Longer paths definitely, increased jitter probably, increased latency
probably, increased loss possibly.
In general, as companies and backbones merge and eliminate "old" ASNs, that would reduce the overall AS path length. That in general should not affect latency but as tier-1 ASNs grow in size, and control more of the path end to end, the latency should improve. The majors/tier1s like AT&T, UUnet, Genuity and C&W provide SLAs "end-to-end" *within* their ASN. They control the pipes, they know what they can take and they don't have to worry about some overloaded peering link. So as consolidation takes place, we should see better latencies and better SLAs.
