Appliance and Ecosystem Where will NFV deploy first – Core carriers are moving now, but complex migration – BSS/OSS has to be maintained – Refine troubleshooting and scaling techniques – Need reason to move from deployed systems Enterprise networks simpler to move – Site by site migration possible – App by app migration – Less OSS/BSS complexity

Branch Office Which appliances can be virtualized?

Virtual Appliances Many flavors depending on deployment SERVER H/W HYPERVISOR SWITCH OS and APP Orchestration

Network Architecture Centrally managed and controlled VMA can be distributed or centralized Flexible forwarding Faster deployment Combined licensing Coordinated workflows Distributed functionality

Ecosystem Players Hardware: Intel, Cisco, Juniper, IBM, Dell, OCP VMs: Xen, Hyper-V, VMWare, KVM OS: Linux, Unix, WinServer 2008 Applications: Citrix, Cisco CSR-V, Asterisk, IBM, Sansay, Fortinet, Adtran, many others Orchestration Layer: OpenStack, VCloud, VCenter, VFrame VM does not mean open source

Who leads? Depends on business goals Enterprise businesses – Call Center ----> PBX/Application – Mfg -----> File server ERP and Control Systems – Retail, engineering, financial would be different Telcos: LEC or Next Gen? – Mobile and Cable MSO? – Driven by BSS/OSS orchestration

FlowVUE 18 ©2012 Gigamon | Corporate Overview | Company Confidential Turning Big Data in to Manageable Data SMARTer option to address Big Data –Enable carrier to selectively reduce traffic –Deterministic results at a fraction of the data rate Address rising tool costs –Preserve or increase CEM based on real-time reduced data analytic throughput Leveraging Big Data as a competitive asset vs overwhelming burden –Tailoring pricing strategies based on usage patterns and guarantee SLA’s on premium level content. –Enhanced Visibility facilitate efficient transparent billing and accounting. Tool Vendor Agnostic Solution –Working in Carriers interest –Visibility vendors tied to tool vendors - primary goal is to sell monitoring tools –Leading US carrier sees this approach as the only way forward for managing Big Data
