`
`TECHNICAL FIELD
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`(G@G2] This disclosure generally relates to techniques for deep packet inspection (DP),
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`and particularly for DPI of traffic in cloud-based networks utilizing saftware defined
`networks.
`
`
`
`
`
`BACKGROUND
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`[003] Deep packet inspection (DPI) technology is a form of network packet scanning
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`technique that alows specific data patterns to be extracted from a data communication
`
`
`
`
`
`
`
`
`
`
`
`
`channel. Extracted data patierns can then be used by various applications, such as
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`security and data analytics applications. DPi currently performs across various
`
`
`
`
`
`
`
`networks, such as internal networks,
`
`
`
`
`
`
`
`
`internet service providers (ISPs}, and public
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`networks provided to customers. Typically, the DF is performed by dedicated engines
`
`
`
`
`
`
`installed in such networks.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`{O04] A software defined networking is a relatively new type of networking architecture
`
`
`
`
`
`
`
`
`
`
`
`
`
`that provides centralized management of network nodes rather than a distributed
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`architecture utilized by conventional networks. The SDN is prompted by an ONF (open
`
`
`
`
`
`
`
`
`network foundation). The leading communication standard that currently defines
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`communication between the central contrailer (e.g., a SDN controller} and the network
`
`
`
`
`
`
`
`nodes (e.g., vSwitches) is the OoenFlow™standard.
`
`
`
`
`
`
`
`
`
`
`
`{005] Specifically,
`in SDON-based architectures the data forwarding (e.g. data plane) is
`
`
`
`
`
`
`
`
`
`
`
`typically decoupled from control decisions (e.g. contrcl plane}, such as routing,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`resources, and other management functionalities. The decoupling may also allow the
`
`
`
`
`
`
`
`
`
`
`
`
`
`data plane and the control plane to cperate on different harcware, in different runtime
`
`
`
`
`
`
`
`
`
`
`
`
`environments, and/or operate using diferent models. As such, in an SDN network, the

`
`
`
`
`
`
`
`
`
`
`
`
`through the various networking layers as defined by the OSI model. Specifically, the
`
`
`
`
`
`
`
`
`
`
`
`
`current OpenFlow specification defines a mechanism to parse and extract only packel

`
`
`headers, in layer-2 through layer-4, fram packets flowing via the network nodes. The

`
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`generic, uncommon, and/or arbitrary data patterns contained in layer-4 to layer 7 fleids.

`inspection (DP) in a software defined network (SDN), wherein the method is performed
`
`
`
`
`
`
`
`
`
`
`
`
`
`by a central controller of the SDN. The method comprises: configuring a plurality of
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`network nodes operable in tne SDN with at least one probe instruction: receiving from a

`
`
`
`
`

`network node a first packet of a flow, wherein the first packet matches the at least one
`
`
`
`
`
`
`
`
`
`
`
`
`probe instruction, wherein the first packet includes a first sequence number; receiving
`
`
`
`

`
`
`
`
`
`

`
`
`value respective of at least the first and second sequence numbers, wherein the mask
`
`
`
`

`value indicates which bytes to be mirrored from subsequent packels belonging to ihe
`
`
