摘要： A method, computer readable medium, and device for handling requests between different resource record types includes receiving at a traffic management device a first resource record type from one or more server devices in response to a request from a client device. The traffic management device validates the first resource record type, and creates a second resource record type corresponding to the first resource record type after the validating. Signing the second resource record type at the traffic management device is carried out for servicing the request from the client device.

摘要： A method, computer readable medium, and device for providing authenticated domain name service includes forwarding at a traffic management device a request for a domain name from a client device to one or more servers coupled to the traffic management device. The traffic management device receives a first response comprising at least a portion of the domain name from the one or more servers. The traffic management device attaches a first signature to the first response when the first response is determined by the traffic management device to be an unauthenticated response, and provides the first response with the first signature to the client device.

摘要： A method, computer readable medium, and device for dynamic DNS implementation, comprises receiving, at a network traffic management device, a first DNS response from a DNS server, wherein the first DNS response is compliant with Internet Protocol version 4 (IPv4). The first DNS response corresponds to a first DNS request from a client device being compliant with Internet Protocol version 6 (IPv6). The first DNS response is converted into a DNS second response that is compliant with IPv6, by attaching a prefix that identifies a network gateway device which is to handle receive subsequent non-DNS requests from the client device. The second DNS response is routed to the client device. Subsequent non-DNS requests from the client device that contain at least a part of the prefix allow the network traffic management device to route the non-DNS request through the designated network gateway device.

摘要： Embodiments are directed towards providing protection to DNS servers against DNS flood attacks by causing a requesting device to perform multiple DNS lookup requests for resolving a resource record. A request from a network device for a resolution of a domain name may be received by a device interposed between the requesting network device and a DNS server. Upon receiving the request to resolve the domain name, the interposed device may respond with a CNAME that includes a cookie. The requesting device may then send another request that includes the cookie preceded CNAME. The interposed device may then validate the returned cookie returned in the CNAME and if valid, forward the domain name resolution request on to a DNS server. The response may then be forwarded to the requesting device.

摘要： Disclosed are methods and systems for providing persistence across multiple requests in a WAN load-balanced environment. More than one load balancing system may be used to provide persistence while load balancing. One method and system disclosed provides persistence by using modulus arithmetic to load balance requests. Another method and system disclosed provides persistence using topology information contained in the request. Another method and system disclosed provides persistence by storing connection information to refer a timely continuation request of a prior request to the same server the prior request was referred to. When more than one load balancing system is used with this method, the load balancing systems periodically exchange the stored connection information so that each load balancing system may provide persistence to repeat requests.

摘要： Embodiments are directed towards employing a packet traffic management device that has a split data flow segment (“DFS”) and control segment (“CS”) to determine if a connection flow update provided by the DFS to the CS is valid. The CS may be utilized to establish connection flows at the DFS based on connection flow requests. The CS may generate a connection flow identifier (“CFID”) for a connection flow request. The CS may cache the CFID at the CS. The CS may establish a connection flow at the DFS based at least on the connection flow request and the CFID. After a connection flow is established, a DFS may provide a connection flow update and a corresponding CFID to the CS. The CS may determine that the connection flow update is valid if the corresponding CFID matches the CFID cached at the CS.
