    摘要： Techniques are described for load balancing between DHCP servers at a DHCP client. Embodiments receive load information from each of two or more DHCP servers. Here, the load information describes a current workload of the respective DHCP server from which the load information is received. One of the two or more DHCP servers is then selected at the DHCP client based on the received load information. Additionally, embodiments accept an IP address offer from the selected DHCP server.

    摘要： Systems, methods and articles of manufacture are disclosed for resolving hostnames on a private network with a distributed DNS server configuration. One embodiment of the invention provides for a client resolver configured to communicate with a distributed network of servers. The client resolver receives a hostname query and determines if the hostname query is of the type single lablel hostname or fully qualified hostname. If the hostname query received is of the type fully qualified hostname, the client resolver routes the hostname query to a server with a longest matching domain suffix. If the hostname query received is of the type single label hostname the client resolver generates one or more new fully qualified hostnames and routes the hostname query to each server on the private network.

    摘要： Techniques are described for providing a backup DHCP server using a DHCP relay agent. Embodiments retrieve DHCP server configuration information specifying a configuration of one or more DHCP servers. Additionally, embodiments monitor, at a DHCP relay agent, DHCP lease traffic between the one or more DHCP servers and one or more DHCP clients passing through the DHCP relay agent. Upon determining that the one or more DHCP servers have failed, DHCP server services are provided at the DHCP relay agent, based on the received DHCP server configuration information and the monitored DHCP lease traffic.

    摘要： A host node connected to a network using an Internet Protocol automatically identifies multiple adapters connected to the same network, preferably by broadcasting a Dynamic Host Configuration Protocol (DHCP) request for assignment of an IP address on a first adapter, and listening to the request on a second adapter, thereby determining that both adapters are on the same network. The host preferably causes an IP address to be generated for one of the adapters, and automatically configures the adapters to share the IP address thus generated as a virtual IP address, assigning one of the adapters as a primary adapter. Preferably, the host automatically detects deactivation of the primary adapter and switches the virtual address assignment to a different adapter.

    摘要： systems methods and computer products for reclaiming resident buffers on demand. Exemplary embodiments include systems and methods for reclaiming resident buffers, including allocating a buffer, determining that the buffer alllocation pushes the buffer pool below a reclaim threshold, marking an oldest in-use buffer to be reclaimed, determining that all messages referencing the buffer have been queued, allocating a new buffer and performing a swap of the oldest in-use buffer and the new buffer, performing a free message block operation and updating a message block by updating a set of read and write pointers to point to the new buffer.

    摘要： Systems, methods and articles of manufacture are disclosed for updating IP addresses on a private network. A DNS server receives an updated IP address and stores both the updated IP address and an old IP address. The DNS server includes the updated IP address in responses to all DNS query requests, wherein the DNS query requests are to the old IP address. Further, the DNS server deletes the old IP address and updates the DNS server network settings with the updated IP address after every remote client on the private network has stored the updated IP address.
