Traffic Engineering (TE) is one of the keys for improving packet forwarding in\ the Internet. It allows IP network operators to finely tune their forwarding\ paths according to various customer needs. One of the most popular tool\ available today for optimizing the use of networking resources is MPLS. On the\ one hand, operators may use MPLS and label distribution mechanisms such as RSVP-TE\ in conjunction with BGP to define multiple transit paths (for a given edge pair)
verifying different constraints on their network. On the other hand, when\ operators simply enable LDP for distributing MPLS labels in order to improve the\ scalability of their network, another kind of path diversity may appear thanks\ to the ECMP feature of IGP routing.

In this paper, using an MPLS labels analysis, we demonstrate that it is possible\ to better understand the transit path diversity deployed within a given ISP.\ More specifically, we introduce the Label Pattern Recognition (LPR) algorithm, a\ method for analyzing traceroute data including MPLS information. LPR reveals\ the actual usage of MPLS according to the inferred label distribution protocol and\ is able to make the distinction between ECMP and TE multi-path forwarding.\ Based on an extensive and longitudinal traceroute dataset obtained from CAIDA,
we apply LPR and find that each ISP behavior is really specific in regard to its\ MPLS usage. In particular, we are able to observe independently for each ISP\ the MPLS path diversity and usage, and its evolution over time.\ Globally speaking, the main outcomes of our study are that (i) the usage of\ MPLS has been increasing over the the last five years with basic encapsulation\ being predominant, (ii) path diversity is mainly provided thanks to ECMP and\ LDP, and, (iii), TE using MPLS is as common as MPLS without path diversity.

Transport Layer Security (TLS), is the de facto protocol supporting secure HTTP (HTTPS), and is being discussed as the default transport protocol for HTTP2.0. It has seen wide adoption and is currently carrying a significant fraction of the overall HTTP traffic (Facebook, Google and Twitter use it by default). However, TLS makes the fundamental assumption that all functionality resides solely at the endpoints, and is thus unable to utilize the many in-network services that optimize network resource usage, improve user experience, and protect clients and servers from security threats. Re-introducing such in-network functionality into secure TLS sessions today is done through hacks, in many cases weakening overall security.

In this paper we introduce multi-context TLS (mcTLS) which enhances TLS by allowing middleboxes to be fully supported participants in TLS sessions. mcTLS breaks the "all-or-nothing" security model by allowing endpoints and content providers to explicitly introduce middleboxes in secure end-to-end sessions, while deciding whether they should have read or write access, and to which specific parts of the content. mcTLS enables transparency and control for both clients and servers.

We evaluate a prototype mcTLS implementation in both controlled and "live" experiments, showing that the benefits offered have minimal overhead.More importantly, we show that mcTLS can be incrementally deployed and requires small changes to clients, servers, and middleboxes, for a large number of use cases.

We report an experimental investigation on the measurement of the available bandwidth for the users in Gigabit Passive Optical Networks (GPON) and the limitations caused by the Internet protocols, and TCP in particular. We point out that the huge capacity offered by the GPON highlights the enormous differences that can be showed among the available and actually exploitable bandwidth. In fact, while the physical layer capacity can reach value of 100 Mb/s and more, the bandwidth at disposal of the user (i.e. either throughput at transport layer or goodput at application layer) can be much lower when applications and services based on TCP protocol are considered. In the context of Service Level Agreements (SLA) verification, we show how to simultaneously measure throughput and line capacity by offering a method to verify multilayer SLA. We also show how it is possible to better to exploit the physical layer capacity by adopting multiple TCP connections to avoid the bottleneck of a single connection.

The popularity of web-based services and multimedia applications like YouTube, Google Web Search, Facebook, and a bewildering range of Internet applications has taken HTTP back to the pole position on end-user traffic consumption. Today{\textquoteright}s Internet users exchange most of their content via HTTP. In this paper we address the problem of on-line HTTP traffic classification from network measurements. Building on the results provided by HTTPTag, a flexible system for on-line HTTP classification, we present and explore Mini-IPC. Mini-IPC is a minimalist approach for classifying HTTP flows using only the IP addresses of the servers hosting the corresponding content. Using one full week of HTTP traffic traces collected at the mobile broadband network of a major European ISP, we investigate to which extent the most popular HTTP-based services are hosted by well-defined sets of IP addresses, and evaluate the performance of Mini-IPC to classify these services using IPs only.

Recently, a negative interplay has been shown to
arise when scheduling/AQM techniques and low-priority conges-
tion control protocols are used together: namely, AQM resets
the relative level of priority among congestion control protocols.
This work explores this issue by (i) studying a fluid model that
describes system dynamics of heterogeneous congestion control
protocols competing on a bottleneck link governed by AQM and
(ii) proposing a system level solution able to reinstate priorities
among protocols.
