  1. Intra-NE Routing Mechanismdraft-guo-forces-routing-01.txt Xiaoyi Guo(xiaotian@huawei.com) 64th IETF Meeting, Vancouver

  2. Forwarding mechanism Motivation • One NE may include many CEs and FEs, one of the forwarding path may cross many FEs ,not cross only one FE. • FEs should not know all the topology of the NE, so the routing table in FEs should not include all the NE routing information.

  3. CE Forwarding mechanism 2 routing tables in CE -- Edge FE Intra-FE Edge FE FE1 FE3 FE2 Intra-NE RT RT

  4. Forwarding mechanism Data forwarding • ----- Edge FE ----FE ---Edge FE -- • ( RT ) ( Intra-NE RT ) ( RT ) • We focus on Intra-NE forwarding mechanism

  5. Forwarding mechanism Routing table construction: • CE side: SPF algorithm Full topology --------- Intra-NE Routing Table routing protocols Routing information ----normal Routing table • FE side : CE send RT to each FE , not the full routing table

  6. Next .. • Consideration about the security? • Could one hop forwarding use this mechanism ? • Need the new LFBs construction? • More details of this mechanism need to considering and working out ….

  7. Other questions? • Interested in this work?

  8. Please send your comments to me and ForCES mailing list.
