2 What is a PON A passive optical network is a point-to-multi-point architecture for delivering last-mile connectivity without any active components in the distribution network. A Passive Optical Network consists of an optical line terminator (OLT) located at the Central Office (CO) set of associated optical network units-onus, (or optical network terminals-onts) located at the customer s premise. optical distribution network (ODN) comprised of fibers and passive splitters or couplers for connectivity Information Flows Downstream Point to multipoint (P2MP) Upstream Shared #14 3 FTTx Fiber To The x (FTTx) x = H = Home x = C = Curb or x = N = Neighborhood x = P = Premises x = B = Business or x = O = Office * *From: Gerd Keiser, FTTX, Concepts and Applications, Wiley, 2006 #14 4
3 PON Topologies From: Glen Kramer and Gerry Pesavento, Ethernet Passive Optical Network (EPON): Building a Next-Generation Optical Access Network, IEEE Communications Magazine, February 2002 #14 5 PON Advantages/Disadvantages Advantages Increase bandwidth to Gb/s or higher in the future using multiple wavelengths Increase reach between CO and customer Reduce fiber cost, one fiber to OTL to optical splitter Support downstream broadcast Analog video Digital Video Video over IP Reduce cost via use of passive Disadvantages Cost Need to deploy new infrastructure replace copper with fiber #14 6
4 Types of PONs A/BPON ATM Based PONs/Broadband based PONs Based on ATM technology Two downstream wavelengths (1550nm and 1490nm) and one upstream wavelength (1490nm). The 1550nm channel will be used for an RF or IP video overlay. ITU standard G.983 GPON Gigabit PONs Shares up to 2.5Gbps shared bandwidth among 32 users; Uses same wavelength plan of BPON. ITU standard G.984 Main attribute supports multiple protocols ATM, Ethernet TDM EPON Ethernet Based PONs All data encapsulated in Ethernet frames (note customer premises equipment dominated by Ethernet interfaces) One downstream wavelengths (1550nm) and one upstream wavelength (1310nm). Shares 1.25Gbps in shared bandwidth GigaEthernet PON (GePON) increases shared bandwidth to 2.5Gbps. IEEE 802.3ah VLAN (IEEE 802.1Q) Prioritization (IEEE 802.1p) GPON and EPON are currently the major alternative technologies focus here is on EPONs #14 7 Types of PONs #14 8
5 EPON Downstream flows Note ONU can be associated with multiple users Passive Splitter Number of users typically limited to 64 splitting loss Modified from: Glen Kramer and Gerry Pesavento, Ethernet Passive Optical Network (EPON): Building a Next-GenerationOptical Access Network, IEEE Communications Magazine, February 2002 #14 9 EPON Upstream flows ONU/OLT distances vary - Need power control - Guard times to overcome sync errors All ONUs are in time sync Time slots can carry multiple Ethernet Frames Permission to send in a time slot done by the OLT using a Multipoint control protocol (MPCP) Modified from: Glen Kramer and Gerry Pesavento, Ethernet Passive Optical Network(EPON): Building a Next-GenerationOptical Access Network, IEEE Communications Magazine, February 2002 #14 10
6 MAC Protocols Initialization-auto-discovery mode Ranging MAC address Synchronization Assign Logical Link identifier (LLID) EPON is treated as a collection of logical point-to-point links by higher layers Reserved #14 11 From Glen Kramer, Ethernet Passive Optical Networks, McGraw-Hill, 2005 #14 12
7 Multipoint Control Protocol (MPCP) Normal Mode OLT sends a GATE message to give ONU access to transmit ONU sends a REPORT message to tell the OLT its state, e.g., buffer contents * *From: Jun Zheng and Hussein T. Mouftah, Media Access Control for Ethernet Passive Optical Networks: An Overview, IEEE Communications Magazine, February 2005 #14 13 Example From: IPACT: A Dynamic Protocol for an Ethernet PON (EPON) Glen Kramer and Biswanath Mukherjee, Gerry Pesavento, IEEE Communications Magazine,February 2002 #14 14
8 MPCP-Normal Mode From: Michael P. McGarry, Martin Maier, and Martin Reisslein Ethernet PONs: A Survey of Dynamic Bandwidth Allocation (DBA) Algorithms IEEE Communications Magazine, Vol. 42, No. 8, pages S8-S15, August 2004 #14 15 MPCP-Normal Mode Uses a polling like mechanism, i.e., cycle based Higher layer at OLT instructs the transmission of a GATE message to ONU i, containing Time stamp Granted start time Granted transmission window ONU i receives GATE message Synchronizes clock (avoids collisions in the up stream) Transmits at the start time Continues to transmit up to the granted window Transmission opportunity may send multiple Ethernet frames (variable length) REPORT message included in the transmission window No fragmentation is allowed #14 16
9 MPCP-Normal Mode REPORT message Time stamp Bandwidth demands of the ONU OLT receives the report and allocated bandwidth #14 17 MPCP-Normal Mode Each ONU is polled once in a cycle Upper limit on the granted transmission window controls Maximum bandwidth allocated to ONU Insures all ONUs have an opportunity to transmit There can be different polling policies #14 18
10 MPCP-Normal Mode Poll and stop Like master slave Receive REPORT before generating next GATE No ONU sync needed Poor throughtput Interleaved Polling Send GATE before receiving the REPORT OLT does not have upto date ONU state information Interleaved polling with stop Use all reports in previous cycle to determine allocations in next cycle * *From: Jun Zheng and Hussein T. Mouftah, Media Access Control for Ethernet Passive Optical Networks: An Overview, IEEE Communications Magazine, February 2005 #14 19 Bandwidth allocation in the OLT DBA Algorithm Transmission scheduling-options Round Robin Descending order of reported queue length largest queue first (LQF) Dynamic allocation #14 20
11 Dynamic Bandwidth Allocation Interleaved Polling with Adaptive Cycle Time (IPACT), Define- n = cycle number G(n) = Grant window Q(n) ONU buffer size (backlog) that will be served during G(n) Q(n) generated at instant ONU generated REPORT message Q(n) is used to calculate the grant window size in next cycle, G(n+1) #14 21 Dynamic Bandwidth Allocation Interleaved Polling with Adaptive Cycle Time (IPACT) If Q(n) = 0 OLT still generates GATE Allocation methods Fixed service: Always gives Maximum transmission window (MTW) Limited service: Window size is set to Q(n) up to the limit of MTW #14 22
12 Dynamic Bandwidth Allocation Interleaved Polling with Adaptive Cycle Time (IPACT)-allocation methods continued Constant Credit service: Window size is set to Q(n) + credit Accounts for packets arriving to the ONU after REPORT sent Credit too big wasted BW Credit too small increase delay Linear credit: similar to constant credit, but the size of credit is proportional to the requested window Elastic Service Maximum cycle time is enforced = N*MTW; N= #ONU No limit on MTW per station Accumulated size of last N grants < N*MTW A backlogged ONU could get a grant of N*MTW #14 23 Interleaved Polling with Adaptive Cycle Time (IPACT) W_max=15,000 Bytes BW= 600 Mb/s Max transmission window = 2 ms Guard time= 5 us From: IPACT: A Dynamic Protocol for an Ethernet PON (EPON) Glen Kramer and Biswanath Mukherjee, Gerry Pesavento, IEEE Communications Magazine,February 2002 #14 24
13 Dynamic Bandwidth Allocation Problem: Traffic arrives at ONU after REPORT sent but before GATE arrives, OLT dose not know about this traffic Let A(n-1) = traffic arriving between request for n-1 cycle and the grant for the n th cycle D(n) = G(n) [Q(n-1) + A(n-1)] Grant based on G(n+1) = G(n) αd(n); for stability 0<α<2 Control loop has to be desinged to be stable and avoid excessive oscillations #14 25 Bandwidth guaranteed polling: (BGP) Divided ONUs into two disjoint sets: bandwidth guaranteed Non-bandwidth guaranteed (best effort) Bandwidth guaranteed nodes are characterized by their service level agreement (SLA) with the network provider Upstream capacity is divided into equivalent bandwidth units, e.g., Upstream capacity = 1 Gb/s N = 64 equivalent bandwidth unit = 10 Mb/s Then there are 100 equivalent bandwidth units OLT has two tables ONUs with guaranteed bandwidth # rows = # bandwidth units ONUs without guaranteed bandwidth Not fixed Rows in guaranteed bandwidth table can be used for best effort ONUs OLT polls best effort ONUs in order they appear in their table and during time allocated for empty rows in guaranteed bandwidth table #14 26
14 Bandwidth guaranteed polling: (BGP) # rows = Total # upstream bandwidth units, e.g. 100 OLT pools ONU in BW guaranteed list, if empty then polls the rows in the BE table Best Effort Table From: Michael P. McGarry, Martin Maier, and Martin Reisslein Ethernet PONs: A Survey of Dynamic Bandwidth Allocation (DBA) Algorithms IEEE Communications Magazine, Vol. 42, No. 8, pages S8-S15, August 2004 #14 27 Intra-ONU queueing and scheduling Approaches OTL can control REPORT messages in status in each queue, MPCP supports up to 8 queues GATE then responds for a specific queue ONU can control REPORT message relfects aggagerate state of the ONU ONU schedules transmissions Strict priority Non-strict priority #14 28
