4 Electric Utility Applications

5 Today s Communication Network Requirements More bandwidth Minimal delay and jitter Legacy technologies + new applications Flexible capacity and speed High resiliency Security

6 IP-centric communications From: Separated service networks To: Converged service network Optimization Simplification All services in one network Each service has its own network A mix of networking technologies Network transformation to provide the required communications foundation for emerging smart grids June 2010

7 Why consider IP/MPLS for Network Solution Current TDM Network difficult to scale? Current Network or segments are out of capacity? Troubleshooting is time consuming? Multiple Networks Multiple Teams? Expensive leased circuits? Consider IP/MPLS as the SOLUTION

8 Reliable Communications with MPLS Standards-based IETF, ITU-T, IP/MPLS Forum A Multi-vendor interoperability Deterministic behavior Connection Oriented approach Similar to ATM/TDM/SONET Resiliency 50ms Fast Re-Route (SONET Like) Active/Standby path provisioning for high availability Protocol Independent Any Layer 2 or Layer 3 protocol runs over it Traffic Engineering More efficient use of network resources Provides service guarantees and resource reservation Supports multiple VPN schemes Emulation of private Layer 2 and Layer 3 networks Inherent Operation & Maintenance capabilities (OAM) Easier to troubleshoot LSP TDM Ethernet IP ATM etc Z IP/MPLS network Pseudowire MPLS Tunnel IP/MPLS network LSP B MPLS Router 8 IP/MPLS Utility Networking

10 What are some of the concerns on IP/MPLS? TDM applications Can MPLS handle legacy applications? How about voice (traditional and VoIP)? How about timing and synchronization? Teleprotection Can MPLS handle the strict latency requirements of Teleprotection? Can it deliver sub-8ms circuits? Security Is MPLS secure? How can it improve security? Management Is MPLS too complex to manage? Migration How can I safely migrate from SONET to MPLS? Cost Is MPLS too expensive? What is the alternative? June 2010

11 Bell Labs: Delay and Priority Requirements for Application Traffic Application Delay Allowance (minimum) ms Priority 0-max 100-min Delay <= 10 ms (High speed) Protection Information* 8, 10 2 Load shedding for underfrequency ms < Delay <= 20 ms Breaker reclosures* Lockout functions* Many Transformer Protection and control applications* System Protection (PMU)* ms < Delay <= 100 ms SynchroPhasor Measurements (Class A) SCADA data poll response PTT signaling (critical) PMU clock synchronization ms < Delay <= 250 ms VoIP bearer (inc. PTT) VoIP signaling (inc. PTT normal) Dynamic Line Rating (DLR) Real-time video (mobile WF) On demand CCTV video Other SCADA operation Enterprise data - preferred Most distribution and SCADA apps AMI - critical Application 250 ms < Delay < 1 s Delay Allowance (minimum) ms Priority 0-max 100-min AMI - priority CCTV stream - normal PMU (class C) Some Transformer Protection and Control Applications Enterprise data - other s <= Delay Image files Fault recorders (Medium speed) monitoring and control information (Low speed) O and M information Fault isolation and Service restoration Distribution applications AMI periodic measurements Text strings Audio and video data streams Fault Recorders Best effort, Default * Traffic for these applications is only between two substations connected with transmission line. This traffic must be designed to be only single hop. Thus the corresponding delay requirements must be considered only single hop. All other delay requirements may have to be satisfied over multiple network hops.

12 TDM over MPLS The two principal services are used for structured and unstructured connections CESoP Circuit Emulation Service over Packet Provides fractional services (nxds0) SAToP Structure Agnostic TDM over Packet Provides unstructured T1/E1 services Two services are collectively referred to as Circuit Emulation Services (CES) Services are transported over an MPLS Network using Pseudowire point-to-point tunnels TDM MPLS Tunnel TDM CES IWF CES IWF The CES Interworking Function (IWF) applies the proper encapsulation to the nxds0 or T1/E1 traffic Pseudowires (PWE3) identify the specific CES connection MPLS Tunnels transport traffic from point A to B Flexible configuration of buffers within the CES IWF allows control of packetization, latency and jitter which meets the requirements for TDM services. 12 IP/MPLS Utility Networking
