`
`As streaming video, peer-to-peer networking, and other high bandwidth applications
`
`become the norm, the burdens placed on the underlying network architecture increase exponentially.
`
`When designing the congestion management systems, service providers did not contemplate the use
`
`of the Internet for streaming video, peer-to-peer applications, and other high bandwidth uses. As a
`
`result, when a large number of users run high-bandwidth applications, the best effort, high
`
`oversubscription rate architecture frequently experiences congestion, thereby interfering with the user
`
`experience.
`
`[0003]
`
`These problems are particularly salient in the context of mobile networks, where
`
`bandwidth is even more limited. Mobile networks are seeing a gradual transformation from voice-
`
`only services to data or mixed voice-data services. As per-user bandwidth requirements have
`
`increased, the burdens placed on the mobile network architecture have also increased.
`
`[0004]
`
`Service providers, particularly mobile network service providers, must therefore decide
`
`between several options: continue providing best effort service; increase bandwidth and essentially
`
`become a transport “utility”; or sell application-specific services based on the requirements of the
`
`individual users. Service providers view the first two options as unsatisfactory, as users are
`
`dissatisfied with best effort service, while indiscriminately increasing bandwidth would result in

`
`additional costs to the service provider with no corresponding increase in revenue. Selling
`
`application-specific services, on the other hand, would allow users to pay for the services they desire
`
`to receive, while eliminating the need for the service provider to exponentially increase bandwidth.
`
`[0005]
`
`In order to sell application-specific services, however, service providers must first modify
`
`the underlying network architecture to identify and gather information about applications.
`
`In the
`
`radio portion ofmobile networks, the use ofper-application traffic management is especially critical,
`
`as bandwidth is limited due to the inherent restrictions of radio fiequencies. Consequently, mobile
`
`operators frequently utilize packet marking, such as Type of Service (ToS) marking to prioritize and
`
`forward packets.
`
`[0006]
`
`In existing mobile network architectures, however, the network relies on end-user
`
`equipment for proper marking of packets. Thus, for example, a user’s mobile handset could mark
`
`voice packets as having a higher priority than data packets, thereby ensuring the quality of calls
`
`placed over the mobile network.
`
`[0007]
`
`In these current implementations, because the network relies on end-user equipment to
`
`mark packets, the mobile network cannot effectively prioritize packets without involvement of end-
`
`user equipment supported by the mobile network. In addition, because values must be predefined
`
`and implemented in the end-user equipment, the mobile network operator lacks the flexibility to
`
`define new applications and markings without modifying the behavior of the end-user equipment.
`
`Furthermore, current implementations rely on packet marking protocols that include only a limited
`
`number of unique values, such that the network can effectively manage only a small number of
`
`applications.

`
`[0008]
`
`Still further, current implementations treat all data packets associated with an application
`
`in the same manner. For example, a current implementation might modify a quality of service
`
`assigned to every packet in a data flow. Accordingly, current implementations fail to consider that
`
`some packets associated with an application flow are more important than others and therefore fail to
`
`most efficiently utilize bandwidth in the network.
`
`[0009]
`
`Accordingly, there is a need for an in-line device that identifies characteristics of
`
`applications associated with data packets and conveys this information for downstream processing.
`
`There is also a need for associating application characteristic information with data packets without
`
`requiring the packet to be marked at end—user equipment.
`
`In addition, there is a need for packet
`
`marking in a mobile network that utilizes a packet marking scheme such that a large number of
`
`applications and application characteristics may be identified at any location in the network, without
`
`requiring Deep Packet Inspection (DPI) processing to be performed at each location. Furthermore,
`
`there is a need for identifying characteristics of applications to allow downstream processing of
`
`packets based on the importance of the packets to the application flow.

`
`SUMMARY OF THE INVENTION
`
`[0011]
`
`In light of the present need for in-band DPI application awareness propagation
`
`enhancements, a brief summary of various exemplary embodiments is presented.
`
`Some
`
`simplifications and omissions may be made in the following summary, which is intended to highlight
`
`and introduce some aspects of the various exemplary embodiments, but not to limit the scope of the
`
`invention. Detailed descriptions of a preferred exemplary embodiment adequate to allow those of
`
`ordinary skill in the art to make and use the inventive concepts will follow in later sections.
`
`[0012]
`
`In various exemplary embodiments, a DPI device is placed in-line in a non-mobile portion
`
`of a mobile network, such that packets pass through the DPI device prior to being forwarded. Thus,
`
`in various exemplary embodiments, the DPI device identifies and classifies traffic passing through
`
`the mobile network based on information extracted from the header and/or data portion of the
`
`incoming packets. Using the information extracted from the packets, the DPI device may add an
`
`application classification to the packets, thereby allowing downstream devices to identify the packet
`
`and perform application-specific processing.
`
`[0013]
`
`Accordingly, in Various exemplary embodiments, a method of processing packets sent
`
`from a source node to a destination node and a related computer-readable medium comprise:
`
`receiving a packet sent from the source node to the destination node; associating the packet with an
`
`active flow by accessing information in the packet; performing deep packet inspection (DPI) to

`
`identify an application associated with the active flow; determining a classification for the packet
`
`based on characteristics of the identified application; associating, with the packet, information
`
`identifying the classification; forwarding the packet including the information identifying the
`
`classification towards the destination node; and performing processing on the packet at a
`
`downstream device by extracting the classification from the packet.
`
`[0014]
`
`In various exemplary embodiments, the packet is an IP packet and the information
`
`identifying the classification is placed in a header extension of the IP packet. Alternatively, in
`
`various exemplary embodiments, the packet is formatted according to a proprietary protocol and the
`
`information identifying the classification is placed in a proprietary protocol extension of the packet.
`
`In addition, in various exemplary embodiments, the packet is a Generic Routing Encapsulation
`
`(GRE) packet and the information identifying the classification is placed in a key field of the GRET
`
`packet or a sequence number of the GRE packet.
`
`[0015]
`
`In various exemplary embodiments, the step of determining a classification for the packet
`
`considers at least one ofan effect ofthe packet on a user experience and an importance ofthe packet
`
`to an application. Furthermore,
`
`in various exemplary embodiments,
`
`the step of performing
`
`processing on the packet at a downstream device comprises performing a traffic management
`
`function on the packet, which may include dropping the packet and modifying a quality of service
`
`associated with the packet.
`
`[0016]
`
`Finally, in various exemplary embodiments, a device for processing traffic in a network
`
`comprises: a communication module that receives and forwards a packet sent from a source node to a
`
`destination node; and a processor configured to identify an active flow associated with the packet by

`
`accessing information stored in the packet, perform deep packet inspection (DPI) to identify an
`
`application associated with the active flow, determine a classification for the packet based on
`
`characteristics of the identified application, and associate, with the packet, information identifying
`
`the classification, wherein the information identifying the classification is extracted from the packet

`
`In various exemplary embodiments, DPI device 150 comprises specialized hardware
`
`and/or software that is capable of examining data packets received from or transmitted to radio
