Avaya, alongside Leeds Beckett University, will look at a better way to build the smart campus and ready it for the agility and security demands placed upon it by the IoT. Can vastly reducing the number of protocols required to build a campus network lead to reduction in complexity and simultaneously increase security, agility, resilience and performance?

The Benefits ofVirtualization
Server Virtualization
Allows aggregation of multiple
independent virtual servers to exist
on a physical server
Network Virtualization
Decouples the physical infrastructure
from the connectivity services making
the network adaptive and dynamic
with simple one-touch provisioning

6. 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.”

One wrong move ….and the stack collapses!

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 aVirtual 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)

Today’s Network is Inconsistent and Complex
There is a BetterWay…

9. How It Works
Today, each network switch is its
own island of control
Packet processing is
end-to-end
1. Only FabricConnect
header read
2. Sent to next
shortest hop
Packet contents Concealed
Packet processing is
box-by-box
1. Packet contents
inspected
2. 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

11. 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
