Agenda

• Enterprise network – Juniper Approach

• Network building blocks

• Fabric solution• Virtual chassis• Virtual chassis fabric• Fusion

• Enterprise networks – two pillars: campus and data center


Enterprise Network – Juniper Approach


Juniper Approach

• One Junos – common CLI, management and reporting

• General purpose vs specialized ones• Keep it simple • Use specialized ones when it makes sense

• Do not create boxes when there is no strong need to

• Think how you scale – investment protection

General purpose vs specialized ones

• Limited number of devices – we are not artificially increasing number of units in our price list

• Data Center – 10GE/40GE/100GE switches are designed for DC (QFX series)

• Data Center – 1GE use of general purpose model (EX4300)

• Campus access – use of 1GE general purpose model (EX4300)

• Campus core – designed for this task (EX4600)

• WAN connectivity – EX9200 or reuse of MX series


Investment protection

• Additional devices can form Virtual Chassis with already installed ones (no links blocked by spanning tree)

• Each new VC member can increase number of available uplink ports

• Data ports can be used for VC connection – longer range and no need to buy special stacking cable or ports

• Not only ring VC topology – full or partial meshed supported (including nonblocking 5 times EX4300 VC)

• EX4300 1GE access switch can be reused in VCF topology as leaf switch

• QFX 10GE DC switch can be reused in VCF as spine or leaf switch

Junos Fusion

Junos Fusion

• Simplicity and resiliency at scale

• Any workload anywhere in data center; workload mobility

• Any type of access from 1GE to 100GE

• 1GE,10GE, 40GE @ FRS

• No proprietary lock in

• Open Standards & programmability IEEE 802.1BR and JSON-RPC APIs

MC - LAG

MC - LAG

• Access devices manages separatly

• Access can be any device type (router, Firewall, load balancer)

• Have to manually keep core devices configuration in sync


Enterprise Networks


Two pillars: Campus and Data Center

• Common• Easy to manage• All active links (no STP)• Easy to grow• Segmentation

• Highly reliability• Investment protection

• Data Center• 1/10/40 GE access• FCoE• Low latency• Overlay network gateways

• Campus• 1GE access• PoE• 802.1X• EEE


Juniper Solution for Enterprise

• Proven by years of dealing with Service Providers – which most Data Center becomes today

• Use common resources when possible

• Highly tailored solution when needed

• Open Architecture

• Open API

• Open Protocols
