Abstract
A method of routing packets between nodes of a packet switched network, the method comprising receiving a packet at a first node, the packet comprising routing information and payload data, sending said routing information to a second node in the routing path via a first transmission medium having a relatively high transmission speed, and sending said payload data to said second node via a second transmission medium having a relatively low transmission speed. Upon receipt of said routing information, said second node is able to prepare or begin preparation for onward routing of the packet in advance of receipt of said payload.
Claims15
A method of routing packets between nodes of a packet switched network, the method comprising:
- receiving a packet at a first node, the packet comprising routing information and payload data;
- sending said routing information to a second node in the routing path via a first transmission medium having a relatively high transmission speed;
- and
- sending said payload data to said second node via a second transmission medium having a relatively low transmission speed,
- wherein, upon receipt of said routing information, said second node prepares or begins preparation for onward routing of the packet in advance of receipt of said payload.
Apparatus for routing packets across a packet switched network and comprising:
- a first egress interface for attachment to a first transmission medium having a relatively high transmission speed;
- a second egress interface for attachment to a second transmission medium having a relatively low transmission speed;
- and
- processing means for sending packet forwarding information across said first transmission medium via said first egress interface, and for sending payload data across said second transmission medium via said second egress interface.
Apparatus for routing packets across a packet switched network and comprising:
- a first ingress interface for attachment to a first transmission medium having a relatively high transmission speed;
- a second ingress interface for attachment to a second transmission medium having a relatively low transmission speed;
- a first egress interface for attachment to a third transmission medium;
- and
- processing means for receiving packet forwarding information across said first transmission medium via said first ingress interface, for using the received packet forwarding information to prepare for onward forwarding of packets subsequently received across said second transmission medium via said second interface, and for forwarding such packets when received, across said third transmission media via said first egress interface.
