Abstract: A resource negotiation service is provided to enable business logic decisions to be made when obtaining switched underlay network resources, to interface business logic with network conditions and schedules. The resource negotiation service may be implemented as a web service or other network service to enable business logic to be used in the selection of available network resources. This may allow policy to be used on both the subscriber side and the network provider side to optimize network resource allocations for a proposed transfer. The policy may include subscriber policy, network policy, and other factors such as current and expected network conditions. The resource negotiation service may include an interface to enable existing subscribers and new customers to obtain switched underlay resources.

Abstract: A method and apparatus for efficiently performing a longest match search are provided. According to one aspect of the present invention, an entry in a forwarding database, a routing table, or the like is located using an improved longest match search. A mask is applied to an address, such as a destination Internet Protocol (IP) address, to determine a masked address that is to be used for purposes of locating a matching entry in the forwarding database. The forwarding database is searched for an entry that matches the masked address. Subsequent masks are produced by performing an address-sensitive decimation of the former mask. For example, the former mask may be shortened based upon the location of the least significant bit containing a one in the masked address. According to another aspect of the present invention, data forwarding employs the improved longest match search. Data is received at a port. An address is extracted from the data.

Abstract: The present invention provides a transfer control protocol handoff notification (TCPHN) mechanism for a wireless network by which hosts connected through the wireless network via a transfer control protocol (TCP) connection can be notified in the event a handoff occurs. The TCPHN mechanism allows hosts connected in TCP to avoid TCP timeouts and reduce any adverse effect on transmission performance. The TCPHN mechanism of the present invention can be used in relation to any TCP connection between any transmitting and receiving host where at least one of the transmitting and receiving hosts is mobile and subject to handoffs. In one embodiment for example, the TCPHN mechanism is used in relation to a TCP connection between a mobile host in a wireless network and a non-mobile server host in a connecting Internet protocol (IP) network.

The actuator is connected to the board for rotational movement about a pivot point between a first position in which the actuator is adjacent to the release tab of the fiber optic cable assembly and a second position in which the actuator engages the release tab and urges the release tab into an unlatched position so that the fiber optic cable assembly can be disconnected from the adapter of the optical module.

Abstract: A self-configuring distributed packet switch which operates in wavelength division multiplexed (WDM) and time division multiplexed (TDM) modes is described. The switch comprises a distributed channel switching core, the core modules being respectively connected by a plurality of channels to a plurality of high-capacity packet switch edge modules. Each core module operates independently to schedule paths between edge modules, and reconfigures the paths in response to dynamic changes in data traffic loads reported by the edge modules. Reconfiguration timing between the packet switch modules and the channel switch core modules is performed to keep reconfiguration guard time minimized. The advantage is a high-capacity, load-adaptive, self-configuring switch that can be distributed to serve a large geographical area and can be scaled to hundreds of Tera bits per second to support applications that require, very high bandwidth and a guaranteed quality of service.

Abstract: Described are a system and method for managing a service transported over a transport network. Service traffic is transmitted from a first network element to a second network element over a transport network. If one of the network elements detects a condition occurring in the transport network, the network element determines each service affected by the condition. Service traffic performance is measured at each of the first and second network elements. Each network element correlates its measure service traffic performance and the service to produce a performance of service (PoS) service metric. Each network element transmits its measured PoS service metric to the other network element over a service management channel. This enables each network element to correlate both performance (SPC) and fault (SFC) for both near and far end service metrics and enables a complete end to end service definition in support of a service level agreement (SLA).

A first node detects a next node, and a channel is created between the first node and the next node. A first packet is received at the first node and the protocol of the first packet is detected. The first packet is merged with a second packet having the same protocol as the first packet, and the merged first packet and second packet are transmitted to the next node via the channel.

Abstract: Described are a system and method for establishing zone-based pricing for services transported over connectionless and connection-oriented networks. The connectivity network supporting the service is partitioned into one or more zones. A node connected to a packet transport network receives a packet associated with the service. The packet has information that is used to identify one of the zones of the connectivity network to which the packet can be transmitted. Service providers are thus able to use zoning to apply a pricing structure for services traditionally lacking distance-based pricing, such as Ethernet, Storage, and Internet Protocol services.

Abstract: Described are a system and method for identifying private resources associated with a communications network. A structured address format is defined having a plurality of character positions. Each character position is associated generally with a property of a managed resource in the communications network. A structured private address, constructed according to the structured address format, is assigned to the managed resource. Each character position of the assigned structured address has a value that identifies a specific instance of the property of the managed resource associated with that character position. Operations Systems Support (OSS) gives a common name to the managed resource and maintains an association between the common name and the structured address. The structured address format can follow a four-byte dotted decimal notation similar to IPv4 addresses.

Abstract: Described are a system and method for managing a service transported over a transport network between first and second service termination points. Packet traffic associated with the service is received at a service termination point connected to the transport network. Performance of the packet traffic is measured at the service termination point. The measured performance of the packet traffic and the service are correlated to produce a performance of service (PoS) service metric. Based on the PoS service metric, other service metrics associated with the service are correlated, including a rate of service (RoS) service metric and availability of service (AoS) service metric. These service metrics can be used to develop service level agreement (SLA) and service level metrics that define the operation of the service and operation of the network supporting those services.

Abstract: A system and a method of selecting gateways using stored metrics associated with each route out of the domain and with each destination is presented. The metrics represent some measure to be minimized by the routing system, such as cost or delay. The route is selected quasi-deterministically. A first selection is made deterministically based on the stored metrics in order to attempt to use the optimum path. If a connection can not be established through the deterministically selected gateway, an alternate gateway is selected randomly from among the remaining gateways capable of reaching the destination at a reasonable cost.
