A method for configuring a communication path comprises: receiving a first frame requesting to configure a communication path through which a stream is transmitted; configuring a table of the first communication node based on information included in the first frame, when a second frame having a same stream identifier as a stream identifier of the first frame is not received; increasing a hop count of the first frame; and transmitting the first frame including the increased hop count.

In an approach for achieving resilience and load balancing control over layer 2 gateways in a cluster, a processor forms a cluster, wherein the cluster includes one or more layer 2 gateways. A processor registers endpoints for a tenant system attached to a virtual network through a bridge network to add to an endpoint database used to associate a destination MAC address with the cluster. A processor distributes flow of data.

In an example, a system and method for data plane integration is described. Aspects of the embodiments are directed to a service application connected to a switch of a network fabric and a method of data plane integration performed at a service appliance, the service appliance providing firewall functionality. The service appliance can receive a data packet from a network location; determine a flow owner of the data packet based on a hashing table; and transmit the data packet based on the determined flow owner of the data packet.

Techniques for routing network traffic in a storage processor involve providing per-IP routing tables for each IP address of a virtual server and a per-server routing table. These per-IP and per-server routing tables specify its own interface(s) with external network(s). The storage processor assigns each outbound protocol data unit (PDU), generated by a particular virtual server, to either a per-IP routing table or a per-server routing table provided for that virtual server. The assignment of the routing table is based on source IP address or a connection mark associated with an outbound PDU. The per-IP or per-server routing table(s) identifies an interface through which the packet is routed to the destination IP address.

Examples of the present disclosure may provide a migration method. An emigration TR may receive a map notify message carrying a mapping relationship between an EID of the host and an RLOC of an immigration TR. The emigration TR may make a determination as to whether the RLOC of the immigration TR is same as an RLOC of the emigration TR. The emigration TR may search for an RLOC of a remote TR if the RLOC of the immigration TR is different from the RLOC of the emigration TR. The emigration TR may send an SMR message to the remote TR using the RLOC of the remote TR.

A process is implemented by a network device for enabling the provisioning of explicit trees in a network by reporting link aggregation group (LAG) configuration information to a path computation element (PCE). The network device implements a LAG module and an intermediate system-intermediate system (IS-IS) module that includes an IS-IS path control and reservation module (ISIS-PCR). The process includes reporting LAG configuration by the LAG module to the IS-IS module within the network device, sending a link state protocol data unit (PDU) (LSP) with the LAG configuration in a LAG sub type length value (TLV) by the ISIS-PCR, receiving, by the IS-IS module, an explicit tree that specifies at least one virtual local area network (VLAN) identifier (VID) to an aggregation link of the LAG assignment, and translating, by the ISIS-PCR module, the explicit tree into a LAG configuration, the LAG configuration specifying a conversation to aggregation link assignment.

A system for creating a session entry and forwarding an IP packet includes memories that store session and session template tables, and first and second processors in communication with the memories. When the first processor receives the IP packet, it determines whether the session table includes a session entry corresponding to the IP packet. If the session table does not include the session entry, the first processor determines whether the session template table includes a session template entry corresponding to the IP packet. The first processor generates the session entry using the session template entry and the IP packet. If the session template table does not include the session template entry, the first processor forwards the IP packet to the second processor, which generates the session template entry and the session entry.

An example of a distributed system partition can include a method for client service in a distributed switch. The method can include maintaining local and global connection state information between a primary and a secondary controlling fibre channel (FC) over Ethernet (FCoE) Forwarders (FCFs) or FC forwarder in a distributed switch. A partition in the distributed switch can be detected and service to subtended clients of the distributed switch can continued using local state information.

A router of a content centric network (CCN) can forward messages using anonymous identifiers. The router can receive an Interest via a first interface, and determines a first anonymous identifier (AID) that identifies a name-independent path to the Interest's source via the router. The router can identify a second interface for forwarding the Interest to a next-hop neighbor via CCN, and performs a bijective function on the first AID to obtain a second AID that is to be used by the next-hop neighbor to return a corresponding data packet to the router. The router updates the Interest to include the second AID, and forwards the Interest via the second interface toward the next-hop neighbor. When the router receives the data packet, the router performs a lookup operation in an anonymous routing table (ART), based on the AID, to determine an interface for forwarding the data packet toward the Interest's source.

A method for controlling a plurality of network interfaces of an electronic device includes: providing at least one table comprising information associated with a plurality of routing costs, wherein the routing costs correspond to at least paths between each of the network interfaces of the electronic device and the other electronic devices; and referring to the at least one table to select a specific network interface to transmit/receive data, and to disable at least one of the unused network interfaces.
