Flow Representation and NAT Traversal Flow information traffic selector 4/5-tuple destination address prefix DSCP Open issue: do we allow for multiple traffic selectors? e.g. multiple source/destination port nrs. allow for adding/removing traffic selectors? In case we assume NATs is only NTLP aware Have no IP address/port information at NSLP layer NSLP should use flow information from the NTLP impact on NTLP/NSLP interface If NTLP does proper NAT processing on flow id, does NSLP need to do anything? |
