Link Services PIC

The Link Services PIC provides simultaneous support for three separate capabilities: enhanced Multilink bundling, tunneling, and link fragmentation and interleaving (LFI). Supported by the M5M7i, M10i, M20, and M40e and M320 routers, the Link Services PIC can be combined with other IP Services PICs to enhance platform functionality.

  • Enhanced multilink capabilities offered by the Link Services PIC include support for FRF.16 and FRF.15 , which facilitates the efficient and cost-effective aggregation and bundling of Frame Relay links. All other capabilities offered by the existing Multilink Services PIC are supported, including FRF.15 and Multilink PPP (MLPPP). MLPPP is also supported, providing PPP over multiple discrete links such as N x T1/E1.
  • Link fragmentation and interleaving (LFI) is designed to optimize converged environments; LFI improves quality of service (QoS) on lower-speed links to ensure a high-quality user experience. An essential feature for service providers offering latency-sensitive services over low-speed links, LFI minimizes delay and jitter that are characteristic of high-payload packets. By breaking up large datagrams resulting from file transfers and interleaving low-latency traffic with the resulting smaller packets, serialization delay is minimized so overall service levels can be significantly improved.
  • The increased capability for granular traffic prioritization enables service providers to offer support for high-revenue delay-sensitive services, such as VoIP and VoD. Service level agreements can be established and stringently policed by utilizing LFI in conjunction with the Channelized IQ-PICs, which are currently offered at E-1, DS3, and OC-12 bandwidths. By policing SLAs across the network, customers are assured of a high-quality end user experience.
  • Tunneling capabilities provided by the Link Services PIC are identical to the services supported by the existing Tunnel Services PIC.
Link Services PIC Features Benefits
  • Delivers multiple edge capabilities, including Multilink, LFI, and Tunneling
  • Multilink bundling (FRF.15, FRF.16, and MLPPP) support for up to 128 bundles allows the aggregation of T1 or E1 links
  • Link fragmentation and interleaving (LFI) supported, with up to 256 links
  • Tunneling functionality is consistent with the existing Tunnel Services PIC, including IP-IP and GRE tunneling, PIM-SM, and RFC 2547bis VPN support with egress filtering
  • Reduces the number of slots needed to support multiple value-added services, increasing the total number of ports available for customer access
  • Enables customers to add bandwidth in n x T1/E1 increments, creating an affordable alternative to DS3 service
  • Reduces delay and jitter on slower-speed links by breaking up large datagrams and interleaving delay-sensitive packets with the resulting smaller packets
  • Delivers IP VPN and tunneling features to multilinked and LFI-enabled customers
