What’s P2P?

September 16, 2005

There are many definitions to peer to peer technology. The following is some characteristics of P2P:

Everything except the client/server model
可以认为除了C/S架构之外的所有东西都是P2P架构的,实际上C/S才是特殊的,而P2P则是普遍的。
Network of nodes with equivalent capabilities/responsibilities (symmetrical)
P2P网络中的节点具有对等的能力和责任,是对称的。
Nodes are both Servers and clients called “Servents”
P2P网络中的节点同时即是服务器,也是客户端。

At wikipedia, Peer-to-Peer stands for:

A peer-to-peer (or P2P) computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes. Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.


Security management deeply involved into enterprise infrastructure management

September 16, 2005

运营商(也包括广电运营商和数据中心)总是不断地寻求新的技术手段以最大限度地挖掘网络潜力、提高每用户营收、提高单位带宽的营收、寻找新的利润增长 点、开发新的业务组合、降低客户流失。这些新的措施包括控制P2P业务流、对家庭和SOHO用户提供�级化(差异化)的服务以替代当前施行中的大包月资 费、 对商业客户提供服务质量保障(SLA)、提升自身在未来话音、视频和数据三重业务(Triple Play)市场的竞争力。

所以,对网络传送的IP分组数据除了保证其可达性、延时、安全性之外,对其有效的监视、分类和控制是运营商能够立足于3G/NGN年代的基础能力。

Security management is having a much wide meaning to those telecommunication carriers, bandwidth mangement, performance management, traffic shaping, identity and accounting…. I am fraid that you can not find out what’s not security related.
