Intelligent services are provided in a storage network using intelligent service modules that can be cabled to a switch external to the switch chassis and yet be managed as part of the switchs logical domain. Data and management communications between the intelligent service module and the core switch are provided through a soft-backplane implemented using in-band communications through cabling attached between the switch and the intelligent service module rather than through a hardwired backplane within the chassis. Management communications from management software is directed to the switch, which handles the management functions relating to the intelligent service module or forwards the management requests to the intelligent service module for processing.


A network element having a Non-Access Stratum (NAS) Node Selection Function for discriminating information in order to determine which core network node a signaling message should be sent comprising: a network interface unit configured to interact with a packet network system; a processor with a memory associated with the network interface unit and adapted to: receive the signaling message from an eNB at a selection function; extract header information from Stream Control Transport Protocol (SCTP) of the signaling message; communicate with a database having a persistent application map to determine if there is an association between the header information and a core network entity; if there is an association, forward the signaling message to a selected core network entity; and determine at the selected core network entity which one of a plurality of core network nodes within a core network pool to route the message based on availability of the plurality of core network nodes.

One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a forwarding domain apparatus and a forwarding apparatus. The forwarding domain apparatus maintains a mapping between a first virtual local area network (VLAN) identifier and a first global VLAN identifier in a local storage device. The global VLAN identifier represents a layer-2 forwarding domain in the network and is distinct from a customer VLAN or a service-provider VLAN. The mapping is independent of a type of the VLAN identifier. During operation, the forwarding apparatus encapsulates a first packet belonging to the first VLAN in a network encapsulation header. The encapsulated packet is forwardable in the network based on the network encapsulation header. The forwarding apparatus includes the first global VLAN identifier in the network encapsulation header of the first packet.

Techniques for transforming a legacy network into a Software Defined Networking (SDN) enabled network are provided. In one embodiment, a route server can receive one or more routing protocol packets originating from a network device, where the one or more routing protocol packets are forwarded to the route server via a cross connect configured on a network router. The route server can further establish a routing protocol session between the route server and the network device based on the one or more routing protocol packets, and can add a routing entry to a local routing table. Upon adding the routing entry, the route server can automatically invoke an application programming interface (API) for transmitting the routing entry to a Software Defined Networking (SDN) controller.

One embodiment of the present invention provides a switch that is a member of a fabric switch. The switch includes a keepalive response module that identifies a keepalive response packet that does not correspond to any keepalive packet previously transmitted by the switch. The switch also includes a switch identifier extraction module that extracts a switch identifier from a payload of the keepalive response packet, where the switch identifier corresponds to another member switch in the fabric switch. The switch further includes a forwarding module that constructs a packet that includes the payload and is destined to the other member switch.
