Frontier Overview
•Our Mission To be the leader in providing communications services to residential and business customers in our markets
Frontier Overview
5th‐largest domestic telecommunications provider
15,000 employees – 100% US‐based.
Acquired operating areas in 14 states from Verizon in 2010.
Frontier now operates in 27 states overall.
The acquisition tripled the overall size of Frontier’s market space.
The acquisition quintupled the size of Frontier’s Business market space.
•Our Mission To be the leader in providing communications services to residential and business customers in our markets
Key Points on the Current Status
Frontier is building out 1000+ locations of ROADM t k t i f th t t k dnetwork to reinforce the current network and
relieve congestion.
B ildi t l l d i t E C tBuilding out local devices to serve EoCu customers as well as EoFOC.
L 2 it hi i bi ti f ld dLayer 2 switching is a combination of old and new.
Frontier is finishing up a systems consolidation to d ith th V i tdo away with the Verizon systems.

What I Need from My Suppliers/Partnersy pp /
Absolute Compliance to Tight Standards• “Generally Compliant” = Mostly Compliant = Non‐Compliant• Nearly 100% of the RFPs we receive require that we reply
with MEF 10 2 1; MEF 12 1; and MEF 15 compliant solutionswith MEF 10.2.1; MEF 12.1; and MEF 15 compliant solutions• Some RFPs also specify IEEE 802.3ah, 802.1, and ITU‐T Y.1731
compliant replies.
There are too many opportunities to which to reply to come up with work‐arounds for non‐standard configurations.

What I Need from My Suppliers/Partnersy pp /
Integrated Monitoring and Control Systems• As slick and effective as your proprietary software may be, I y p p y y ,
cannot ask my NOC to learn yet another piece of software for yet another vendor.If you want to impress us show us your highly functioning• If you want to impress us, show us your highly‐functioning, smoothly integrated API into Netcool.

So… what does the lower layer expects from 100G
4
A Router @100G will need to do it’s traditional function at x10 the speed!
> Strip lower-layer information from an incoming packet
> Queue it
> Perform a route lookup, & send to the proper outbound queue to be Packetized
> Perform filtering
> SLA monitoring and policing
> Class of service / quality of service (CoS/QoS) prioritization
> Exchange per-VPN MPLS label information
> Build multicast routing trees
> Perform routing table updates for multiple protocols
> Maintain statistics and logs (performance, alarm, event and failure)
> Perform firewall and security functions
Business Continuity check List:
Can’t drop packets
Can’t introduce extra Jitter and Latency
Can’t compromise VPN boundaries
Can’t reorder packets
Oh BTW…All Must Happen in IPV4+1PV6 Dual Stack Environment!!

Going into 1T needs “non-linear” thinking & new toolsets
Current 100G to 400G is a linear thinking
The linear approach and current tool sets start to break in 1T architecture
Need for a better solution in the circuit I/Os ..from all E to E+O..
We need E2E Power, Space and Cooling budget..Set the TCO goal now
1T connectivity may not look like Nx25G MLD
Shannon’s limit in fiber requires deeper look at current network architecture…Super Channel is a temporary fix
Industry needs a straw man’s E2E BOM for more than one approach in order to create a baseline for 1T and beyond architecture …
Who? IEEE, ITU, OIF? Disjoint & piecemeal ownership is unproductive
How can we help connecting the dots?
