US 10,321,360 B2 · Load balancing of wireless subscriber packet processing over multiple packet processing cores on a virtual machine platform

Abstract

Systems and methods related to the confinement, or “pinning,” of packet processing for a given wireless subscriber to a single “packet handler” core, to improve throughput in a telecommunication system and reduce the probability and incidence of cache misses. Packet header data can include a subscriber's tunnel endpoint identifier (“TED”) and/or a session identifier. A load balancer core can use one or both identifiers to select a packet handler core through which the packet's bidirectional traffic will be directed. A hashing algorithm can be used to distribute multiple UEs to each of multiple packet handler cores. Other embodiments relate to differentiating between system-initiated proxy traffic and downstream UE traffic using a partitioned multiprotocol label switching (“MPLS”) label space. For example, the MPLS label space can be split into a UE Pool Address Domain and a Proxy Loopback Address Domain.

Dependent claims

A computing system for sending packets to a packet handler core in a communications system comprising:

a processor;
and
a memory coupled to the processor and including computer-readable instructions that, when executed by the processor, cause the processor to:
receive a request to create a session wherein the request corresponds to a subscriber, allocate a downstream identifier and an upstream identifier to the session,
receive a data packet including the downstream identifier or the upstream identifier, determine if the data packet requires a proxy service, and
when it is determined that the data packet does not require the proxy service:
associate the downstream identifier and the upstream identifier to a session identifier, the session identifier uniquely identifying the session,
identify the session identifier associated with the data packet based on the downstream identifier or the upstream identifier,
route the data packet to the packet handler core based on the session identifier, and
when it is determined that the data packet requires a proxy service:
identify a proxy service for the data packet,
route the data packet to the proxy service,
correlate an identifier for the packet handler core with the downstream identifier, and
route the data packet to the packet handler core based on the identifier for the packet handler core.
