The extensible Cisco I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), enabling service prioritization for data, voice, and video services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership.
Key Points
  • Per-virtual-circuit and per-virtual-path traffic shaping
  • IP QoS and Layer 3 QoS features
  • IP/MPLS-to-ATM QoS mapping
  • Any Transport over MPLS (AToM)
  • Link fragmentation and interleaving (LFI)
Product Features
  • Per-virtual-circuit and per-virtual-path traffic shaping
    Traffic shaping is a function typically provided on ATM edge devices to ensure that bursty traffic conforms to a predetermined "contract". To implement traffic shaping, the Cisco ATM SPAs support per-virtual-circuit and per-virtual-path shaping, including industry-leading minimum 1-kbps granularity, allowing flexibility and control over every virtual circuit and virtual path configured.
  • IP QoS and Layer 3 QoS features
    The Cisco SIPs and ATM SPAs support per-virtual-circuit IP QoS features that allow you to apply advanced-queuing and bandwidth-management functions, including Low Latency Queuing (LLQ), to individual virtual circuits to avoid congestion and delay. In addition, extended ACLs and committed access rate (CAR) are supported on a per-virtual-circuit basis on both ingress and egress.
  • IP/MPLS-to-ATM QoS mapping
    Also supported is IP-to-ATM QoS setting through cell-loss priority (CLP) bit support and virtual circuit bundling, which allows you to divide traffic on different virtual circuits, depending on the desired CoS.
  • Any Transport over MPLS (AToM)
    MPLS is the primary technology for ATM/IP convergence, and all the Cisco ATM SPAs allow the transport of Layer 2 traffic across an MPLS network. AToM allows a migration path toward the consolidation of IP and ATM networks while protecting existing equipment investment, and it accommodates the scaling of existing services using MPLS. All ATM operation, administration, and maintenance (OAM) functions are transported.
  • Link fragmentation and interleaving (LFI)
    LFI uses the built-in fragmentation capabilities of Multilink Point-to-Point Protocol (MLPPP) to reduce delay and jitter (variations in delay) caused by variable-sized large packets being queued in between relatively small packets. With LFI, packets larger than a configured fragment size are fragmented and encapsulated in an MLPPP header.
