    摘要： A SoftRouter architecture deconstructs routers by separating the control entities of a router from its forwarding components, enabling dynamic binding between them. In the SoftRouter architecture, control plane functions are aggregated and implemented on a few smart servers which control forwarding elements that are multiple network hops away. A dynamic binding protocol performs network-wide control plane failovers. Network stability is improved by aggregating and remotely hosting routing protocols, such as OSPF and BGP. This results in faster convergence, lower protocol messages processed, and fewer route changes following a failure. The SoftRouter architecture includes a few smart control entities that manage a large number of forwarding elements to provide greater support for network-wide control. In the SoftRouter architecture, routing protocols operate remotely at a control element and control one or more forwarding elements by downloading the forwarding tables, etc. into the forwarding elements. Intra-domain routing and inter-domain routing are also included.

    摘要： A seamless transport endpoint mobility (STEM) architecture migrates a transport connection endpoint from an old IP address to a new IP address without loss of the session. The migration process is negotiated between two endpoints themselves. Transport endpoint mobility includes communication between two STEM daemons, one STEM daemon in each endpoint, which dynamically updates kernel data structures (e.g., elements of a 5-tuple associated with a TCP/IP application) associated with the session. Migration is transparent to the application using the underlying transport connection for data transfer.
