Impact of FIB Aggregation on Traffic Offloading
نویسندگان
چکیده
• FIB aggregation • Reduce the size of the Forwarding Information Base (FIB) • Remove redundancy while ensuring forwarding consistency with the original FIB • Traffic offloading • Glue together a hardware-centric forwarding fabric (fast-path) with a softwarecentric route controller (slow-path) • Offload the top-volume FIB entries to the fast-path, handle the remainder at the slow-path • Leveraging Zipf’s law: A small fraction of top IP prefixes carry most of the traffic SYSTEM OVERVIEW FIB aggregation implemented in a traffic offloading system [1]:

Traffic Offloading Impact on the Performance of Channel-aware/qos-aware Scheduling Algorithms for Video-applications over Lte-a Hetnets Using Carrier Aggregation
Long Term Evolution (LTE) is defined by the Third Generation Partnership Project (3GPP) standards as Release 8/9. The LTE supports at max 20 MHz channel bandwidth for a carrier. The number of LTE users and their applications are increasing, which increases the demand on the system BW. A new feature of the LTE-Advanced (LTE-A) which is defined in the 3GPP standards as Release 10/11 is called Car...
متن کاملA Detailed Game-Theoretical Analysis of the WiFi Offloading in Wireless Markets
The rapid advances in networking, mobile computing, and virtualization, lead to a dramatic increase in the traffic demand. A cost-effective solution for serving it, while maintaining a good quality of service (QoS), would be to offload a part of the traffic originally targeted for cellular base stations (BSs) to a WiFi infrastructure. Related work on the WiFi offloading often considers markets ...
متن کاملCatching popular prefixes at AS border routers with a prediction based method
Modern Internet routers require powerful forwarding facilities to cope with extremely high rate Forwarding Information Base (FIB) lookups. In general, the FIB is constrained to a small highly efficient but expensive memory. Unfortunately, the BGP route table (RIB) keeps increasing, and this subsequently results in severe FIB inflation at BGP routers. What if we only load a small portion of the ...
متن کاملPractical and Near-Optimal FIB Aggregation using SMALTA
IP Routers use sophisticated forwarding table (FIB) lookup algorithms that minimize lookup time, storage, and update time. This paper presents SMALTA, a practical, near-optimal FIB aggregation scheme that shrinks forwarding table size without modifying routing semantics or the external behavior of routers, and without requiring changes to FIB lookup algorithms and associated hardware and softwa...
متن کاملSNIPS: A Software-Defined Approach for Scaling Intrusion Prevention Systems via Offloading
Growing traffic volumes and the increasing complexity of attacks pose a constant scaling challenge for network intrusion prevention systems (NIPS). In this respect, offloading NIPS processing to compute clusters offers an immediately deployable alternative to expensive hardware upgrades. In practice, however, NIPS offloading is challenging on three fronts in contrast to passive network security...
