Today‘s Network Paradigm – IP-VPN & IA

Enterprise Service Provider

PE Router

CERouter

Firewall AGG

L2 L3 = Transport Layer

Require a “Network Solution” to simplify and add scale

• Service providers want to offer value added managed services

• OPEX blocks service provider revenue opportunity

• Commoditized, low value

• Complex & high OPEX

• Difficult to upsell add-ons

Status Quo

TGV and NFV...

• Capable of hosting innovative solutions

• But compromised value creation

Legacy Infrastructure

• Optimized infrastructure unleashes true value

Prepared for Innovation

... benefit from an optimized infrastructure

The Virtual CPE Model

ClassicL2 NID AGG

Enterprise Service Provider

Centralization of complex network functions

L2 L3

Simplified connectivity network

PE Router

Logical Subscriber Link (LSL)

Challenges: (1) security, (2) end-to-end service OAM ( IP Layer)

(3) increased bandwidth in access (4) latency, scalability

• Simple CPE equipment

• Fast service roll-out

• Outsourcing opportunity

L2 Encryption Addresses Security Challenge

AGG

Enterprise Service Provider

FSP 150 Pro

PE Router

L2 EncryptionLSL

Securing the access to the cloud

• End-to-end encryption of EPLs with existing Ethernet networks

• Hop-by-hop MACsec with greenfield scenarios

• Full site security

• Uncompromised

transparency

• Runs over any Eth access

L2 Encryption

Enterprise Service Provider

L3/4 OAM Addresses Assurance Challenge

L2 SOAM (Y.1731) for access

L3 SOAM (TWAMP) for end to end service monitoring

Service SLA monitoring from customer port to customer port

• SLA management needs to be provided in the NID

• SOAM at IP Layer requires a L3 monitoring protocol

• End-to-end performance

monitoring

• L2 and L3 services

Etherjack SLA Monitoring now includes L3 Services

Enterprise Service Provider

Programmability Addresses Efficiency

Prevent internal LAN Traffic from being backhauled

• L3/4 ACL, local forwarding of inter VLAN traffic

• SDN controller or VNF appliance driven using standard, open protocols

• LAN traffic stays in

enterprise premise

• Full service control from

central vCPE platform

Programmable connectivity network

Programmability Demo Shown at SDN and OF World Congress 2014

iBGP

OpenFlow 1.3CE Router

Resource optimization by reducing access to core traffic

• Flows controlled by central SDN controller having reachability information

• OpenFlow protocol used for populating forwarding tables

Enterprise Service Provider

Edge VNF-Hosting Addresses Latency, Scalability

PE Router

FSP 150Pro (VM)

NFV-enabled NID with integrated server and storage resources

• Optimize utilization of network, server and storage resources

• Supporting edge-hosted VNFs by PNFs (Physical Network Functions)

• Latency, performance,

scalability suggest edge

hosting

• Open support for VNFs

hosted at customer site

Central and edge hosting

Standard Protocols and Open-Source Control Address Operational Complexity

Open control/programmability

Open orchestration

Open VNF hosting

Evolutionary development from monolithic single vendor to open service-centric network platforms

• Vendors: specification bodies and industrial alliances

• Service providers: PoCs, system integration and DevOps capability

• Three dimensions need to

be considered

• Efficiency gains even with

initial steps

Openness is key
