2 JUNOSPHERE: NETWORK VIRTUALIZATION IN THE CLOUD Junosphere delivers Junos on-demand via the cloud Enables real network modeling and education using virtual Junos routers Accessed on demand via the Internet to a Juniper-hosted DC Learn, model and test Junos features with the flexibility, costefficiency and simplicity inherent of a cloud based delivery model Internet 2 Copyright 2011 Juniper Networks, Inc.

3 JUNOSPHERE CLASSROOM Junosphere Classroom is the first service offered from the Junosphere Cloud Use virtual networks to provide hands-on education and experience with Junos Universities, technical training institutes; Juniper customers and channel Cloud-based delivery model brings many benefits over physical labs Reduced capital costs no need to purchase networking elements Lower operational costs power, space, cooling and maintenance Increased flexibility rapidly scale up or down Realistic experience exact same Junos running in commercial networks 3 Copyright 2011 Juniper Networks, Inc.

4 JUNOSPHERE COMPONENTS User Interface Accessed via web browser Virtual Machine Manager Create, manage and modify virtual elements and networks Junosphere cloud Juniper-hosted datacenter Virtual Network Elements VJX Series Junos Routers CentOS Other images as needed 5 Copyright 2011 Juniper Networks, Inc.

5 INTRODUCING VJX SERIES VJX Series is a new Junos platform that runs in a hypervisor on standard x86 hardware. Full control plane, management plane and forwarding plane features Includes v6, Multicast, MPLS, L2 & L3 VPNs, full protocol suite VJX1000 is the first product in this series, built to run in Junosphere First release based on Junos 10.3; full alignment with release train starting with Junos 12.1 VJX series product enhancements include More features: Junos switching, BRAS features.. Chassis emulation: Virtual instances of Juniper systems such as MX-Series and SRX-Series Guest OS Guest OS Guest OS VJX VJX N VJX Virtual Machine Virtual Machine Virtual Machine Hypervisor = KVM / QEMU HOST OS = CentOS COTS x86 hardware 6 Copyright 2011 Juniper Networks, Inc.

12 Goal: JUNOSPHERE TRIAL OVERVIEW Replace existing student router testbed with virtualized environment Original environment - 4 testbeds composed of PC s running Quagga and Ethernet switches Cloud.juniper.net provided: 24 testbeds of ten virtual machines (8 Junos, 2 Centos) Enabled much improved student to equipment ratios (3:1 vs 20:1) Distance Learning: Students connecting from UK, Portugal, Spain and China Courseware shared and reused by other Universities in other countries 13 Copyright 2011 Juniper Networks, Inc.

13 ELE403 ROUTING EXERCISE IN JUNOSPHERE Testbed cloned and scaled according to the numbers of students Testbeds spun-up / spun-down in a matter of minutes Impossible to achieve with physical equipment private4 Centos Host private7 private3 Centos Host private9 private5 private1 private8 private2 private6 14 Copyright 2011 Juniper Networks, Inc.
