network layer

(networking)
(communications subnet layer) The third lowest layer in the OSI seven layer model. The network layer determines routing of packets of data from sender to receiver via the data link layer and is used by the transport layer. The most common network layer protocol is IP.

network layer

The services in the OSI protocol stack (layer 3 of 7) that provide network-to-network (internetworking) for a communications session. Also called the "Internet layer" or "IP layer." See OSI model and Internet Protocol.

Since the peer model directly maps multiple network layer protocol addresses, such as an IPng address or an IP address, algorithmically into an ATM address [15], it can simply set up a connection with this new ATM address without going through the ARP.
Network-layer Attacks: Based on the objective of the attack the network layer attacks are classified commonly into two categories: (i) Routing attacks and (ii) Packet forwarding attacks.
For the purpose of the QXIP, the ME must collect QoS parameters, such as delay, jitter, losses, bandwidth, reliability, Packer-Error-Ratio (PER), Signal-to-Noice-Ratio (SNR), Transmission Power (TP), etc., continuously, at given time intervals (all the time), by collecting the measurements data via cross-layer messages (special XMessage C++ class developet in ns-miracle 1.2.2 for cross-layer communication) from OSI layer 1 up to Lower Network layer, and then storing the data into two-dimensional matrix variable within the QXIP module.
From a user's viewpoint, it can be possible to achieve host migration transparency in the application layer, the transport layer, or the network layer. In case of the application layer approach, name server entries for migrating hosts are updated every movement.
It is very easy to analysis QoS parameters mapping between physical layer and link layer by adjust reference[9] parameters to our proposed method; in this section, based on TCP parameters from literature [5], our emphasis on validating this model between transport layer adopted TCP scheme and network layer. The feasibility and effectiveness of this model for other layers is one of our future works.
Daihinia provides this capability by adding a transparent network layer to the existing network stack in such a way that wireless network connectivity can be expanded by the computers that participate in the Daihinia wireless network.
The work that has been done in ISO TC97/SC6/WG2 on the requirements for Network Layer routing has led to agreement that the aspects of Network Layer routing that are concerned with communication between end systems and intermediate systems on the same subnetwork are separable from the aspects that are concerned with communication among the intermediate systems that connect multiple subnetworks.
Starting from network layer protocols, we will explore issues related to routing and resolution of services to micro-data centres, or computation spots.
The product, called Nokia Traffic Steering Manager, is described as the first "all-inclusive solution to automatically direct traffic to the most effective radio network layer".
The concept of adaptation at the data link layer, network layer, and application layer are considered in 15 peer-reviewed studies.
A system designed to provide Internet protection for children at the network layer has been introduced by Crisp Thinking Limited, a UK company developing solutions for the ISP marketplace to meet the needs of children, teenagers and parents.
The companies said that their expanded relationship involves extensive testing of the new Ethernet network layer later this year, with the planned upgrade of approximately 300 sites during 2012.
