This paper presents ViAggre (Virtual Aggregation), a \u201cconfiguration-only\u201d approach to shrinking the routing table on routers. ViAggre applies to legacy routers and can be adopted independently and autonomously by any ISP. ViAggre is effectively a scalability technique that allows an ISP to modify its internal routing such that individual routers in the ISP\u2019s network only maintain a part of the global routing table. We find that ViAggre can shrink the routing table on routers by more than an order of magnitude while imposing negligible traffic stretch.<\/p>\n","protected":false},"excerpt":{"rendered":"
