The access edge node verifies whether a service agent, corresponding to the service provider identified in a received service request, exists. If so, the user domain is added to the VLAN corresponding to the requested service provider by creating a service binding at the access edge node. An access node providing access to the access domain to the user domain is informed of the service binding. Data traffic between the user domain and the identified service provider is aggregated over the access domain according to the created service binding.

Distributed finite state machine

A method, a router and a switching element card for providing a rate limiting mechanism in the router. Upon reception of a packet stream from a forwarding element card of the router at a first rate, it is determined that the packet stream is to be forwarded to a further card of the router.

Handling ip datagram fragments

Problems caused by Internet Protocol datagram fragmentation are solved by creating a session context for the datagram fragments without actually reassembling the datagram from its fragments. The session context enables treatment of the datagram without actually reassembling it. Processing fragments can be followed by forwarding the processed fragments to another node that can further fragment the IP datagram.
