What else can I help you with?
When a host is communicating with multiple applications on the same server at the same time which two values will likely be the same in all packets for each session?
IP address MAC address
What is antispoofing?
Using spoofing, an intruder can fake the source address of his packets and make them look like they originated on the trusted hosts.The basic idea of anti-spoofing protection is to create a firewall rule assigned to the external interface of the firewall that examines source address of all packets crossing that interface coming from outside. If the address belongs to the internal network or the firewall itself, the packet is dropped.
The administrator would identify which address as the address to which all hosts send packets that are destined for an outside network?
10.10.10.6
What happens if a MAC address is not stored in CAM on a switch?
Packets will be transmitted out of all switch ports except for the port where the packets were received. It's called flooding.
What is the purpose of a broadcast address?
A broadcast address is used in computer networking to send data packets to all devices on a specific network segment simultaneously. It allows a single message to be distributed to multiple recipients without needing to send individual packets to each device. This is particularly useful for tasks like network discovery and certain types of communication where all devices need to receive the same information at once. In IPv4, the broadcast address is typically the highest address in a subnet.
How is data passed in packets?
The details vary enormously from protocol to protocol, but the basics are the same for all of them. A stream of data is split into packets, the packet has a header which contains (amongst other things) the destination for the packet. The network uses the destination address to deliver the network to the correct destination.
Sequence the steps in the Port Address translation process?
1. The internal IP address is replaced with the PAT devices's IP address in the request packets source field. 2. A port number is assigned to the connection by the PAT device. 3.The packet is forwarded to the external network. 4. The packet's information is entered into the PAT device's translation table so that all packets sent from the same connection can be translated to that port number.
Constant bit rate in wireless transmission?
it is application level traffic and it gives QoS guarantee.In CBR, source is expected to transmit packets at constant rate and all packets have constant sizes.
How do you calculate packet delivery ratio in MANET?
I think PDR= Packets Received / Packets Sent Packets sent/received values should be from same layer. i.e. all from application layer or network layer...etc
What is broadcast ID?
A broadcast ID, often referred to as a broadcast address, is a special network address used to send data packets to all devices within a specific subnet or network segment. Instead of targeting individual IP addresses, packets sent to the broadcast address are received by all devices on that network, facilitating communication and data sharing. In IPv4 addressing, the broadcast address is typically the highest address in a subnet. For example, in the subnet 192.168.1.0/24, the broadcast address would be 192.168.1.255.
Can CPU handle the broadcast address on LAN?
All load-balancing solutions require system resources to examine incoming packets and make load-balancing decisions, and thus impose an overhead on network performance. [ Dispatcher-based solutions examine, modify, and retransmit packets to particular cluster hosts. (They usually modify IP addresses to retarget packets from a virtual IP address to a particular host's IP address.) In contrast, Network Load Balancing simultaneously delivers incoming packets to all cluster hosts and applies a filtering algorithm that discards packets on all but the desired host. Filtering imposes less overhead on packet delivery than re-routing, which results in lower response time and higher overall throughput.
What three facts are true about the network portion of an IPv4 address?
The IPv4 address is identical for all hosts in a broadcast domain. The IPv4 addresse varies in length. The IPv4 address is used to forward packets.
