Forwarding Label support in CCN Protocol
暂无分享,去创建一个
The objective of this proposal is to enable application identifier
(AI) and network identifier (NI) split in the CCN protocol that has
several applications such as towards Interest routing optimization,
mobility, conversational session support, handling indirections in
manifests, and routing scalability. We enable this through the notion
of forwarding label object (FLO), which is an optional hop-by- hop
payload in the Interest message with a topological name which
identifies a network domain, router or a host. FLO can be inserted by
the end user applications or by the network. FLO is processed by the
network resulting in either terminating it or swapping it with a new
FLO based on the network service context. Furthermore, depending on
the application and trust context, a FLO can be subjected to policy
based actions by the forwarders such as invoking security verification
or enabling other FLO management actions.
