A software defined network may operate to provide a variety of trading related services to a variety of customers with a low latency. Core or processor affinity for routing processes may improve speeds of routing. Data capture through a shared memory space may allow for a variety of analytics without introducing unacceptable delay. ## Claims ### Claim 1 A method comprising: controlling, by a first processing device configured to map a local network address and port pair on a first network to a service on a remote second network: opening a first socket to a first destination on a remote second network and opening a second socket to a second destination on the remote second network; balancing direction of incoming traffic to the local network address and port pair between the first destination using the first socket and the second destination using the second socket; and routing incoming traffic to the local network address and port pair to the second destination using the second socket in response to a determination that the first destination is in a fail state; and controlling, by a second processing device: accessing a portion of a memory space shared with the first processing device, in which the portion of the memory space includes at least one of a packet header or an entire packet; and transmitting the at least one of the packet header or the entire packet to an analytics engine while the first processing device routes the entire packet. ### Claim 2 (depends on 1) The method of claim 1, further comprising: controlling, by a third processing device, mapping a second local network address and port pair on a third network to the service on the remote second network. ### Claim 3 (depends on 1) The method of claim 1, in which the balancing occurs in at least one of a round robin or a least connected manner. ### Claim 4 (depends on 1) The method of claim 1, further comprising: controlling, by a routing device: mapping an address and port pair to the first network and a second address and port pair to the second network, in which the routing device is configured such that a third processing device is configured to perform routing to the first network from the second destination and a fourth processing device is configured to perform routing to the second network from the second destination. ### Claim 5 (depends on 4) The method of claim 4, further comprising: controlling, by the first processing device, compressing blocks of data routed to the service according to a dictionary scheme; and controlling, by the routing device, decompressing the blocks of data according to the dictionary scheme for transmission to the service. ### Claim 6 (depends on 4) The method of claim 4, in which the first processing device and the routing device define a software defined network including a plurality of remote data centers. ### Claim 7 (depends on 1) The method of claim 1, further comprising: controlling, by the first processing device, enabling given services from the first network and second network through a software defined network. ### Claim 8 (depends on 1) The method of claim 1, further comprising: controlling, by the first processing device, enabling given devices on the first network to subscribe to services offered to a software defined network. ### Claim 9 (depends on 1) The method of claim 1, in which the service includes a trading customer and the first network includes a network on which an electronic financial exchange resides. ### Claim 10 An apparatus comprising: a first processing device configured to map a local network address and port pair on a first network to a service on a remote second network, in which the first processing device is configured to control: opening a first socket to a first destination on a remote second network and opening a second socket to a second destination on the remote second network; balancing direction of incoming traffic to the local network address and port pair between the first destination using the first socket and the second destination using the second socket; and routing incoming traffic to the local network address and port pair to the second destination using the second socket in response to a determination that the first destination is in a fail state; and a second processing device configured to control: accessing a portion of a memory space shared with the first processing device, in which the portion of the memory space includes at least one of a packet header or an entire packet; and transmitting the at least one of the packet header or the entire packet to an analytics engine while the first processing device routes the entire packet.
