The network controller assigns flow data which is necessary for relay and issues a flow transfer instruction to a switch. The assigned flow data is notified to the relay unit and the relay unit sets a communication flow to a destination terminal by using the specified flow data, and relays the data to the destination terminal from the transmission source terminal. | 2012-10-18 |
20120263187 | Two-Layer Switch Apparatus Avoiding First Layer Inter-Switch Traffic In Steering Packets Through The Apparatus - Link-level data communications implemented in switching apparatus comprising modular switches disposed within a modular computer cabinet that includes modular computer systems; the switching apparatus configured as two layers of switches, the first layer switches coupled to one another for communications by inter-switch links, each second layer switch coupled for communications to the modular computer systems; all the switches stacked by a stacking protocol that shares administrative configuration information among the switches through the inter-switch links and presents all the switches as a single logical switch; the switching apparatus including ports coupling the apparatus to networks and to service applications and terminating applications on the modular computer systems; and sending the packet from network to modular computer system to which the packet is directed, or from modular computer system to network to which the packet is directed, the packet traversing none of the inter-switch links among the first layer switches. | 2012-10-18 |
20120263188 | SYSTEM FOR ADVERTISING ROUTING UPDATES - Systems and methods for advertising routing updates are disclosed. An example method includes forwarding a proposed routing update from a provider edge router to first and second customer edge routers when a route reflector determines that the proposed routing update having a first route target represents a desirable routing configuration for the provider edge router; and when the route reflector determines that the proposed routing update represents an undesirable routing configuration for the provider edge router: forwarding a first substitute routing update from the provider edge router to the first customer edge router different from the proposed routing update and including a second route target different from the first route target; and forwarding a second substitute routing update from the provider edge router to the second customer edge router different from the proposed routing update and including a third route target different from the first route target. | 2012-10-18 |
