14、2. Design GoalsWe aim at designing a future Internet architecture that satisfies the following design goals: Being information centric: While the current Internet was designed centered on hosts, its current majority usage is data retrieval. Accordingly, there is an increasing consensus that the futu
15、re Internet should be information-centric. That is, content should be addressed independent of its hosted location. Efficient support for mobility: With the rapid increase in the number of mobile devices, the future Internet architecture should efficiently support mobility.Until March 2013, the numb
16、er of mobile users in China is 1.146 billion; 71.34% of them have access to the Internet.Cisco predicted that: “traffic from wireless devices will exceeds traffic wired devices by 2014.CoLoR: An Information-Centric Future Internet Architecture for Innovation8 Beijing Jiaotong University2. Design Goa
17、ls Efficient support for multi-homing: In multi-homing, a host (or network) is simultaneously attached to multiple networks. While the current Internet is cumbersome to support multi-homing since it causes serious routing scalability issue, the future internet architecture is expected to efficient s
18、upport multi-homing. Encouraging innovation: The future internet architecture should allow each network to use its preferred network architecture and routing mechanism so that different network technologies can be simultaneously deployed and contest, thus encouraging innovation. Enhanced security: T
19、he current Internet employs a default-on model and any host is able to send packets to a remote host, which makes the current Internet fragile to distributed denial-of-service attacks. Therefore, the future Internet should offer receivers the ability to control incoming traffic, especially to refuse
20、 unwanted traffic.CoLoR: An Information-Centric Future Internet Architecture for Innovation9 Beijing Jiaotong University2. Design Goals Enhanced scalability: The future Internet should provide better routing scalability over the current Internet. The routing table size should be significantly less t
21、han that in the current Internet. Ease of traffic matrix estimation: It is difficult to estimate traffic matrices in the current Internet. However, since traffic matrices are critical inputs to many aspects of network management such as traffic engineering and network provisioning, the future Intern
22、et should makes it easy to precisely estimate traffic matrices in real time. Deployability: Although we aim at a clean-slate design, the future Internet architecture should be deployed without incurring significant cost.CoLoR: An Information-Centric Future Internet Architecture for Innovation10 Beij
23、ing Jiaotong University3. Design detailsBasic ideas:I. Using four namespaces:Service identifiers (SIDs): used to name contents. They are flat, self-certifying.Node identifiers (NIDs): used to identify the identity of network nodes. They are flat, self-certifying and 128 bits long.Intra-domain routin
24、g locators: used for intra-domain routing. Every domain can choose its preferred intra-domain routing architecture and routing locators.Path identifiers (PIDs): used for inter-domain routing. Two domains can negotiate a set of PIDs, as long as the PIDs are unique in each domain. PIDs are not advertised throughout the Internet, but are local to the two domains.
