Publication number: 20140286335Abstract: A Multicast-Enabled Address Resolution Protocol (ME-ARP) is disclosed. This ME-ARP allows the building of independent IP based Virtual Private LAN segments (VPLS) over a multicast enabled IP backbone using stateless tunnels and optimal VPLS traffic forwarding. Each VPLS has an associated IP subnet which is completely independent from other VPLS or the underlying IP backbone itself. Each Customer Premises Equipment (CPE) device needs only to be configured with a VPLS identifier and its serving IP subnet per VPLS designated interface.Type: ApplicationFiled: June 9, 2014Publication date: September 25, 2014Inventors: Marcel Wiget, Robert Pluim, Simon David Bryden, Geoffrey Mattson

Publication number: 20130188643Abstract: A hybrid data center switching system includes a first switching device, a routing/switching device, a core switching device and communication links. The first switching device has a plurality of external packet interfaces and a plurality of external fabric interfaces. The external packet interfaces are configured to receive and transmit data packets in accordance with a standards-based packet protocol. The external fabric interfaces are configured to receive and transmit data packets in accordance with a fabric protocol. The routing/switching device is coupled to the plurality of external packet interfaces via a first communications link. The core switching device has a packet interface and a fabric interface. The packet interface is coupled to the routing/switching device via a second communications link. A third communications link between the external fabric interfaces and the fabric interface of the core switching device is operable for transporting data packets in accordance with the fabric protocol.Type: ApplicationFiled: September 10, 2012Publication date: July 25, 2013Applicant: Futurewei Technologies, Inc.Inventor: Geoffrey Mattson

Patent number: 7864789Abstract: A platform is connected over a synchronous network using a GFP encapsulation scheme to a provider device having a first Ethernet interface with a customer device, said platform being arranged for exchanging tagged frames including a virtual LAN identifier (VID) with a service unit over a second Ethernet interface. If an error condition is detected at a GFP port of the platform, a correspondence is retrieved between said GFP port and a VID and a deregistration message including said VID is forwarded to the service unit. If an error condition is detected at the second Ethernet interface responsive to reception of a deregistration message including a VID from the service unit, a correspondence is retrieved between said VID and a GFP port and said deregistration message is forwarded through said GFP port to the provider device in a GFP error message. When several Ethernet interfaces concentrated by a bridge face the provider device, another VID is taken into account in the correspondence retrieving.Type: GrantFiled: June 28, 2002Date of Patent: January 4, 2011Assignee: Ciena CorporationInventors: Michael Tate, Geoffrey Mattson, Simon Bryden, Robert Pluim

Patent number: 7221675Abstract: A virtual private network (VPN) service is provided through a shared network infrastructure, with customer edge (CE) devices each having a provider edge (PE) interface having a single layer 3 address in the VPN. An address resolution request message is transmitted by a first CE device on plural layer 2 virtual circuits of its PE interface. The address resolution request message including the layer 3 address allocated to a second CE device of the VPN. In response to reception of such request message at the second CE device, an address resolution response message is returned to the first CE device. In response to reception of this response message, the first CE device maps the layer 3 address allocated to the second CE device to a virtual LAN identifier of the layer 2 virtual circuit on which the response message is received.Type: GrantFiled: January 22, 2002Date of Patent: May 22, 2007Assignee: Nortel Networks LimitedInventors: Simon Bryden, Michael Tate, Geoffrey Mattson

Publication number: 20030110287Abstract: A primary label switched path (LSP) defined in a label switching network has a protected portion for transmitting data packets containing a label stack from a first label switching node to a second label switching node, the protected portion including at least one intermediate label switching node between the first and second nodes. To provide path recovery resources in case of link or node failure, it is proposed a method in which a backup LSP is defined from the first node to the second node. A transformation of the label stack of a packet transmitted along the protected portion of the primary LSP from an output of the first node to an input of the second node is determined. The first node is configured to switch a packet to the backup LSP upon detection of a failure in the protected portion of the primary LSP. In addition, a node of the backup LSP is configured to process the label stack of any packet transmitted along the backup LSP so as to apply the determined transformation.Type: ApplicationFiled: January 22, 2002Publication date: June 12, 2003Inventor: Geoffrey Mattson
