The protocol is usually described in terms of a client–server model, but can as easily be used in peer-to-peer relationships where both peers consider the other to be a potential time source. [1]: 20 Implementations send and receive timestamps using the User Datagram Protocol (UDP) on port number 123.
SNMP v3 is implemented on Cisco IOS since release 12.0(3)T. [27]: 52 SNMPv3 may be subject to brute force and dictionary attacks for guessing the authentication keys, or encryption keys, if these keys are generated from short (weak) passwords or passwords that can be found in a dictionary. SNMPv3 allows both providing random uniformly ...
Peer, one of several functional units in the same layer of a network; See Peer group (computer networking) Peer (networking) , a computer system connected to others on a network Peer, a computer network in a voluntary interconnection of administratively separate Internet networks in peering
By definition, peering is the voluntary and free exchange of traffic between two networks, for mutual benefit. If one or both networks believes that there is no longer a mutual benefit, they may decide to cease peering: this is known as depeering. Some of the reasons why one network may wish to depeer another include:
NTCIP Information Level — Information standards define the meaning of data and messages and generally deal with ITS information (rather than information about the communications network). This is similar to defining a dictionary and phrase list within a language. These standards are above the traditional ISO seven-layer OSI model. Information ...
This includes any peer possessing 100% of the data or a web seed. When a downloader starts uploading content, the peer becomes a seed. [citation needed] Seeding refers to leaving a peer's BitTorrent client open and available for additional individuals to download from. Normally, a peer should seed more data than download.
In computer networking, a peer group is a group of functional units in the same layer (see e.g. OSI model) of a network, by analogy with peer group. [1] See also
