3. Key Challenges for 2013
• Keep up with the tests for all the test-beds
o BNG Test Bed
o Core & Staging Test Bed
o Metro Ethernet Test Bed
o NG-SDH Test Bed
• Become Test Bed for DT Group (BNG)
• Expand participation in R&D Projects
• Support OTE’s Business Customers (proof of concept tests, for presales)
• Expand the capabilities of the Spirent Test Center to keep up with the network demands
Core Lab main Testbeds
• Metro Ethernet Testbeds– Point-to-Point (E-line), Point-to-MultiPoint (E-Lan), Multipoint-to-Multipoint
(E-Tree)– Spanning Tree, LACP
• L2 & L3 Vpn Services• QoS• PPPoE Testebeds
– Session Termination for Static and Dynamic Users– Authentication based on different parameters (circuit-remote id)– Subscriber attachment to VRF– L2TP / LAC operation– Qos applied to Subscribers
• IPTV– Multicast video distribution with MVPN (PIM SSM)
• IPv6– IPv6 subscriber termination (PPPoE) with Prefix Delegation– Dual Stack (for PPPoE sessions)– 6VPE
