The Alcatel-Lucent Service Router comes in three chassis options: the SR-1, SR-7, and SR-12.

The modular design of the 7750 provides the ability to add or remove hot-swappable cards as

required. There are two types of card slots:

SF/CPM Card SlotThe Switch Fabric (SF) and Control Processing Module (CPM) contains the switch fabric and the

control processor complex. The switch fabric consists of multiple switching elements that are

responsible for sending cells received on one port out another. The processor complex is

responsible for the overall control of the system.

IOM Card SlotI/O modules (IOM) are responsible for connecting media dependent adaptors (MDA), which provide

physical interface termination, into the system. The IOM processes received frames from an

interface to accomplish all switching decisions. It implements per service QoS functions, access

control lists (ACLs) and accounting, formats frames into cells to be switched through the core fabric,

and sends cells to the fabric. Frames to be sent out interfaces are first received from the fabric ascells, re-assembled into frames and processed to accomplish egress specific encapsulation as well

as per service egress QoS, filtering and accounting functions.

A CPU section manages the forwarding hardware in each Flexible FastPath complex and

participates in the distributed control plane used in the system.

The Chassis Control Module (CCM) is located on the front of the 7750 SR. The CCM accommodates

up to six compact flash memory cards (three per CFM) that can be used to copy and store system

boot, software images, and configuration files and logs. The CCM provides the console and

management interfaces to the 7750 SR as well as alarm information for the CFM and power supplies.

The CCM supports the following external system interfaces: compact flash slots, console ports,mgmt ports, alarm indicators and system LEDs.

For compatibility a set of 7750 SR Media Dependent Adapters (MDA) are equally supported through

the use of the Media Carrier Modules (MCM-XP), which slots into two compact media adapter slots.

Product Overview

The SR-12 Shelf

SR-12 features:

Slots for up to ten IOM cards

Two hot-swappable SF/CPM cardslots; 200 Gbps or 500 Gbps SF/CPMcards available

Up to twenty hot-swappable MDAs

Hot-swappable cooling fans

Switch fabric/control redundancywhen two SF/CPMs installed

Power redundancy when two powersources are connected

The SR-12, with 12 vertical slots, is the largest of the Service Routers. The chassis weighs

approximately 73 lbs (33 kg) and fits into a standard 19 inch rack.

The 2 slots in the middle are reserved for two SF/CPM cards. Two SF/CPM cards provides for full

switching and control redundancy. The remaining 10 slots are available for IOM cards. Each IOM

card can hold two MDAs.

All the modules (SF/CPM, IOM, MDA, cooling fans, air filter and power modules) are hot-swappable,

field-replaceable units.

Note: There are two different versions of the SF/CPM module: SFM2 and SFM3. The SFM2 initially

included two variations: SFM-400G for the SR-12 router and SFM-200G for the SR-7 router. These

SFM modules have 500G and 250G capacity, but when these SFMs were named, the line cards could

only utilize 400G and 200G of the capacity, respectively. The SFM-400G has subsequently been

renamed SFM-500G.

Product Overview

Small Form-Factor Pluggable (SFP) optics

Features: Hot-swappable Only the required SFPs need to be installed

Mix and match different types on a single MDA Some Alcatel-Lucent SFPs have Digital Diagnostics Monitoring capability

including: Temperature Supply voltage Transmit (TX) bias current TX output power Received (RX) optical power

Small Form Factor Pluggable Interfaces

Small Form-factor Pluggable (SFP) transceivers are small optical modules available in a variety of

formats.

Alcatel-Lucent strongly recommends the use of SFPs that are tested and verified by Alcatel-Lucent.Alcatel-Lucent programs its SFPs with the optics type and part number. This enables an operator to

easily determine the SFP type and replacement part number when troubleshooting.

The use of Small Form factor Pluggable (SFP) optics enables further flexibility in populating MDAs

with the required optics on a per-port basis. The combination of hot-pluggable MDAs and optics

means that carriers can defer much of the capital expense of each PoP customer interface until a

firm order for service is received.

The slide above shows three levels in the hierarchy:

MDAs and IMMs provide the physical interfaces that receive and send the traffic over the links

connected to those interfaces. The interfaces can be Ethernet, SONET/SDH, ATM/Frame Relay orchannelized SONET/SDH

IOMs perform all the encapsulation and data plane forwarding operations for packets entering

(ingress) and leaving (egress) the interfaces. The IOM Flexible Fast Path Complex, under the

control of the IOM CPU, determines how packets are handled

The SF/CPM has two functions:

The Switch Fabric (SF) switches packets among the IOMs based on decisions made by the IOM

flexible fast path.

The Control Processing Module (CPM), a dual processing complex, is the main control center of

the router. It is the control plane manager and makes control decisions that are then passed

down to the IOMs. The CPM functions include system control, centralized routing protocol

processing (to update the IOMs in case of a change), and management.

The FIB is stored on the Flexible Fast Path processor. The FFPP provides hardware-accelerated assistance inthe lookup of IP addresses within the FIB.

The Flexible Fast Path Complex consists of:

1. The Ingress and Egress Traffic Manager (TM) with memory Receive packet fragments from the MDA for multiple streams and re-assembles these into frames

Implement QoS policies

Pull scheduled frames from buffer memory, segment them into cells and output them

2. Network processors

Performs all of the QoS classification, destination determination, encapsulation and ACL filterprocessing

It is completely programmable so modifications to any supported forwarding standard can beaccomplished with a firmware upgrade

The network processor supports external Content Addressable Memory (CAM) for storing ACLs andother data

It also supports external memory for storing search trees, statistics, and other data

Local processor on each IOM:

Controls processing of local Forwarding Information Bases (FIB) stored on each IOM Manages forwarding tables and ACLs stored in each flexible fast path

The IOM local processor is considered part of the distributed control plane, responsible for controllingthe processes that help forward traffic

The local CPU also manages the MDA ports and channels, gathers statistics and billing data and providesthe CPM with all necessary information on received control plane data over the ingress interfaces

The fabric access device (FA) connects the Flexible FastPath complexes to the switch fabric.

The SF/CPM consists of:

1. The Switch Fabric with Switching Elements (SE)

2. The Fabric Access that connects the SF with the Traffic Manager

3. The Traffic Manager

4. The Network Processor and memory

5. CPUs with memory

Switch Fabric - The fabric is available in two versions, 200 Gbps or 500 Gbps, both providing full-duplex switching. The SR switching elements are designed with the added ability to schedule

traffic on each egress port independently of all other ports. This feature is important to

operators who want granular control over ingress to egress port traffic scheduling, enabling

them to guarantee traffic rates between each connection point.

Fabric Redundancy - Each switching element (SE), along with its associated serial links, is totallyindependent from all others. On nodes with two SF/CPMs installed , both fully operational

fabrics load share traffic. If a switching element or any of its serial links fail, only traffic passing

over that link or SE at the time of the failure is affected. In most cases this will have no effecton traffic flow, as the switching capacity of each fabric equals or exceeds the total bandwidth

required to support all installed IOMs.

Processing Complex - Responsible for the systems control plane processing and protocol stacks:

1. The SEs receive data from the IOMs and forward it to the traffic manager (TM)

2. The traffic manager forwards the data to the network processor (NP). The SF/CPM memory

buffer packets awaiting processing

3. The network processor pre-processes and prioritizes the packets so that the CPUs process

protocol or time sensitive packets first, followed by less urgent traffic

Control Plane Traffic

Data Plane Traffic

Control Plane and Data Plane

An important principle to understand is the difference between a routers control plane and data

plane.

The control plane is responsible for managing functions that include configuration operations,

routing protocols like OSPF and BGP, management interfaces like serial ports, telnet, and SNMP as

well as error handling and logging. The control plane assures the proper operation of the router as

configured by the administrator. Control plane traffic is overhead necessary for correct data plane

functionality.

The data plane focuses on the actual data traffic traversing through the network. It collects

packets at the ingress, performs a deep-packet inspection which provides a next-hop decision

(distributed in advance by the control plane) for the packet to egress accordingly. This process,

which includes encapsulation conversion, runs at wire speed.

Packets handled by data plane tasks usually travel through the device (router), while packets

handled by control plane tasks usually originate or terminate at the device.

Features/ScalingIOM SupportChassisMode

7750 SR-7 & SR-12

Depending on the chassis type and IOM type, the following modes can be configured:

Chassis Mode A: This mode corresponds to scaling and feature set associated with iom-20g

Chassis Mode B: This mode corresponds to scaling and feature set associated with iom-20g-b

Chassis Mode C: This mode corresponds to scaling and feature set associated with iom2-20g

Chassis Mode D: This mode corresponds to scaling and feature set associated with iom3

When configuring a chassis mode, use Chassis Mode that aligns with the earliest generation of IOM

installed. If the chassis mode is not explicitly provisioned in the configuration file, the chassis will

come up in Mode A by default. In Mode A:

iom-20g-b comes online if provisioned as iom-20g or iom-20g-b

iom2-20g comes online if provisioned as iom-20g, iom-20g-b or iom2-20g

iom-10g comes online if provisioned as iom-10g

iom3 comes online if provisioned as iom3

Note All IOMs must be IOM3 in order to configure chassis mode D.

1000BASE Ethernet MDA which supports 10 pluggable Optical SFPs

Supports up to 20,000 SAPs/Subscribers and up to 8,000 services on the iom2-20g

Extensive on-board queuing and buffering with either service scheduling classes per service on

the 7750SR translating to 160,000 ingress and 160,000 egress queues

The IOM3 supports up to 25G/MDA therefore some MDA Types which are considered to be

oversubscribed on the IOM2 are non-oversubscribed on the IOM3. For example the 2 port, 10

Gigabit Ethernet MDA Type is non-oversubscribed on the IOM3 and oversubscribed on the IOM2.
