YouTube Traffic Dynamics and Its Interplay with a Tier-1 ISP: An ISP Perspective
"... In this paper we conduct an extensive and in-depth study of traffic exchanged between YouTube data centers and its users, as seen from the perspective of a tier-1 ISP in Spring 2008 after YouTube was acquired by Google but before Google did any major restructuring of YouTube. Using flow-level data c ..."

From Traffic Matrix to Routing Matrix: PoP Level Traffic Characteristics for a Tier-1 ISP
"... Traffic matrices play a pivotal role in the management of an ISP’s network such as various levels of traffic engineering and capacity planning. However, it is unclear how the interaction between the internal traffic routing policies chosen by the ISPs and large-scale content providers, and the ongoi ..."

, and the ongoing trend of “cloud-computing ” affect the traffic matrices. In this paper, we use network data collected by a Tier-1 ISP to understand the characteristics of a PoP-level traffic matrix. We also shed light on the role of “routing matrix ” in shaping the characteristics of the traffic matrix. Two
Performance Modeling on the interaction of ISPs

In particular, we consider a simplified two-level hierarchical model wherein there are a single tier-1 ISP and ¢¤£¦ ¥ ..."

Understanding BGP Session Failures in a Large ISP
"... Abstract—The current global Internet routing frequently suffers from cascading routing changes and slow routing convergence. Such instability can significantly affect the performance of real-time Internet applications such as VoIP, multimedia conferencing and online gaming. One major cause of routin ..."

of routing instability is the failure of BGP peering sessions, but there has been little understanding of the factors that contribute to the failures of operational BGP sessions. In this paper, we present a systematic study on the failures of a few hundred BGP sessions using data collected in a tier-1 ISP
Seamless Access Router Upgrades through IP/Optical Integration
"... Abstract: We describe RFC, a new capability that minimizes customer outages during software and hardware upgrades in ISP networks. RFC is being used by a large Tier-1 ISP to upgrade access routers supporting thousands of customers. OCIS codes: (060.4250) Networks; (060.4510) Optical communications 1 ..."

The Flattening Internet Topology: Natural Evolution, Unsightly Barnacles or Contrived Collapse?
"... Abstract. In this paper we collect and analyze traceroute measurements 1 to show that large content providers (e.g., Google, Microsoft, Yahoo!) are deploying their own wide-area networks, bringing their networks closer to users, and bypassing Tier-1 ISPs on many paths. This trend, should it continue ..."

Demystifying configuration challenges and trade-offs in network-based isp services
- In Proc. SIGCOMM
, 2011
"... ISPs are increasingly offering a variety of network-based services such as VPN, VPLS, VoIP, Virtual-Wire and DDoS protection. Although both enterprise and residential networks are rapidly adopting these services, there is little systematic work on the design challenges and trade-offs ISPs face in pr ..."

The goal of our paper is to understand the complexity underlying the layer-3 design of services and to highlight potential factors that hinder their introduction, evolution and management. Using daily snapshots of configuration and device metadata collected from a tier-1 ISP, we examine
Packet classification in large ISPs: Design and evaluation of decision tree classifiers
- In ACM SIGMETRICS
, 2005
"... Packet classification, although extensively studied, is an evolving problem. Growing and changing needs necessitate the use of larger filters with more complex rules. The increased complexity and size pose implementation challenges on current hardware solutions and drive the development of software ..."

classifiers, in particular, decisiontree based classifiers. Important performance measures for these classifiers are time and memory due to required high throughput and use of limited fast memory. We analyze Tier 1 ISP data that includes filters and corresponding traffic from over a hundred edge routers
Packet Classification for Core Routers: Is there an alternative to CAMs
, 2003
"... A classifier consists of a set of rules for classifying packets based on header fields. Because core routers can have fairly large (e.g., 2000 rule) database and must use limited SRAM to meet OC-768 speeds, the best existing classification algorithms (RFC, HiCuts, ABV) are precluded because of the l ..."

-case speed scales well with database size while using a minimal amount of memory. Our evaluation is based on real databases used by Tier 1 ISPs, and synthetic databases. EGT-PC is based on a observation that we found holds for all the Tier 1 databases we studied: regardless of database size, any packet
