Realms in GINA

Object names and Ids are defined within a realm A realm is a logical grouping of objects under an administrative domain The Administrative domain may be based on Trust Relationships A realm represents an organization


Realm managers set policies for communications Realm members can share services Objects are generally members of multiple realms Realm Boundaries:

Neither
the server nor the clients have any control over the “middle mile” Fat File Paradox:

it is the length of the pipe rather than its width that determines how fast a large file can travel through it
Next generation P2P
The self-organizing and self-healing properties of P2P networks have the potential to become the predominant content distribution mechanism of the future Internet. Bandwidth provision (Asymmetric) Dynamic sharing Tussle of interests between P2P networks and ISPs

Introduction

Internet 1.0 (1969 – 1989) – Research project



RFC1 is dated April 1969. ARPA project started a few years earlier. IP, TCP, UDP Mostly researchers Industry was busy with proprietary protocols: SNA, DECnet,AppleTalk, XNS Security RFC1108 in 1989 NSFnet became commercial Inter-domain routing: BGP (Policy-based) Address Shortage IPv6 Congestion Control, Quality of Service,…

Content-Centric Networks

IP cares about “Where”: forward packets from A to B Users care about “What”: Movie X Replace “packets” with “Data Objects” or “Interests” (requests) Replace “Addresses” with “Names of Objects”
