Abstract: One embodiment of the present invention provides a system for updating resource records in a name-server database. During system operation, a network node creates an update-request message containing a set of resource-record updates, and a requested lease, which specifies the length of time for which the name server is being requested to store the resource-record updates. Next, the network node sends the update-request message to a name server, which is part of a distributed system that provides a global naming service. The network node then receives a response message from the name server, wherein the response message contains a granted lease, which specifies the length of time for which the name-server database will store the resource-record updates.

Abstract: One embodiment of the present invention provides a system that implements a long-lived query (LLQ) at a name server. During operation, the system receives an LLQ from a client at the name server, wherein the LLQ requests information related to one or more data items stored on the name server. In response to the LLQ, the system informs the client of updates to the one or more data items.

Abstract: Dieses Dokument beschreibt einen „hybriden Proxy”, welcher ein Netzwerkknoten ist, der es Hosts außerhalb einer gegebenen Verbindung ermöglicht, Dienste zu ermitteln, die auf der Verbindung zur Verfügung stehen, durch die Beantwortung von Dienstermittlungs-Anfragen, die er von den Hosts außerhalb der Verbindung empfängt. Ein hybrider Proxy kann „Null-Konfigurations”-Netzwerktechnologien verwenden wie Multicast Domain Name System (mDNS), Domain Name System – Service Discovery (DNS-SD) und/oder Domain Name System Long-Lived Queries (DNS-LLQ). Beispielsweise kann ein hybrider Proxy eine Unicast-DNS-SD-Anfrage empfangen, eine entsprechende mDNS-Anfrage auf seiner Verbindung senden, um auf die Anfrage antwortende Information zu erhalten, und dann eine Unicast-DNS-SD-Antwort an den anfragenden Host schicken. In einem weiteren Beispiel kann ein hybrider Proxy eine Unicast-DNS-LLQ-Anfrage empfangen, eine initiale DNS-LLQ-Antwort an den anfragenden Host senden, eine mDNS-Anfrage auf seiner Verbindung senden, um zusätzliche Information zu erhalten, und dann anschließende DNS-LLQ-Aktualisierungs-Nachrichten an den anfragenden Host senden.

Abstract: A method for detecting a device that incorrectly responds to address-resolution-protocol (ARP) probes, comprising: in a network node: sending a first ARP probe for a link-local IP address; when a response is received to the first ARP probe, sending a second ARP probe for a reserved link-local IP address which should not be assigned to any device; and when a response is received to the second ARP probe, recording an identity of a responding device and ignoring subsequent ARP responses from the responding device.

Abstract: Embodiments of the present invention provide link-local IPv4 addressing across multiple interfaces of a network-node. During operation, the network-node broadcasts an address resolution protocol (ARP) request packet on multiple interfaces which asks for the hardware address of a network node whose link-local IPv4 address is Y. In response, the network-node receives an ARP-reply packet on an interface from a target network-node. If Y is present in the ARP cache and is associated with a different interface, the source network-node chooses a winner interface, and updates the ARP cache so that Y is associated with the winner interface. The network-node sends one or more contention-resolution packets on the loser interface to cause a loser network-node to choose another link-local IPv4 address for itself.

Abstract: One embodiment of the present invention provides a system that advertises a user interface for controlling and/or monitoring a service. During operation, the system advertises the user interface, wherein the user interface is accessible through a web browser. This advertisement can be used to determine an address for a web server that supports the user interface. Next, the system receives a request from a client to access the user interface, wherein the request is received at the web server. In response to the request, the system communicates information between the web server and a web browser associated with the client to provide the user interface to a user of the client, thereby enabling the user to control and monitor the service through the web browser. In this way, the present invention makes it possible to access the user interface by simply responding to the advertisement, without having to manually enter the address of the web server.

Abstract: One embodiment of the present invention determines if a domain name system (DNS) server is flawed. During operation, the system sends a special exploratory query to the DNS server, wherein the exploratory query is constructed to detect the existence of a flaw in the DNS server. If the answer from the DNS server indicates that a flaw exists in the DNS server, the system takes remedial action. Another embodiment detects a non-compliant router that incorrectly responds to all address-resolution-protocol (ARP) requests, including ARP requests for link-local IP addresses. This embodiment sends an ARP request asking for an Ethernet address associated with a reserved link-local IP address, which should not be assigned to any device. If a response is received to the ARP request, the system determines that the response was sent by a non-compliant router that incorrectly responds to all ARP requests, including ARP requests for link-local IP addresses.
