The 7450 ESS-7 chassis supports five IOMs. Only the 7450 ESS-7 chassis uses this removable module. processed. An IOM contains two 10Gb/s traffic-processing flexible fast path complexes. The IOM processes packets received from an MDA and sends cells to the switch fabric.0 Alcatel University 7450 ESS Input/Output Module Input/Output Modules (IOM) are hot-swappable modules responsible for connecting to standard physical interfaces. Section 1 Module 4 IOM/MDA Page 4 . Similarly. Each complex supports a pluggable media dependent adapter (MDA) that allows a common flexible fast path to support all of the possible interface types.Alcatel 7450 ESS Implementation R2. An IOM also contains a CPU section for managing the forwarding hardware in each flexible fast path as well as for participating in the distributed control plane used in the system. and re-assembled into packets before being sent out an MDA interface. Each flexible fast path connects into the core switch fabric. cells are received from the switch fabric.

Alcatel Small Form-factor Pluggable Interfaces Small Form-factor Pluggable (SFP) transceivers are small optical modules available in a variety of formats.Alcatel 7450 ESS Implementation R2. Features: • Cost Effective – single module can be added or replaced instead of an entire board • Hot-swappable • Only the required SFPs need to be installed • Mix and match different types on a single MDA • SFPs are customer replaceable • Large choice of optical media Section 1 Module 4 IOM/MDA Page 6 .0 Alcatel University SFPs Alcatel strongly recommends the use of SFPs that are tested and verified by Alcatel. 7450 ESS Family – IOM and MDAs All rights reserved © 2004.

A Network Processor (NP) can decide that any arbitrary frame be copied or redirected to the local processor. In general. Each MDA provides one or more physical interfaces. from/to MDA interface). MDAs pass incoming packets to the Flexible Fast Path Complex for processing.Alcatel 7450 ESS Implementation R2. but can receive or send data from any source (either 10Gb/s complex.

The appropriate NP processes frames sent by the local processor before sending them to an MDA. this mechanism is used within the system to forward control information from card to card between the local processors.0 Alcatel University 7450 ESS Input/Output Module Components Media Dependent Adapters (MDA) Each Input/Output Module (IOM) can hold two hot-swappable MDAs. redundant. On egress the MDA processes the packets coming from the Flexible Fast Path Complex and transmits them out the appropriate physical interface in the correct format.

Local Processor Each IOM includes a general-purpose processor that is part of the 7450 ESS distributed control plane. Fabric Access (FA) The Switch Fabric consists of three major components: 1. from/to fabric. which are part of each IOM. connect the Flexible Path Complex to the switch fabric(s). 2. Fabric redundancy is designed so that the failure of a serial link or a switching element may result in system performance degradation but not total system failure. These serial links travel across the chassis backplane to connect to the switching elements of the fabric. This processor is not part of the packet-forwarding path. The fabric is used to switch this traffic in order to avoid supporting another fault-tolerant.

Each scheduler can span not only services but also virtual ports on a MDA and even virtual ports on an IOM. The 7450 ESS has a sophisticated hierarchical scheduling capability using Committed Information Rate (CIR). are passed to the network processor (NP) with a high priority. and applies the appropriate QoS policies to the packet. Once the ingress TM schedules a packet it is forwarded to the Fabric Access module where it is segmented into cells and sent to the switch fabric. The ingress TM uses a total of 8k buffers. On egress the complex supports ACLs.0 Alcatel University 7750 SR Input/Output Module Components 10 Gb/s Flexible Fast Path Complex The flexible fast path complex is comprised of the following main components: • Traffic Manager – one for ingress traffic and one for egress traffic. The egress TM. • Ingress and egress buffers. mirroring. The ingress NPs determine if the packet should be forwarded. signaling. Access Control Lists (ACLs). After a packet has been processed by the ingress NPs it returns to the ingress TM. QoS processing. consisting of 256Mb of memory. such as protocols. selects the correct egress IOM/MDA/interface. the data is passed from the TM to the NPs. (L2 & L3) forwarding logic. The hierarchical component is provided by allowing three levels of schedulers. mirroring and accounting. like the ingress TM. Once a sufficient amount of data has been received to make forwarding and QoS decisions. The ingress TM can now begin its main function of scheduling packets according to the QoS policies that have been configured for this ingress virtual interface. The Switch Fabric switches these cells to the destination IOM and its Flexible Fast Path Complex where the cells are reassembled and read into the buffers of the egress TM.

the Flexible Path Complex takes advantage of this NP stacking feature. or any other arbitrary search index.Alcatel 7450 ESS Implementation R2. Network Processor Each NP performs line-rate classification. and filter processing.g. Each NP also supports external Double Data Rate Static RAM (DDR SRAM) for storing search trees. etc. Adding filters for either traffic classification or traditional ACL purposes does not affect performance.

Alcatel The egress TM applies the QoS policies configured for the egress virtual interface to the packets and schedules the packets in accordance with the policies to the egress interface.
