  1. 1. Frame Encapsulation Protocol (FEP) is High Performance Data Packet Transport for Next-Generation SONET/SDH Systems FEP Technologies
  2. 2. Today’s Reality <ul><li>Today’s economic realities drive service provider demands: </li></ul><ul><ul><li>Limited Cap-Ex/Op-Ex </li></ul></ul><ul><ul><li>Leverage existing infrastructure </li></ul></ul><ul><ul><li>Standards based network upgrades and enhancements </li></ul></ul><ul><ul><li>Service profitability, instant revenues </li></ul></ul><ul><li>Service demands still growing </li></ul><ul><ul><li>Service convergence </li></ul></ul><ul><ul><li>Multi-protocol support (TDM & data) </li></ul></ul><ul><ul><li>IP bandwidth, Gigabit Ethernet </li></ul></ul><ul><ul><li>Dynamic bandwidth </li></ul></ul><ul><li>Metro networks poorly positioned to meet those demands </li></ul><ul><ul><li>SONET/SDH not optimized for Ethernet/IP </li></ul></ul><ul><ul><li>Crowded/Complex COs = high Op-Ex </li></ul></ul><ul><ul><li>Limited excess capacity (unlike the WAN) </li></ul></ul><ul><ul><li>No inherent QoS for toll quality VoIP </li></ul></ul><ul><li>New vendor selection philosophy </li></ul><ul><ul><li>Diversify but keep at least one legacy </li></ul></ul><ul><ul><li>Seamless, transparent plus ins required </li></ul></ul><ul><ul><li>Manageable with existing NMS </li></ul></ul>Metro Edge Metro Edge Metro Core POP POP POP DXC WAN End Users Congested Networks POP
  3. 3. The Challenges Faced <ul><li>Metro Transport Challenge </li></ul><ul><ul><li>How to improve bandwidth utilization for Ethernet over SONET/SDH data transport services? </li></ul></ul><ul><ul><ul><li>Increased demands for bandwidth services </li></ul></ul></ul><ul><ul><ul><li>Congestion on existing facilities  Effects QoS </li></ul></ul></ul><ul><ul><li>Transport options: </li></ul></ul><ul><ul><ul><li>IP over ATM </li></ul></ul></ul><ul><ul><ul><li>IP over PPP/HDLC </li></ul></ul></ul><ul><ul><ul><li>Gigabit Ethernet </li></ul></ul></ul><ul><ul><ul><li>Resilient Packet Ring (RPR) </li></ul></ul></ul><ul><li>Metro Access Challenge </li></ul><ul><ul><li>How to expand available bandwidth without adding new telco facilities? </li></ul></ul><ul><ul><ul><li>Improve bandwidth utilization of existing facilities </li></ul></ul></ul><ul><ul><ul><li>Cost of adding additional facilities  New fiber or light dark fiber </li></ul></ul></ul><ul><ul><li>Access Options: </li></ul></ul><ul><ul><ul><li>Dedicated facilities </li></ul></ul></ul><ul><ul><ul><li>Deploy Fiber To The Premise (FTTP) </li></ul></ul></ul><ul><ul><ul><li>Implement peering </li></ul></ul></ul>
