Abstract: A computer program product includes program instructions configured to be executable by a processor of a networking hardware device to cause the processor to perform various operations. The operations include monitoring network communications on a first port of the networking hardware device to identify a first network address of a first device attached to the first local port and determining that the first network address is incompatible with communication on an external network. The operations further include automatically configuring, in response to determining that the first network address is incompatible with communication on an external network, independent network address translation for the first local port to translate the incompatible first network address to a compatible network address for all egress traffic from the first device and to translate the compatible network address to the incompatible first network address for all ingress traffic to the first device.

Abstract: A method for converting network packets and a circuit system are provided. The circuit system uses firmware therein to record tables for implementing packet conversion between two types of networks (IPv4 and IPv6). In the method, a process of mapping of address and port using encapsulation (MAP-E) or a process of mapping of address and port using translation (MAP-T) is determined according to IPv4 packets routing requirement to embody an uplink and a downlink packet conversion process. A content table stores an IPv6 packet header after the MAP-E or MAP-T process. A control table is referred to for controlling the fields to be updated when adding the IPv6 packet header. A forwarding mapping rule table is referred to for determining to convert a destination IP address of an uplink IPv6 packet, or both a source IP address and a destination IP address of a downlink IPv4 packet.

Abstract: A method and a device are disclosed for address resolution protocol (ARP) operation in a communication system supporting multiple links. An operation method of a first device comprises the steps of: receiving, from a communication node, an ARP request packet requesting the transmission of a MAC address of a second device connected to the first device; finding, in an ARP table stored in the first device, a representative MAC address of the second device requested by the ARP request packet; and transmitting an ARP response packet including the representative MAC address to the communication node.

Abstract: Described herein are systems and methods to apply route-map configurations in a computing network. In one implementation, a routing computing system may identify a route for redistribution in a computing network and identify a longest prefix in a radix tree associated with the route. The routing computing system may further identify a highest priority route-map clause associated with the longest prefix match or any parent prefixes of the longest prefix match in the radix tree. Once identified, the computing system may perform an action associated with the highest priority route-map clause.

Abstract: Low latency wireless communications may be provided. A client device may be authorized for a first association in response to the client device making a first concurrent association request that may include a first Media Access Control (MAC) address. In response to authorizing the client device for the first association, an Endpoint Identifier (EID) associated with the client device may be registered with a first Routing Locator (RLOC) in a map server, the first RLOC being associated with the first MAC address. The client device may then be authorized for a second association in response to the client device making a second concurrent association request that includes a second MAC address. In response to authorizing the client device for the second association, the EID associated with the client device may be registered with a second RLOC in the map server, the second RLOC being associated with the second MAC address.

Abstract: A network address translation (NAT) device may receive a network packet having a network address for translation. The NAT device may determine whether a translation for the network address exists on the NAT device. The NAT device may forward the network packet to a peer NAT device based on a criterion.

Abstract: A computer program product, system, and computer implemented method for application-level redirect trapping and creation of NAT mapping to work with routing infrastructure for private connectivity in cloud and customer networks. The approach disclosed herein generally comprises a method of leveraging a reverse connection endpoint and IP address mapping controller to capture redirection messages from a private cloud or network (e.g., a service consumer network or a service consumer hybrid cloud). This allows at least the IP address mapping controller to manage a cloud networking infrastructure to provide for a service provider network (e.g., a public cloud) to support applications that overcome the isolation requirements of a private cloud or network to perform useful work. For example, without saddling the private cloud or network user with a heavy pre-configuration burden, the approach disclosed herein supports redirection to dynamically determined IP addresses at the private cloud or network.

Abstract: One aspect provides a method and system for managing address resolution requests in a network. During operation, a gateway of the network advertises a route for sending address resolution requests and determines whether a cached entry corresponding to an address resolution request received via the route exists in a neighbor table. In response to determining that the cached entry exists, the gateway responds to the address resolution request based on the cached entry; in response to determining that the cached entry does not exist, the gateway replicates the address resolution request to edge devices in the network, thereby facilitating discovery of a target host corresponding to the address resolution request.
