A local domain is a domain that belongs to your company. For example, if you work for a company called Acme Coffee Shop and you have registered AcmeCoffeeShop.com with InterNic, you need to specify acmecoffeeshop.com as a local domain. When Xeams is running in Stand-Alone mode emails sent for local domain stay in Xeams.
Method and apparatus for determining latency between multiple servers and a client
InactiveUS7058706B1Reduce network trafficAccurately determineDigital computer detailsData switching networksTraffic capacityName server
A method and apparatus for determining latency between multiple servers and a client receives requests for content server addresses from local domain names servers (LDNS). POPs that can serve the content are determined and sent latency metric requests. The content server receives the request for latency metrics and looks up the latency metric for the requesting client. Periodic latency probes are sent to the IP addresses in a Latency Management Table. The IP addresses of clients are masked so the latency probes are sent to higher level servers to reduce traffic across the network. The hop count and latency data in the packets sent in response to the latency probes are stored in the Latency Management Table and is used to determine the latency metric from the resident POP to the requesting client before sending the latency metric to the requesting server. The BGP hop count in the Latency Management Table is used for the latency metric upon the first request for an IP address. The latency metric is calculated for subsequent requests of IP addresses using the hop count and RTT data in the Latency Management Table. Latency metrics from POPs are collected and the inverse relationship of the hop counts in a weighted combination with the RTT are used to determine which latency metric indicates the optimal POP. The address of the optimal POP is then sent to the requesting LDNS.

Method and apparatus for direct frame switching using frame contained destination information
InactiveUS20050027881A1Digital computer detailsData switching by path configurationImage resolutionEmbedded system
Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

Cname-based round-trip time measurement in a content delivery network
Round-trip time (RTT) for communication between an edge point of presence (POP) in a content delivery network (CDN) and a local domain name server (LDNS) is determined by resolution of a canonical name (CNAME) record. A first server in a first edge POP in a CDN receives a request to resolve a domain name from a LDNS and transmits a CNAME record including a timestamp indicating when the CNAME record was transmitted to the LDNS. The first server subsequently receives a request from the LDNS to resolve the CNAME record and determines a RTT time indicating the time needed for round-trip transmission between the LDNS and the first server based on the time when the request to resolve the CNAME request was received by the first server and the time indicated by the timestamp.

Determining address of closest edge server
A method and system is presented for bypassing a local Domain Name Server (DNS) when using edge caching servers. Domain names of frequently used business applications that are known to rely upon edge servers, together with the corresponding authoritative DNSs, are listed in both local hosts file and user defined FSFD local configuration file fsfd.conf. When the client computer's browser attempts to resolve a domain name, a File System Filtering Driver (FSFD) in the client computer intercepts the browser's request. If the domain name which is being resolved is found in a local FSFD configuration file fsfd.conf, then the FSFD initiates a DNS request directly to the appropriate authoritative DNS whose IP address gets extracted from the fsfd.conf record, thus bypassing the local DNS. The authoritative DNS returns the IP address for an edge caching server that is topographically proximate to the client computer's browser.

Rerouting in connection-oriented communication networks and communication systems
InactiveUS7180866B1Multiplex system selection arrangementsError preventionDouble faultCommunications system
A Private Network-Network Interface (PNNI) network including interconnected nodes is defined as a single rerouting domain (“global domain”) and the global domain is further defined by multiple divided domains (“local domains”). Each of the local domains is defined to include multiple nodes that are included in the network. Connection recovery and path optimization in the global domain (the entire PNNI network) are performed in accordance with a global rerouting protocol. The global rerouting protocol is a modification of the standard Domain-Based Rerouting (DBR) protocol, by adding information elements of domain identifier, rerouting for the global domain. The DBR protocol does not support the connection recovery from a link failure between local domains (“inter-domains”) and the global path optimization. The global rerouting method is capable of connection recovery and path optimization outside of any rerouting local domains. The global rerouting provides double fault recovery within the rerouting domain (“intra-domain”) as covered by the DBR and outside of the domains (“inter-domain”) or when the initial fault recovery within the domain has failed. Also, the global rerouting method provides maximum path optimization across all domains and within the rerouting local domain.

Techniques are disclosed for network distribution and provisioning of applications, such as transactional applications and parallel applications, across multiple administrative domains that ensure compliance with service level agreements. For example, a method of provisioning one or more resources in a distributed computing network to ensure compliance with a service level agreement associated with a computer application includes the following steps. Network performance is monitored between a local domain and one or more cooperating domains connected to the local domain by network paths. A present or predicted violation of the service level agreement is identified based on at least a portion of results of the monitoring step. One or more cooperating domains are selected that can effect compliance with the service level agreement by instantiating one or more network resources within at least one of the selected cooperating domains in response to a request from the local domain. Reconfiguration of the local domain is effectuated to allow the computer application to make use of the one or more newly instantiated network resources within the selected cooperating domain.

When load balancing (LB) for SIP message communication is performed across multiple SIP servers, the number of messages that must be processed by an LB server is reduced. The SIP LB server includes an LB management means which, if the previous hop source of a received request message is a terminal in the local domain, determines which SIP server to serve the terminal, and a redirect function which notifies the message source terminal in the local domain of the address of the serving SIP server. The SIP LB server further includes an LB management table which, if the previous hop source of a received request message is other than a terminal in the local domain, is searched to find a SIP server serving communication with a destination terminal in the local domain, and a stateless forwarding function which statelessly forwards the received request message to the resolved SIP server address.

Computation of a shortest inter-domain TE-LSP across a set of autonomous systems
A technique calculates a shortest path for a traffic engineering (TE) label switched path (LSP) from a head-end node in a local domain to a tail-end node of a remote domain in a computer network. The novel path calculation technique determines a set of different remote domains through which the TE-LSP may traverse to reach the tail-end node (e.g., along “domain routes”). Once the set of possible routes is determined, the head-end node sends a path computation request to one or more path computation elements (PCEs) of its local domain requesting a computed path for each domain route. Upon receiving path responses for each possible domain route, the head-end node selects the optimal (shortest) path, and establishes the TE-LSP accordingly.

Inter-domain path computation technique
ActiveUS20060171320A1Computationally efficientOptimization pathError preventionTransmission systemsPath computation elementLabel switching
A technique computes a traffic engineering (TE) label switched path (LSP) that spans multiple domains of a computer network from a head-end node of a local domain to a tail-end node of a remote domain. The novel inter-domain TE-LSP computation technique comprises a computation algorithm executed by the head-end node, which utilizes Path Computation Elements (PCEs) located within the remote domains (i.e., other than the local domain). Specifically, the head-end node requests path segments from a PCE in each of the remote domains, in which the path segments represent paths between all entry border routers to either all exit border routers of the particular remote domain (i.e., through the domain), or to the tail-end node. Upon receiving path segments from each remote domain, the head-end node combines the path segments with local domain information, and performs a forward path computation from the head-end node to the tail-end node to find the best (i.e., “shortest”) path.

Dynamic retrieval of routing information for inter-AS TE-LSPs
A technique dynamically triggers an exchange of reachability information between a tail-end (remote) domain target node (e.g., a tail-end node) of a traffic engineering (TE) label switched path (LSP) and a local domain head-end node of the TE-LSP in a computer network. The inter-domain information retrieval technique is illustratively based on triggering a Border Gateway Protocol (BGP) session whereby at least a portion of the reachability, i.e., routing, information of the tail-end node is transmitted to the head-end node of the TE-LSP in accordance with BGP. Specifically, once a TE-LSP is established between the head-end node and the tail-end node, the head-end node triggers the tail-end node, e.g., through extensions to a request / response signaling exchange, to establish the BGP session. Establishment of the BGP session enables transmission of the routing information from the tail-end node to the head-end node. The head-end node uses the routing information to calculate routes, i.e., address prefixes and associated attributes, reachable from the tail-end node for insertion into its routing table.

A method realizing the location management of an integrated network assigns location information for various types of terminals accessing the integrated network and finishes location registration by registering identities and location mapping of the terminals on a mapping server. When a terminal moves, a location update process is initiated toward the mapping server via an access router, and the update of terminal location information in the whole network is finished by means of information interaction among related entities. When a terminal initiates communication, the access router initiates a location query procedure toward the mapping server of the local domain, and by means of the cooperation of the mapping server of the local domain, the mapping server of the ownership domain of the destination terminal and the mapping server of the domain in which the destination terminal locates, the current location information of the destination terminal is obtained by query and returned to the access router of the source end to ensure that the access router can correctly initiate a communication connection.

A technique dynamically enforces inter-domain policy and quality of service (QoS) for Traffic Engineering (TE) Label Switched Paths (LSPs) between a local domain and a remote domain in a computer network. According to the enforcement technique, a Path Computation Element (PCE) of the local domain receives a path computation request for an inter-domain TE-LSP from the remote domain, and triggers a policy verification procedure at a Policy Decision Point (PDP) of the local domain. The PDP determines whether the requested TE-LSP is allowed based on configured policy for the remote domain and previously established TE-LSPs from the remote domain. In the event the requested TE-LSP is allowed and subsequently established, a Policy Enforcement Point (PEP) along the TE-LSP, e.g., a border router of the local domain or a dedicated server, updates the PDP with the state of the TE-LSP. In response to the update, the PDP returns a QoS template indicating configured QoS guidelines the PEP must enforce for that TE-LSP. If the TE-LSP is eventually torn down, the PEP again updates the PDP with the state of the TE-LSP.
