    Abstract: Techniques are described for managing customer-specified routing policies for network-accessible computing resources. In some situations, the customer-specified routing policies may be based at least in part on DNS (“Domain Name System”) information specified by a customer, such as if the customer specifies one or more target destinations to use with an indicated DNS domain name that are different from the destination IP address(es) provided for that DNS domain name by DNS servers—if so, the managing of such a DNS-based routing policy for that customer may include identifying when network-accessible computing resources provided to the customer send electronic communications to that DNS domain name, and causing those electronic communications to be redirected to the customer-specified target destination(s). Such customer-specified target destinations may include, in different situations, final destinations, intermediate destinations, etc., as well as identify particular routes.

    Abstract: In various methods and apparatus Internet Protocol (IP) addresses can be moved between virtual machine instances in a provider network. Customers can cause an IP address to be moved between virtual machine instances such as by submitting an application programming interface call. The provider network also may include a server system that implements the dynamic host configuration protocol such as the DHCP for version 6. The DHCP server system moves the requested IP address by exchanging messages with the effected instances. The DHCP server system may transmit a message to remove the IP address from a first instance by including the IP address with a valid lifetime set to a minimal time-out value. The DHCP server system may transmit a message to add the IP address to a second instance by including the IP address and a corresponding valid lifetime value of greater than the minimal time-out value.

    Abstract: Methods and apparatus for private network peering in virtual network environments in which peerings between virtual client private networks on a provider network may be established by clients via an API to a peering service. The peering service and API 104 may allow clients to dynamically establish and manage virtual network transit centers on the provider network at which virtual ports may be established and configured, virtual peerings between private networks may be requested and, if accepted, established, and routing information for the peerings may be specified and exchanged. Once a virtual peering between client private networks is established, packets may be exchanged between the respective client private networks via the peering over the network substrate according to the overlay network technology used by the provider network, for example an encapsulation protocol technology.

    Abstract: Systems and methods are described to provide fault tolerant folded Clos networks. A folded Clos network is disclosed including a set of tier 1 routers interconnected with a set of tier 2 routers. Tier 1 routers are configured to view a set of tier 2 routers as a single aggregate router. Accordingly, tier 1 routers are unaware of faults between tier 2 routers and additional tier 1 routers. A throwback router is connected to each tier 2 router to facilitate handling of data under such fault conditions. When a tier 2 router receives undeliverable data, the data is passed to a throwback router, which retransmits the data to an additional tier 2 router. Data that is retransmitted multiple times can be disregarded by the throwback router.

    Abstract translation: 描述了系统和方法来提供容错折叠Clos网络。 公开了一种折叠Clos网络，其包括与一组二层路由器互连的一层层次1路由器。 一级路由器被配置为将一组二层路由器视为单个聚合路由器。 因此，第1层路由器不知道第2层路由器和其他1级路由器之间的故障。 一个倒带路由器连接到每个二层路由器，以便于在这种故障条件下处理数据。 当二层路由器接收到不可投递的数据时，数据将被传递给一个丢弃的路由器，该路由器将数据重发到另一个二层路由器。 多次重传的数据可以被丢弃路由器忽略。
