Description: 流分类算法中的一种，Scalable Packet Classification 非常有参考价值-Packet classification is important for applications such as
firewalls, intrusion detection, and differentiated services. Existing
algorithms for packet classification reported in the literature
scale poorly in either time or space as filter databases
grow in size. Hardware solutions such as TCAMs do not
scale to large classifiers. However, even for large classifiers
(say 100,000 rules), any packet is likely to match a few (say
10) rules. Our paper seeks to exploit this observation to
produce a scalable packet classification scheme called Aggregated
Bit Vector (ABV). Our paper takes the bit vector
search algorithm (BV) described in [11] (which takes linear
time) and adds two new ideas, recursive aggregation of
bit maps and filter rearrangement, to create ABV (which
can take logarithmic time for many databases). We show
that ABV outperforms BV by an order of magnitude using
simulations on both industrial firewall databases and synthetically
generated databases. Platform: |

Description: 巴黎地铁系统在网络上的应用:
随着互连网的发展，单一的计费方式既不利于网络服务商的利益最大化，也不能满足一些网络的高级应用的需要。
把网络进行划分，各个分区相同或不同的服务能力，但是它们有不相的价格。因此相对价格较高的服务分区由于选择的人比较少而负载轻，因而有较少的时延。由于不同服务有不同的QoS要求，如网络视频，电话需要较高的带宽要求，所以必需选用价格较高的网络分区才能满足需要，而像下载，网页浏览对QoS的要求相对较低，因此可以选用价格较低的网络分区。其主要原理把是把网络时延作为网络一种内在的价值。其应用的基础在于其本身的简单性，易于实现。
-Abstract—Paris Metro Pricing (PMP) is a simple multi-class
fl at-rate pricing scheme already practiced by transport systems,
specifi cally by the Paris Metro at one time. The name is coined
after Andrew Odlyzko proposed it for the Internet as a simple
way to provide differentiated services. Subsequently, there were
several analytical studies of this promising idea. The central issue
of these studies is whether PMP is viable, namely, whether it
will produce more profi t for the service provider, or whether it
will achieve more social welfare. The previous studies considered
similar models, but arrived at different conclusions. In this
paper, we point out that the key is how the users react to
the congestion externality of the underlying system. We derive
suffi cient conditions of congestion functions that can guarantee
the viability of PMP, and provide the relevant physical meanings
of these conditions. Platform: |

Description: 质量服务（QoS）是一种常用和滥用的术语有多种含义。在
这本书中，QoS是指综合服务（集成服务）和区分服务（DiffServ的）。
虽然这两种机制大大不同，集成服务和DiffServ的基本目标是实现

In this book, QoS refers to the integrated services (integration services) and Differentiated Services (DiffServ' s). While these two very different mechanisms, integration services and DiffServ basic goal is to achieve the bandwidth required for a specific application and delay Platform: |

Description: This paper presents one of the features of DS
(Differentiated Services) architecture, namely the queuing or
congestion management. Packets can be placed into separate
buffer queues, on the basis of the DS value. Several forwarding
policies can be used to favor high priority packets in different
ways. The major reason for queuing is that the router must hold
the packet in its memory while the outgoing interface is busy with
sending another packet. Our main goal is to compare the
performance of the following queuing mechanisms: FIFO (First-
In First-Out), CQ (Custom Queuing), PQ (Priority Queuing),
WFQ (Weighted Fair Queuing), CBWFQ (Class Based Weighted
Fair Queuing) and LLQ (Low Latency Queuing). Platform: |

Description: The new emerging QoS architectures are motivated by the desire to improve the
overall performance of an IP network. Differentiated Services (Diffserv) define a model for
implementing scalable differentiation of QoS in the Internet. Multiprotocol Label
Switching (MPLS) is a fast label-based switching technique that offers new QoS
capabilities for large scale IP networks. When an MPLS network supports DiffServ, traffic
flows can receive class-based network treatment that provides bases for QoS guarantees.
The objective of this work is to study the influence of the QoS mechanism via
DiffServ-MPLS on network parameters such as jitter, delay and throughput. The
comprehensive study showed general improvement in the throughput, jitter and delay
particularly of voice and video transmission when using DiffServ-aware MPLS network as
compared to pure IP only or MPLS only. Platform: |
