packet aggregation; fast f ault isolation and simple management
