Abstract
Systems, methods, and devices are disclosed that provide packet protection for header modification. One method includes receiving a packet to a computing device. The method includes apply error checking techniques independently to different portions of the packet.
Claims20
A network device, comprising:
- logic associated with the operations of a data communications protocol stack;
- and
- wherein the logic which can operate to:
- receive a packet to the network device;
- and
- apply error checking techniques to different portions of the packet.
3 more elements
A computing device, comprising:
- a number of network chips including ports to receive a packet to the network device, at least one network chip includes means for:
- providing a first verification key to a body of the packet;
- and
- providing a second verification key to a header associated with the packet.
1 more element
A network, comprising:
- a number of network devices connected to one another;
- a number of ports to transmit a packet received to at least one of the number of network devices;
- and
- logic on one of the network device operable as a layer three (3) switch to:
- check a first verification key associated with a data portion of the packet;
- add different verification keys to one or more different headers associated with the packet as the packet moves through the layer three switch.
3 more elements
A method for moving packets, comprising:
- receiving a packet to a computing device;
- and
- applying error checking techniques independently to different portions of the packet.
A method for moving packets on a computing device, comprising:
- receiving a packet to the computing device;
- providing a first verification key having a first modification complexity to a body of the packet;
- and
- providing a second verification key having a second modification complexity to a header associated with the body.
