    • Frame Encapsulation Protocol (FEP) is High Performance Data Packet Transport for Next-Generation SONET/SDH Systems FEP Technologies
    • Today’s Reality
      • Today’s economic realities drive service provider demands:
        • Limited Cap-Ex/Op-Ex
        • Leverage existing infrastructure
        • Standards based network upgrades and enhancements
        • Service profitability, instant revenues
      • Service demands still growing
        • Service convergence
        • Multi-protocol support (TDM & data)
        • IP bandwidth, Gigabit Ethernet
        • Dynamic bandwidth
      • Metro networks poorly positioned to meet those demands
        • SONET/SDH not optimized for Ethernet/IP
        • Crowded/Complex COs = high Op-Ex
        • Limited excess capacity (unlike the WAN)
        • No inherent QoS for toll quality VoIP
      • New vendor selection philosophy
        • Diversify but keep at least one legacy
        • Seamless, transparent plus ins required
        • Manageable with existing NMS
      Metro Edge Metro Edge Metro Core POP POP POP DXC WAN End Users Congested Networks POP
    • The Challenges Faced
      • Metro Transport Challenge
        • How to improve bandwidth utilization for Ethernet over SONET/SDH data transport services?
          • Increased demands for bandwidth services
          • Congestion on existing facilities  Effects QoS
        • Transport options:
          • IP over ATM
          • IP over PPP/HDLC
          • Gigabit Ethernet
          • Resilient Packet Ring (RPR)
      • Metro Access Challenge
        • How to expand available bandwidth without adding new telco facilities?
          • Improve bandwidth utilization of existing facilities
          • Cost of adding additional facilities  New fiber or light dark fiber
        • Access Options:
          • Dedicated facilities
          • Deploy Fiber To The Premise (FTTP)
          • Implement peering
    • SONET Labs Approach
      • Develop the BB155 Ethernet over SONET/SDH box
        • BB155 implements ITU standard Generic Framing Procedure (GFP)
        • Efficiently encapsulates Ethernet/IP data in SONET/SDH payloads
      • SONET Labs BB155 installed at the on-net point of presence
        • Most growth and pressure on metro network is from Ethernet/IP data
        • Improves efficiency of transporting Ethernet/IP traffic over SONET/SDH
        • Prolongs the life of existing SONET/SDH rings and access facilities
      • SONET Labs BB155 is a seamless network device managed by carrier or service providers existing network/element management system
      • SONET Labs BB155 developed for in-country manufacturing
        • SONET Labs will license BB155 manufacturing to carrier or service provider specified equipment manufacturer
        • Complete documentation package delivered to selected licensee
    • BB155 - Ethernet over SONET/SDH
      • RJ45 or Ethernet Fiber (E-fiber) interfaces
      • ITU-T G.7041/Y1303 compliant GFP framer/mapper
      • Standard OC-3 optical interface
      • ETSI compliant (temperature, humidity, shock, vibration)
      • FCC and CISPR-22 emissions compliant
      • Standard SNMP and MIB-II support
    • BB155 EoS - Data Stream
      • Ethernet-IP traffic efficiently transported over SONET/SDH networks
      • Uses GFP-framing with MAC extension headers
      • Upgradeable platform for future enhancements including
        • SONET/SDH routing
        • Auto-provisioning
        • QoS on SPE
        • GFP/”Alternate FEP” support in MPLS
        • CWDM
    • On-net Building Deployment
      • Improves transport efficiency of Ethernet/IP on SONET/SDH rings
      • Conserves bandwidth on metro SONET/SDH ring
      • Delays need for capital investment/upgrade of SONET/SDH ring
      • Platform for future service enhancements
      • and upgrades
    • Off-net Building Deployment
      • Conservers bandwidth between Metro core and building
      • Extends life of existing access facilities
      • Plug & play with existing CO and existing access network
      • Improved bandwidth utilization of existing fiber SONET/SDH transport networks
      • Low transport overhead
      • Low latency  SONET/SDH encapsulation implemented in hardware
      • Managed network object
        • SNMP v2 compliant
        • Standard SONET/SDH and TCP/IP MIB-II definitions
      • Lowest total cost solution
      • Performance comparisons:
        • 45% performance improvement against IP over ATM
        • 35% performance improvement against IP over PPP/HDLC
        • Based on IP over SONET/SDH testing conducted with Telecordia
      • Establish Inter-company Working Groups
        • Objectives are:
          • Refine network architecture and configuration
          • Conduct joint interoperability testing
          • Establish technical and business relationship with your infrastructure equipment providers
