Big Data-backed video distribution in the telecom cloud
Telecom operators are starting the deployment of Content Delivery Networks (CDN) to better control and manage video contents injected into the network. Cache nodes placed close to end users can manage contents and adapt them to users' devices, while ...
Novel adaptive virtual network embedding algorithm for Cloud's private backbone network
In this paper, we study the adaptive virtual network embedding problem within Cloud's backbone. The main idea is to take profit from the unused bandwidth but allocated to virtual networks. Consequently, the acceptance rate of new clients will be ...
Virtual Network Embedding for telco-grade network protection and service availability
The decoupling of software from hardware by means of virtualization presents us with a unique opportunity to perform on-the-fly network deployment and reconfiguration. Virtual Machines could be instantiated and virtual links can connect these machines ...
Towards automatic protocol field inference
Security tools have evolved dramatically in the recent years to combat the increasingly complex nature of attacks. However, these tools need to be configured by experts that understand network protocols thoroughly to be effective. In this paper, we ...
Pragmatic router FIB caching
Several recent studies have shown that router FIB caching offers excellent hit rates with cache sizes that are an order of magnitude smaller than the original forwarding table. However, hit rate alone is not sufficient - other performance metrics such ...
Queue-aware uplink scheduling with stochastic guarantees
Adaptive resource allocation arises naturally as a technique to optimize resource utilization in communication networks with scarce resources under dynamic conditions. One prominent example is cellular communication where service providers seek to ...
Lightweight capacity measurements for mobile networks
Packet dispersion technique tuned for mobile networks.Lightweight and passive: its input is only already existing traffic.Is able to provide accurate results with a fraction of the exchanged packets.Is not affected by the scheduling process of eNodeBs ...
Energy-aware opportunistic mobile data offloading under full and limited cooperation
Opportunistic networking (a.k.a. device-to-device communication) is considered a feasible means for offloading mobile data traffic. Since mobile nodes are battery-powered, opportunistic networks must be expected to satisfy the user demand without ...
