DESCRIPTION
[0003] In the context of cloud computing, cloud service providers (CSPs) offer various services to other companies or individuals for use such as infrastructure as a service (IaaS), software as a service (SaaS) or platform as a service (PaaS). A hardware infrastructure including compute, memory, storage, accelerators, networking, and so forth executes and supports software stacks provided by the CSPs and their customers.
[0004] CSPs can have experience complex networking environments where packets are parsed, de-encapsulated, decrypted, and sent to a proper virtual machine (VM). In some cases, packet flows are balanced and metered to achieve service level agreement (SLA) requirements. In some cases, network processing occurs in the servers within a datacenter. However, with increased volumes of packets and increased amounts and complexity of packet processing activities, a burden on the servers is increasing. Central processing units (CPUs) or other server processor resources are used for packet processing, but CPUs and other processor resources can be used for other services that are billable or generate higher revenue than packet processing. The impact of this problem is significantly increased when using high bit-rate network devices such as the 100Gbps and higher speed networks.

Detailed Description
[0019] Within a data center, north-south traffic can include packets that flow in or out of the data center whereas east-west traffic can include packets that flow between nodes (e.g., racks of servers) within the data center. North-south traffic can be considered a product for serving customers, whereas east-west traffic can be considered overhead. The amount of east-west traffic has been growing at a rate that is significantly higher than north-south traffic and processing east-west traffic flow in a timely manner to comply with applicable SLAs while reducing data center total cost of ownership (TCO) is a growing challenge within the datacenter.
