{While dense wavelength division multiplexing equipment has been deployed in networks of major telecommunications carriers for over a decade, the capabilities of its networking and associated network control and management have not caught up to those of digital cross-connect systems and packet-switched counterparts in higher layer networks. We shed light on this situation by examining the current structure of the optical layer, its relationship to other network technology layers, and current network management and control implementations. We provide additional insight by explaining how a combination of business and technical perspectives has driven evolution of the optical layer. We conclude by exploring activities to close this gap in the future.}

{The security of the networking infrastructure (e.g., routers and switches) in large scale enterprise or Internet service provider (ISP) networks is mainly achieved through mechanisms such as access control lists (ACLs) at the edge of the network and deployment of centralized AAA (authentication, authorization and accounting) systems governing all access to network devices. However, a misconfigured edge router or a compromised user account may put the entire network at risk. In this paper, we propose enhancing existing security measures with an intrusion detection system overseeing all network management activities. We analyze device access logs collected via the AAA system, particularly TACACS+, in a global tier-1 ISP network and extract features that can be used to distinguish normal operational activities from rogue/anomalous ones. Based on our analyses, we develop a real-time intrusion detection system that constructs normal behavior models with respect to device access patterns and the configuration and control activities of individual accounts from their long-term historical logs and alerts in real-time when usage deviates from the models. Our evaluation shows that this system effectively identifies potential intrusions and misuses with an acceptable level of false alarms.

{Service quality in operational IP networks can be impacted due to planned or unplanned maintenance. During any maintenance activity, the responsibility of the operations team is to complete the work order and perform a check-up to ensure there are no unexpected service disruptions. Once the maintenance is complete, it is crucial to continuously monitor the network and look for any performance impacts. What operations lack today are effective tools to rapidly detect maintenance induced performance changes. The large scale and heterogeneity of network elements and performance metrics makes the problem extremely challenging.
In this paper, we present PRISM, a new tool for detecting maintenance induced performance changes in a timely fashion. PRISM uses association between maintenance and the network elements to identify performance metrics for time-series analysis. It uses a new Multiscale Robust Local Subspace algorithm (MRLS) to accurately identify changes in performance even when the baseline is contaminated. We systematically evaluate PRISM using data collected at four large operational networks: a tier-1 backbone, VoIP, IPTV and 3G cellular and show that it achieves good accuracy. We also demonstrate the effectiveness of PRISM in real operational environments through interesting case study findings.}

{In large-scale IPTV systems, it is essential to
maintain high service quality while providing a wider variety
of service features than typical traditional TV. Thus
service quality assessment systems are of paramount importance
as they monitor the user-perceived service quality and
alert when issues occurs. For IPTV systems, however, there
is no simple metric to represent user-perceived service quality
and Quality of Experience (QoE).Moreover, there is only
limited user feedback, often in the form of noisy and delayed
customer complaints. Therefore, we aim to approximate the
QoE through a selected set of performance indicators in a
proactive (i.e., detect issues before customers complain) and
scalable fashion.
In this paper, we present service quality assessment framework,
Q-score, which accurately learns a small set of performance
indicators most relevant to user-perceived service
quality, and proactively infers service quality in a single score.
We evaluate Q-score using network data collected from a
commercial IPTV service provider and show that Q-score is
able to predict 60% of service problems that are complained
by customerswith 0.1%of false positives. ThroughQ-score,
we have (i) gained insight into various types of service problems
causing user dissatisfaction includingwhy users tend to
react promptly to sound issues while late to video issues; (ii)
identified and quantified the opportunity to proactively detect
the service quality degradation of individual customers
before severe performance impact occurs; and (iii) observed
possibility to adaptively allocate customer care workforce to
potentially troubling service areas.}

{Cloud service providers use replication across geographically distributed data centers to improve end-to-end performance as well as to offer high reliability under failures. Content replication often involves the transfer of huge data sets over the wide area network and demands high backbone transport capacity. In this paper, we discuss how a Globally Reconfigurable Intelligent Photonic Network (GRIPhoN) between data centers could improve operational flexibility for cloud service providers. The proposed GRIPhoN architecture is an extension of earlier work [34] and can provide a bandwidth-on-demand service ranging from low data rates (e.g., 1 Gbps) to high data rates (e.g., 10-40 Gbps). The inter-data center communication network which is currently statically provisioned could be dynamically configured based on demand. Today's backbone optical networks can take several weeks to provision a customer's private line connection. GRIPhoN would enable cloud operators to dynamically set up and tear down their connections (sub-wavelength or wavelength rates) within a few minutes. GRIPhoN also offers cost-effective restoration capabilities at wavelength rates and automated bridge-and-roll of private line connections to minimize the impact of planned maintenance activities.}

{Abstract�Recent trends in the networked services industry
(e.g., CDN, VPN, VoIP, IPTV) see Internet Service Providers
(ISPs) leveraging their existing network connectivity to provide
an end-to-end solution. Consequently, new opportunities are
available to monitor and improve the end-to-end service quality
by leveraging the information from inside the network. We
propose a new approach to detect and localize end-to-end
service quality issues in such ISP-managed networked services by
utilizing traffic data passively monitored at the ISP side, the ISP
network topology, routing tables and geographic information.
This paper presents the design of a generic service quality
monitoring system �Argus�. Argus has been successfully deployed
in a tier-1 ISP to monitor millions of users of its CDN service
and assist operators to detect and localize end-to-end service
quality issues.This operational experience demonstrates that
Argus is effective in accurate, quick detection and localization of
important service quality issues.}

{Recent advances in residential broadband access
technology have led to a wave of commercial IPTV deployment.
As IPTV services are rolled out at scale, it is essential
for IPTV systems to maintain ultra-high reliability
and performance. A major issue that disrupts IPTV service
is the crash of the set-top box (STB) software, which directly
resides inside the consumer�s home network and provides
the essential interface to both the user and the network to
deliver rich contents that go well beyond traditional TV. To
understand the potential causes of STB crashes, we perform
in-depth statistical analysis on the relationship among STB
crashes, video stream contents, and user activities using logs
collected from a large commercial IPTV system. Our initial
results suggest that (i) impaired video streams may cause
STB to crash, and (ii) continuous usage of STB may gradually
degrade the STB health over time.}

{Social media sites like twitter continue to grow at a fast pace.
People of all generations use social media to exchange messages
and share experiences of their life in a timely fashion.
Most of these sites make their data available. An intriguing
question is can we exploit this real-time and giant data-flow
to improve business in a measurable way. In this paper, we
are particularly interested in tweets (twitter messages) that
are relevant to mobile network performance. We compare
tweets with traditional source of user experience, i.e. customer
care tickets, and correlate both of them with network
incident reports. From our study, we have the following observations.
First, twitter users and users who call customer
service tend to report different types of performance issues.
Second, users on twitter are more accurate and faster to report
network problems that impact user experiences. Third,
tweets can show some short term performance impairments,
which are not recorded in incidents reports. These observations
prove that twitter a complimentary source for monitoring
network performance and their impact on user experiences.}

{As IP networks have become the mainstay of an increasingly diverse set of applications ranging from Internet games and streaming videos, to e-commerce and online banking, and even to mission-critical 911 over VoIP, best effort service is no longer acceptable. This requires a transformation in network management, changing its focus from detecting and replacing individual faulty network elements, such as routers and line cards, to managing the service quality as a whole for end-users.
In this paper we describe the design and development of a Generic Root Cause Analysis platform (G-RCA) for service quality management (SQM) in large IP networks. G-RCA contains a comprehensive service dependency model that includes network topological and cross-layer relationships, protocol interactions, and routing and control plane dependencies. G-RCA abstracts the RCA process
into signature identification for symptom and diagnostic events, temporal and
spatial event correlation, and reasoning and inference logic. G-RCA provides a simple yet flexible rule specification language that allows operators to quickly customize G-RCA into different RCA tools as new problems need to be investigated and understood. G-RCA is also integrated with the data trending,
manual data exploration, and statistical correlation mining capabilities that are tailored for SQM. G-RCA has proven to be a highly effective SQM platform in several different applications and we present results regarding BGP flaps, PIM flaps in Multicast VPN service, and end-to-end throughput drop in CDN service.}
