20090019135 | Method, Network and Computer Program For Processing A Content Request - The embodiments described herein provide a method, program and computing network for processing a content request received via a computing network. The method comprises the steps of receiving an incoming request for content from a remote computing device, determining the content type requested by the incoming request and delivering the request to one of a plurality of servers according to the determined content request type. | 01-15-2009 |
20100020795 | System And Method For Broadcast Pruning In Ethernet Based Provider Bridging Network - A system and method for delivering multicast/broadcast data frames, originating in a service virtual local area network (S-VLAN), to a plurality of locations on a customer network is disclosed. In one embodiment, a method for delivering multicast/broadcast data frames includes analyzing ingress data frames, including customer virtual local area network identifiers (C-VIDs) associated with one or more divisions within one of a plurality of locations assigned by a customer network, received via incoming ports of each Ethernet switch associated with one of the plurality of locations and learning the C-VIDs of the ingress data frames, storing the learnt C-VIDs in the Ethernet switch, and forwarding the multicast/broadcast data frames to the one or more of the plurality of locations, via one or more outgoing ports of one or more of multiple Ethernet switches associated with the plurality of locations, based on the learnt and stored C-VIDs by each Ethernet switch. | 01-28-2010 |
20100098082 | METHOD FOR APPLICATION BROADCAST FORWARDING FOR ROUTERS RUNNING REDUNDANCY PROTOCOLS - A method for application broadcast forwarding for routers running redundancy protocols in a network is provided. The network includes a first router running at least one program instance of a redundancy protocol at one interface, and a second router running at least one program instance of the redundancy protocol at one interface. A relay agent is enabled on both the first and second routers. The method includes, for each router, determining at least one preference ID for the router, determining a broadcast ID of each incoming broadcast packet, matching the broadcast ID of the incoming broadcast packet with the at least one preference ID of the router, and relaying the incoming broadcast packet from a first network domain to a second network domain if the broadcast ID of the incoming broadcast packet matches one preference ID of the router. | 04-22-2010 |
20100274894 | Router Method And System - A method and system for operating a virtual router system. A system health index for each of a plurality of physical routers in a virtual router system is determined, and virtual router operation for the physical routers is suspended in response to the system health index. | 10-28-2010 |
20150222446 | Discovering IP Multicast Group Memberships in Software Defined Networks - Provided is a method of discovering multicast group memberships in a software defined network. A multicast group membership query message is sent only to a selected network device in the network. The network device forwards the multicast group membership query message to a host computer system connected to the network device and recognizes a multicast group membership request from the host computer system in response to the group membership query message. | 08-06-2015 |
20160028589 | DATA LOOP DETECTION - Data loop detection can include receiving, from a network controller, a forwarding rule at a designated network device, forwarding a loop-detect unit, via the designated network device, utilizing the received forwarding rule, and determining if the loop-detect unit is received by the designated network device. | 01-28-2016 |
20160036644 | LOOP-FREE HYBRID NETWORK - A loop-free hybrid network can include receiving an advertisement from a non-software defined network (SDN) network device, determining a network topology that includes the non-SDN network device and a number of SDN network devices, and sending an aggregating instruction to the non-SDN network device, wherein the aggregating instruction aggregates all connections between the non-SDN network device and the number of SDN network devices. | 02-04-2016 |
20160142365 | ADDRESS RESOLUTION REWRITING - A network controller may rewrite an address resolution request and an address resolution response. The address resolution request may be rewritten by changing a request source link address to a link address of a first switch. The address resolution response may be rewritten by changing a response source link address to a link address of a second switch. | 05-19-2016 |
