It is designed to be deployed in medium-sized aggregation and large mobile macro sites as well

as controller and S-GW sites in technically advanced all-IP networks It provides the flexibilityand capabilities to serve all-IP mobile and fixed networks including applications ranging fromtraditional consumer, enterprise and machine-to-machine connectivity to cloud networking needs

It has interface density, throughput and cost effectiveness to meet the needs of fast growing dataservices, while maintaining high quality for the low latency voice traffic The 8665 Smart Routerprovides ideal capabilities to implement flexible LTE network architectures The 8665 Smart Routersupports both fixed and mobile transport, so mobile operators can extend their service offering toinclude also e.g fixed business services

As cell site and business user capacity requirements are growing to several hundreds of Megabitsper second, Gigabit Ethernet interface becomes the de facto standard as an access interface Thiswill set new requirements for aggregation networks where dense 10GE interfaces and 100 GEinterfaces will be required

The 8665 Smart Router can function in the following roles:

• 10 GE or 100 GE Ring member

• Direct 1GE or 10GE access to cell sites or business customer sites

• Dual homed aggregation site

• 1X100GE (CFP2) + 24X1/10GE SFP+/SFP with two operating modes:

• Mode 1: 1X100GE (CFP2) + 14X1/10GE (SFP+/SFP)

• Mode 2: 24X1/10GE SFP+/SFP

• In a fully populated Line Unit four 10GE/1GE interfaces need to be in 1GE mode inthe initial release

• The option to use all ports (1X100GE + 24X1/10GE) simultaneously is not supported

• Line Unit forwarding performance with IMIX packet distribution

• When single operational Switch Unit is present the forwarding performance is 130Gbit/s

• When two operational Switch Unit is present the forwarding performance is 200 Gbit/s

• Chassis size: 15 RU high, 420 mm deep, 19 inch rack mounting

• Forced cooling with replaceable fan modules and filter unit

• Temperature range +5 °C 45 °C / 41 °F 113 °F

• Front to back airflow allows cold aisle/hot aisle site layout

• User changeable redundant -48 VDC power supply

• Maximum power consumption 1700W (first generation Line Units and Switch Units)

• Power redundancy

• Switching redundancy

• Control Plane redundancy

• 780 Gbps / 1.2Tbps throughput with IMIX packet distribution

• When single operational Switch Unit is present the throughput is 780 Gbps and with twoSwitch units 1.2Tbps

• Backplane scales up to 3Tbps

• IP VPN (RFC 4364)

• (H)-VPLS (RFC4762)

• Ethernet/VLAN pseudowire (RFC 4448)

• All 8600 routing and signaling protocols: OSPF-TE, IS-IS-TE, MP-BGP, LDP, RSVP-TE

• L3/L4 Access Control Lists

The 8665 Smart Router has been optimized to be installed in 600 mm deep 19” racks The depth

of the NE is 420 mm to allow good room for fiber installations and room for cabling behind thenodes also

The 8665 chassis can be equipped with up to 6 Line Units and with two switch cards Switchcards are installed in the middle slot, one on top of the other, leaving six slots for Line Unit cards,three on each side of the switch unit The card slot width is about 60 mm, which allows three SFPcages side by side on the front plate This means very high port density on the front plate All theseven slots in the chassis are the same width

The 8665 Smart Router is 15U high and designed for front to back airflow Three 8665s can beinstalled into a single 45 RU cabinet without extra space between them

• Storage: ETSI EN 300 019-1-1, Class 1.1 Temperature: -5 °C to 45 °C / 23 °F to 113 °F.

• Transportation: ETSI EN 300 019-1-2, Class 2.3 Temperature: -40 °C to 70 °C / -40 °F to 158

°F

• The enclosure class is IP20

• The air from the NE, which can come into contact with equipment cables in maximum ambientconditions shall not exceed +75 °C / 167 °F according to [ETS_300119-2]

3.3.2 DC Power Supply

The 8665 Smart Router requires 48 DC input voltage Maximum input power is 3 kW This allowsfuture development of new Line Units that may need more power The 8665 Smart Router hasredundant power modules

In 8665, virtual CU process runs on LU cards If the LU card having the active CU role fails,the node performs two actions simultaneously:

• Traffic re-routing for traffic destined to ports in the failed LU card

• Performing CU switchover to another LU

The CU switchover can delay rerouting of the traffic There are three types of traffic impacts:

• No impact to traffic not destined to the failed card

• Any hard-real-time (RSVP-TE FRR, BGP MP, ELP, ECMP, some cases of RSVP 1:1) protectedtraffic destined to the failed card experiences normal protections switch with the same perfor-mance as with regular line card failure (e.g <50ms, <200ms, <300ms, etc, per technology limit)

• Non-protected routed traffic (LDP LSPs, non-ECMP OSPF/IS-IS, non-MultiPath BGP, tional cases of RSVP 1:1) may experience some delay (typically 15-45s) before normal re-rout-ing actions are performed

The 8665 Smart Router runs the same 8600 operating system as the other routers in the series You

can find information about the supported element management functions in 8600 Smart Routers

Management Communications Configuration Guide.

3.5.1 Node Communication Protocol

The 8600 system products can be reached for management and configuration purposes via TELNET,CLI, BMP, FTP, SNMP, RADIUS, TACACS+ and SSH protocols The 8665 Smart Router supportsprotocol and information model that can be used by intelligent network management (BMP) BMP

is the primary management protocol for configuration and monitoring Usage of the 8000 IntelligentNetwork Manager (8000 INM) simplifies the network management by bringing tools that simplifythe operation of the network SNMP support is limited to read-only information and therefore itcannot be used for network element configuration SNMP is used for faults and statistics

Centralized RADIUS and TACACS+ server is supported and it can be used to provide additionalsecurity by performing user authentication Configuration change notifications (CCNs) are used forIncremental discovery at system level with NE–8000 INM The NE reports to 8000 INM what hasbeen configured using CLI

The 8665 Smart Router supports the following Ethernet protocol encapsulations:

Limitations and Restrictions in QinQ Interface

• C-VLAN ingress QoS classification

• If classification is done based on VLAN PRI, then S-VLAN PRI bits are used

• Marking CoS to S-VLAN only (transparent C-VLAN CoS)

• Both S-VLAN and C-VLAN are marked or both are transparent

3 8665 Smart Router

• QinQ interface not supported with MAC switching, VPLS and IRB

• Note that QinQ frames are supported, but actual QinQ interface that terminates two tags isnot

• Seamless MPLS

• Seamless MPLS cannot run on top of QinQ interface

• QinQ interface on LAG is not supported (LAG.S-VLAN.C-VLAN)

• Ethernet PW redundancy

• IP load balancing to RSVP-TE tunnels

• The packets from QinQ interfaces are not load balanced

• Policing and shaping on C-VLAN level

• Policers or shapers cannot be associated to QinQ interfaces

• Policer or shaper associated to S-VLAN is applied to QinQ packets as well

3.6.2 Ethernet Link Aggregation 802.1AX

The 8665 Smart Router implements Ethernet Link Aggregation (LAG) [IEEE 802.1AX]

functionality for 1GE and 10GE links

Ethernet Link Aggregation (LAG) [IEEE 802.1AX] is a method for bundling Ethernet links so thatthey appear to upper layers as one higher-capacity Ethernet link Traffic is distributed to the memberlinks by a load balancing algorithm The maximum number of LAG members is eight

The benefits of Ethernet Link Aggregation include:

• Increase of Ethernet link bandwidth beyond the bandwidth of a single physical link

• Interface protection by means of load balancing; if one of the member links fails, load balancing

is automatically re-configured so that the remaining links carry the traffic

Limitations and Restrictions in LAG Interface

• Pseudowire redundancy

• LAG cannot be used with IRB

• Multi-card LAG is not supported in 8600 Smart Routers SR7.0

• QinQ
