The Benefits of Virtualization

Server VirtualizationAllows aggregation of multiple

independent virtual servers to exist on a physical server

Network VirtualizationDecouples the physical infrastructure from the connectivity services making

the network adaptive and dynamic with simple one-touch provisioning

Network Virtualization enabled via Shortest Path Bridging

Status Quo

Complexity Agility

Today’s networks are based on too many protocols causing instability, slowing down recovery times and ability to troubleshoot issues

“Protocols are killing us. Protocols are like the never-ending bottle of pills, each one prescribed to remedy the problems introduced by the previous medication.”

Shortest Path Bridging - Fabric

» Important Properties› Shortest path based on link metrics with no

blocked paths› Reverse Path Forwarding Check (RPFC) eliminates

loops› Symmetric data path between any two nodes

provides ability to leverage Ethernet based OAM CFM/Y.1731 standards

› Unicast path calculated from every node to every other node

› Ability to calculate service specific multicast delivery trees

› No IP configuration required inside the Fabric› Network becomes a Virtual Switched Fabric

Unified Management

IS-IS forms adjacencies to neighbouring nodes, discovers the core network topology and then automatically calculates shortest paths from itself to every other node in the network.IS-IS programs forwarding entries (FIB) in the Backbone VLANs (BVIDs)

Status Quo

Today’s Network is Inconsistent and Complex

There is a Better Way…

How It Works

Today, each network switch is its own island of control

Packet processing is end-to-end1. Only Fabric Connect

header read2. Sent to next

shortest hop

Packet contents Concealed

Packet processing is box-by-box1. Packet contents

inspected2. Compared against

manual routing tables

3. Routing rules determine next hop

4. Segmentation occurs at each box

Packet contents exposed

With SDN(fx), the control function is abstracted from each box into one virtual distributed

control plane

Outages Due to Human Error

Network Services simply delegated to the fabricNo human touch in the

Game-Changing Functionality

The case for SPB

Fast

Flexible

Secure

• Provision at the “edge”• One Configuration Command• Optimized Link State Protocol• Fast to Converge, heal,& add, delete, move services

• Extend services anywhere seamlessly• True service virtualization with ease• L2, L3, Multicast, VRFs…

• As much service isolation as needed• Carrier type virtualization, zero complexity• Network Invisibility to users

Challenge Value Avaya Difference• Large flat network to

segmented network issues• STP not being suitable• How to securely support 3rd

parties

• Ability to span services across entire campus

• Resiliency improved• Dedicated campus wide

VSN for 3rd parties

• Secure isolated IP networks without added protocols

• Simple end point provisioning• Ability to make changes

quickly and easily
