Abstract
A method of processing packets propagated over a packet switched communications network having a control plane, user plane, and a plurality of probes, the method comprising: receiving at least one control plane packet associated with creating at least one user session in the network; selecting a set of user sessions from the at least one user session; determining at least one target feature that characterizes packets propagated over the network; and load balancing all packets sharing the at least one target feature that belong to a same user session of the set of user sessions to a same probe of the plurality of probes for processing by the probe.
Claims19
A method of processing packets propagated over a packet switched communications network having a control plane, user plane, and a plurality of probes, the method comprising:
- receiving control plane packets associated with creating or modifying bearer for user sessions in the network;
- processing the received control plane packets to determine at least one target feature that characterizes packets propagated over the network in the user sessions with which the control plane packets are respectively associated;
- and
- selecting a set of user sessions from the user sessions associated with the received control plane packets;
- for each user session in the set of user sessions processing the received control plane packets to determine a session record comprising at least one characterizing feature of packets belonging to the session that is useable to associate the packet with the target feature and identify the packet as belonging to the session;
- logging the session record into a session table
- using the records in the session table to load balance packets sharing the same at least one target feature that belong to a same user session of the selected set of user sessions to a same probe of the plurality of probes for processing by the same probe;
- and
- throttling transmission rates by filtering of packets belonging to the selected set of user sessions responsive to a feature of the packets.
A method of processing packets propagated over a packet switched communications network having a control plane, user plane, and a plurality of probes, the method comprising:
- receiving control plane packets associated with creating user sessions in the network;
- selecting a portion of the user sessions associated with the received control plane packets;
- determining at least one target feature that characterizes packets propagated over the network;
- and
- for each user session of the selected user sessions processing the received control plane packets to determine a session record comprising at least one characterizing feature of packets belonging to the session that is useable to associate the packet with the target feature and identify the packet as belonging to the session;
- logging the session record into a session table;
- using the records in the session table to load balance packets that belong to the selected portion of the user sessions to the plurality of probes for processing.

- load balancing packets sharing the same at least one target feature that belong to a same user session of the selected set of user sessions to a same probe of the plurality of probes for processing by the same probe;
- throttling transmission rates of packets belonging to the selected set of user sessions responsive to a feature of the packets;
- processing the received control plane packets to determine, for each user session associated with the received control plane packets, an IMSI (International Mobile Subscriber Identity), an MS-IP (Mobile Subscriber-IP) address, and a GTP-U-TEID (GPRS Tunneling Protocol-User-Tunnel Endpoint Identifier);
- using the IMSI and/or MS-IP determined for each user session of the set of user sessions to determine an IP address for the same probe to which packets belonging to the user session and sharing the at least one target feature are load balanced;
- and
- for each user session in the set of user sessions, logging a record comprising the IMSI, MS-IP and GTP-U-TEID and probe IP address into a session table.
