8 MiM / 802.1ah / PBB >Customer frame is transparently tunnelled from UNI to UNI hiding customer SA in PBB network >Customer separation based on a especial label (I-SID) >Addressing separation: >SP core network only learns UNI MACs >No DoS or MAC explosion 802.1ah Provider Backbone Bridges Payload Ethertype C-VID Ethertype SA DA I-SID Ethertype B-VID Ethertype B-SA B-DA SA = Source MAC DA = Destination MAC VID = VLAN ID C-VID = Customer VID I-SID = Service ID B-VID = Backbone VID B-DA = Backbone DA B-SA = Backbone SA X Y A B MAC X CE PBB network CE MAC Y UNI MAC=A UNI MAC=B

11 Agenda > Network Visions > Carrier Ethernet > Provider Link State Bridging (PLSB) > Summary

12 What is PLSB? > PLSB is a Spanning-Tree Protocol replacement for PBB STP is slow to converge; typically seconds STP blocks links effectively stranding bandwidth > Control Plane IGP + PBT operation MEM not required to achieve deterministic forwarding IGP (Interior Gateway Routing Protocol) IS-IS used to dynamically find the shortest path to the destination PBT like forwarding dynamically updated > Data Plane PBB encapsulation for forwarding B-MACs distributed by IS-IS 12

13 The Current Mode with STP root A X X X The STP protocol distributes bridge PDUs (BPDUs) to compute a single spanning tree. Ports not on the tree are blocked and not used for multicast traffic. Unknown destinations are broadcast, and reverse learning used to build forwarding tables. D 13

14 PLSB Fundamentals > Apply Link State routing to Ethernet, now that PBB has placed all backbone MACs under provider control > flooding is disabled & all ports are unblocked > Control plane configures shortest path unicast and multicast connectivity between PBBs > PLSB delivers a better B-MAC layer for MAC-in-MAC by elimination of the Spanning Tree Protocol : > PBB s MAC-in-MAC keeps C-MAC state at the edge > C-MAC flooding & broadcast maps to scoped B-MAC multicast > Ethernet s network-global identifiers allow all information (B-MAC and Service Identifiers) to be flooded by a single protocol, IS-IS : > PLSB has no link-local state to manage. 14

15 PLSB Implementation PLSB discovers the network automatically setting up a shortest path distribution tree without blocking any links Each node creates its Shortest Path tree to all other nodes in the network Network Topology Shortest Path tree from ES1 15

16 Defining Services using PLSB > As PBB service endpoints (ISIDs) are added, all PLSB nodes will be aware of all service locations. > Each PLSB node will know if it is on the shortest path for each ISID and install the appropriate FIB state to ensure connectivity, thereby creating per service multicast tree 2 16 Shortest Path tree from ES1 Multicast tree for all nodes supporting ISID 100 (ES1, ES7, ES11)

17 PLSB Loop Suppression 17 > In any distributed system transient loops will occur Even transient multicast loops can be catastrophic packet multiplication rate is limited only by the RTT, Ethernet today blocks ports until converged (STP) > PLSB ensures that the path between any two nodes in BEB BEB each direction is the same for both BEB unicast and multicast paths : PB so in a converged network PB PBBN each bridge knows the interface on which to expect any given BEB BEB source; it is already in the FDB > We can trivially modify bridge source learning to audit multicast convergence on a frame by frame basis : need to learn this SA? drop this SA if unknown BEB
